Custom windows and doors, installed across Northeast Ohio by our in‑house team.

Before and after of an Avon, Ohio home with a new ProVia entry door and Okna windows installed by Window Universe Cleveland.

Remodeling your home is about more than just choosing the right products, it’s about making sure they’re measured and installed the right way. That’s why every project we take on starts with custom-sized windows and doors, designed to fit your home perfectly.

One of our professional installers will measure everything to the 1/8”, so whether it’s a ProVia entry door, an Okna vinyl window, or a Marvin wood or fiberglass window, every product is measured to fit with exact precision.. That precision means a better seal against drafts, smoother operation, and a finished look that feels like it’s always been part of your home.

From the first measurement to the final install, everything was precise and professional. Our new door fits perfectly and makes the whole entryway look brand new.” – Avon homeowner

From Brunswick to Beachwood, homeowners across Greater Cleveland trust us for entry door replacement and window upgrades that boost curb appeal, comfort, and efficiency.

— ★ —

Great products can underperform if they aren’t installed correctly. That’s why our crews are trained and certified to follow manufacturer guidelines down to the smallest detail. We use the industry’s best materials — OSI Quad sealants, insulating foams, and Performance G8 exterior trim coil — to make sure your new windows and doors stay energy-efficient and watertight for the long haul.

Just as important, we treat every home with care. Inside, we protect floors and furniture with drop cloths; outside, we lay tarps to catch dust and debris. Our installers finish every project by wiping down surfaces and vacuuming work areas, so the only thing you notice is the upgrade.

“The crew was polite, laid down drop cloths, and cleaned up so well you’d never know they were here. The windows look fantastic and the house feels warmer already.” – Cleveland Heights homeowner

Whether it’s a classic wood replacement window in Oberlin, a patio door in Medina, or a full-home project in Mentor, our labor is covered for life, a level of protection most companies only offer for a year or two. Combine that with some of the strongest manufacturer warranties in the industry, and it’s clear why homeowners trust us: we stand behind our work, and your investment is protected.

Did the research and WU came back highly rated, as did Okna windows. Got over a dozen windows 2 years ago and have been very pleased with the quality of the product and the installation. Needed one for a bathroom project and a front door. Adam ( from prior job) & Lou came out. Friendly and very professional. Answered any questions and explained process as they went. WU is not a chain. These guys are not sub contractor/installers. Fiberglass wood look door is beautiful.

Very pleased with Window Universe! Great service, low pressure sales, good pricing, efficient and friendly installers and quality windows. They have it all! From Lance with sales to Donovan and Adam installing, I couldn’t have been happier.
Windows work and look great and they cleaned everything up inside and out.

Window Universe was amazing to work with on our new windows. They were straightforward and honest about their pricing. No crazy mark ups and then "big sales" - just a high integrity company who does right by their customers. They communicated every step of the way, were flexible with installation timelines, and did a great job installing and cleaning up. Best experience possible as far as home renovations are concerned. Do yourself a favor, skip the big companies with flashy sales that are still crazy expensive, and call Window Universe. You will be so glad you did.

Great experience from initial meeting with Sales to final installation. We had whole house window replacement that included a large bow window plus a garage entry door replaced. Chad provided no pressure sales and was very informative about the entire process. Lou and the team of installers were on time and very respectful of my house including floor coverings and cleanup. Installers were quick and efficient and left my house exactly as it was. The final product is beautiful and I highly recommend them if you're looking for windows. Thanks Window Universe!

We could not be happier with our new windows! I have to admit I was a bit anxious about the installation process but Adam G., Joe B., and Drew H. were not only very friendly but their skill set was amazing. The install was done efficiently and professionally. With help from Chad we chose a window style and color that is in keeping with our OLD storybook Tudor home- the windows look like they belong in this old house. The product quality is outstanding, exceeding our expectations. From the initial proposal, to the weekly updates, to the install team -the customer service that Window Universe provided was second to none! Thanks so much for a wonderful experience.

