What we do
Insulation Services, Done Right
Attic insulation, blown-in, batts, spray foam, air sealing, radiant barrier, crawl-space systems and removal — one licensed local crew for the whole envelope.
Attic InsulationNew or topped-up attic insulation, installed to a consistent depth across every joist bay — the single biggest comfort upgrade most homes can make.Learn more →
Blown-In InsulationLoose-fill fiberglass or cellulose blown to a measured depth — it fills around wires, pipes and joists where batts leave gaps.Learn more →Fiberglass Batt InsulationPrecision-cut fiberglass batts for walls, floors, ceilings and crawl spaces — fitted snug, never stuffed or compressed.Learn more →
Spray Foam InsulationSpray foam that insulates and air-seals in one application — for roof decks, rim joists, crawl spaces and the spots nothing else can reach.Learn more →
Air SealingWe hunt down the leaks — attic hatches, top plates, pipe and wire penetrations, recessed lights — and seal them. Insulation's essential partner.Learn more →Crawl Space & Basement InsulationWarm floors, protected pipes, drier air — crawl-space walls and ceilings, vapor barriers, and basement rim joists done as one system.Learn more →
Radiant Barrier InstallationA reflective barrier under the roof deck that reflects radiant heat back out — for attics that bake in summer and rooms that feel it below.Learn more →Insulation Removal & ReplacementOld, wet, pest-damaged or fire-and-smoke-affected insulation vacuumed out and replaced — a clean attic floor, sealed and re-insulated in one project.Learn more →Comfort, honestly
The Signs Your Insulation Is Falling Short
Your house reports its insulation problems in plain language — uneven rooms, restless equipment, winter ice. These are the complaints that trace back to the attic and the crawl space:
The upstairs bakes in summer
A sun-heated roof radiates through a thin attic floor into the bedrooms below. The air conditioner fights the attic all afternoon — and loses.
Rooms that never agree
One room roasts, another freezes. Uneven insulation and uneven leaks make uneven houses, and the thermostat can't arbitrate physics.
Cold floors in winter
A floor over a vented, uninsulated crawl space is a floor over outdoor air. The fix lives underneath the house, not in a thicker rug.
Ice dams on the roof edge
Heat escaping through the ceiling melts roof snow, which refreezes at the cold eave. An attic problem wearing a roof costume.
The HVAC never rests
When the boundary leaks, the equipment compensates — longer cycles, more wear, same discomfort. The system isn't failing; the envelope is.
Drafts from nowhere
Chilly air at outlets, a cold halo around the attic hatch, a basement that breathes. Air leaks announce themselves — sealing answers them.
The defense is unglamorous and total: seal the leaks, install to a measured depth, and treat the crawl space as part of the house. That's exactly what we do — start with the sealing if you want to understand the order of operations.
How it works
A Tighter Home in Four Steps
Assess
We measure your existing insulation, map the air leaks and photograph everything — evidence first.
Seal
Leaks in the ceiling plane and rim joists are closed, so new insulation can do its rated job.
Insulate
New material goes in to a consistent, verified depth — attic, walls or crawl space.
Verify
Depth is checked across the whole job and you get the photos. Comfort is the receipt.

Good to know
Insulation Questions, Answered Straight
The symptoms are the tell: an upstairs that's hot all summer, rooms that never match the thermostat, floors that freeze over the crawl space, ice dams in winter, an HVAC system that rarely rests. The proof is simpler: a look in the attic. If the insulation sits at or below the tops of the joists, or you can see bare patches, your home is under-insulated by current standards. Our free assessment measures it and shows you in photos.
It depends on the area, the material and what's already there — which is why the assessment and the written quote come first, free, with no obligation. You'll see your options priced in writing before any work begins, and the price we quote is the price you pay.
The attic, almost always. Heat rises, the attic floor is the biggest single boundary in the house, and it's the most accessible — the best return per dollar lives up there. Walls matter, but they're a later, more involved project for most existing homes.
Because insulation doesn't stop moving air. Heated air escaping through gaps around pipes, wires, lights and the hatch carries its heat with it no matter how deep the insulation is. Sealing first is what lets new insulation perform at its rated value — skipping it is the most common reason insulation jobs disappoint.
Most attic jobs — sealing included — finish in a day. Crawl-space systems, removal projects and spray-foam assemblies can take longer; your written quote includes a realistic schedule.
