At New Jersey Siding & Windows, Inc., homeowners can choose from wood or vinyl replacement windows in 10 different styles, including:

  • Double hung: The most popular style of window, this window requires less maintenance.
  • Casement: A crank mechanism swings this window open from the sides on hinges. Providing the tightest seal, this style is the most energy-efficient window we offer.
  • Slider: The placement of the sash makes the horizontal opening smooth and easy.
  • Awning: Similar to a casement window, this window cranks outward, as the hinge is fastened to the top of the window.
  • Bay: Typically composed of three windows, this window protrudes from the home, either tied into existing roof, or with a stand alone roof built over it. Bay and bow windows make living spaces feel more spacious.
  • Garden: This window sticks in a similar fashion to bay windows and is perfect for plants and herbs. The sloped roof allows maximum sunlight without risking water buildup.
  • Bow: Similar to bay windows, this style often has more windows and is a great choice for living and dining rooms.
  • Picture: A fixed window that does not open, picture windows are great in spaces where you need plenty of glass.
  • Specialty: These vinyl windows are tailored to any specific needs your project requires.

$500 off of a qualifying purchase of five windows or more.

In the 2 years we've owned our condo in Hoboken, we've had to replace the windows, floors, HVAC, both bathrooms, kitchen appliances, and washer/dryer. New Jersey Siding and Windows is by far the BEST contractor in the state. They did incredible work installing the windows originally, but also come back for any touch ups needed. For example, some of the caulk was peeling and they sent Yaron out. He touched up around all of our windows and they're once again looking brand new. Highly recommend New Jersey Siding and Windows!
Response from the owner: Erika, we’re thrilled that you’re happy with the work, and thank you so much for the kind words. -Andrew
Thank you, thank you, thank you to Mickey and the crew at NJ Siding and Windows. We installed SoftLite windows and sliders in our home about 20 years ago. They have served us very well, but recently a handle broke on a window and the screen on the door no longer closed. We thought we were going to have to replace the window and the door, but NJ Siding and Windows came to the house and repaired both in minutes. They were a pleasure to work with!!
Response from the owner: Thank you for the kind words Debbie. We’re so happy that we were able to help! -Andrew
The best
Daniel Raia was pleasant, knowledgeable and responsive. This is the second time that we have used this company. The bay window and the sliding door were very high quality. The installation was professional and clean.
Unbeatable quality, service and workmanship. From the initial appointment, to the install, was simple, professional, and overall high quality in every aspect. Constantly get compliments from neighbors on the front door that we bought, which really makes our home stand out. 100% would use again
I used these guys to replace a bay window 4 years ago and it was done so professionally and neatly. I dealt with Dan R. then who is a great and knowledgeable guy. I just agreed to do another 5 windows and my rear slider. I’d definitely recommend them and ask for Dan!
For several years I put up with a cracked window and the others foggy. I finally decided to do something and now wish I had done so sooner. The consultant from New Jersey Siding and Windows listened to what I wanted to do and presented a perfect solution. She also assisted me to setup a payment plan with a recommended group. The gentlemen who came to install were friendly, fast and cleaned up all debris. The whole process fantastic and now the sunshine pours into the room. As the winter cold temperatures have started, the sun room still feels warm. I’ve shared some before and after photos. I plan to replace more windows in the future. I highly recommend this company!!!
Response from the owner: Thank you so much for the kind words Shawna, and we are thrilled that you're so happy. Have a wonderful rest of the holiday season.
Great management & customer service!!! Had an issue with the vinyl siding a couple years after install which was product related. Mickey worked endlessly with the manufacturer who was being very difficult and got it resolved and replaced.
This is our 2nd time using them, our first time was 7 years ago for 9 windows which have held up AMAZINGLY!!!When I called to schedule this appointment I was told that the sales guy Dan, who I worked with before would be back.I wouldn't go anywhere else for windows. They are doing our back door, storm door and 6 windows currently and I was told that he would ask that we have the same crew as last time.
