Asbestos Testing & Removal in Richmond Hill
We are up in Richmond Hill most weeks, from the older streets around Mill Pond to the newer subdivisions past Elgin Mills.
Richmond Hill mixes older housing around Mill Pond and Yonge with large subdivision builds through Jefferson, Oak Ridges and Rouge Woods.
Oak Ridges sits on the moraine with a high water table, so sump systems run constantly and fail under load. Older areas near Yonge have aged drainage.
Asbestos was used in Ontario homes into the 1980s and is still present in a great many of them. It is not a hazard while it is sealed and undisturbed. It becomes one the moment somebody starts renovating, or when water damage forces material to be removed.
Covered by insurance? We bill your insurer directly, so in most cases you pay only your deductible.

What asbestos testing & removal in Richmond Hill costs you
We bill your insurance company directly. On most covered losses that is the only amount you pay us.
Water damage is the most common home insurance claim in Ontario, and the great majority of the work we do is paid by an insurer rather than by the property owner. We document every loss from the first hour with moisture readings, photographs and a written scope, which is the evidence an adjuster needs to approve the work without argument or delay.
We work with all major Canadian insurers and handle the claim from start to finish, including the adjuster's questions. If you are not insured, or the loss falls outside your policy, we will give you a clear written quote before any work begins and we will tell you honestly what can be dried and saved rather than replaced. Keeping material in place is what keeps the cost down, and it is the first thing we look at.
There is no charge for attending to assess an emergency, and no obligation once we have. What your policy covers →

How the insurance side works
Water damage is the most common home insurance claim in Ontario, and how the claim is handled usually matters more to your bill than the work itself. We document the loss from the first hour: moisture readings, photographs, a written scope, and a daily drying log. That is the evidence an adjuster needs to approve the work without arguing about it.
We bill your insurer directly. In most cases the only money you hand over is your deductible, which on Ontario policies commonly sits between $500 and $2,500.
Which losses are covered depends entirely on where the water came from. A burst pipe or a failed appliance is normally covered under a standard policy. Water coming up through a floor drain is sewer backup, which is almost always a separate endorsement you have to have purchased. Water entering from outside during heavy rain is overland flood, which is another endorsement again. A single storm can produce all three at once, which is why adjusters care so much about the source.

Common questions
Why does my Oak Ridges sump pump run constantly?
Oak Ridges sits on the Oak Ridges Moraine, where groundwater is high and steady. The pump is doing its job, but a system under constant load fails sooner, and a battery backup matters more here than most places.
Do you cover Richmond Hill overnight?
Yes. We attend Richmond Hill at any hour.
How do I know if I have asbestos?
You cannot tell by looking. It has to be sampled and analysed by a laboratory. If a building predates 1990 and you are planning to disturb the material, test first.
Is vermiculite insulation always asbestos?
Not always, but a large share of vermiculite sold in Canada came from a mine with naturally occurring asbestos contamination. It should be treated as containing asbestos until testing shows otherwise, and left undisturbed in the meantime.
What will asbestos removal cost me?
It depends entirely on whether the work is classed Type 1, Type 2 or Type 3 under Ontario Regulation 278/05, and that is decided by laboratory testing rather than a guess. We test first, then quote against a defined scope. Where asbestos is uncovered during a covered water loss, the removal often forms part of that claim.
Is asbestos removal covered by insurance?
Usually only where it forms part of a covered loss, for example when a flood requires removal of material that turns out to contain asbestos. Removal for renovation is normally an owner cost.
