Testimonials

Scott & Tim have been trusted partners for years in the West Island Homeowners Advisory Club. I recently experienced their professionalism and attention to detail first-hand after the August 9th flood hit my property. They responded immediately, and Tim took the time to assess the cause of the problem and recommend solutions to not only remediate the mould issue but to prevent it from happening again. They also helped one of my clients who was affected and moved mountains to get an air quality test done in time for the signing at the notary. Can’t recommend them enough. True professionals who know their stuff and can be trusted to do things right.
Scott Broady,October 13, 2024
Where do I start? Tim was such a help to us during such an incredibly difficult time. We had a leak, we called him in and he walked us through the process in great detail. He started his work and then we were hit by the floods in August. The damage tripled after the flood and he stayed on it and with us every step of the way. He gave us great insight and feedback so that we could make informed decisions as homeowners. We had very limited knowledge of things until we met Tim, he really walked us through the ins and outs of everything and we feel better equipped with our basement rebuild. Thank you so much for being there during such a difficult time! We have been and will continue to refer our friends and family to Sterimobile!

Before & After

Mold removal

Common areas of the home where mold is found

1. Attics

Attic mold is typically discovered on the sheathing and trusses because of lack of ventilation. This occurs for the following reasons:

  • The soffits are blocked not allowing proper air flow
  • Bathroom fans are vented into attic or soffit
  • Maximum vent and gable vents are both open resulting in incorrect air flow
  • Vapor barrier installed on back of insulation is degraded allowing more hot air to rise from the house than can be ventilated out the vents

Do you have mold in your attic? Click here to learn more about Steri Mobile’s mold remediation process specifically for attics.

2. Bathrooms

Bathroom mold is a result of hot moist air being trapped in the room and not being exhausted. The condensation will then turn into mold

3. Kitchens

Kitchen mold is usually a result of a plumbing system that has leaked at some point. The resulting water after 24-48 hrs. will turn into mold

4.Basement Mold

Basement mold can be created for a variety of reasons. Bottom line, there is water penetration, which results in the formation of mold. Some reasons could be:

  • The foundation taking on too much water. Remember cement is porous and can only hold so much water.
  • The exterior siding/brickwork has improper drainage.
  • Basement window caulking degraded
  • Deck flashing improperly installed

Why should mold be eliminated?

When left untended, mold can cause a lot of damage. Mold, mildew and fungus pose three great risks:

  • Material deterioration: Prolonged moisture and mold growth can stain finishes, and weaken drywall, wood, and insulation. This can cause significant damage to your home if the problem is not addressed immediately.
  • Airborne spores & allergens: Mold and fungi release spores, which are their way of reproducing. These spores float around in the air of the home and pose inhalation risks to those living in the home. These spores are considered to be a major allergen and rank with pollen as a main source of contaminants for allergy sufferers.
  • Some species produce mycotoxins: Some types of molds and fungi release highly toxic “mycotoxins” which are by-products that develop and then are released during growth. These mycotoxins can cause severe adverse health problems for many people.

Mold should not be allowed to grow indoors. When this happens, health problems can occur, and building materials, goods, and furnishings may be damaged. Prompt mold remediation helps protect occupants and prevent costly structural repairs.

FAQs on Mold Removal & Remediation

Do I need testing before remediation?
How long does a typical job take?
Will the mold come back?
What does your two-year warranty cover?
What’s included in your estimate?
Do I need testing before remediation?

Not always. If the source and growth are obvious, we can proceed with remediation. When conditions are unclear or you need documentation, we can arrange air/surface sampling. Prefer an assessment first? Contact us to book a mold inspection.

How long does a typical job take?

Most small projects take 3-4 days, depending on area size, access, and drying needs. Larger or multi-room projects can take longer. We’ll confirm timelines after inspection.

Will the mold come back?

We remove existing growth and reduce airborne spores. Preventing recurrence depends on fixing the moisture source (leaks, humidity, ventilation). We’ll identify the source and provide clear recommendations.

What does your two-year warranty cover?

Our warranty covers the remediation work we performed in the treated area. It does not cover new moisture events or repairs that the property owner must complete. Full details provided with your estimate.

What’s included in your estimate?

We typically include the following in our estimate: scope of work, containment plan, materials to be removed, treatment steps, safety measures, documentation/post-remediation verification (PRV) details, timeline, and pricing.
