About

Second-generation general contractor. Treasure Valley since 1986.

We build for homeowners in Boise and the surrounding cities, from major remodels and additions to custom homes, plus some select commercial work.

We started in 1986. We’re a second-generation family company and we’re veteran-owned. Idaho contractor registration RCE-5899.

People call us when a project needs a general contractor: someone to plan the work, coordinate the trades, and see it all the way through construction. Some of those projects have been over $1 million.

Every project starts with a conversation about your house and what you want to do. If it’s a good match, we define the work in preconstruction, then write a proposal and a contract. Construction follows that plan.

Process

Planning before construction.

A big addition or remodel goes better with a plan. Here's how we get from the first call to the final walkthrough.

  1. 01

    Initial Consultation

    We talk through the house, what you want to change, and whether it's the kind of project we take on.

  2. 02

    Project Qualification

    We both decide whether it's a good match. A project this size is a long working relationship, so it should start with an honest read on scope and timing.

  3. 03

    Preconstruction & Planning

    We work out the drawings, selections, existing conditions, and construction plan before we commit to a price.

  4. 04

    Proposal & Contract

    You get a proposal that spells out the work. Construction starts once the contract is signed and the scope is clear.

  5. 05

    Construction

    We run the site, manage the trades, and keep you up to date while the work is underway.

  6. 06

    Completion

    We walk the finished work with you, complete the remaining items, and leave the project in order.