Nj siding and windowRandolph njGreat job on replacing our bow window!!Start to finishVery pleased
Just finished my siding project. The workers did a great job on my home. It looks like a brand new house. They installed all of my new fixtures and everything works perfectly. Even the man delivering the dumpster said that I selected one of the best siding installers. He said “ I see them all and this company is the best”. It only took one week to transform my home.I definitely highly recommend this company.
I couldn't be happier with the sliding door! The team @ NJ Window and Siding were extremely professional from my first phone call to installation. The job was completed in such a professional way that pictures wouldn't even do it justice. I strongly recommend using them.
I used New Jersey Siding & Windows to replace my sliding glass door. The entire process was seamless from meeting with the sales team and selecting the door to the installation. They would keep me updated on the status of my order and when the installation could happen. The techs who installed the door were friendly as well. When they left, they cleaned so well you would have never known there was someone even there if it wasn't for the amazing looking new door.I will absolutely be bringing them back when I need more work done.
Response from the owner: Thanks Todd!
Great sales guy, Dan. Installer, Ronnie and everyone I've spoken to at the office. Excellent work! Got all our house windows, then 2 years later got our porch sliding windows!. Very Happy!
Response from the owner: Thanks Joe! We appreciate the kind words!
My wife and I met with Daniel Raia of New Jersey Siding & Windows to discuss our siding options and other details. After sitting and speaking with him for some time we had no doubt that N.J. Siding & Windows was the right choice for us. Daniel was personable and very professional. He assured us, the team who would be sent to work on our house would be proficient & work in a timely manner. From my wife and I both, Thank you Daniel & thank you to the team of guys who helped us update our home! Everything turned out incredible, as expected.
Response from the owner: Thank you Marcello! Your house looks great!
Excellent service and installation. Salesman Dan was wonderful and extremely helpful. Installation was done professionally and accurately. Great company to do business with and this is my second time.
We used NJ Siding & Windows 10 years ago to replace our second floor windows. We had such a good experience, that we've used them again to replace our first floor windows and to replace some damaged siding on our house (siding was on the house when we purchased it, so not sure who installed it). Dan Raia was our sales rep the first time and came back for round two -- so they even take care of their employees! Dan was again a pleasure to work with as well as Steven, who took the measurements of everything.I definitely recommend NJ Siding & Windows -- they provide quality windows by skilled installers at a fair price, a lifetime warranty and are easy to work with. What more could you ask?
I couldn’t be happier with my new siding and customer experience from NJ Windows & Siding! So much so, I went back to them when I decided to add a sliding door to my home. For my siding, my experience started with their salesperson Dan, who was knowledgeable, transparent, and fair. I was happy with the contract and the installation was smooth and high quality. My house looks amazing! Moreover, when we had a possible raccoon in the attic shortly after installation, they offered to come and remove the soffits temporarily at no charge. (Luckily it was a false alarm.) This is to say they really do guarantee their work and go above and beyond. Now with my second job with them, I worked with Dan again and the process to get exactly what I wanted at a good price went smoothly! Excellent customer service, high quality work, fair pricing. OUTSTANDING! 10/10 highly recommend!
This company is great. They do nice work with my windows, now I'm using them for my roof and siding.
I had NJ siding and windows do windows for us a few years ago, then new siding last year and now a new entry door this year. Dealt with Dan to get quotes each time and always got prompt responses from him on any questions. As far as the workmenship, their people did a great job on everything that they touched. Would recommend them to do work anytime.
Company replaced the windows on the 2nd floor of my house and they did a great job!
We had NJ Siding and Windows replace all of the windows in our roxbury home, including a bay window and a sliding door. The install was completed by Ronnie and Elliot over the course of 3 days. They were extremely professional and courteous, and did excellent work.Paul was our salesman and he was also extremely professional and courteous. When I first reached our for pricing I asked to please respect my time and not tell me every single thing about the windows - just give me the gist of it and get me the pricing, and if I have questions I'll ask. Paul was so respectful of my time and was very mindful of not going into detail unless I asked for it. The same can't be said for other companies who I was considering at the time, and indeed this was one of the reasons why I chose NJ Siding and Window.As for the final install and quality of the windows, they look great and even better, they feel great. We immediately felt a difference when night fell and it was cold and windy outside.I would 100% recommend NJ siding and windows
We had to have all the windows and a sliding glass door replaced in our new house. New Jersey Siding & Windows did an amazing job! The salesman, Stan, was so knowledgable and informative and not pushy at all. The crew that did the install, lead by Ed, were so professional and respectful of our property and they were in and out in one day. There was no garbage or debris to clean up, it was like they were never here. We will be looking for siding next and will definitely be using New Jersey Siding & Windows. I can’t recommend them enough.
