Why St. Maries Chooses Vandenberg for Room Additions

Ryan Vandenberg founded this company specifically because the industry had let quantity take over at the expense of craftsmanship. Every project we take, we finish right.

Upfront, Honest Pricing

We’re straightforward about what things cost and we never overbid for our own gain. Our quote is our quote.

Finish Carpentry Roots

Ryan started as a finish carpenter. That precision shows in every trim detail, built-in, and cabinet installation we deliver.

Subcontractors We Stand Behind

We hold every subcontractor to the same standard we hold ourselves. If it doesn’t meet our bar, it doesn’t leave our job site.

Owner Involvement Start to Finish

Ryan is involved from your initial inquiry through project completion. You’re not handed off to a project manager who’s never held a tape measure.

Yes. All room additions require building permits in Idaho, plus mechanical, electrical, and plumbing permits as applicable. Vandenberg Construction manages the permitting process and coordinates all required inspections.

A standard room addition (master suite or family room addition) typically takes 3–6 months from permit approval through completion. Timeline depends on scope, finish level, and the exterior construction window. Projects that start in spring and have exterior work wrapped by fall typically move fastest.

Yes. Vertical additions (second-story builds) are an option when the lot doesn’t allow outward expansion, or when maintaining yard space is a priority.

What Clients Say About Vandenberg Construction

Ryan Vandenberg is personally involved in every project from first call to final walkthrough. Here's what clients across Northern Idaho say.

★★★★★

Ryan and his crew built our deck and covered porch last summer. The 3D rendering process was something I had never seen from a local contractor before—we knew exactly what we were getting before they started. The craftsmanship is outstanding.

Mike D. — St. Maries

★★★★★

Full kitchen remodel, and it came out better than the 3D rendering. Pricing was upfront and honest—no surprises on the final invoice. Vandenberg is the real deal.

Sarah T. — Coeur d'Alene

★★★★★

Vandenberg built our lakefront deck and screened porch. The finish carpentry on the railing detail work is exactly what I wanted. These guys hold their subcontractors to a high standard too—everyone on site was professional.

James W. — Harrison

★★★★★

We did a full master bathroom remodel. Ryan walked us through every decision and the tile work is flawless. This is what quality-over-quantity actually looks like in practice.

Linda P. — Kellogg

★★★★★

Room addition on our home—master suite with a walk-in closet. The drywall finish and trim work are seamless with the existing house. You can’t tell where the old house ends and the addition starts.
