Woodbridge: two bathroom fans were venting straight into the attic — caught before it needed a full gut

1The Problem

Three inches of insulation over a big attic is a heat-loss problem you can feel in your feet every January. The furnace fights it all winter; the A/C fights the reverse all summer.

2What the Inspection Found

Our exhaust rating for this attic was 1 out of 5 — the worst score we give. Both bathroom exhaust fans were venting directly into the attic instead of through the roof. Every shower, all that steam had been blowing straight onto cold wood. The result: moisture staining across roughly 500 sq ft of sheathing. The good news — because it was caught early, the wood was stainable-but-sound and the existing insulation was still salvageable.

3How We Fixed It

Because we caught it early, this was a repair-and-top-up — not a gut:

• Installed two dedicated bathroom roof exhaust vents with insulated vent pipes — moisture now exits the house, full stop
• Added a tower roof vent plus 16 baffle vents with soffit cover-up for proper passive airflow
• Cleaned and restored the 500 sq ft of stained sheathing, with a salt-based protective sealant on the worst 200 sq ft
• Air-sealed the ceiling penetrations and upgraded the attic hatch
• Topped the whole attic up from R-8 to R-60 — no removal needed

4The Result

The upstairs finally holds its heat, the showers vent outdoors, and the homeowner avoided the cost of a full removal because the problem was caught before the mold took hold. That’s the whole argument for a free inspection: the earlier we look, the cheaper the fix. 10-year workmanship warranty included.

5The Short Version

In Woodbridge, a cold upstairs led to the worst exhaust score Confirmed Attics & Insulation gives: 1 out of 5. Both bathroom fans were venting directly into the 1,400 sq ft attic, blowing shower steam onto cold wood for years and staining roughly 500 sq ft of roof sheathing — over insulation that measured only about 3 inches, roughly R-8. Because it was caught early, the wood was sound and the insulation salvageable. The crew installed two dedicated bathroom roof vents with insulated pipes, added a tower roof vent and 16 baffle vents for passive airflow, cleaned and restored the stained sheathing with protective sealant on the worst 200 sq ft, air-sealed the ceiling penetrations, upgraded the hatch, and topped the attic up from R-8 to R-60 — no removal needed.