Wonderful staff and great products! Fast turn around time. Very friendly and accommodating. Quick and clean install. Thales have now done our whole house- window and doors. Highly recommend!
Great customer service!
I normally never write reviews, but after my experience with NJ Siding and Windows I had to speak abut how amazing they were every step of the way. My experience with Steve, who came out to start the process was amazing. He spent over 3 hours with me, showing me all the products, colors and choices I had for my home. By the end of the visit I had a complete plan to redo my siding, windows and totally overhaul my front porch. When it was time to start the project, I was amazed at how effortless it was to replace my windows and front door. They were neat, clean and very respectful of my home. The crew chief Marcus and his team were amazing. They paid attention to every detail and when they noticed something was not right they stopped, reviewed it and came up with a plan to correct it, even if it meant redoing the work they had already done. Mickey in the front office was very responsive and helpful. I am so happy with the end result. The house looks brand new and everything I had asked for came out beautiful. Thank you NJ SIding and Windows!
They sided my house.Very happy with job.Fair price and excellent work.They arrived on time ,and finished on timeI Would recommend
Had (7) windows replaced recently and everything was amazing. The installers were great, super knowledgeable, and let me know everything they were doing and why. Very infomrative. It was clear they were going for quality, because he was showing me the shotty worksmanship of the previous installers. A+ all around. (3) of the screens were damaged on arrival, so I can not fault the installers for that one, but the technician noticedit and brought it to my attetion. So I appreicate that. We have 2 sliding doors that need to be replaced, so we will be contcating them for that job as well. Highly recommended.
Best experience and work was excellent very helpful from start to finish ! If you’re looking to get the job done correct the first time this is the company.
NJ Window & Siding has done my windows, siding and gutters over the last 10 years. Truly a reputable business that uses quality products, stands behind their work and is truly customer focused! I cannot recommend them enough noting they have been in business for well over twenty years. Kudos to Mickey, Kathy and Taron for providing truly professional services to their clients!!!! Hope you all the best for the next twenty years!
I highly recommend this team--no high-pressure sales tactics, good price for a good product. Paul really worked with us on finding the best options within budget that really fit our home. The installation team was was fast, clean and friendly.
A few years ago NJS&W did a quality job on a replacement slider for our Breakfast Nook. So, when we needed all five of the windows in the nook replaced, we only reached out to them. I was surprised at how quickly they were able to get the windows we selected -- after all the supply chain horror stories we've been hearing. The windows were installed yesterday and they look great. Many thanks from a highly satisfied customer. PS -- The price was great, too!
Response from the owner: Rudi,We appreciate the kind words and your business as a customer. -Andrew
I have used NJ Siding & Windows twice in the past few years. First to replace a custom interior foyer door & a sliding patio door and most recently for a large improvement project to replace roof, windows, front door, and siding. Due to COVID, we had some delays with material but once everything came in the project started, was well managed, great communication, no extra costs, and done to perfection. From Nick the salesman , to Kathie in the office , to Mickey managing the crews, and Matt in financing and Andrew - this is a top notch business. Quality materials, excellent sub contractors and premier customer service. I highly recommend this company. Thank you for exceeding my expectations!! And I would not hesitate in using them again.
We had Kim as our contact when choosing a new door. She was very attentive and helpful throughout the entire process. Highly suggest asking for her if you have any door/window needs.
