Common Scenarios

Rental Turnover — Locks & Doors

Between tenants, landlords need locks re-keyed or replaced, doors adjusted after years of use, and hardware refreshed. Build & Fortify handles all of this as part of a turnover punch list — often alongside drywall patching, plumbing fixes, and other move-out repairs.

New Home Move-In

Just bought a house and the previous owners left you with doors that scrape, windows that won't stay open, and locks you don't trust? One visit from Build & Fortify gets everything adjusted, replaced, and working right.

Childproofing & Safety

Door stops, soft-close hinges, window locks, and safety hardware — installed properly so they actually hold up to daily use.

Frequently Asked Questions

How much does lock replacement cost?

Basic deadbolt + knobset replacement runs $75-$150 for labor (hardware not included). Re-keying existing locks is less — typically $50-$100. Keypad lock installation runs $100-$175 depending on the lock and door prep needed.

Can you install a new door?

Pre-hung interior doors (where the door comes already mounted in its frame) — yes. Exterior door replacement or custom door framing is contractor territory. Chad will let you know honestly if your job needs a specialist.

My sliding door is really hard to open. Can you fix that?

Usually, yes. Most sliding door issues are worn rollers, dirty tracks, or misaligned frames. Roller replacement and track cleaning typically solve the problem. If the frame itself is warped or the door needs full replacement, that's a different scope — and we'll tell you upfront.
