Frequently asked questions

Most homes do well on a 2 to 3 year cycle. Clean them sooner after renovation work, after moving into a home (even a brand new one), or if anyone in the home has allergies or asthma.

Yes. Construction dust, drywall powder, sawdust and debris settle in the duct work while the home is being built. We strongly recommend cleaning the ducts before you move into a new home.

Dust building up around vents shortly after cleaning, musty smells when the system runs, uneven airflow between rooms, and worsening allergies indoors are all common signs.

A typical single-family home takes 2 to 4 hours depending on the size of the home, the number of vents, and how much buildup is in the system.

No. We use contained, negative-air equipment that pulls debris out of the ducts and into our collection system. Registers are sealed during cleaning and we leave the home as clean as we found it.

Lint is highly flammable and clogged dryer vents are a leading cause of house fires. A restricted vent also makes the dryer run longer, which wastes energy and wears out the machine.

Once a year for most households. Large families, heavy laundry use, long vent runs, or vents with several turns may need cleaning every 6 months.

Clothes taking more than one cycle to dry, the dryer feeling hot to the touch, a burning smell, the laundry room feeling humid, or lint collecting around the exterior vent flap.

The whole line. We clear the full run from the dryer to the exterior wall or roof cap, then confirm strong airflow at the outside vent before we finish.

Musty odors, visible spotting on walls or ceilings, past water damage, and unexplained allergy symptoms indoors are common indicators. If you are unsure, we can test the air and surfaces to confirm.

Bleach lightens the surface stain but rarely kills mold at the root on porous materials like drywall and wood, and it does nothing about spores in the air. Proper remediation contains the area, removes affected material, and treats the source of moisture.

Mold can trigger allergies, asthma attacks and respiratory irritation, and some species produce toxins. Children, older adults and anyone with a compromised immune system are most at risk.

Not if the moisture source is fixed. Mold needs moisture to grow, so every remediation includes identifying and addressing what fed it in the first place.

Depending on your concerns we test for mold spores, allergens, volatile organic compounds (VOCs), humidity issues and particulates. You get clear results and a plain-English explanation of what they mean.

After water damage, before buying a home, when someone in the home has unexplained respiratory symptoms, or any time you smell something musty but cannot find the source.

Call us as soon as it is safe. Water and smoke damage get worse by the hour. We extract water, dry the structure, remove smoke residue and odor, and document everything for your insurance claim.
