Keith got back to me very quickly, was knowledgeable about the products, and offered competitive pricing. He took the time to understand the unique qualities of my roof to ensure that everything would be taken care of perfectly. Once the permit came through, he was able to get his team out quickly and they did a great job installing the roof (done in a day!) Keith and his crew were professional, timely, and kind. When a small flashing issue popped up several months later, Keith sent a team out to fix it ASAP. I would recommend this company to anyone looking for great service and quality. I'm going to be reaching out for a new security door soon!

I had a really great experience with ZEN Windows from start to finish. What I liked right away was…read morehow casual and easy everything felt, no pushy sales tactics, just straightforward and friendly communication. 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!!

The cleanup looked great--everything from yard furniture to our flags was returned to the correct place--and the roof looks beautiful. Tim explained the work and set reasonable expectations and I thank him for that. I would gladly recommend Seneca Creek to a friend or neighbor.

Had my gutters serviced today. Used the Groupon deal so it was very affordable. I called and at…read morefirst it was their answering service that answered. Apparently they are unfamiliar with the fact that they are on Groupon so I had to call back when someone from the company was in the office to get on the schedule. They had availability for two weeks later. I wasn't in a rush so I don't mind the wait. I wasn't scheduled for the 12-4 time window. On the day of I had a work commitment that came up last minute. They were very accommodating when I called so I was pushed further back on the timeslot till after 3 PM so I could be home for the service. The technician Isaiah arrived and informed me what he was going to do. Afterwards he sent me a detailed report with photographs of my gutter system. Thankfully, everything looked good and I did not require any additional services after the cleaning and tuneup.

I am so happy with my new windows, and especially with my new sliding glass door installed my…read moreAmerican Home Contractors last week. For the first time I realize I had been hearing a fair amount of outside noise (which I'd apparently gotten used to), because these windows/doors are soundproof; now I don't hear anything at all from outside! And even better, the windows are easy to open, and my sliding glass doors actually slide well in the track, and are not shaking and drafty when it's windy outside -- major improvements from my old, builder-grade, 20+ year-old windows/sliding door. Further, the service crew was excellent -- careful, kind, professional, efficient, and they cleaned up everything afterwards. Roger, the foreman, has been doing this work for almost 30 years, and Jose, who single-handedly carried in/out the windows/doors, has been doing this work for 10+ years. I didn't get the name of the quiet third service person who was mostly outside and on the ladders, also very efficient. fyi, they did mention that working on the 4th floor of our condos from ladders was a bit more challenging as the original builder-grade windows had been made to fit by being packed/taped in place from the outside, which necessitated them having to actually break some of the glass to be able to pull the old windows out. But they did it - and did it well. Finally, Shaun, the project manager who gave me my estimate and oversaw the project from estimate, HOA approval process, to completion, was great. Highly recommended.

He came 3/4 times over year of planning, due to our time and other ongoing projects before the contract signing. Carlos and his team installed the Siding.

I am very happy with this company, their professionalism, and the quality of work.

Given the cost of the custom door, I'm not certain I would recommend this company at present…read more First, the estimate came in a bit lower than their competitors, which was a plus. However, the sales associate missed a few details and later tried to encourage us to pay more, although the contract was ratified. We refused and were prepared to cancel the order. He later came back to say that his boss assumed the additional fee. We were promised the door in 4-6 weeks, but it has now been several months. We received an email that the door would arrive at their warehouse by 2/26/26, yet as of today 2/28, there has been NO communication. If the door is installed, I'll update the status on the installation and quality of the door. At present, I'm not certain that I would recommend American Windows.
