Why homeowners call Mold Removal Experts

A written quote first

You get a written scope and price for your specific property before any work begins, not a verbal number that changes later.

Open every day, 7 AM to 11 PM

Active water damage or a sudden mold problem does not wait for a convenient moment, so our phone line is open every day, morning through late evening.

Contained, careful removal

Every job uses proper containment and negative air pressure sized to the area, so spores do not spread to the rest of the property during work.

What every project includes

A real inspection first

We look at the affected area, take moisture readings, and identify the source before recommending a scope of work.

Containment sized to the job

Small spot removals use basic containment. Larger or structural jobs get full containment with negative air pressure and HEPA filtration.

A written quote, job by job

Every project gets a written scope and price before work starts. Any workmanship warranty is set out in that quote, not promised verbally.

A walkthrough when it is done

You see the finished area and understand what was done before we consider the job complete.

Why Ottawa homes get mold

What causes mold in Ottawa homes

Ottawa’s freeze-thaw winters and clay-heavy soil in many neighbourhoods put real, ongoing pressure on basements and foundations, and a burst pipe or ice-damming event can turn into a mold problem within 24 to 48 hours if it is not dried out fast. Older housing stock across the city, common in neighbourhoods built before the 1980s, often has original waterproofing that has never been replaced, while newer, tightly sealed homes can trap humidity if bathroom fans and HVAC systems are not balanced correctly. Whatever the cause, the fix is the same: find the moisture source, remove the mold safely, and confirm the area is dry before closing it back up.

How fast can you respond to an active mold or water damage situation?

Our phone line is answered every day from 7 AM to 11 PM, and we prioritize active water intrusion or urgent mold situations as quickly as we can within those hours. Same-day visits are made for active emergencies; other visits are booked by appointment. Routine inspections and quotes are usually scheduled within one business day.

Do I need testing, or just an inspection?

An inspection is a visual, on-site assessment with moisture readings, usually enough to scope a visible problem. Testing adds lab-analyzed air or surface samples, useful when mold is suspected but not visible, or when you need documented results.

Is Mold Removal Experts insured?

We are a newer company and would rather say that plainly than claim something we cannot back up in writing yet. Ask us directly about our current insurance status before booking, and we will give you a straight answer.

Do you serve my part of Ottawa?

Yes. We work across the City of Ottawa and surrounding communities. See our service area pages for local details, or contact us directly with your address.

How is pricing determined?

Price depends on the size of the affected area, how accessible it is, the containment level required, and whether any material replacement is needed. Every project gets a written quote before work begins, either from an on-site visit or clear photos.

What is included in a written quote?

The scope of work, the containment approach, an itemized or all-in price, and the timeline. Any workmanship warranty is set out in that quote, job by job, rather than promised as a blanket guarantee.
