- Priced per door
- Slabs fitted to original jambs
- Solid-core swaps for builder doors
Older homes near Elk River's downtown often have doors that are not a stock size today, in jambs that have moved with the house for decades. Replacing the whole unit means losing the original casing. Fitting a new slab to the old jamb keeps it: we trace the opening onto the slab, cut and plane it, mortise the hinges where the old ones were and bore for the lockset.
In the subdivisions built north and east of town in the 1990s and 2000s, the doors are hollow-core and the jambs are usually square. Owners there tend to replace the whole set, often with solid-core doors in bedrooms and baths, which block more sound and feel solid in the hand. Prehung units are the quick route when the casing is being replaced anyway.
Interior French doors between a living room and an office or den are the other frequent ask. They need a jamb that is square, or the two doors never meet evenly in the middle.

Interior Door Installation in Elk River, MN: questions, answered
Can you fit a new door into an old jamb in an older Elk River house?
Yes. We trace the old opening onto the new slab, cut and plane it to an even gap, and mortise the hinges to line up with the existing hinge pockets where we can. The original jamb and casing stay in place. Stain-grade slabs also need the color matched to the old trim.
My old door is an odd size. Can I still get a new one?
Usually. A slab can be cut down from the next stock size because it has solid rails and stiles around the edge, within limits. A door far smaller than any stock size may need a slab made to size. A photo with a tape across the old door tells us which.
Is it worth replacing hollow-core doors in a 2000s house?
For bedrooms, bathrooms and an office, most people notice the difference in sound and feel right away. Closets can stay hollow-core to keep the cost down. Doing the whole set at once keeps the style matched and lowers the per-door rate.
Can you install interior French doors in Elk River?
Yes, as a prehung pair or in an existing opening that is wide enough. The opening has to be square for the doors to meet evenly, so we check it first. Widening an opening can mean a new header in a bearing wall, and that is permit work we check with the City of Elk River building department about before we start.
Do you supply the doors or do I buy them?
Either works. You can buy doors at a lumberyard or big-box store and we install them for labor only, without marking up the product. Or tell us the style and core and we put the doors and hardware on the quote. Send photos of the openings before you buy and we check sizes and handing.
Do you hang interior doors near Elk River?
Yes. We are based in Zimmerman and hang interior doors in Elk River, Otsego, Rogers and across the Twin Cities. Send photos for a reply within one business day, or book a free in-home estimate.
