What's wrong with most old doors
Doors take more abuse than anything else in the house. After a few decades, it shows.
-
Doors that stick or won't latch
The house settles, the frame racks out of square, and the door rubs at the top or misses the strike plate.
We set new frames plumb and square with shims, so the gap around the door is even.
-
Thin, hollow-sounding doors
Builder hollow-core doors dent easily and let every sound through.
Solid-core doors feel heavier, block more sound and hold up better in kids' rooms.
-
Big gaps under the door
Doors cut short for old carpet leave a wide gap once hard floors go in.
We size new doors for the floor that's there now, or trim and rehang the ones you keep.
-
Mismatched doors room to room
One six-panel, one flat, one bifold from a different decade.
We match style, hardware finish and trim through the whole hallway.
How we replace your doors
One crew handles the doors, trim and touch-up. You get a written price and a start date before we order anything.
-
Measure every opening
Width, height, wall thickness and which way each door swings. Old houses rarely have two openings exactly alike.
-
Pick doors and hardware
Style, solid or hollow core, and knob or lever finish. Everything goes into an itemized price.
-
Remove and set
Old door and frame come out. The new frame goes in plumb, shimmed tight and nailed to the framing.
-
Trim and hardware
New casing on both sides, hinges tightened with long screws into the framing, latch and strike lined up.
-
Adjust and walk through
We swing every door with you, adjust anything that rubs, clean up and haul away the old doors.

Interior doors for Long Island homes
We handle interior door installation on Long Island from start to finish: the door, the frame, the trim and the hardware. A new set of doors is one of the quickest ways to make a house feel updated. You touch them every day, and a door that rubs, rattles or won’t stay latched gets old fast.
Most high ranches, capes and split-levels around Medford and Lake Grove were built with light hollow-core doors. Decades later, the frames have shifted, the hinges are loose, and the doors don’t match the rest of the house anymore. Replacing them hallway by hallway, with matching trim and hardware, makes the whole floor look like it belongs together.
Why a door has to be hung right
A door is only as good as the frame it hangs in. If the frame is out of plumb, which means not straight up and down, the door will swing open or closed on its own, rub at one corner, or leave an uneven gap. We shim the frame at the hinges and the latch, check it with a level in both directions, and set long screws through the top hinge into the framing so it doesn’t sag later. Then we test the latch and adjust the strike plate so the door closes with a light push.
Closet doors that work
Closet doors cause more complaints than any other door in the house. Bifolds jump off their track, sliding doors grind and come loose at the bottom, and swinging doors hit the bed or the dresser. We look at how deep the closet is, what sits in front of it, and how you use it before we recommend a type. Then we set the track level and anchor it to the framing, so the doors roll or fold the way they should.
Doors and floors
New flooring and new doors go together. If you’re putting in vinyl plank or tile, the floor height changes, and doors that cleared carpet may now drag. When we do both, we plan the door height around the finished floor so the gap underneath is even from room to room.
Before we measure
- Count the doors you want replaced, including closets
- Think about hardware: knobs or levers, and a finish like black, brushed nickel or brass
- Note any doors that swing into each other or into a light switch, so we can fix the swing
- Let us know if new floors or new trim are part of the plan
If you only have a door or two that sticks and nothing else on the list, that can be a smaller visit through our handyman service. Photos of your current doors and hardware help us bring the right samples.
Interior door questions
How much does it cost to replace interior doors?
It depends on how many doors, pre-hung or slab, solid or hollow core, the style, the hardware, and whether the trim is being replaced too. Odd sizes in older houses can add to it. We measure every opening and give you a written, itemized price before work starts.
Should I get pre-hung doors or just new slabs?
If your frames are straight and in good shape, a slab can work and keeps your existing trim. If the frames are out of square or damaged, pre-hung doors fix the problem at the source. We check each opening and tell you honestly which makes sense.
Can you keep my existing trim?
Sometimes. Trim can often be pulled off carefully and reused with a pre-hung door, but older trim can split coming off. If you're replacing a lot of doors, many people take the chance to put in new casing at the same time.
My doors hit the new floor. Can you fix that?
Yes. We can take a door off, cut it down cleanly, seal the cut edge and rehang it. If a door has to be cut a lot, a new door is sometimes the better choice.
Can you put in a pocket door where there's a swinging door now?
Often, but it means opening the wall, reframing it for the pocket, then sheetrock, patching and paint. We do all of that, so it's one job. Walls with pipes or wires in the way may need a different plan.
How long does door replacement take?
That depends on how many doors, whether frames and trim are being replaced, and whether any doors are special order. The written price you get from us includes a start date and how long the job will take.
