Door Installation & Replacement in Brooklyn in Brooklyn & NYC

Replacing a door in a hundred-year-old Brooklyn building is rarely a drop-in job. Openings are out of square, frames are original, and the new slab has to be fitted to the reality of the wall, not a catalog spec. We measure the opening, account for how the building has settled, and hang the door so it swings clean, seals against the weather, and locks without a fight.

For homes we install and replace brownstone and apartment entry doors, interior doors, and back doors, and we make sure the lock prep, hinges, and threshold all line up. For commercial clients we handle storefront entrances, back-of-house doors on retail corridors, and heavier fire-rated openings where the hardware and self-closing behavior have to meet code. When a door is going in as a security upgrade, we can pair it with a reinforced frame and high-security lock hardware in the same visit.

Because we are a locksmith and door shop under one roof, the door and the lock get installed and keyed together, so you are not coordinating two trades. We work across all five boroughs and finish the job so the door is fully functional before we leave, latch tested, closer set, and keys in hand.
