Residential Door Replacement
A worn or warped front door can let in drafts, stick in humid Maryland summers and make your home easier to break into. We replace exterior entry doors, back doors and interior doors, then fit them with properly aligned deadbolts, reinforced strike plates and hardware that matches your home. If your door was damaged in a forced entry, we can secure the opening quickly and replace the door and frame as needed. For lock-only work, see our residential locksmith services.
Commercial Door Installation
For Gaithersburg businesses, we install and replace storefront glass doors, hollow metal doors, steel back-of-house doors and interior office doors. We coordinate the door, frame, closer, exit device and locks so everything works together, and we can recommend hardware that meets NFPA 80 fire door requirements where a fire-rated opening is needed. Pair your new door with our commercial locksmith services for master keys or access control.
