Restoration notes
Page last updated: By The RestorationIndex Desk
Every piece here says something RestorationIndex can show its working for: what the index data holds and what it does not, what each phase of the work costs, and which Ontario endorsement pays when a basement floods. Every price traces to a named source, every count is computed from the dataset when the page is built, and nothing here is a recommendation of any company.
- 01What an after-hours callout adds to the billDesa Contracting's Toronto guide lists an after-hours emergency fee of $150 to $500 or more, and prices holiday or overnight response at $250 to $1,000. That is one way to bill the hour. Restoration Mate's cost page lists time and a half rates after hours, and Toronto plumbing guides add a dispatch fee, so ask which applies.Read it
- 02Electrical safety in a flooded basementToronto Hydro says not to enter a flooded basement unless you are sure the power is disconnected. The Electrical Safety Authority (ESA) says to stay out if the water is above the outlets, baseboard heaters or furnace, or near the panel, and to call the local electric utility to disconnect the power.Read it
- 03Mould or mold, and why Toronto firms differMould and mold are the same word for the same growth: mould is the Canadian and British spelling, mold the American one. Of the 294 company names in this index, 44 use mold as a word and five use mould, while Health Canada's guide spells it mould throughout its own text.Read it
- 04Water damage or mould: telling them apartWater damage is the wetting, and mould is what grows when the material stays wet. Health Canada's guide reads stains, peeling paint and warped wood as moisture signs, and growth or a musty, earthy smell as mould signs. It says to fix the water problem first, so the first call goes to whoever can stop and dry it.Read it
- 05Wet wood, rotten wood and mouldy woodWet, mouldy and rotten wood are three different problems with different triggers. The Canadian Wood Council calls wood dry at 19% moisture content or less and says decay can generally only start above fibre saturation, which averages around 28%. Mould is counted in hours: Desa Contracting's Toronto guide says it can start growing within 24 to 48 hours.Read it
- 06Choosing a basement flood crew in TorontoChoose a basement flooding service in Toronto by asking what the quote covers: cleanup only or the rebuild too, and which water category (clean, grey or black water) the crew has scoped. Only 37 of the 294 companies in this index carry the basement flood cleanup tag, and every one of them also carries water damage restoration.Read it
- 07Mildew or mould on a basement wallFor a homeowner, mildew and mould are one problem: Health Canada recommends cleaning up any visible mould regardless of type and sets no health-based exposure limit. What changes the job is the wall. Growth on painted concrete or block can be washed. Mouldy drywall and insulation often must be cut out, and tear-out plus rebuild carries most of the bill.Read it
- 08Picking your own contractor on a claimYes, an Ontario homeowner can pick the contractor on an insurance claim. The Insurance Bureau of Canada says you are not obligated to use a company your insurer recommends. What the choice changes is the paperwork. One Ontario restoration firm says most adjusters it sees want a line-item estimate rather than a lump sum, backed by photographs and moisture logs.Read it
- 09What has to be thrown out after sewageAnything porous that sewage touched and that cannot be dried has to go, from carpet to drywall. The Sewer and Drain, a Toronto firm, calls sewage Category 3 water and removes porous materials under the trade's IICRC standards. The City of Toronto says to discard any contaminated item that cannot be washed and disinfected.Read it
- 10What mould removal actually involvesA mould removal job in Toronto runs in six steps: assessment, containment under negative air, removal of porous material, cleaning of what stays, clearance testing and rebuild. Ontario licenses no one to do this work, so the order and the line items in a written quote are how a homeowner tells a full remediation from surface spraying.Read it
- 11Asbestos risk before a basement tear-outThis 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.Read it
- 12Clean, grey or black water in your basementWhere the water came from decides whether soaked material gets dried or thrown out. Toronto pricing follows that split closely. The Sewer and Drain quotes a Category 1 clean-water job at $2,500 to $4,000 and a Category 2 grey-water job at $4,000 to $6,500, while Desa Contracting prices sewage backup (black water) at $5,000 to $30,000 or more.Read it
- 13How restoration work is actually pricedToronto restoration work is billed three ways: a rate per square foot of affected area, a charge per day of drying equipment on site, and a flat tier for a whole job class. The same basement lands in a different band under each, which is why two quotes can be far apart and both be arithmetic.Read it
- 14What drying equipment rents for in the GTAA self-managed dry-out is priced by the day. A Dri-Eaz dehumidifier rents for $59.99 to $89.99 per day from DryingEquipment.ca in Toronto, a 500 CFM HEPA air scrubber for $84.99 per day from Drying Equipment Rental in the GTA, and a HEPA vacuum for $80 per day from Simplex Equipment Rental.Read it
