Asbestos risk before a basement tear-out

This index does not price an asbestos test. What its records do show is that testing and removal sit in different places: 13 of the 294 listed companies carry the Google Maps label asbestos testing service, 14 are labelled environmental consultant, and 10 companies appear under mould inspection and testing with no removal category attached.

Key facts

  1. 01Thirteen of the 294 listed companies carry the Google Maps business label asbestos testing service, and 14 are labelled environmental consultant.
  2. 02DeSa Contracting prices tear-out and removal of soaked drywall, carpet and insulation at $500 to $3,000 per job in its Toronto guide.
  3. 03No cost guide or comparison page on this site prices an asbestos test, an air clearance for asbestos, or abatement work of any kind.
  4. 04Ten records appear under mould inspection and testing with no removal category anywhere in the index; the other 49 in that category of 59 also carry a removal listing.

What the index records about asbestos

The business labels above come from Google Maps, not from this site's own six categories. Across the 294 records, 211 carry the label water damage restoration service, 29 building restoration service, 14 environmental consultant, 13 asbestos testing service, 9 fire damage restoration service, 4 general contractor, 4 plumber, 2 construction company, 2 home inspector and 2 remodeler, and a handful of records fall outside those ten labels. That is the full extent of what the index knows about how each business describes itself.

Six records carry the word asbestos inside the business name. Two examples: MAS Mold & Asbestos Inc. in Kensington Market, filed under mould inspection and testing with no rating on record, and Toronto Mold Asbestos Removal Pros in Islington-City Centre West, filed under mould inspection and testing plus mould removal, with a 4.9 rating across 29 reviews. A name is a marketing decision, and the index has no field that confirms what any of the six actually sample for.

The gaps matter more than the labels here. None of the site's six cost guides and none of its three comparison pages prices an asbestos test, an air clearance for asbestos, or abatement work of any kind. The cost research behind this site covers water damage, mould removal, mould inspection, sewage cleanup and fire restoration, and stops there. The listing records hold no licence status, no certification, no years in business and no scope of work for any of the 294 companies. Email is absent on every record; a website appears on 259 of 294 and a phone number on 291 of 294.

Where tear-out sits in a flooded basement bill

Tear-out is the demolition step in the middle of a flood job. DeSa Contracting's Toronto guide prices tear-out and removal of soaked materials, listing drywall, carpet and insulation, at $500 to $3,000 per job. The same guide prices emergency water extraction at $500 to $3,000, structural drying and dehumidification with industrial equipment over three to five days at $800 to $4,000, and sanitization with antimicrobial treatment and deodorizing at $200 to $1,000. Junk Professionals prices contents disposal and junk haul-away of flood-damaged belongings at $250 to $700 per half-to-full truckload. Restoration Mate prices a full finished-basement flood restoration including rebuild at $5,000 to $25,000. Every figure is quoted before 13% HST.

Read as a sequence, the demolition line is one of the smaller numbers on the invoice and the one that governs what leaves the building. How much comes out tracks water depth. Advanced DRI's depth framework, used here only for structure, sorts the damage this way: under 1 inch may only affect flooring, 1 to 6 inches saturates drywall and baseboards, 6 to 24 inches reaches outlets, furnaces and HVAC, and more than 24 inches usually means a gut and rebuild plus electrical inspection. Toronto contractors price the resulting damage class rather than the depth itself, which is why the same flooded room can be quoted thousands of dollars apart. Full ranges for the whole job sit on the basement flood cleanup cost page.

Testing and removal are separate entries in this data

Ten of the 294 records appear under mould inspection and testing and in no removal category: Toronto Environmental Services + Toronto Asbestos Removal Inc. in Willowdale, Technominds Home & Mold Inspections in Brampton, EnviroSolve Canada Inc in Mimico, Safeway Demo & Environmental Services in Brampton, Decon Environmental Remediation Inc. in Brampton, SLR Consulting (Canada) Ltd. in the Financial District, T Harris Environmental Management Inc. and Enviro Management in Islington-City Centre West, MAS Mold & Asbestos Inc. in Kensington Market, and AirQualityInspections.ca in Lawrence Park. The other 49 companies in that category of 59 also carry a removal listing.

That count describes how listings are filed on this site. It is not proof that any of the ten declines removal work, and it is not a licence check. The distinction still matters when you are choosing who writes the report, because the cost research behind this site records two things about the GTA market: Ontario has no licensing requirement for mould remediation or water damage restoration, so anyone can advertise the service, and many remediation contractors in the region offer free inspections that function as sales calls for remediation work. The same research recommends hiring an inspection firm separate from the remediation firm, on the grounds that self-referral inflates scope in an unlicensed market. Independent assessors in Toronto tend to quote by phone rather than publish rates.

