Interior door installation in St. Michael, MN mostly means replacing the hollow-core doors that came with 1995–2010 homes with solid-core slabs or prehung units. JMB Builders fits slabs to existing jambs or sets new prehung doors plumb, cases them, and adjusts the hardware so every door latches. Bifold and bypass closet doors too. Priced per door. Send pictures and we reply within one business day, or we come out for a free in-home estimate.

In St. Michael, replacing hollow-core interior doors with solid-core slabs is one of the most common requests we get, usually alongside a trim upgrade. The houses are 1995–2010 two-stories and splits, which means ten to fifteen doors on a typical floor plan: bedrooms, baths, a laundry room, linen and coat closets, and a few bifolds.

Most of these homes have jambs that are still square, so many owners keep the frames and swap only the slabs. We trace the old door, cut and plane the new one to the opening, mortise the hinges and bore the lockset. Where the trim is also being replaced, a full prehung door is often less work and gets new casing on both sides in the same pass.

Split-levels have doors on four short floors, and lower-level doors near a walkout often see more humidity. A door that swells and rubs in August is usually a hinge or a jamb that has shifted, and can be fixed without replacing it. We hang doors in Albertville and Otsego too.

Free, no obligation. Every quote is written and itemized, so you can compare it line by line.

What you supply

How it is priced: per door

Quoted in writing from your photos, with a reply within one business day. What moves the number:

  • Slab swap vs. prehung, door by door
  • Solid-core, hollow-core, glass or panel style
  • How many doors are done in the same visit
  • Closet bifolds and bypass doors vs. swing doors
  • Casing replaced with the doors or left in place
  • Who supplies the doors and hardware

A photo of each door open and closed, and a list of which rooms they are on, is enough to price the job.

How long it takes

Slab swaps: several a day depending on hinge and lock prep. A whole St. Michael two-story of ten to fifteen doors: two to four days.

Situations and options

Slabs only, frames kept

Solid-core slabs fitted to your square jambs. Casing and paint stay put; the doors get quieter and heavier.

Prehung with new casing

The right choice when the trim is being upgraded at the same time. New door, jamb and casing as one unit.

Closet doors

Builder bifolds replaced with new bifolds, bypass doors, or a swing door where the closet width allows it.

Sticking-door fixes

Hinges tightened with longer screws, strikes moved, and a door planed where it rubs, without replacing it.

Interior Door Installation in St. Michael, MN: questions, answered

Can I keep my door frames and just replace the slabs?

Often, yes. If the jambs are square and not damaged, new solid-core slabs can be fitted to them, and the casing and paint stay as they are. Most St. Michael homes from the 1990s and 2000s have jambs in good shape. We confirm it from your photos or at a free in-home estimate.

How many interior doors does a typical St. Michael house have?

A 1995–2010 two-story or split usually has ten to fifteen swing doors and a few closet bifolds. Replacing them all in one visit costs less per door than doing a couple at a time. Many owners do bedrooms and baths first and closets later.

Why does my lower-level door stick in summer?

Lower levels and walkouts often run more humid in summer, and doors swell. A door that sticks usually has a loose top hinge or a shifted jamb, not a bad slab. Longer hinge screws into the framing, a moved strike or a light planing fixes most of them.

Do I need a permit to replace interior doors in St. Michael?

A door in an existing opening is a finish job. Widening a doorway or framing a new one changes the wall, and most cities require a permit for that. If your project does, we check with the City of St. Michael building department and pull it.

What does interior door installation cost in St. Michael?

Doors are priced per door. The total depends on slab or prehung, the door type, how many go in at once, closet doors, casing, and who supplies the doors. Send photos of each door and we reply within one business day.

Can you paint the new doors?

Yes, as its own line on the quote. Most solid-core doors come primed. Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.
