Sound familiar?

The signs your attic insulation is failing

Most calls start with one of these. The inspection tells us whether you need a top-off, a full removal and replace, or just air sealing.

The second floor is always too hot in summer
Cold rooms and uneven temperatures in winter
Energy bills that keep climbing
Old, thin, compressed, or dirty insulation
Animal damage, odor, or torn-up material
Not sure whether a top-off is enough

The building science

Why most attic insulation underperforms

Topping off over the wrong attic just buries the problem. Three things decide whether insulation actually works, and all three happen before new material goes down.

25-40%

Air leaks come first

Air leakage accounts for 25 to 40% of the energy used to heat and cool a home. Insulation slows heat but does not stop air. Fiberglass and cellulose are air-permeable, so the leaks get sealed first, or new insulation underperforms from day one.

0 mold

Ventilation keeps it dry

Blocked soffit vents trap moisture in the attic. Baffles keep that airflow moving so moisture is carried out before it condenses into mold, rot, and premature insulation failure.

Bury it

Old material does not just disappear

Wet, compressed, or contaminated insulation has lost most of its R-value, and animal damage or odor stays trapped under a fresh layer. We decide what comes out during the inspection instead of topping off over a problem.

How the job runs

Inspect, decide, seal, install, document

One crew, the full job, in the order that actually performs. The sequence is the part most companies skip.

1

Inspect the whole attic

We document insulation depth, condition, air leaks, ventilation, moisture, odors, and damage, with photos and a written report you keep.

2

Decide what stays

Clean, dry, performing insulation may only need a top-off. Wet, compressed, contaminated, or animal-damaged material gets removed, not buried under a fresh layer.

3

Air seal before install

Gaps at can lights, top plates, plumbing stacks, hatches, and bypasses get sealed first. ENERGY STAR is explicit: seal the attic-floor leaks before adding insulation to get the full performance out of it.

4

Install the right material

Fiberglass batt, blown-in fiberglass, or cellulose, installed to the right depth for your attic. The material comes from the inspection, not a price sheet.

5

Photo closeout

Before, during, and after photos of the full job. You see exactly what was removed, sealed, and installed without climbing a single rung.

Lower bills

Air sealing and insulating together make a real difference in heating and cooling costs. Most homeowners notice it the first season.

Backed by ENERGY STAR

Batt, blown-in, or cellulose

The right material is a measurement, not a preference

Each material has a different R-value per inch (US DOE), so the one that fits your attic depends on your framing and target. Here is where each one wins.

Fiberglass batt insulation precisely installed between attic joists

Fiberglass batt

R-2.9 to R-3.8 per inch

Best when framing is standard and joist bays are accessible. Clean, consistent coverage that is easy to verify after installation.

Blown-in fiberglass insulation being installed across an attic floor

Blown-in fiberglass

R-2.2 to R-2.7 per inch

Best for irregular framing and tight spaces where batts would leave gaps. Fills cavities completely and works well as a top-up over existing material.

Finished blown-in insulation covering an attic floor evenly

Cellulose

R-3.2 to R-3.8 per inch

Highest R-value per inch of the three. Dense-packs well for enclosed cavities and retrofits. It settles over time, so we factor that into the installed depth.

Before and after

The difference, in real attics

Old, thin, or contaminated insulation comes out. Clean, even coverage goes in. These are real jobs, documented start to finish.

Get a written insulation estimate

We inspect the attic, document the condition, and put the full plan in writing before any work starts.

Big job? We offer financing through Wisetack. Checking your options takes about a minute and does not affect your credit score.

Do I need new insulation, or just more?
That is exactly why we inspect first. If the existing material is clean, dry, and still performing, a top-off may be enough. If it is wet, compressed, contaminated, or damaged, removal and replacement is the right call.
Do you air seal as part of the job?
Yes. Adding material over leaks leaves the comfort problems in place. We check the attic floor, penetrations, hatches, and common bypasses before any new insulation goes in.
How much does attic insulation cost?
It depends on attic size, access, current condition, whether removal is needed, and whether air sealing is included. We inspect first and give you a written estimate based on what your attic actually needs. Financing is available.
Can you remove animal-damaged insulation?
Yes. If insulation was damaged by mice, squirrels, raccoons, moisture, or odor, we plan the removal before new material goes in. We do not cover contaminated insulation with a fresh layer.
What type of insulation do you install?
Fiberglass batt, blown-in fiberglass, and cellulose, depending on attic layout, access, and the target result. We recommend the material after inspecting, not from a script.
Is the inspection really free?
Yes. We inspect the attic, explain what we found, and give you the full plan in writing before any work starts. No pressure.
