We are HD Drywall, a family-run drywall and spray foam insulation contractor working across Boise and the wider Treasure Valley. Grant, Logan, and our crew handle the full arc of a job — hanging and finishing board, sealing an attic with closed-cell foam, patching water damage, or insulating a new commercial shell — and we run each one the way we would want it run in our own home. That means clean sequencing, honest timelines, and a finish that still looks right long after the drywall dust settles.
Most calls we take fall into one of two buckets: someone building or remodeling who needs the whole envelope done correctly, or a homeowner staring at a cracked seam, a sagging ceiling, or a room that never holds heat. We handle both, and we will tell you plainly when a repair makes more sense than a tear-out.
The first question on almost any spray foam insulation job is which foam to use. The two behave differently, and the right pick depends on where it is going and what problem you are solving.
| Open-Cell Foam | Closed-Cell Foam | |
|---|---|---|
| Density (approx.) | ~0.5 lb/ft³ | ~2.0 lb/ft³ |
| R-value per inch | R-3.5 to R-3.8 | R-6 to R-7 |
| Air seal | Yes | Yes |
| Vapor / moisture barrier | No | Yes (acts as a vapor retarder) |
| Adds structural rigidity | No | Yes |
| Where we use it | Interior walls, sound dampening, attics with room to fill | Crawl spaces, rim joists, roof decks, below-grade and exterior |
| Relative cost | Lower | Higher |
For most Boise attics with depth to work with, open-cell foam gives a strong air seal at a lower cost. In a crawl space or on a roof deck, where moisture control and rigidity matter, we lean toward closed-cell foam.
Not every drywall problem needs new board. This is the logic our estimators walk through on a site visit:
Boise-area homes take a beating from the swing between hot, dry summers and cold high-desert nights. A house that is well-sealed holds temperature instead of fighting the HVAC all day. On new construction around Meridian, Eagle, and Nampa, we see how much a properly sealed envelope changes that first energy bill. On older homes closer to downtown Boise, adding foam to an unfinished attic or crawl space is often the single highest-return upgrade an owner can make before winter.
It depends on the square footage, the foam type, and the thickness, so an honest number starts with a walk-through. Closed-cell costs more per board foot than open-cell but delivers a higher R-value in less space. We give free, itemized estimates — and we break down the cost factors here if you want to understand the math first.
Yes. We run residential drywall and remodels alongside commercial drywall and new-construction projects for builders and general contractors across the valley.
For a standard room, hang to paint-ready is typically a few days once we account for mud and dry time between coats. We do not rush a finish — proper drying between coats is what prevents the cracks and telegraphing that show up months later.
