North Forty Spray Foam & Insulation installs open-cell and closed-cell spray foam for homes, attics, rural properties, shops, metal buildings, barndominiums, and commercial buildings in Gainesville and the surrounding North Texas area.
Gainesville-area properties often sit on larger parcels with a mix of structures — a house, a shop, a barn or outbuilding. Each of those buildings has its own envelope, its own moisture considerations, and its own answer to the question of what insulation makes sense.
North Forty is a service-area contractor. We travel to your property for the evaluation — send your location to confirm coverage.
Yes. Gainesville is one of the communities we serve across North Texas. Here's what that actually means for your project.
North Forty is a service-area contractor, not a business located in Gainesville. We travel to your property to evaluate the building and discuss options in person.
Send your address and a few project details. We'll confirm we cover your location before anything else, so you're not left wondering.
We provide free estimates for residential and commercial projects in the Gainesville area, based on your actual building — not a square footage guess over the phone.
Properties in the Gainesville area often include more than one building — a home plus a shop, a barn, or an outbuilding. That's fine. Each structure gets evaluated on its own terms, because a steel shop and a framed house don't raise the same questions about vapor, ventilation, or where the thermal boundary should sit.
Tell us about all the buildings you're considering and we'll work through them together.
Spray foam is a fit for more than just houses. These are the structures we commonly look at — follow any of them for the technical detail.
Walls, attics, and other assemblies in existing homes and new builds, matched to how the house is framed and used.
Attic floor or roofline work, with air sealing considered alongside the insulation — the two usually go together.
Steel structures where condensation and temperature swings are common concerns, and where gaps around framing matter.
Mixed-use steel structures combining living space with shop or storage — a different set of decisions than a conventional home.
Barns, outbuildings, and other rural structures, where the envelope, ventilation, and moisture management all shape what makes sense.
Offices, warehouses, and retail spaces, coordinated with builders and property managers around your schedule.
Spray foam isn't a product you simply pick and install. Changing how a building is insulated can change how the whole building behaves — so we start by understanding the assembly, not by quoting a product.
This matters especially with rural and mixed-use properties, where buildings are often less conventional and previous work may have changed the original design.

How the walls, roof, and floor are built, and where the thermal boundary currently sits — or should sit.
Where moisture comes from and how it will be managed. No insulation product eliminates moisture — that's a building-level question.
Whether the space is currently vented, and whether sealing it would change how the building breathes.
Whether equipment and ductwork will end up inside or outside the conditioned envelope, and how that affects the system.
Any appliances that draw air from the space being insulated, which matters more than people expect.
How the space can be reached, and any local code or permit considerations that apply to your project.
Three steps, and no cost to you for the estimate itself.
Your location, the type of building (or buildings), and what you're hoping to address. A phone call or the form both work.
We look at the assembly, access, moisture considerations, and how the space is used — because those shape the recommendation.
You get pricing for your specific project along with the reasoning behind the approach we're recommending.
Whether it's a home, a shop, a barndominium, or several buildings on one parcel, we'll look at the structures and walk you through what makes sense. Free estimates for projects in Gainesville and across North Texas.