Kim helped me and replaced my windows and made the whole process incredibly easy and stress free. With the new windows it’s definitely much quieter and keeps the house at the desired temperate which is much needed no matter the time of year. All in all i can not say enough how amazing this company is and if you’re planning on doing any updates or replacing I highly recommend them and requesting Kim. You won’t be disappointed
I have used NJ Siding and Windows for several projects over the years. From windows to doors to roofing each project has been amazing. The sales rep Kim is very personable amd extremely knowledgeable and I didn't feel pressured at all, I would def ask for her when setting an appointment! I have dealt with several of their install teams and each one has been top notch
I previously had my windows done with them and it came out fantastic. Now I currently had my siding upgraded and added some stone and the teams that engage us were phenomenal, communicated every step of the process. Easy to get ahold of. They have exceptional customer service - the focus from the beginning was about making us happy. The prices are competitive and because I dealt with them previously with windows I know there service is top notch.My house looks great, I know these guys aren’t going anywhere, I know I paid a fair price and I know that they will honor their work and their service is ultimately why I returned to them for work on my siding.
After meeting with numerous contractors, and feeling like we were getting nowhere, we had the very fortunate experience of meeting with Paul from New Jersey Siding and Windows.He listened to all of our needs, clearly heard what we were actually looking for, and began guiding us towards the right solution. Even though our house was a challenging project, he and Mickey were extraordinarily motivated to make our house beautiful. From start to finish, their entire companies’ consultative approach was extraordinarily helpful in guiding my wife and I to the absolute perfect design for our home. We could not be more thrilled with the outstanding job they did. Outstanding materials, great price, surpassed our expectations. They turned our very plain house into a very beautiful, unique looking one. Highly recommend!!!
Recommend New Jersey Siding & Windows. Matt and his team were very professional and helpful in picking out a new front window for our house. The day of installations they were on time and worked efficiently. When they were done you couldn't even tell our window was replaced. They left the area cleaner then when they got there. We will definitely be using them in the future to replace more of our windows.
We purchased a Soft-lite Kingsroyal sliding door that we're really happy with. The price was competitive for triple pane, which not every company offers. The delivery was pretty close to the originally scheduled date, which is rare in this current environment. Install team was clean and professional, and they were able to install without any damage to our new molding that was just put in a few months earlier. We can already notice the difference from our old drafty door this winter. Thanks.
We replaced all of our windows and sliders and we couldn’t be more pleased with them along with the professionalism of the employees. I was amazed how much care they took in making sure they not only did a good job, but how meticulous they were at keeping our home clean while working. NJS+W’s is a company that does amazing work and I highly recommend them.
On January 24, 2022 my mother had a new picture window installed. I want to say what a pleasant experience it was to deal with N.J. Windows. Beginning with Kim who is perfect in the job she does to the installers, Ronnie and his partner who were pleasant, personable and quite adept at their jobs and all a credit to the company!
Tito and the siding crew of NJ Siding & Windows, Inc. are committed to the best service possible in the industry. They did the job securely, quickly, answered all questions, and cleaned up after the completion. The finished project was a sight to behold. It is both practical in design as well as aesthetically awe-inspiring. The office staff, including Mickey, were always available with any questions or concerns. Their prices are fair and their work ethic unsurpassed. I am incredibly pleased and highly recommend this company.
Such an amazing experience with this company. From start to finish, we were never worried about anything in what easily could have been a very daunting process. They made the entire job as seamless as possible, even given the long Covid-imposed wait time for materials. We shopped around extensively for companies to handle all of our siding, windows and roofing needs and NJ Siding & Windows gave us the best options, at the best price, and made us feel the most comfortable. 10 of 10 would use again!
Just had an excellent experience with NJ Siding & Windows. Had eight window replacements ordered and installed without a hitch. Windows are beautiful triple paned (I live on a busy street) and I can't explain how quiet my house is now. My salesperson, Kim Flannelly, explained all of the advantages and she was so right. Two installers - one inside, one outside - did a perfect installation and cleaned away all of the debris before they left. Highly recommend this firm!
We cannot say enough great things about New Jersey Siding & Windows! They re-sided our 1960s ranch, replaced our brick front with stone, and our gutters. After two years, the siding is just as great as it was once installed. There has been no warping, no fading, or leakage from the gutters. The workers were here on time and stuck to their schedule. They even moved our schedule up after a cancellation since they knew I was expecting soon. Now, we called them again to patch a window we closed to make way for our new bathroom. The customer service has been nothing short of phenomenal and we cannot wait for them to complete another perfect job. We highly recommend New Jersey Siding and Windows!
