Get matched with top window and door contractors in Colesville, MD

"Bottom Line: This is the first time we have used this company, and they did excellent work for a reasonable price, and more importantly, built a huge amount of trust with the customer. Communication: Scheduling the initial estimate was easy, but the back-and-forth communication required to finalize the many detailed options was a bit slow; however, the owner Scott Halle interceded and timely communication continued throughout the rest of the process. Scoping Work: This is where Zen Windows really excels, primarily because of the vast knowledge of James Bond. We wanted to replace the single door with side transoms with something that would maximize the opening space. James expertly walked us through the options with cost and wall modification comparisons. In addition, the header above the current door was swelling and pinning the door, and James evaluated the issue, likely water seeping down from an unflashed deck, and provided peace of mind his guys could fix it on site during installation. Quality of Work: Frankly, 75-80% of contractors fail here for three primary reasons: a horrible handoff from the product specialist to the onsite project foreman, project foreman and workers making assumptions about details vice asking the customer, and lack of quality detailed work. The foreman excelled in these areas ensuring we were on the same page for various details such as casing, caulking, and external trim. In addition, he completely replaced the rotted wood structure above and along the sides of the door and added customer-provided insulation where there were gaps. To keep the project on track, they brought in another expert worker and management arrived to ensure the quality of work was high. The end product was beautiful. Pricing: Price was the best of three highly ranked Angie’s List companies. Zen Windows’ expertise, willingness to explain the details of the project, timely communication, and excellent work took the hassle out of this project."

"They were so easy to work with and extremely accommodating! We love our windows , front door and sliders. Price was right compared to others. Highly recommend."

"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"Quick service and very professional!"

"They are there to satisfy the customer when doing work. They are great at returning calls and are very attentive."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"Extremely well from beginning to end. The written estimate (one of 3) was provided by David Rohrer on 11/25/19 a day or two after an on-time visit to determine my need, measure the windows and explain product choices as well as the process from start to end. After obtaining all 3 estimates, I chose Unicorp on 11/27/19 based on price, product (Vytex vinyl) and most importantly...past experience (Roof, Front Entry-way). The manufacturer's rep (Mike) came on 12/10/19 to measure more precisely and a mid-January 2020 installation was projected. Several calls to keep me updated were made by the installation team/manufacturer's scheduler and installation was scheduled for 01/22/20. The installation team was a 1/2-hour early (7:30am) and thereby was able to complete all the work on a sunny, mid-40 degree day with little wind as darkness closed in. The 3-man installation team team was professional, courteous and careful with both interior and exterior, landscaping, etc., and thoroughly cleaned up the premises, inside and out. The window installation also had to be timed with my home security vendor, both before and after installation and the window crew did was very careful to avoid creating problems. The windows look great, function as promised (mechanically and insulation-wise) and the +$18k was well spent. I highly recommend Unicorp for home energy services (windows, roofing, doors) and if I ever needed siding I would go with them again."

"Nova Exteriors did a fantastic job on our windows. Tom came to give us our estimate and walk us through the various products they provide. He did a great job at answering our questions and showing us what our options were without being in-your-face-buy-my-product sales guy. The team that came and installed the windows did an amazing job. They were in and out in half a day. We had five double hung windows installed and one massive picture window. They were courteous, on time, and cleaned up inside and outside when they were done."

"Excellent job in installing windows and bow window at my lovely home. It looks beautiful and we are very happy with the results. Thanks"

"If you need a door repaired, hire Dexter. He was absolutely professional from start to finish, incredibly humble, and his pricing was more than fair. He diagnosed the issue quickly and fixed it right the first time without trying to upsell me on anything unnecessary. Honest, high-quality work is hard to come by—I will definitely be calling him again if I need anything else."
