"I highly recommend Clifton Contracting. The owner and all his employees are great to work with and did an excellent job installing my egress window. They even worked with me to take care of some other home to-do's on the fly. I would happily use them again."

"I cannot say enough good things about FCB. Max bends over backwards to make sure the customer is completely satisfied. I’ve never had a more responsive and conscientious contractor. We had FCB replace all of our windows in 2022. We were so impressed by the quality work and price that we called them again to replace our storm door, front door, sidelights and shutters. Great experience. Highly recommend!"

"I was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."

"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."

"Their Handyman Nestor Ramirez came my house within two hours after I contacted Chapin Handyman LLC; and it took him less than 30 minutes to locate and clear away the obstructions preventing my upper window from closing completely."

"The Premier Windows and Glass has provided an excellent service for me! A frame of one of the windows in my condo was broken, and I looked for a company that would fix it and prolong the life of the window. So, I was very happy to discover The Premier Windows and Glass. Their technician was very polite, professional, and knowledgeable. Not only did he do a quality job on fixing the frame, but he also explained to me what needs to be done to prevent the window from breaking down again and avoid paying a lot of money for its replacement. In addition, the manager and technician responded to my service request in a prompt manner. The problem was solved on the day when I called the company. Last but not least, the company offers competitive service rates and does not push people to spend more money than is absolutely necessary. I would strongly recommend this company to anyone who needs to have a window fixed or replaced."

"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."

Window Door Contractors questions, answered by experts

In Gaithersburg, you’ll find several options for screen repair and replacement. Full-service window contractors handle both glass and screens, while local specialists focus on custom screen fabrication and re-screening. Handyman services are ideal for minor repairs or multiple small projects. Mobile screen repair providers offer on-site service, which is convenient for busy homeowners. Some hardware stores also connect residents with experienced installers for window screen replacement.

Helpful?

In Gaithersburg, homes with unique architectural features—such as arched or oversized windows, sunrooms, or multi-level designs—often require custom window screen replacement. Older properties may have frames that are no longer standard sizes, making sourcing materials more complex. Dense shrubbery, steep driveways, or limited side access can also make reaching certain windows challenging, so it’s wise to assess these factors before hiring a screen repair contractor.

Helpful?

In Gaithersburg, the combination of humid summers and cold winters can significantly affect window screen repair. High humidity often causes screens to loosen or sag, while winter’s freezing temperatures can make mesh brittle and prone to cracking. Spring storms frequently result in torn screens from wind-blown debris. For lasting results, schedule repairs after pollen season in late spring or early fall, when temperatures are milder and humidity is lower.

Helpful?

In Gaithersburg, homeowners should check for HOA guidelines regarding screen color and style, especially in newer developments. Extensive porch or patio screen projects may require permits, and homes in historic neighborhoods could face additional restrictions. High pollen and insect activity in spring can increase demand for repairs, so booking early is wise. Consider tree coverage, which can lead to more frequent screen damage, and plan appointments around local school or commuter traffic for convenience.

Helpful?

In Gaithersburg, be wary of screen repair contractors who provide vague or verbal-only estimates, push for immediate decisions, or request large deposits upfront. Watch for quotes that seem unusually low, as this may indicate subpar materials or rushed work. Reliable professionals will measure your windows, specify the type of screen mesh used, and offer clear warranties. Always ask for local references and written documentation before agreeing to any work.
