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."

"Very fast service. I thought i knew what I wanted with my repair and was properly educated in what was needed. The cost of repairing my two broken glass doors was less than buying a replacement for just one."

"Global Home Solutions installed a wood screen door to replace an older door. Our home is 45 years old and accommodations had to be made. The technician did a good job adjusting to the situation."

"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."

"Jose came and started the job earlier than expected which was a great thing. He was fast and efficient and did a great job. I will surely keep him in mind for other issues around the house. The first picture was the issue and the second was how well it was fixed. (Sorry for the lack of cleanliness of the door lol)"

"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!"

"The owner was informative, friendly, and professional. We got what we needed including post-service touch-ups on the roof. Definitely recommend Pen Win. Would hire them again."
