Is Your Home Door Costing You Comfort or Security?

Old doors leak air, and gaps let in cold, heat, and bugs. The U.S. Department of Energy notes that insulated steel and fiberglass doors save more energy than most wood doors. A warped frame or loose strike plate can also make a lock easy to force. If you see daylight around the edges, feel a draft, or fight with the deadbolt, call us. We will inspect the door and give you honest options and a clear price.

Frequently Asked Questions

Have questions about your home’s doors? Here are clear answers to what DMV homeowners ask us most about door installation, replacement, and repair. Still unsure? Give us a call and we will gladly help.
Should I repair or replace my front door?
Repair makes sense when the door slab is solid and the problem is small, like a sagging hinge, worn weatherstripping, or a lock that won’t latch. Replace the door when the slab is cracked, rotted, or warped, or when the frame is damaged. We inspect the door first and tell you which option saves you more over time.

Most single door replacements take a few hours. A prehung door goes in faster because it comes already set in its own frame. Patio doors, French doors, and custom sizes can take longer. We give you a time estimate before work begins, and we clean up when we finish.

Fiberglass is a strong choice for our humid summers and cold winters. It resists dents, rot, and warping, and it insulates well. Steel offers great security at a lower price. Wood looks classic but needs more upkeep. We help you choose based on your budget, style, and how much sun and rain the door gets.

Yes. Because we are locksmiths too, we install deadbolts, handlesets, smart locks, and reinforced strike plates when we hang your door. We can also rekey the new locks to match your current keys, so one key opens every door in your home.
