Best door pros near Potomac, MD

"Bottom Line: If customer service, especially years after installation, matters to you, then you NEED to work with this company. In 2018, we had new Provia external doors installed for our entryway and garage. After 8 years, the door sweeps were beginning to wear, and unfortunately, the original installer had retired his business. I was uncertain who exactly should handle the replacement in this case. As a long shot, I contacted Zen Windows who installed a Provia patio door for us in 2025. They sent out a technician who honored Provia’s warranty on our 2018 doors, replaced the sweeps, and realigned the doors as well. In a world of truly lackluster customer support, Zen Windows stands out as truly great. You will not find a better company."

"Jeremiah was a professional! He was on time, knowledgeable, and very polite and friendly. He, actually, did the whole job on-site---custom cut and replaced the glass in less than one hour. Thanks to him and to William, who helped with scheduling and invoicing. I would recommend Boston Window and Door Co. to anyone."

"Mr. Cooper was incredibly responsive to my request for a patio screen door repair. He was friendly, knowledgeable, and kept us informed throughout the process. The repair he performed on our screen door was EXCEPTIONAL and was promptly completed. I highly recommend him to anyone seeking a reliable and experienced window/door professional. I?ll definitely reach out to him again if I ever need another project."

"Door Repair - They did excellent work--fast and efficient. They found a solution where I thought there was none."

"We have had NovaExteriors replace all our gutters, windows, sliding doors and front door over the last several years from the contractor grade products that the town house was built with. We have been very pleased with everything. They installed our steel front door about 10 years ago and we started to have issues with the deadbolt not aligning with the door jam and the rubber sweep wearing out over time. I contacted NovaExteriors, made my appointment and they arrived right on time and performed the needed maintenance that was required. The door is back to being perfect. Once again, we were very pleased with NovaExteriors, their prompt arrival and the quality of work. You can't go wrong with NovaExteriors."

"Dex came out and fixed a bad storm door install. He showed up within the window he provided and gave an ETA as well. Very friendly and very reasonable on cost. I would recommend using him for any window or door needs."

"This wasn’t the first time I used Vazquez & Son. In 2014, they expanded my closet and built custom doors for it. Luis and his team are alway nice, attentive to detail, and leave the work area clean. So, when my bathroom ceiling was torn up to repair a leak I called him immediately to repair and get my bathroom back in order. In fact I had them repaint the whole thing and it looks great. I’m writing this review a year later because once again I have an emergency repair need (broken bay window) and once again Vazquez & Son are to the rescue! I had been traveling out of the country and a guest using my place broke the window. From the airport, on a Sunday morning, I texted Luis a picture of the window and he responded within 10 mins. It is great to have a reliable responsive handyman/construction service provider when you need one. Not all my projects are big money, but it’s my home (1 bedroom apartment) and having things done right matters to me. Vazquez & Sons treats my projects like professionals and never make me feel like small potatoes. I’m a loyal customer, and plan to be, as long as Vazquez & Son is in business."

"They installed a new patio door handle for me - it wasn’t easy since I didn’t buy the right direction handle haha but they made some adjustments. Fair pricing, flexible scheduling. Would hire again!"

"All if my interactions with Pen Win Windows and Doors, LLC has been extremely pleasant. I was extremely with the time and effort they took to inspect my roof as well as the time they took to address all y questions and concerns."

"It's always a relief when you find a contractor who cares about the quality of their work. That is Mr. Leal. I hired him to rehang our exterior french doors that were poorly installed. It can be very difficult to find help for for small jobs, but Mr. Leal agreed. Needless to say, the doors now function perfectly. I was impressed for following reasons. His team was very communicative. My initial call was returned within an hour or two and he was scheduled to see me the next day. He and his colleague took care of my home. Not only did they fix the doors, but they were obviously very careful when doing so. They even vacuumed while sanding the doors. No trace was left of their work except for the perfectly swinging doors. Honestly, I think care for another's home is as important as one's ability to do the work. My strong impression is Mr. Leal cares that his work is well done. Hire him."
