GGD was founded as a local, family-owned business in 1988 by Peter Giglio, Sr. as a solo Technician out of his home. We grew. Providing superior customer service with values of Honesty & Integrity, our dedicated, experienced crews began additional service for Fairfax County homes in 1991. As our reputation for dependability spread, our 10 trucks & 15 employees outgrew the original Gaithersburg location in 2019 as we moved to a more spacious Rockville location. Peter’s son, Pete Giglio, Jr., succeeding his Dad, and long-time Operations Manager, Ryan Smart continue today to guide Gaithersburg & Fairfax Garage Door to satisfy the needs of DMV homeowners.

"Everything went fantastic Anthony was my technician, he was courteous, performed the job efficiently, did a great cleanup job of any materials in my garage. Explained exactly what was done and the future work that I needed to be done! I requested him to do the follow up work! The company itself is also great. They did follow ups via text and email; responded to everything quickly and were able to accommodate my schedule. I will continue to use them as a company."

Locksmiths questions, answered by experts

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

Replacing your locks isn’t always a necessary option. You can usually save money by rekeying locks instead of replacing the hardware. You should consider rekeying the locks instead of replacing them in the following scenarios:

  • You want to upgrade your existing locks.

  • You have a lock you don’t want to replace.

  • You recently bought a home and want to change the locks.

  • You lost your key.

Changing door locks is a task that most homeowners can accomplish on their own. Standard door knobs are quite straightforward, and even more advanced locks, like electronic or smart locks, generally come with instructions. That said, the process can be time-consuming, especially if you plan to replace multiple locks around the house. It’s also a task that you want to complete correctly, considering that it affects the security of your house. That’s why hiring a pro is often best when changing your door locks.

A deadbolt has a different design, construction, and security level than a regular lock. Regular locks are mostly used for interior doors around the home, like bedrooms and bathrooms, and they usually include a locking mechanism on the inside. While regular locks are easy to use and install, they provide little security. 

A deadbolt adds a layer of security and is most commonly used on exterior doors. The installation is typically more complicated, but they hold up to wear and tear.

Commercial locksmith services range from $75 to $500, depending on the job's complexity, such as key duplication, lock installation, or access control system setup.
