Is Your Prehung Door Worth Repairing?

Hinge screws stripping out of a split jamb, a slab planed until it stops sealing, a strike jamb rotted at the sill, a garage entry with no fire label: a slab swap fixes none of these. A prehung unit brings slab, mortised hinges and fresh jamb together, so replacement resets fit, seal and hardware at once, and a new opening starts with a door that closes right.

At King Locksmith And Doors Inc., we replace the whole prehung unit when the jamb, hinges or seal have failed, and install new units where no sound frame exists. Older DMV housing rarely offers a square opening, so we shim the jamb plumb instead of forcing the slab. An on-site assessment tells you which you need.

Why Choose King Locksmiths for Prehung Doors Installation

Prehung doors are our daily work, alongside lock installation, rekeying and access control, so the door we hang arrives with the hardware already right.

25 Years on Prehung Doors

Our technicians have set prehung units in 1920s rowhouses, 1970s split-levels and office suites across the DMV, so a 6-9/16 inch jamb or an out-of-square opening never slows the job. Licensed, Bonded & Insured means vetted technicians and insurance-ready paperwork; ALOA, SAVTA and local awards mean trained hands; being a Leading Door Hardware Brands Supplier means genuine JELD-WEN, Masonite and Therma-Tru units that fit the first time.

A Written Quote Before We Pull the Old Jamb

You see the number before the first casing nail comes out. Replacement quotes are written on site, installation estimates are free, and there are no hidden fees. What moves the price:

A Technician in 20 to 50 Minutes

A door that will not close is a security and weather problem tonight, not next week. Our technicians are dispatched from within the DMV, not through an out-of-area call center, so response runs 20 to 50 minutes and same-day slots are usually open. For planned installations we schedule around your remodel timeline; for a failed exterior unit we come now.
