What We Do

Find It, Contain It, Remove It — and Fix Why It Grew

Mold is never the real problem — it’s the symptom. Somewhere, moisture got in: a slow supply-line leak, a poorly-dried water loss, a humid crawlspace, groundwater wicking through a foundation. Remediation that doesn’t fix the moisture source is remediation you’ll pay for twice. Keystone treats every mold job as both a removal project and a moisture investigation.

Inspection and testing first

We start with a thorough inspection: moisture meters and thermal imaging to trace water paths, and visual assessment of affected materials. We test before remediation when it helps set the scope. We don’t do post-remediation testing on our own jobs, because grading our own work would be a conflict of interest; an independent tester is the right option for clearance. You get straight answers about what you have and what it takes to fix it, not scare tactics.

Containment is everything

Disturbing mold without containment spreads spores through your entire home. Before removal begins, we seal the work area with plastic sheeting and run negative air pressure through HEPA filtration, so spores stirred up by the work are captured — not circulated. Technicians work in full protective equipment, and affected porous materials are bagged and removed safely.

Removal, treatment, and prevention

Mold-damaged drywall, insulation, and carpet are removed; salvageable framing and structural surfaces are cleaned, treated with antimicrobials, and dried to verified standards. Then we address the cause — repairing the moisture source and, where useful, improving ventilation or drainage — and our sister company Keystone BuildWorks restores the finished space.

A Mold Job, In the Customer’s Words

★★★★★

“Dealing with mold can be pretty overwhelming, but having someone who communicates well throughout the process makes all the difference. Seth was great about keeping me in the loop about what was happening and what came next. I never felt like I was in the dark about the timeline or the steps they were taking. The work itself was thorough, and they made sure to explain things in a way that actually made sense. When you’re dealing with something like this, you want to feel confident that it’s being handled properly, and that’s exactly what happened here.”

Straight Answers

Mold Questions, Answered

What Utah homeowners ask us about mold, health, and coverage.

Is mold in my house dangerous?

It can be. Mold exposure commonly causes allergy symptoms, asthma flare-ups, headaches, and respiratory irritation — and people with compromised immune systems face more serious risks. Just as important: visible mold means a moisture problem is actively damaging your home. Both the mold and its water source need to be fixed.

Can I just clean mold with bleach?

No — bleach on porous materials like drywall and wood kills surface mold while leaving roots intact, and the water in bleach can actually feed regrowth. Worse, scrubbing releases spores into the air and spreads the problem. Mold beyond a few square feet should be professionally contained and removed under negative air pressure.

How do I know if I have mold behind my walls?

Warning signs include a persistent musty smell, unexplained allergy symptoms that improve when you leave home, staining or bubbling paint, and any history of water damage that wasn’t professionally dried. Keystone uses moisture meters and thermal imaging to find hidden moisture. We test before remediation when it helps set the scope. We don’t do post-remediation testing on our own jobs, because grading our own work would be a conflict of interest; an independent tester is the right option for clearance.

Does homeowners insurance cover mold remediation?

Coverage depends on your policy and on what caused the mold, so check your policy or ask your agent. If it is a covered loss, we bill your carrier directly. Keystone documents the moisture source carefully — that documentation often determines coverage.

How long does mold remediation take?

Most mold jobs take 1 to 3 days. After the work, the area airs out for an hour or two before anyone goes back in. Rebuild of removed materials follows. Severity and the size of the affected area drive the timeline, and we give you a clear schedule up front.

How much does mold remediation cost in Salt Lake County?

At Keystone Restoration’s 2026 rates, mold remediation in Salt Lake County comes to about $1,900–$2,350 for a bathroom and $3,650–$4,400 for a section of basement, labor included. Rebuild is quoted separately. See theitemized mold remediation pricingfor the line-by-line examples.
