We were very pleased with the work done by Windows On Washington for our insulation project. They were very friendly and did a great job of communicating with us throughout the project. The estimator Shayne was very helpful in providing us and explaining several options for our insulation needs. And the installation team did quality work with attention to detail. Brian, Anthony and Rubin were very willing to explain any details to us as they performed the work and went the extra mile to ensure we were happy with the end result. We recommend them highly

They did not read the description of work to be done. I asked to fix 2 windows. THEY DO NOT DO WINDOWS REPAIR. wasted my time.
Response from

"Windows on Washington does not perform glass or window repairs. We never have, so this is not a new policy. We apologize for any inconvenience this policy has caused you. I'm not sure how we were a waste of your time, considering we did not schedule a consultation for you or consult on your project in any way. We wish you the best of luck with your window repair project."

Our experienced with Windows on Washington from first needing the salesman to our contractor foreman through coordination with the administrative staff. Culminating and extraordinary installation of custom windows - each facet of service provided was professional, high quality, and a pleasure at each steps. I thoroughly recommend Windows on Washington for all who require new windows. The windows are beautiful in appearance, are weather proof, and significantly reduce outdoor noises.

WOW did a fine job. We chose them because of their excellent reviews and because the offered a lower priced door (HGI) that was of equivalent quality to the industry standard door (PROVIA). Because they were short handed and in demand, when we signed with them in at the end of August, they told us to expect a 10-12 week wait for installation. They came out in the first week of November. With the wrong door. The re-scheduled for 2 weeks later; at that time I had recently been exposed to COVID and was under quarantine. The crew declined to come that day even if I offered to stay away from them--fair enough. The next time the were scheduled our installer got sick. Finally the 1st week in December my door was installed. The door looks great. The quality of the work is excellent except for a small problem with the screen door not quite closing right. It looks like they had to door some drilling work on the strike to get it to work, which is a bit unsightly. I was disappointed that the new interior door frame they installed was left raw--no paint. When I called them, the pointed to the section of my contract that said they would leave this in this condition. OK. They met their minimum. If I am paying $6000 for a door from a top quality vendor, I expect them to go above the minimum. So they cannot be expected to bring every possible paint color, but they could have offered to slap on a coat of my paint if I provided it. Note to Angie's list: there needs to be a middle choice for would you hire again. In this case I would not totally rule out WOW. But I would look for another contractor to see if I could get better service than what I experienced.

So this is going to be my first review online and I’ve decided to provide it because of both the size of the projects involved and the quality of service that I received. My family and I recently purchased a 45-year old fixer-upper in Northern Virginia, and the home needed major updates throughout. Two things that needed immediate attention were the original wood windows and the 30+ year old asphalt roof. After a referral from a co-worker, I reached out to Windows on Washington and spoke with Greg for help on the windows. He was very knowledgeable and answered all of our questions, without any pressure to commit on the spot. The windows they use are very well-reviewed (Okna) and offered all of the features we were looking for. His quote for the 40+ windows and one new door was incredibly reasonable and less than other quotes I received. Based on the stellar feedback I’d already received about the company, I agreed to enlist them for the project. Their crew arrived on-time and spent two days doing an exceptional job installing everything. I watched them do the installations and everything was top notch. The windows dramatically improved the look and energy efficiency of the house, and the entire team could not have been more professional. I would HIGHLY recommend this company to anyone if you need replacement windows. During the discussion with Greg about windows, I mentioned the need for a new roof, specifically a new metal roof. He indicated that their company could also handle that project since the president of the company (Eric Novotny) was very knowledgeable about those. I spoke with Eric a couple of days later and discovered that he is part of an expert industry panel for the Metal Roofing Alliance. We went over all the options for installing a metal roof and he came out to our house to talk at length about what we could do. He provided a quote for the project a couple of days later which was very reasonable based on the research I had done and I signed up for that as well. Interestingly, the roof project was completed first (before the windows) and his team spent three days completing everything. The crews worked 12+ hour days to get things done and the work was all top notch. It was beautiful when it was finished and our family couldn’t be happier. As a follow up, two weeks after the roof was completed, I had a chimney cleaning / repair company come out to do some minor work. They ended up severely scratching all of the panels around the chimney in the process and I needed Eric’s team to fix it. He sent two guys out and they spent 12+ hours carefully removing what they had just installed and replacing everything exactly the way it was. I expected the cost for the repair to be significant, but I was very surprised that not only was the cost reasonable, but some of the same crew that did the initial installation were available to come out and do the repairs. It was a very confidence-inspiring extra step and further reassures me that we went with the right company. Overall, I can’t endorse this company and the people I interacted with enough. I didn’t have a single bad experience and I feel like the money we spent was an investment we will enjoy for decades to come. I also know that if something comes up down the road, Eric and his team will be there to help us out. Bill S.

