Mountain Home sits southeast of Boise on the high desert plain, with Mountain Home Air Force Base shaping a good deal of the local housing market. The building environment is different from the Treasure Valley — drier, more exposed, and with real wind to account for.
We work throughout Mountain Home on remodeling, additions, custom construction, shops, and detached garages, on both city lots and the surrounding acreage.

What we find in Mountain Home homes
Mountain Home’s housing is heavily weighted toward post-war and later construction, with a significant volume of 1950s through 1980s homes tied to the air base and a steady stream of newer subdivision building. The older stock needs the usual systems attention — panel and circuit upgrades, plumbing, insulation, and windows — and benefits substantially from envelope work given how exposed the site conditions are. Acreage properties outside town are typically on well and septic with existing outbuildings of varying quality.
Permitting and planning in Mountain Home
The City of Mountain Home permits within city limits and Elmore County handles rural parcels. The exposure here is a genuine design factor: wind loading, driving dust, and a wide daily temperature swing all argue for careful attention to flashing, sealing, roofing fastening, and insulation continuity. Acreage in this area often means a deep well and a longer power service run than people expect, and both should be established before a house plan is settled. Snow load rises quickly as you move toward the Danskin and Bennett Mountains.

Learn moreBuilding in Mountain Home: common questions
Do you take projects in Mountain Home?
Yes — Mountain Home is within our service area and we work there regularly on both remodels and new construction.
Does the wind out here change how you build?
It should. Roofing fastening patterns, flashing detail, siding attachment, and sealing all deserve more attention on an exposed high-desert site than on a sheltered valley lot. Skimping there is what produces callbacks after the first serious wind event.
What about building on desert acreage?
Expect a deep well, septic with district health approval, a potentially long power service run, and driveway and access work. Those items can represent a meaningful share of the total, so we price them at the start.

“The finished work was excellent, delivered on time, and inside our budget. What more is there to ask?”
Our experience with GW Construction was outstanding from beginning to end. They were recommended to us by a real estate agent we trusted, who was helping us plan a remodel of a home we had just purchased. Past contractors had been hit or miss for us, so committing to a renovation north of $70,000 made us genuinely nervous. That changed at the first meeting. Derek listened carefully to what we wanted the remodel to accomplish and then carried the plan out faithfully. Just as valuable, he offered real insight where he saw a way to improve on our thinking, and told us plainly when an idea of ours was not economically sensible or carried a downside we had not considered. He was straightforward, transparent, and respectful throughout. Communication was excellent — calls, emails, and texts were returned promptly. He even introduced us to each of the subcontractors so we could build a relationship with them directly. Most importantly, the finished work was excellent, delivered on time, and inside our budget. What more is there to ask? Highly recommended.
Jack and Sue Serrino“He has completed more than 25 projects for my clients over the years, and I intend to keep sending them his way.”
Derek is far and away the best contractor I have worked with, and his ability to listen to my clients and respond to what they actually need has exceeded anything I expected. Being classically trained and professionally educated shows in the work. His grasp of both the practical and the possible means he handles small and large-scale jobs equally well, and there is genuinely nothing I would hesitate to refer to him. He has completed more than 25 projects for my clients over the years, and I intend to keep sending them his way.