- 15Why two quotes for one basement differ so muchTwo quotes for one basement usually price two different jobs. CPR24 Restoration says Toronto cleanup companies usually charge $4.88 to $5.57 per square foot for standard removal and $13.93 to $41.80 for full service, and Ultimate Mold Crew puts professional remediation with air filtration and post-removal cleaning at $10 to $30. The gap is a difference in scope definitions.Read it
- 16Black mould versus everything elseBlack mould refers to a colour and, loosely, to one genus. Health Canada does not set a safe exposure level for any mould and advises removing indoor growth regardless of species. Identifying the species adds $100-$200 to an inspection, per Mold Inspection Canada, and CPR24 Restoration prices black mould removal at $1,393 to $6,270.Read it
- 17Burst pipes in a GTA winterA standard Ontario policy covers burst pipes, appliance ruptures and ice damming, according to the Insurance Bureau of Canada. It does not cover sewer backup or overland flooding. With 258 of the 294 companies in this index filed for water damage restoration, the deductible is the main limit in a winter loss.Read it
- 18Cleaning soot after a small house fireLeave the soot alone until the written scope is prepared. Air out the space, photograph all surfaces, and call the insurer before doing anything else. Rubbing oily soot into drywall or upholstery makes the professional cleaning bill higher. Of the 294 companies in this index, 78 list fire and smoke work but only nine carry Google's fire damage restoration label, so most fire calls go to the fire division of a water damage firm.Read it
- 19Does Ontario insurance cover a flooded basement?Coverage is not automatic. A standard Ontario home policy covers sudden, accidental water that originates inside the building. Water that backs up through drains or a sump requires the optional sewer backup endorsement, and rain or snowmelt that enters from outside requires the optional overland water coverage. These are two separate products with two separate prices; choose the wrong one and the loss will not be covered.Read it
- 20Hiring a mould removal company in TorontoTwo hundred of the 294 companies in this index provide mould removal in the Toronto area, and 175 of those also include water damage restoration. Since mould develops where moisture accumulates, the inclusion of water damage restoration tells you whether a single contractor can remove the growth and repair whatever kept the wall wet.Read it
- 21How long a basement dry-out really takesThree to five days of equipment time is the band Restoration Professionals publishes for structural drying in Toronto, while the rebuild afterward depends on scope, and Desa Contracting's guide says repairs can take one to three weeks. This index lists no job timeline for any of its 294 companies, so the answer here is derived from equipment-day pricing, not from anyone's promise.Read it
- 22A musty smell with no mould in sightAccording to Health Canada, air testing is generally not recommended, because an air test does not provide information that can predict health effects and often offers little information on the cause of mould damage in the house. The exception is a smell with no visible signs; an inspection then determines what happens next. The index includes 294 companies, and 59 of them list mould inspection and testing.Read it
- 23Ontario licenses nobody for mould removalOntario issues no provincial licence for mould remediation. All 294 companies in this index can lawfully call themselves mould experts, and the record does not show whether any of them has training. The credentials that do exist are voluntary, granted by industry bodies rather than the province, and this index does not record them.Read it
- 24Sewer backup or overland water coverageOntario offers two separate endorsements, each with its own trigger. Sewer backup pays for water that comes up through drains or for a sump that fails. Overland water pays for rain or snowmelt that enters above grade. Mitch Insurance Brokers reports that sewer backup costs $20-$250 a year, and isure reports that overland water costs $10-$30 a month. A base policy includes neither.Read it
- 25Stopping mould after the water is goneDesa Contracting's Toronto guide says mould can start growing within 24 to 48 hours of a flood, so the drying stage is the deciding factor in whether a water job stays a water job. In this index, 175 of the 294 companies list both water damage restoration and mould removal. At that overlap, one bill ends and another begins.Read it
- 26How to tell a restoration company from a lead resellerFifteen records were cut from this index after every website they published was fetched. Here are the three patterns that gave them away.Read it
- 27The first six hours after a basement floodThe order matters more than the speed. Doing these in the wrong sequence is what turns a cleanup into a rebuild, or a covered claim into a denied one.Read it
- 28What 294 GTA restoration companies actually look likeEvery figure here is computed from the July 2026 dataset when this page is built, so it cannot drift from what the rest of the site publishes.Read it