Not well :( . The old basement window needs to be replaced and egress functionality added to it. This contractor isn't interested to perform services on anything less than 5 windows.
Response from

"We specialize in full home window replacements, but have always been happy to serve the needs of our clients that have smaller projects. Due to Covid-19 changes to our business, we require all crews to work as a 4-5 person non-interchangeable pod to maintain their own health and safety, as well as their families and the families of our clients. From a cost perspective, it is not feasible to have a five man crew attend to the installation of one window. Like many small businesses, we have had to adapt and make changes and sacrifices in order to work through the pandemic, and this is one example. We apologize we were unable to accommodate your project request. In the post-pandemic future when our business can be more flexible, we hope to be able to once again take on projects such as yours."

I began my windows replacement project by contacting two bidders, both highly rated on Angie’s List. Windows on Washington helped me learn the terminology and, especially, what to look for in quality windows. I subsequently submitted a draft Statement of Work specifying the models and colors for the 17 windows. Their ensuing proposal captured all that I was after, and its price (with an Angie’s List discount) was comparable to that of their competitor. Both WoW and their competitor offer high quality windows, but not identical ones. Each window has its advantages over the other, and I ended up selecting WoW’s windows based on small differences that were important to me. (Other customers could easily come to the opposite decision depending on what’s important to them.) While there was some recurring pressure to set up a site visit, this was easily deflected until I had made my decision on which windows to purchase. Having selected the windows and thereby the provider, the site visit and consummating a contract were merely procedural steps. Installation was uneventful and took about six hours. The team members were courteous and professional throughout the day, and the team leader was personally invested in providing quality service. I would highly recommend Windows on Washington to others considering replacing their windows.

Consultant came out to provide estimates on multiple projects. I informed that the priority was to replace my sliding glass door and picture window, however I was looking to budget for the other items. He came out on a Friday, August 7th. I reached out to him on on Monday to find out when I could expect a quote and received no response. I then called the office later that day and they pretty much dismissed me stating the consultant doesn't work in the office and that was it. He then texted me on Tuesday informing me there were a couple guys out and he was working from the home office. Again, did not provide me a date of when to expect a quote. Today is 8/17 and I have heard nothing nor do I have a quote. I'm surprised about the lack of response considering this company has good reviews. Unfortunately, I did not have the same experience from the start and would not recommend or entertain any other work by this company.

Overall I give an A because the install crew is excellent, the product is high quality, and they have a great warranty. Two nits however--we had a custom sliding door and it wasn't initially made clear to us that this would add 4 extra weeks for delivery beyond the normal 6-8 weeks which put our install later than expected. It would have been helpful if this was more clearly communicated upfront. Second, the SDLs on the door cause the screen to catch somewhat. It would have been helpful if this had been noted when were deciding between SDL and GBG for the door. It might have landed us on GBG, which also would have been about $500 cheaper.

Terrific experience. At the salesman's recommendation, I purchased a product different (and much less expensive) than the one I had been shopping and which has turned out to be exactly what I needed. The front office kept me informed of each upcoming step in the process, the installer was expert, prompt, and did a perfect job. I couldn't be more pleased with my experience. Highly recommend.

It went excellent! The quality of the work and the installation itself was amazing. We have special window quilts on our windows and they worked carefully around them to ensure they weren't damaged. I would highly recommend them to others.

I highly recommend WoW for window replacement services - although I did not end up choosing them for my project. I called several companies to receive estimates for window replacement. Zach from WoW came out to review my project and provide an estimate for the job. He was totally professional and knowledgeable about all aspects of what I needed. He spent time thoroughly reviewing the windows and frames, answered all my questions, and provided very valuable information and advice on types and brands of windows. He did not talk other brands down but gave an informed comparison about what other brands offered vs. what his brand provided all without any pressure. His estimate was very competitive and for a very high quality window. After conducting exhaustive research on many different brands and types of windows, I found his product to be one of the best on the market. I did not choose it as I simply liked the appearance of a competitor's window. But it was a very close call as I traded off a higher quality window (what Zach was offering) for the appearance of a competitor's window. I also want to add that WoW has a great web site with such valuable information and its President, Eric Novotny actively participates in informational blogs as well. Whether or not you choose WoW for your windows, I highly recommend you contact them as one of your top resources for consideration of their product and their knowledge/information.

I was very pleased with your representative, Zach. He was professional, friendly, knowledgeable and straightforward. He was able to determine that we only needed to replace the window and not the window including the frame. He suggested contacting a glass company that specializes in just replacing the window as his company only does windows with framing. Zach's patience was exemplary in explaining our options so we completely understood the situation. Thank You.

"Thanks for taking the time to share your WoW experience. We proudly give the best advice possible when it comes to home improvement projects - even when it means we don't get the business! Hopefully, you were able to take care of the glass replacement in a cost effective way. Please keep us in mind if and when you're ready for new windows!"

