Spokane & Coeur d’Alene’s Full-Service Exterior Remodeling Contractor
Domex Construction installs siding, windows, and custom decks for homes across the Inland Northwest. We are a family-owned company that handles the whole project in-house: the tear-off, the prep, the flashing, and the finish work, so one licensed local team is accountable from the first measurement to the final walkthrough.
What We Do
Siding Installation
James Hardie, LP SmartSide, and vinyl, installed to manufacturer spec.
James Hardie Siding
ColorPlus fiber cement from the Inland Northwest's Hardie Preferred contractor.
Window Replacement
Energy-efficient Milgard and Andersen windows built for four-season comfort.
Custom Decks
Trex, TimberTech, and cedar decks designed around how you live.
Siding Repair

Remodeling
Kitchens, bathrooms, additions, and whole-house remodels.
Residential & Whole-Home Exterior Work
Most of what we do falls into three areas. For homeowners, that means full re-sides, window packages, and custom decks. For whole-home projects, we combine siding, windows, and trim into a single scope with one schedule and one crew. And across everything, we spec factory-finished materials that stand up to Spokane’s sun-and-snow cycle.
Because our installers are in-house and our leadership stays close to the work, the specs, the install, and the warranty all come from the same team. And that team is still here years later when you need us.
