"I am still waiting for the return of my deposit as it has been a week since I put this review on hold after putting in the notice that day 24 June of cancellation by email and next day mail. As I have said before I am a disabled Vet, Senior citizen with health problems. I have copies of the emails that I sent on the days of 06/24/2023 and by next day Mail on the 27th notarized copies of the cancellation. Tried calling but went to voice mail. No work has been done so a rating cannot be done on the work, only the price. This job was way overpriced and never got the chance to compare. The salesman was a good person but I have my family doing it for thousands less."

"Had windows and doors installed by this company. The window installation went great. The bad news is that they do not seem competent at installing door hardware. My door has not latched properly since they made some unwanted modifications to the hardware (it worked perfectly before they started modifying it).have had them out three separate times to fix the issue they caused with the door latch and lock. Every “fix” they do seems to make the problem worse. I would steer clear of this company for door installations."

Security Doors questions, answered by experts

Completing a door service project in Gaithersburg offers immediate benefits like improved home security, better insulation, and enhanced curb appeal. Over time, you’ll notice increased property value, lower energy bills, and less frequent maintenance. High-quality doors can withstand local weather, reduce noise, and may even help with insurance premiums. These upgrades are especially attractive to buyers in Gaithersburg’s active real estate market.

Helpful?

For minor door issues in Gaithersburg, you can safely tighten loose hinges, lubricate hardware, and replace worn weather stripping to improve energy efficiency. If your door sticks, gently adjust the strike plate or sand rough edges. Always use proper tools and enlist help for heavy doors. If your door has electrical components or security features, or if structural changes are needed, contact a professional for safety.

Helpful?

In Gaithersburg, homeowners are embracing smart entry systems, including integrated video doorbells and keyless locks for added security and convenience. Energy-efficient fiberglass and steel doors are favored for their durability and insulation. Many opt for glass inserts, sidelights, and transoms to maximize natural light. Modern craftsman styles and bold, dark finishes are trending, while reinforced frames and storm doors help protect against Maryland’s seasonal weather.

Helpful?

In Gaithersburg, door maintenance should include seasonal inspections for weather stripping, checking for warping or swelling during humid summers, and cleaning hardware to prevent rust. Lubricate hinges every few months and touch up paint or finish as needed to protect against moisture and UV damage. Annual professional inspections help catch issues early, ensuring your door remains energy efficient and secure throughout the year.

Helpful?

In Gaithersburg, you’ll find general door installers, locksmiths for security upgrades, and specialists in smart home integration. Some contractors focus on historic homes and can match unique architectural styles common in older Gaithersburg neighborhoods. Commercial door experts handle business properties, while handypersons tackle basic repairs. Always check for local experience, proper insurance, and references from recent projects in your area before hiring.