What an inspection costs when the subject is mould

Published GTA inspection pricing is consistent enough to budget from. Restoration Mate prices a visual mould inspection with a written report, no lab samples, at $150 to $400 per visit. The Mold Guy prices a standard package with two or three air or surface samples for a home up to 2,000 square feet at $350 to $770 including lab analysis, with extra samples at $60 to $120 each. Mold Inspection Canada prices a single air sample with accredited lab analysis at $80 to $250 and a surface swab or tape lift at $25 to $150. Rival Home Inspections prices an infrared thermal imaging moisture scan at $75 as an add-on, $150 as a full-home add-on and $450 as a standalone full-home inspection. Wright Restorations Canada prices post-remediation clearance testing at $200 to $600 per visit including lab work.

There is also a lab-direct route. Mold & Bacteria Consulting Laboratories in Mississauga sells a two-sample air testing package at $182 plus HST, including pump rental, cassettes and lab analysis, with results in three to five business days and extra samples at $60. That price buys laboratory numbers with no moisture investigation and no interpretation attached.

Every figure in this section prices mould sampling. The index publishes no equivalent figure for asbestos sampling from any source, so a homeowner planning demolition cannot use this site to budget one. Naming the gap is more useful than filling it with a guess. Comparable published numbers sit on the mould inspection cost page.

Where the inspection-listed companies sit on the map

Company density is uneven across the region. Islington-City Centre West holds 38 of the 294 listings, with an average rating of 4.83 across those 38. Burlington holds 25 listings, Willowdale 19, Don Mills 17, Markham and Oakville 15 each, Brampton 12, Mississauga 11, and Agincourt, Whitby and Oshawa 10 each. Their average ratings run 4.67 in Burlington, 4.79 in Willowdale, 4.90 in Don Mills, 4.67 in Markham, 4.83 in Oakville, 4.73 in Brampton, 4.72 in Mississauga, 4.88 in Agincourt, 4.41 in Whitby and 4.90 in Oshawa, each figure averaged only over the companies in that area that carry a rating, which in several of them is fewer than the number listed. Across the whole index, 277 of the 294 companies carry a rating, averaging 4.76 with a median of 5 and a range of 1 to 5. Those 277 companies hold 10,460 reviews between them, with a median of 19 per company and a maximum of 480.

Three of the ten inspection-listed companies sit in Brampton and two in Islington-City Centre West, which together account for half of that group. The rest are scattered one to an area. Fourteen of the 59 areas this site publishes hold no company based in them at all, including CityPlace, Corktown, East York, High Park, Leslieville, Liberty Village, Parkdale, Queen West, Riverdale and Rosedale. A homeowner in one of those 14 is looking at listings from a neighbouring area, and the index does not record travel range, so it cannot say who covers what. The companies filed for the flood side of this work are listed under water damage restoration, ordered by the RestorationIndex Score.

Frequently asked questions

Does this index tell me whether a company can test for asbestos?

Only indirectly. Thirteen of the 294 listed companies carry the Google Maps business label asbestos testing service and 14 are labelled environmental consultant. The site's own categories cover water, mould, fire and sewage work, so no listing page states what a company samples for. The record holds no licence, certification or scope-of-work field to check that against.

How much does tear-out cost in a flooded basement?

DeSa Contracting prices tear-out and removal of soaked materials, meaning drywall, carpet and insulation, at $500 to $3,000 per job in its Toronto guide. That sits beside emergency extraction at $500 to $3,000 and structural drying at $800 to $4,000 from the same guide. All three are quoted before 13% HST.

How many companies here do testing without a removal listing?

Ten. Those records appear under mould inspection and testing and in no removal category anywhere in the index. The other 49 companies in that category also hold a removal listing. The categories describe how each listing is filed on this site, not a company's business model, and nothing in the data confirms what work a firm turns down.

What does a mould inspection cost in Toronto?

A visual inspection with a written report runs $150 to $400 per visit per Restoration Mate. A package with two or three air or surface samples including lab analysis runs $350 to $770 per The Mold Guy. Post-remediation clearance testing runs $200 to $600 per Wright Restorations Canada. Add 13% HST to each.

Which companies here are listed for basement flood work?

Thirty-seven of the 294 carry the basement flood cleanup category, against 258 for water damage restoration and 200 for mould removal. That hub was merged into water damage restoration in August 2026, so those companies are listed there. The index reports the categories a listing was filed under and its Google rating and review count, and holds no completion data, warranty terms or response times for any of them.
