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!!

I had a wonderful experience with A.R. Glass. Eddie repaired the torn screen on my sliding glass…read moredoor, in addition to adjusting it so that it would finally close properly and lock. He also replaced four glass panes on three windows where the seal was broken and fogging up. His measurements were perfect and the new glass looks amazing. He told me that the frames were in good shape which was relief as the windows are 24 years old. Eddie cleaned the glass, tightened up the locking mechanism, and left no trash or debris behind. Eddie has a great work ethic, takes pride in his work, and is a nice person. He also responds quickly and his prices are very fair. Highly recommend.

During the process of renovating my entire house, I found Anthony's company through Home Advisor as a quality and affordable alternative to the big name companies that have a lot of overhead to cover. The company is licensed, bonded, and insured and locally owned and operated, so support local businesses! The experience with Anthony was very positive, from having the initial in-home consultation to receiving a quote to getting the installation scheduled and completed. There is no pushy sales tactic here; only professionalism and honesty. My front door and kitchen doors were installed in a day, are sturdy and well constructed, look fabulous, and keep the cold air out. I chose a very modern deep red door with rectangular windows. The installation has overall skyrocketed my home's curb appeal. It's the best door in the neighborhood thanks to Anthony. I highly recommend Anthony and Beltway Exteriors for all of your home needs (including windows, siding, gutters, driveways, and much more).

The installation was done professionally and relatively fast for both doors and the bars on the windows (took 3 days). It did take a while for the installation materials to arrive, which resulted in delayed installation dates, but I believe that the rainy weather had a lot to do with that as well. Overall, I would definitely recommend the services of Beltway Exteriors.
