Quick answer

All four are licensed in Washington and rated A+ by the BBB. Neil Kelly has the longest record (since 1947, 2,381 GuildQuality reviews). Mountainwood (NAHB's 2025 Remodeler of the Year) and Lamont Bros (two 2026 NARI national awards) have the strongest award records. JDI is the only one based in Clark County, has the lowest published starting prices, takes smaller jobs such as a shower remodel, and puts a 5-year warranty in writing.

Who fits which project

Choose Neil Kelly for a large, high-budget remodel where a 79-year track record and a structured paid design phase matter more than speed. Plan on 30 to 44 weeks.
Choose Mountainwood for a whole-house remodel or custom home with a large budget, where a national award record is worth the price. Ask for the warranty terms in writing; none are published.
Choose Lamont Bros for a larger, design-heavy project of $75,000 and up, especially on the Oregon side, with a fixed-price contract.
Choose JDI for a kitchen, bath, ADU or addition in Clark County, from a $15,000 shower to a whole-home remodel, where a local team, a written 5-year warranty and a shorter build matter. We are younger and smaller than the other three, with fewer reviews and no national awards.

Questions to ask any of them

What does the written warranty cover, for how long, and what does it exclude? Does it cover subcontracted trades?
What does design cost before I sign a build contract, and is it credited to the project?
Is the contract fixed-price, or does it use allowances?
Who will be on site each day, and who is my single point of contact?
Can I talk to two clients who finished a similar project in the last year?
