Attic Mold Removal in Greeley, CO

OSB sheathing and plywood roof deck develop two distinct mold presentations: superficial surface colonization on structurally sound material (treatable in place), and through-penetration with structural delamination (requiring sheathing replacement). We assess each section individually and recommend replacement only where structural integrity is actually compromised.

Exhaust Fan Termination Audit
We check every exhaust fan termination point in your Greeley attic — bathroom fans, kitchen range hoods, dryer vents — before proposing any mold treatment. Fans venting into the attic instead of to the exterior are identified and rerouting is included in the remediation scope where this is confirmed as the moisture source.

Sapstain vs. Active Mold Distinction
Sapstain vs. active mold matters because they require different responses and carry different health implications. We confirm before recommending treatment — you don't pay for remediation of a pre-existing cosmetic condition.

Soffit-to-Ridge Ventilation NFA Calculation
Actual NFA vs. required NFA for your Greeley roof — calculated from vent count, size, and blockage. Specific correction identified, not generic ventilation advice.

Flat-Rate Written Scope — Post-Assessment
Attic mold scope is determined after we've assessed the sheathing section by section, confirmed species via sampling where warranted, measured MC%, and audited the ventilation and fan termination points. Flat-rate written estimate after that assessment — not a square-footage estimate from square one.

What Our Greeley Attic Mold Crew Does

From sheathing assessment through fan rerouting and ventilation correction — the full above-ceiling mold scope for Greeley, CO properties.

Assessment
🔍Sheathing Assessment & Sapstain Distinction
Section-by-section sheathing assessment: MC% readings, visual characterization of growth pattern, and targeted lab sampling where species or activity status is uncertain. Structural assessment of OSB and plywood sheathing for delamination or through-penetration. Sapstain documented separately from active mold growth.
Ventilation
💨Soffit Vent Clearance & Ridge Vent Assessment
Eave bay clearance and baffling, ridge vent condition assessment, vent addition where NFA is insufficient. All specified in the written scope with the reason for each correction.
Fan Rerouting
💨Exhaust Fan Rerouting to Exterior
Bathroom fans, kitchen fans, and dryer vents identified as terminating inside the Greeley, CO attic are rerouted to the exterior — through gable, soffit, or roof cap — using properly insulated flex duct or rigid metal, sealed at the fan housing and at the exterior penetration. This is typically a same-day correction.
Treatment
🌳Borate Treatment & Encapsulant Application
EPA-registered penetrating borate applied to all accessible sheathing and rafter surfaces after HEPA vacuuming of loose spore material. Optional mold-resistant encapsulant applied over borate-treated surfaces where additional barrier protection is warranted — typically on south-facing or warm-roof sections with historically higher moisture loads.
Replacement
🔨Sheathing Replacement Where Structurally Needed
Individual section assessment for structural compromise. Replacement recommended only where structural assessment confirms it's needed. Roofing contractor coordination for sections requiring cover removal.
Clearance
✅Post-Remediation Clearance & MC% Verification
After treatment and ventilation correction, post-remediation sheathing MC% readings verify material is below threshold. Independent post-remediation air sampling from within the attic and from living spaces below confirms reduced spore counts in both zones. Written clearance report delivered.

Client Reviews

Attic Mold Reviews — Greeley, CO

★★★★★
Roofing crew found mold on the underside of our Greeley attic sheathing during a re-roof job. Cheap Mold Removal assessed it — two bathroom fans venting directly into the attic, blocked soffit bays from blown-in insulation, and OSB sheathing with MC readings at 21%. They rerouted both fans, cleared and baffled the eave bays, treated all sheathing with borate, and the post-clearance air sampling confirmed clean attic and living space air. Haven't had a recurrence in 18 months.

★★★★★
Post-hurricane attic assessment for our Greeley commercial building. Water intrusion along the eave edge had saturated insulation and sheathing in two bays. Cheap Mold Removal removed the saturated insulation, assessed the sheathing for structural compromise, treated the affected framing, replaced two sections with confirmed delamination, and produced clearance documentation for our insurance carrier.

★★★★★
Cheap Mold Removal saved us from an unnecessary $6,000 attic remediation. The other contractor quoted full sheathing replacement across the entire attic. Cheap Mold Removal's assessment found that 80% of the visible staining was sapstain from the OSB (confirmed by lab sample showing no active mold species), with only two sections near a blocked soffit bay showing actual active growth. They treated the two active sections and cleared the blocked soffit. Total job: $1,100 vs. a $6,000 quote that would have treated lumber that didn't need treating.

Frequently Asked Questions

What Greeley Homeowners Ask About Roof Deck Mold

Two root causes account for most Greeley attic sheathing mold: improperly terminated exhaust fans and blocked/insufficient soffit-to-ridge ventilation. Both create the same condition — warm moist air in the attic unable to exit, condensing on cold sheathing surfaces. We find which one (or both) is present in your Greeley, CO attic before proposing any treatment scope.
Sapstain is a common cause of unnecessary attic remediation in Greeley, CO. We confirm whether staining is active mold or pre-existing sapstain before recommending any treatment — if it's sapstain, we'll tell you and save you the remediation cost.
In-place treatment is appropriate for structurally sound sheathing. Replacement is needed only for sections with confirmed structural compromise. We assess each section individually and recommend replacement only where structural assessment warrants it — not as a default that maximizes job size.
Our initial attic assessment traces every exhaust fan duct from its housing to its termination. Improperly terminated fans are identified and rerouting is specified in the remediation scope. You'll know definitively after our assessment whether fan termination is contributing to your Greeley attic mold problem.
We treat wood structural components only — sheathing and rafters — and do not apply products to roofing materials. Our treatment products have SDS sheets available on request, and we can provide these to your roofing material manufacturer representative for verification of compatibility. Most manufacturers don't restrict attic wood treatment by qualified contractors, but if you have a specific manufacturer warranty question, we recommend confirming directly before scheduling work.
