I purchased 11 windows (my whole house) from Window Nation in June 2025. While the salesman seemed…read moreknowledgeable, there are some issues of which I am not satisfied and based on these, I would not recommend Window Nation. First, the energy efficiency of the product is lacking. The salesman, using a sample window and a little device, noted the temperature on one side of the window using the device and then noted the temperature on the other side of the window without the device. A marked difference. However, this winter during a cold spell, my home was quite cold. I had to increase the heating system thermostat temperature to make the home warmer. I put my hand on the inside of several of the windows and surprise, the cold was coming through the window. I had to purchase new thermal drapes to put on windows to try and keep cold out. My utility bills were through the roof this winter so that little gadget was useless. Secondly, when closing an open window, the upper pane slides down with the lower pane and you have to reach up the outside of the windows to push the upper section back into place to be able to lock the window. Lastly, I opted for the 18 month promotion. The service company Window Nation uses is named "Service Finance Company, LLC". THEY ARE A WASTE!!!!!!!! All of their Customer Service Representatives are offshore and when you call, they have no clue how to solve your billing issue. I pay my bills online and since purchasing the windows, I have only had ONE (1) month where I did not have a problem making the payment. All in all, I would suggest that you look elsewhere for windows and not window nation. Oh, and one more item, I received a card in the mail noting a promotion, but 2 get 2 free. Well, it was bogus as the salesman noted that this promotion does not include installation.

They came out and replaced the vent and associated shingles. Great fix! Now, 25 years after moving into this as a new house, I needed a new roof. I got two estimates, one from Marshall. Marshall's representative, Doug, was so thorough and professional in his reprensentation to me and offered a solution re moviing the attic exhaust fan closer to the eave and keeping the ridge vent. The other estimator suggested removing the ridge vent. I wasn't comfortable not having a ridge vent. I again went with Marshall. It was a two day job. They dedicated a more than sufficient crew to the job. The guys were so attentive to protecting against falling shingles as they were stripped from the roof. In short, they did an excellent job! I had absolutely nothing to be concerned about with Marshall's professionalism as a company. And, there cost was lower than my other bid. I only got two bids as my past experience with Marshall and with Doug's representation made it a no-brainer! If you need a roof, go with Marshall.

They have always been thorough and fair…read more Today was the second time I had Marshall help with a roofing issue and, true to form, Jose P. called when he was en route, arrived on time and got right to work. When he discovered a problem that was not foreseen by the estimator he had to run out to get a part but came back promptly and finished the job on schedule. Although this specific element was not included in the original estimate, Jose installed it without fuss and did not charge for the part or his extra labor. Where can you find that kind of responsibility these days? I would never call anyone but Marshall!

Because it is a big project, I actually contacted at least 7-8 companies for quotes and ended up using American windows because of their best price and the best windows brand and glass package. Energy efficiency was my priority so I want the best price and best windows which seems to be very hard. But Jay (the project manager) made sure I got what I wanted. The team went out to install 40 windows and they absolutely did an excellent job. They were super friendly and professional. I'm very neat and detailed so they made sure all windows are cleaned and properly installed. After installing, they vacuumed and even mopped the floor for me. I'm very pleased with their work !

I hired Deckman in March 2023 to build a new deck, and while the construction was completed within…read moretwo months, Deckman failed to follow the proper process for obtaining a permit and scheduling the required county inspection. For over a year and a half, I made multiple attempts to resolve this issue with Deckman, but my communications were repeatedly ignored. As a result, I was left with an unpermitted and non-compliant deck. It was only after obtaining legal representation and sending a demand letter in January 2025 that Deckman finally completed the necessary requirements in March 2025--two years after the initial contract was signed. While I am satisfied with the finished deck and appreciate the efforts of the on-site Project Manager, the lack of responsiveness and failure to fulfill obligations made this an unnecessarily stressful and frustrating experience. I do not recommend Deckman at all.

With regards to the heating of our home, the windows were no better than screens. I reached out, looking for windows and installers. I had a few people come in and estimate the job. None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why. Windows on Washington got the job. My windows and my doors were being manufactured. So they sent out a wonderful gentleman to get the final accurate measurements. Great guy. After that, communication was wonderful as were were assessed of the stage we were in. This included when we got the email and calls explaining that, since we were on a higher floor, they needed to bring in some equipment to lift the new doors up to our balcony. No surprises. Installation day was amazing as Joon and his team came in, got everything into place, and cleaned up the areas to better than when they got here. Joon then went over the features on our windows and even explained how we get to and clean the outsides of the glass. Wonderful man and amazing team. Since then, we have gotten copies of our warranty and the guarantees. And the company has reached out twice to ask if we have any questions and to ensure that we are happy with our windows. We are.

RESPONSIVENESS - very fast, very responsive, very professional. A tad too frequent, but apparently roof repair is a competitive business. INSPECTION - scheduled and conducted efficiently; exceptionally thorough inspection report (David). COST - in line with all other quotes, which are apparently driven by the insurance estimate. Green Oak differentiation included owner interaction, master roofer certification, 5 star rating, excellent warranty, professional documentation and workflow management. WORK - scheduled efficiently, material arrived on time the day before, crew arrived on time the day of, work was conscientious and completed in 3/4 day (townhome), clean-up (including loose nail hunt) was impressively thorough. AFTER - received certificate of completion in a timely manner, along with photo record of repaired roof. Not being a roofer, it's difficult to assess the integrity of the new roof & shingles, however the end result appears clean and professional. Suspect the new, high-quality roof will increase the townhome value and/or decrease time to sell based on the high-quality products used and overall curb appeal of the work. Overall quite satisfied with Green Oak. Recommend.

After a large javelin-sized branch impaled our ~5 year-old roof, all the way through the shingles,…read moresheathing, and paper, my insurance company asked me to get a 3rd party quote to compare to their assessor's. I reached out to Green Oak after searching on Yelp (s/o), and was extremely glad I did. Brian H. took me through the process from start to finish, including an insightful explanation of the insurance claim process. The free estimate happened within a few days and ended up being lower than the insurance-assessed quote. He recommended a roof "tune up" as part of the package without pushing or trying to upsell me for more, which i really appreciated. He also accommodated my inquiry of adding on the installation of a bathroom exhaust vent cap, which was missing when we moved in. After being extremely reasonable on pricing and lighting-fast on responses, they scheduled and completed the work the day after signing. The team was efficient and respectful, with a huge attention to detail. TL;DR - Highly recommend giving Brian and Green Oak Exteriors a shot to help fix your home exterior issues, especially when you are in a bind with your insurance company!

They were super responsive anytime I reached out with questions. Emails and calls were returned quickly, which made the whole process feel smooth and stress-free. They also got someone out pretty fast to measure the windows, so things kept moving without delays. I ordered 10 windows for my townhouse at the end of February, and everything stayed on track. The windows came in April, and installation was set up for the very next week, exactly how they said it would go. The install team (two guys, led by the amazing Mark) was awesome, very professional, worked efficiently, and took the time to protect my floors and furniture. They cleaned up as they went, which I definitely appreciated. Scott, the owner, stayed in touch throughout the day of installation and honestly throughout the whole process. I had a couple of window and sash issues but Scott was amazing and the kind of communication and follow-through really stood out. Overall, I couldn't be happier with the experience. They did exactly what they said they would do, and the customer service was top-notch. I'd definitely recommend ZEN Windows to anyone. It really was a calm, "ZEN-like" experience. Haha!!
