Attic Star

Most homeowners have never seen the space under their own floor.

Here’s what we found — and what we did about it.

Old v***r barrier: torn, collapsed, soil moisture transferring directly into the framing above. Joists that had never fully dried. Insulation sagging from years of humidity. Foundation vents separating at the seams. Rodent entry points at three locations.

Here’s what went in:
— Old insulation and v***r barrier removed entirely
— New 20-mil v***r barrier, seams sealed and taped
— Rodent exclusion at all entry points
— New insulation installed and inspected

3 to 4 days. That’s the full job.

We’ve done thousands of attic walkthroughs. In the first 30 seconds, the same questions answer themselves.

Is there daylight coming through the eaves? Rodent entry.
Does the air smell different at floor level vs. shoulder height? Active moisture or contamination.
Are the floor joists level? Settlement or saturation below.
Is the insulation surface smooth, or are there trails running through it? Long-term activity.

The 30-min walkthrough doesn’t start when we open the hatch. It starts the moment we enter.

Temperature and humidity combine in ways most homeowners have never had to think about.

78°F and 85% relative humidity inside a crawl space isn’t uncomfortable — it’s mold conditions.

Not maybe. Not probably. Every time those two numbers line up, the biology starts.

The v***r barrier seams. The vent screens. The underside of the insulation. These are where it begins — the side you can’t see from any room in the house.

A 30-min inspection tells you whether yours is on the edge.

August feels like the peak of summer — but for your attic, it’s the worst month of the year.

The insulation has been absorbing heat since May. Duct seals that were borderline in spring are failing now. Foundation vents that had minor gnaw marks in June have been active entry points all summer.

The damage accumulates quietly. You feel it as higher energy bills, rooms that won’t cool down, or a smell that gets worse when the AC runs.

A 30-min inspection tells you exactly what August has done to your attic.

Every job starts before we open the hatch.

We look at the roofline first. At the HVAC exhaust. At the foundation vents.

By the time we’re inside, we usually already know what the problem category is. The inspection confirms it.

The 30-minute walkthrough isn’t a formality. It’s how we explain to the homeowner what the exterior already told us.

No pressure. No quote on the spot. Just what we see.

Flexible ductwork has a typical lifespan of 15–25 years.

After that, the inner liner begins to degrade. Connections loosen. Conditioned air leaks into the attic instead of reaching your rooms.

You feel it as:
— Rooms that stay warm even when the AC runs hard
— Electric bills that go up every year for no clear reason
— One room that’s always a different temperature than the rest

A 30-min attic inspection can identify duct failure before the next AC season.

This Kirkland crawl space hadn’t been inspected in 47 years.

What we found: original fiberglass insulation falling from joists, v***r barrier torn in 12 places, active moisture intrusion through three foundation vents, evidence of at least two seasons of rodent activity.

What we left behind: 6-mil encapsulation barrier sealed at every seam, new joist insulation to current spec, resealed vents, dehumidifier installed.

Four days. One crew.

The common knowledge: rodents try to enter homes in fall and winter, looking for warmth.

The PNW reality: dry Pacific summers push rodents to seek water sources inside homes starting in July. It’s a different mechanism — not warmth, but moisture.

We see more summer entry evidence in Renton, Kirkland, and Bellevue homes during July–August than any other two months.

The signs are subtle: gnaw marks near HVAC pipes, insulation disturbance around foundation vents, a smell that gets worse when the AC runs.
