Roof sheathing cleaning
Plywood and OSB decking with dark staining is cleaned with dry ice blasting, soda blasting, or HEPA sanding, depending on severity and the contractor's equipment.
Attic mold almost never comes from a single leak. Call Breffni Remediation and we'll connect you with an independent attic mold pro in Berkeley who removes the growth and fixes the airflow problem underneath it.
Most attic growth comes down to three issues: exhaust fans venting into the attic, blocked soffit vents, and air leaks from the house below. Cleaning without fixing them doesn't last.
Answered day and night, holidays too.

Here's what separates a real attic fix from a quick spray job.

Each part of the job, from blasting to new baffles, is priced in writing before work begins.
Contractors use media blasting or hand cleaning, HEPA vacuums, and air filtration suited to working overhead in a tight attic.

Every independent contractor we connect you with is expected to be properly insured and licensed where required.
Attic work combines cleaning overhead with fixing how air moves through the house. These are the core services.
Plywood and OSB decking with dark staining is cleaned with dry ice blasting, soda blasting, or HEPA sanding, depending on severity and the contractor's equipment.
Fans and dryer vents that end in the attic get rerouted outside, removing a major moisture source.
Proper attic airflow needs open intake at the eaves and exhaust at the ridge. Contractors restore that balance.
Contaminated blown cellulose or batts may need removal. Air sealing around top plates, recessed lights, plumbing stacks, and the attic hatch cuts the warm air leaking up from the house.
Once the decking is clean, some contractors apply an antimicrobial or a fungicidal encapsulant coating. It doesn't replace cleaning or ventilation fixes, but it adds a layer of protection.

A few recent attic jobs.

The north slope of our roof deck was covered in dark stains. The contractor found both bathroom fans venting straight into the attic. They dry ice blasted the decking and ran the ducts out through roof caps.
Every winter we'd get water spots on the bedroom ceiling. It turned out to be frost on the nails melting. They cleared the soffits, installed baffles, and sealed around the can lights. No spots this year.
A new roof was already on the schedule, so the contractor cleaned the sheathing first and coordinated with the roofer on adding a ridge vent. Good timing saved us a second trip.
Photos of the cleaned attic saved our closing. The buyer's agent had questions and the report answered every one of them.
Usually warm, humid air from the house condensing on cold roof sheathing, made worse by exhaust fans venting into the attic, blocked soffit vents, or poor air sealing. Roof leaks are another cause.
It can still damage the roof deck and insulation, and it often becomes an issue when you sell.
Usually not. Most stained sheathing can be cleaned. Replacement is only needed when the wood is soft, delaminated, or structurally compromised.
It's a method that fires dry ice pellets at the surface to knock off growth. The dry ice turns into gas, leaving no water or grit behind, which suits attic sheathing well.
They shouldn't. Ducting them outside is a simple fix that often solves the problem at its source.
Typically a day or two for cleaning, plus time for ventilation or insulation work.