We could not be more pleased with the work and care that Lou, Adam, and Drew took while working on our home. We have a brick colonial century home, and Lance understood our vision from the first consultation. He knew exactly how to preserve the style of the home, while giving us all the benefits of the great quality product that they installed. The crew was thorough and meticulous. They left no evidence that they were even here! They took great care of our home and exceeded our expectations. I would highly recommend them to anyone interested in replacing their windows.

10/10 - we had purchased windows at our last house / this experience was so so much better.

From the easy sales process, updates on progress through production, and then the installation team we had. Absolutely outstanding customer service.

The team was not only courteous to our family (and loved on our dog) they were so polite to each other. The work they did was meticulous and they worked hard from when they got here until they left.

It started with Lance coming to give me an estimate and following up to answer all my questions. Then Adam G., Eli W., & Donovan K. came and installed my sliding door and windows. They were on time, professional, funny, informative and cleaned up after the project. I highly recommend this company and these installers! They know the window business!

From the initial contact to when they drove away they were the most friendly, professional, and high quality company I’ve ever had work on my home. I cannot recommend highly enough!!!!! They took such pride in their work and truly cared about what they were installing and it showed. The warranty is included in the price and totally worth it. There was no sales pitch or “discounts”. Communication was very clear and regular. They were on time every time. And of course our new windows and doors are beautiful! I literally have nothing negative to say about Window Universe. I’ll use them for everything I can in the future.

Will, Joe, and Drew were the best! They came in and installed my living room and dining room windows in one day. The next day the installed my doors. Both are beautiful! Each of my installers always stopped to answer any and all questions that I had. I would recommend this business any time!

Very complete and orderly estimate process. No hard salės. Fair price. It took about 6 weeks to get windows manufactured. Install crew was on time and Very neat. Quality of the installation and windows was very good. Already had Allside windows on other side of house. They are good. These are better.

My husband and I were so impressed with Window Universe the first time we used them, we knew we had to use them again for our new house! The entire team has been very professional, knowledgeable, and friendly. Calvin, Joe, and Donovan were fantastic! When anyone ever talks about wanting to get new windows and doors, all my husband and I say is “You’ve got to go with Window Universe! They are fantastic!”

We used Window Universe to replace our 20+ year old windows. They kept us in the loop through the whole process, which was great! They also made sure that we were happy with our end product. We had a concern with the look of the windows after they were installed. They heard our concerns and offered a few options. In the end they made sure we were happy with our windows, even at a cost to them.

We were very happy with the installers Joe and Drew. They were courteous and we were pleased with the job they did. They installed all eleven windows inside the first day and finished the outside trim the next day with minimal interruption to our daily routine. Joe explained the operation of the windows as well as the warranty. I would recommend Window Universe to anyone.

Window Universe did a great job. New windows make the house look much better. 10/10 experience from start to finish.

Response from the owner 18:20 05 Aug 25

Thanks so much for the review! We're glad to hear you're happy with how the new windows turned out, it’s always great when a project gives the whole house a fresh look. We appreciate the 10/10 and the opportunity to work with you!

Awesome experience start to finish! Clear communication, detailed quote, competitive pricing and communication weekly once materials were ordered. We had a front door, large second story window, three panel sliding door, and 17 other windows replaced. The team that did the install was polite, punctual and extremely hard working. After four days, they never left a mess, made sure we knew how to work everything and were an overall pleasure. We could hardly tell they had been there after they left. Highly recommend Window Universe!

Response from the owner 12:43 21 Jul 25

Thanks so much for your review and for sharing those incredible before-and-after photos! We’re thrilled you’re happy with how everything turned out. The updated black trim on your front entry and sliding door looks fantastic and really ties the whole look together.It means a lot to hear that the process felt smooth from start to finish. We put a lot of focus on making home improvement projects feel manageable and well-organized, from clear communication upfront to keeping you in the loop during production.We're also especially glad you appreciated the work of our installers. They’re full-time members of our team (never subcontracted), and we’re proud of the skill and care they bring to every job.Thanks again for the kind words and the recommendation. We’ll be sure to pass your feedback along to everyone involved!

