Interior Door Installation

Few things date a house faster than its interior doors. Hollow flat panels from the 1980s, brass knobs in three different styles collected over the decades, hinges painted over so many times they crackle when they move. And few things modernize a hallway faster than swapping them, because unlike paint, a door gets touched fifty times a day. We install interior doors across Lancaster County and Chester County as a standalone job: one door that never latched right, or every door in the house in a single scheduled pass. A crisp two panel door with a matte black lever changes how a hallway feels more than any color on the walls, and it is one of the few upgrades you interact with every single day you live there.

There are two ways to replace a door, and picking the wrong one wastes money. A prehung door arrives already hinged in its own jamb, and the old jamb and casing come out with it. That is the answer when the frame is beat up, out of square or chewed by the dog. A slab replacement keeps your existing jamb: we mortise hinges into the new door to match the old locations, bore for the latch, and plane the edges to fit the opening the house actually has. That is the answer when the jambs and trim are in good shape, and it saves real money on every door. Either way the standard is the same: hung plumb so the door stays wherever you leave it, even reveals on all three sides, a long screw through the top hinge into the stud, and a latch that clicks shut with one finger. A door you have to lift and shove is not installed, it is parked.

Most of our door work comes as whole house packages, like this [whole house door replacement in West Chester](/projects/interior-door-replacement-west-chester-pa), where every door, hinge and lever got replaced in one pass. Batching is where the price gets friendly: setup, delivery and disposal spread across ten or fifteen doors instead of one, which pulls the per door cost toward the low end of the range. We also unify the hardware in the same trip, one finish and one lever style throughout, privacy locks where bedrooms and bathrooms need them, so the house stops looking like a hardware store sampler. And the honest advice we give at estimates: if your doors are solid, latch cleanly and you simply hate the color, paint them. A gallon of enamel and a patient weekend beats thousands of dollars of new slabs, and we will say exactly that when it is true. Across Lancaster County and Chester County, most prehung installs land at $350 to $600 per door.
