“We build every exterior the way we’d build our own — to spec, and to last.”
Serving Spokane for 9+ Years
Domex Construction is a family-owned exterior remodeling contractor. We install James Hardie and LP SmartSide siding, energy-efficient replacement windows, and custom decks, and we take on kitchen, bathroom, and whole-home remodels — all handled in-house by crews with 32 years of combined experience.
From the first job, the standard hasn’t changed: build exteriors that look right, perform flawlessly, and stand up to decades of Northwest weather. It’s the reason so many Spokane and Coeur d’Alene homeowners keep calling us back — and why so much of our work comes by referral.
Built to Last
New siding is a decades-long investment. As a James Hardie Preferred contractor, we install to exact spec — and when you need a repair or a section replaced years from now, the same local team will still be here to handle it.
From First Walk-Through to Final Walkthrough
Every project follows the same proven process — no guesswork, no surprises.
Free On-Site Consultation
We walk your property, listen to what you want to accomplish, and build a plan that fits your budget and the way your home actually lives.
Written, Itemized Specs
Product, color, trim, flashing, and rot-contingency terms on paper before any work starts. No surprises on the invoice.
In-House Installation
Our own crews handle the tear-off, prep, flashing, and finish work — installed to manufacturer spec and dialed in before handover.
Ongoing Support
We don't disappear after the install. A 12-month workmanship warranty, and a team that still picks up the phone years later.
Domex Construction is a family-owned exterior remodeling contractor serving Spokane, Washington and Coeur d’Alene, Idaho. We install James Hardie and LP SmartSide siding, replacement windows, and custom decks, and we take on full home remodels — licensed in both states and running every job in-house with our own crews.
Our Story
What started as a siding specialist has grown into one of the Inland Northwest’s trusted names for siding, windows, and decks. The work hasn’t changed in principle: build exteriors that look right, work reliably, and hold up to decades of freeze-thaw winters and hot, dry summers. That’s why homeowners across Spokane and North Idaho keep calling us back for the next project.
What We Do
We install and repair every kind of exterior: James Hardie fiber cement, LP SmartSide engineered wood, and vinyl siding; energy-efficient replacement windows; and custom composite and cedar decks. Inside, we handle kitchen and bathroom remodels, home additions, and whole-home transformations. Whether it’s a full re-side or a single storm repair, we take it from consultation to final walkthrough with our own crews — no subcontractors handed the job.
Built for the Inland Northwest
Siding only performs the way it should when it’s installed to spec, and our region is unforgiving — freeze-thaw cycling on fiber-cement joints, hail exposure, wildfire-smoke season, and 100°F summers against single-digit winters. As a James Hardie Preferred contractor, our crews are factory-trained to flash, fasten, and finish to the manufacturer’s standard, so the wall holds up long after the job is done.