Fantastic! Have a condo with old custom not efficient aluminum frames. To replace these sliding doors and windows the condo association is specific to color and trim inside and out. A friend had hired them and suggested I call them. The process took 8 weeks but was very smooth, accepted my credit card without any additional fees like it should be. They didn't ask for final payment until they were completed and finished. Went over the windows how to clean etc. They also said anything happens with anything, just call us for the life of the window. What more can you ask for? Great job men!

Response from the owner 12:19 15 Jul 25

Thank you for the great review! We’re so glad to hear everything went smoothly and that the final result met both your expectations and your condo association’s requirements. We know how important it is to get those details right, especially with custom replacements.We also really appreciate the referral from your friend—word of mouth means a lot to us. Our team works hard to make the process straightforward from start to finish, and it’s great to know that came through. We’ll be sure to pass your feedback along to the crew. Thanks again for choosing us!

Window Universe Cleveland truly exceeded our expectations when they replaced our back door. Everyone we interacted with from Window Universe was great! The rip-out and installation process was efficient and expertly handled by their team. The installers were timely, skilled, and incredibly attentive to detail. I particularly valued their clear explanation of the warranty before they left. We are absolutely delighted with the quality and appearance of our new door, and I wholeheartedly recommend their services!

Response from the owner 12:17 15 Jul 25

Thank you so much for the kind and thoughtful review! We're thrilled to hear you're happy with your new door and that the entire experience exceeded your expectations.Our installers will especially appreciate your feedback.

It's great to hear their attention to detail and professionalism stood out.Thanks again for your recommendation and for trusting us with your project!

We did a whole-house replacement of all of our windows and couldn't have asked for a better experience. The communication was great throughout the process, the installers were professional, and our windows look great. We would definitely recommend Window Universe to anyone shopping for replacement windows.

I had an excellent experience throughout the process of ordering and getting my sliding glass patio door and upstairs bedroom window installed! From the initial interaction of calling to set up an estimate appointment, to meeting with Lance to figure out what I was looking for, to having the guys come out and install everything, every single employee I dealt with was extremely kind and efficient and a pleasure to work with. Highly Recommend!

Response from the owner 20:32 10 Jul 25

If you're looking for new windows or a patio door, look no further. Windows Universe took all the uncertainty out of buying new windows. After getting estimates from two other well known window dealers in the area, it was very refreshing to have Windows Universe come to our home and give us a very straight forward, fair and honest estimate for our windows and patio door. Their approach to window sales is different from all the rest. They addressed my concerns, discussed options leaving me well informed and completed our visit in 45 minutes with a ”Thank you for your time” and “give us a call if you’re interested.” None of the “other guys” high pressure tactics and games. No “tonight only” deals or a starting on Mars price to eventually bring it down to Earth. One of my other estimates lasted nearly 4 hours!
A real, no hassle lifetime warranty is all part of the deal. They walk the walk as proven to me when they replaced our new patio door with another because of a few issues that I was dissatisfied with. They could have just as easily said “live with it” and went on their way.
Everyone I dealt with at Windows Universe - from the owner, in-home sales, office staff and installers were all courteous and professional at all times.
If you’re in the market for windows or doors, give Windows Universe a call, you won’t be disappointed. - Paul

We had a great experience with Window Universe! It started with our initial consultation with Chad. The whole process was great, and he was so helpful. There was no high pressure selling. We were thrilled with their reasonable pricing and the high quality of the windows. We received weekly updates on the progress of our order which were very helpful. The order arrived well before expected. The measurement and install teams were professional, personable, and organized. They completed our entire install in 2 days, as scheduled. We highly recommend Window Universe for your replacement window needs.

Response from the owner 14:02 08 May 25

Everything about Windows Universe was great from the quoting process, measure, manufacturing to installation. First started with my awesome Sales Rep Lance who understood my needs and provided a straight forward quote. I stopped by the showroom to see the windows in person and Lance greeted me gave me a walk through and I made the purchase on the spot. The price was very competitive in comparison to the competitor with the name in reverse :). After purchase Dustin came out for some official final measurements and I received weekly emails on the status of my windows and patio doors. About 8 weeks later I got the call your windows are in and installation was scheduled for the following week. The installation team arrived on time and were very professional and all worked well and treated my home like it was their own home. If you are looking for replacement windows for your home look no further and call Lance!
