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.

Tom B. — St. Maries
