Why businesses call Charleston Locksmith for door replacement

Licensed & insured, serving the Lowcountry

We're a fully licensed and insured locksmith covering Charleston, Summerville, and the surrounding communities. Every replacement is protected - no unlicensed subcontractors on your property.

Family-run Kadosh team

You work with the same local, family-run crew from estimate to final walkthrough - not a rotating cast of dispatched strangers. We answer for our own work.

Hardware-certified installers

Certified on Mul-T-Lock and Lockly systems, so the new door leaves with high-security locking hardware fitted and keyed correctly the first time.

Free, itemized estimates

We measure the opening, inspect the frame, and give you a written quote before any door is ordered. No surprise add-ons after the crew arrives.

What our commercial door replacement covers

We replace the door, the failing hardware, and the parts that cause the door to fail again - not just the slab.

Aluminum storefront doors

Bent, sagging, or racked glass storefront doors replaced with new aluminum-frame units - pivots, sweeps, and thresholds squared to the opening.

Hollow-metal & steel doors

Rusted or dented steel doors and frames swapped for new hollow-metal units at back entrances, stairwells, and service corridors.

Fire-rated door replacement

Labeled fire doors installed to match the rating of the opening, with self-closing hardware and positive latching that keeps your inspection on track.

Exit devices & panic bars

New push-bar exit devices fitted so egress doors open freely in an emergency and lock securely the rest of the day.

Door closers & hinges

Overhead and concealed closers, continuous hinges, and pivots replaced so the new door shuts flush and stops slamming.

High-security locks & access

Mul-T-Lock cylinders, Lockly keypads, and card-reader-ready hardware installed and keyed to your existing system.

How the replacement works

  1. 1

    On-site measure & free estimate

    We visit your Charleston or Summerville location, measure the opening, check the frame and hinges, and confirm any fire rating or ADA requirements.

  2. 2

    Written quote & door selection

    You get an itemized quote covering the door, frame work, hardware, and labor. We help you pick the right slab, finish, and lock package.

  3. 3

    Removal & installation

    The old door and worn hardware come out, the opening is prepped and squared, and the new door is hung, sealed, and adjusted.

  4. 4

    Testing & walkthrough

    We test latching, closing speed, egress, and keys - then walk it with you so the door is ready for business that day.

Pro tip: replace before your fire inspection, not after

In Charleston County, a fire door that won't self-close and positively latch is a common failed-inspection item. If your rated door drags, the closer leaks, or the label is painted over, replace it before the fire marshal visits - a scheduled replacement is far cheaper than an emergency fix plus a re-inspection fee.

  • Check that the fire label on the door edge is legible and intact.
  • Watch the door close fully from any open position without a push.
  • Listen for the latch to click home every time.
  • Note any daylight around the frame - a warped opening kills a door's seal.

What Lowcountry businesses say

"Our back steel door was rusted through and wouldn't lock. The Kadosh crew replaced the door and frame in one morning and re-keyed it to our other locks. Clean, fast, professional."

- Marcus T., restaurant owner, Charleston

"We failed a fire inspection over a closer that wouldn't latch. They came out, gave a free estimate, and swapped the fire-rated door plus panic bar before the re-inspection. Passed clean."

- Danielle R., property manager, Summerville

"Great work on our storefront glass door - the pivot and threshold were shot. New door opens smooth and the Mul-T-Lock they put in is solid. Straightforward pricing too."

- Kevin A., retail shop, West Ashley

Commercial door replacement FAQs

Most single-door replacements are completed in a few hours once the door is on hand. Doors that need frame work, fire-rated units, or custom hardware may take longer - we give you a timeline with your written estimate.

Yes. We install labeled fire doors matched to the rating of the opening, with self-closing and positive-latching hardware so the door meets the requirements a Charleston County fire inspector will check.

In most cases, yes. As certified Mul-T-Lock installers we can key the new door to your current master or restricted-key system, or set up a fresh high-security keyway if you're upgrading.

Yes. We come to your Charleston or Summerville property, measure the opening, inspect the frame, and give you a written, itemized estimate at no cost and no obligation.

That's exactly what our on-site inspection determines. If the slab and frame are sound, we may only need to replace the closer, hinges, or lock. If the door is warped, rusted, or racked, replacement is the reliable fix - and we'll tell you honestly which you need.
