Before Drywall or After Move-In, Insulation Contractors Severance, CO Work on New Builds
If your Severance house is still framed, you are in the cheapest window you will ever get for insulation. If it is already finished, the work shifts to the garage, the rim joist, and the attic. Insulation contractors Severance, CO spend most of their time on new construction, so this page is organized by when the work happens rather than by room.
Severance is one of the fastest-growing small towns in Colorado, and almost every house in it is new.
Why does a town of brand new houses call an insulation contractor?
It is a fair question. If everything here was built in the last ten or fifteen years, and all of it passed inspection, what is left to do?
Three things, and none of them are about the flat attic. Garages and the rooms above them. Unfinished basements that the buyer always intended to finish. And the difference between a house that meets code on paper and a house that holds a temperature on a 40 mile per hour night.
That is why this page is organized by when the work happens rather than by what room it is in. In Severance, timing changes the price more than almost anything else.
Building, finishing, or already living in it? All three are workable. Call (970) 414-2650
Before the drywall: the cheapest window you will ever get
If your house is still framed, or the basement is still studs and concrete, you are in the best possible position. Everything is reachable, nothing needs cutting, and nothing needs patching afterward.
The right scope at this stage is short. Closed cell foam on the rim joist band around the top of the foundation. Foam on any knee wall behind a bonus room closet. Foam or batts in the garage ceiling before the drywall goes up on it.
Closed cell earns its price here because it gives you R-6.5 to R-7 per inch plus an air barrier and a vapor retarder in one pass, which matters in shallow cavities and against concrete. That is the whole case for closed cell spray foam in a below-grade Severance basement.
If you are finishing the basement yourself, call before you buy lumber, not after. The rim joist is a two-hour job with the framing open and a much bigger one once it is covered.
Garage insulation for a new Severance build
Severance garages are big, often three cars, and they are the single most common thing we insulate in town. Two reasons for that, and only one of them is about using the garage.
The first is comfort in the space itself. An uninsulated garage here swings from single digits in January to well over 100 in July, which is rough on anything stored in it and unusable as a workshop.
The second is the room above. If there is a bedroom or bonus room over the garage, the garage temperature is that room floor temperature, full stop. Insulating the ceiling fixes a bedroom complaint that no thermostat adjustment will touch, and it typically runs $800 to $3,500 for a full Severance garage. That is garage and shop insulation, and it is usually a one-day job.
Do not skip the overhead door. A bare steel panel is the biggest single hole in most garage envelopes, and insulating the walls while leaving the door bare gets you a fraction of the result you paid for.

A few winters in: what plains wind does to a new house
Severance sits on open ground north of Windsor with almost nothing between it and the weather. New subdivisions make it worse for the first decade, before trees are tall enough to break anything.
Wind is not just a comfort issue. It pushes air through the building envelope and washes through fiberglass, which relies on still air inside its fibers to work at all. The house that felt fine in October feels leaky in a February chinook, and nothing about the insulation changed.
The fix is attic air sealing: the top plates, the recessed lights, the plumbing stacks, and the chase around the flue. It is the cheapest meaningful upgrade available to a Severance homeowner, and it is the one builders never include.
After a few winters, thin spots also show up in the attic itself, along whatever paths trades walked while finishing the house. Restoring depth with blown-in insulation is straightforward once the sealing is done.
Costs by stage of the build
Priced by stage, because that is how the decision actually gets made here. These are typical Northern Colorado ranges rather than quotes, and the real number follows a measurement.
| When the work happens | Typical range | What it covers |
|---|---|---|
| Framing stage, rim joist and knee walls | $900 to $2,600 | Closed cell, open access, no patching |
| Framing stage, basement foundation walls | $2.00 to $4.50 per sq ft | Closed cell against concrete |
| After move-in, garage walls and ceiling | $800 to $3,500 | Depends on ceiling, walls, and the door |
| After move-in, attic air sealing | $350 to $1,500 | Top plates, can lights, chases |
| A few winters in, attic top-up | $1,500 to $4,000 | Restore depth to R-49 or R-60 |
The federal 25C credit returns 30% of insulation and air sealing costs, capped at $1,200 per year, and it applies to your primary residence rather than to a builder contract, so timing matters for that too. Xcel Energy runs Colorado insulation rebates worth checking on its current sheet before you plan around an amount.
To try your own square footage before calling, the spray foam cost calculator returns a range in a few clicks, and the attic insulation cost guide explains what moves the number up or down.
Why insulation contractors Severance, CO ask for your drywall date
Severance sits between Windsor and Eaton, roughly twenty minutes from Greeley on county roads. New-construction work has to slot between other trades, so have your drywall date ready on the first call and the schedule gets built backward from it.
Spray foam needs surface temperatures above roughly 40 degrees to bond properly. In an unheated new build in January that means temporary heat, and that should be said up front rather than sprayed and hoped for.

Questions from Severance homeowners
When is the best time to add insulation to a new Severance home?
Before drywall, if you have the choice. Open framing means we can reach the rim joist, the knee walls, and the garage ceiling in one visit with no patching. After drywall the same scope costs noticeably more and some of it becomes impractical. If you are already moved in, the highest-value work is still available: garage, attic sealing, and the basement rim joist.
Why does my new house feel drafty when the builder insulated it?
Because insulation and air sealing are two different products, and only one of them is on the plan. Severance sits on open ground with very little windbreak, and wind drives air straight through unsealed top plates and can lights.
Fiberglass loses a meaningful share of its effective R-value when air is washing through it, which is why the same house feels fine on a calm night and bad on a windy one.
Is it worth insulating a garage I only use for parking?
If a bedroom or bonus room sits above it, yes, because the garage ceiling is that room floor. If nothing is above it and you never heat it, the honest answer is often no. We would rather tell you that on the phone than sell you a garage job that changes nothing you will notice.
What does a builder-grade attic in Severance usually measure?
Most new local construction lands near the bottom of the DOE climate zone 5B range, which is R-49 to R-60 for attics. That is compliant. What is typically missing is baffle continuity at the eaves and any real sealing at the attic floor, plus thin spots along the paths crews walked while finishing the house.