So the front door is *spectacular*. It's the door I wanted for years, a Provia, and while I would've liked to have seen it before buying --the company's "showroom" is really, really basic ---I am very pleased with it. The garage entry door is certified fire rated, and while that is another one I would've like to have seen in person in advance--it is, for example, very heavy and the automatic close mechanism almost knocked us off our feet the first month or two until we figured out how to manage it (key: always keep one arm free and braced), again we are very pleased. A couple things: the sweep on the fire door tore within the first 3 months, even though it was only touching tile (no matter). The installer replaced it, though not without argument, saying it was "just going to happen again" and it was additionally "unneccessary." Someone should have discussed or mentioned this ahead of time. one door lockwas so loose it rattled. The threshold on the front door didn't match the trim when delivered on installation day and it isn't appropriate to ask someone already paying almost $10k for a door to accept this; when things go wrong (and any reasonable homeowner knows they inevitably DO go wrong, and it isn't necessarily someone's fault) just apologize to the customer, instead of blowing it off. A simple "we're sorry" goes a long way. Some equally-simple communication changes-- like when an order is a month late, just call the customer and own it right off -- would have changed a couple B ratings to A's. A year out, and I am still pleased with the result. I would recommend WOW and I would buy from again.

Bottom line - Amazing - I'm so glad I went with WoW - Don't waste your time shopping around. Let's be honest - replacing 36 windows and a patio door isn't going to be fun. Its expensive and a huge pain. The worst part is probably shopping around and meeting with one sales guy after another who spends a ton of time measuring and talking to you about windows until your eyes roll back into your head. Windows on Washington made this process easy - from sales, to support to install. It was as easy as it gets. Sales - no pressure. Honest assessment - no one trying to rip you off or upsell you. Brandon from WoW actually downsold me and told me what I needed and what I didn't need. Talk about earning trust. What's more we completed the visit in 45 minutes - compare that to the large box store that spent 3 hours in my house while he clicked through a million options on his tablet and tried to upsell me again and again. Not to mention WoW had solutions for me - not problems. "Can you do this? Yes, we can do that." That's what I like to hear. Most importantly - it was less expensive and higher quality than that big box store. Ordering/Support - very communicative, very responsive and kept me updated throughout the process. Scheduling the install was easy. Thanks again for making this process painless. Installation - this is the part everyone dreads - almost as much as the sales call. I was told the installers would arrive between 8.30-9.30am. They arrived at 8.31 am and literally attacked my house laying down floor coverings and removing windows and getting the job done. At the end of Day 1 all the windows and the patio door were installed and the house was buttoned up. Day 2 was the final capping and trim work. These guys were amazing. I inspected everything and the work was impeccable. Would I use them again? In a heartbeat.

We work hard everyday to make sure that our clients have a great experience from the time our consultants come on site to provide a quote, to the office processing your order and communicating with you on next steps, and finally to the installers coming out for the main event. It was our pleasure to complete this project and we hope you enjoy the windows and doors for years to come!"

I was so pleasantly surprised on installation day - the installation team showed up right on time and went to work immediately. I've never seen a harder working, better organized work crew on any other project. There was no confusion ... everyone knew exactly what to do and they went about doing it in the most professional manner. Will absolutely hire again for any future needs.

We are very pleased with our overall experience dealing with Windows on Washington. The salespeople were very knowledgeable and helpful, clearly explaining product line differences, the installation process, and differences in replacement window technology. After receiving quotes from three companies who offered different brands of replacement windows we chose Windows on Washington based on the quality of the replacement window they offered and their reputation. On installation day the Windows on Washington crew did an excellent job installing the windows. I was impressed with their attention to detail and the overall quality of their work. One of the primary reasons we selected Windows on Washington was the reviews citing the quality of the work and I was not disappointed. The 19 dual-pane Okna 800 windows they installed look very nice and we are happy with the overall quality of the windows. Compared to the original builder grade 1990 era windows they replaced we noticed an immediate drop in air leakage and solar heating. The windows were installed in the Aug/Sept of 2018, we are very happy with both their warm and cold weather performance.

I had multiple quotes from different companies and decided to use Windows on Washington. I feel the installers are highly competent and allowed me to ask multiple questions during the install.

Great job to the folks at WOW. Zach came in and was extremely friendly and helpful. He knew everything there was about the options available. (Sliding glass versus hinged, color options, levels of doors, etc). The installers (Young?)- I know I spelled that wrong.. they were exceptional and very friendly. They came in that afternoon and were gone in a day. If I have any other projects I will be using the company. Well done!

Amazing all throughout the whole process, sales person was knowledgeable and nice. Had a small issue which was resolved quickly and communicating was always easy to do. Every single person responded to emails which was refreshing too. Windows are great and the install went smooth as well-actually ahead of schedule since it only took about 5-6 hours.
