25 services, one crew and one claim. We handle the job from the first pump-out through to the drywall going back on.
Water Damage Restoration
Water damage gets worse by the hour.
Learn more
Flooded Basement Cleanup
A flooded basement is the most common water loss we attend in Toronto & the GTA.
Learn more
Sewer Backup Cleanup
Sewage backup is classed as Category 3 water, sometimes called black water.
Learn more
Burst & Frozen Pipes
A burst supply line at mains pressure can release hundreds of litres before anyone notices, and the damage is rarely limited to the room it happened in.
Learn more
Emergency Water Extraction
Extraction is the first hour of the job and it decides the cost of everything after it.
Learn more
Structural Drying & Dehumidification
Drying is the part of a water loss that gets rushed, and rushing it is why mould appears three weeks later in a basement someone thought was fixed.

How it works
What happens after you call
You call, we pick up
A person answers, whatever time it is. Tell us what you are seeing and we will tell you what to do first. We start dispatching while you are still on the phone.
We are there and we stop it
Usually within 45 minutes. We pump the water out, remove what cannot be saved and set air movers and dehumidifiers so the damage stops spreading.
We finish it and bill your insurer
Daily moisture readings until the materials reach dry standard, then the repairs. We document the loss the way adjusters want it and deal with them directly.
Why Delta24
Why property owners choose Delta24
A professional restoration contractor, certified to industry standard and trusted across the Greater Toronto Area.
24/7 Availability
Our lines are open every hour of every day, including weekends and public holidays. A certified technician is dispatched on the call rather than scheduled for the following morning.
Rapid Emergency Response
We are on site within 45 minutes anywhere in the Greater Toronto Area. Water reaches drywall and subfloor within hours, so how fast the first crew arrives decides the size of the job.
Proven Experience
Delta24 Restoration has restored residential and commercial property across Toronto and the GTA for 5 years. Every job is run by an experienced project manager from the first call to the final inspection.
IICRC Certified Specialists
Our technicians are certified by the IICRC in Water Damage Restoration and Applied Structural Drying, and we work to the S500 and S520 industry standards. WSIB cleared and fully insured.
Done Right, Start to Finish
We restore property to its pre-loss condition. One certified crew handles the job from extraction through to the final coat of paint, so nothing falls between trades.
Transparent, Approved Pricing
Clear price ranges published up front and a written scope before any work begins. We bill your insurance company directly, so in most cases the only amount you pay is your deductible.

Questions
Common questions
My basement is flooded. What should I do first?
Stay out of the water if it is near outlets, appliances or the electrical panel, and have the power cut first. If you smell gas, leave the house before calling. Photograph everything before you move it, and do not start pulling up carpet or cutting drywall until the loss is documented.
What will flooded basement cleanup cost me?
If the loss is covered, usually just your deductible. We bill your insurer directly and deal with the adjuster on your behalf. For uninsured work we provide a written quote before we start, and the fastest way to keep the cost down is to call early, because material that is dried in place does not have to be replaced.
Is a flooded basement covered by insurance?
It depends on the source. A burst pipe or failed appliance is normally covered. Water coming up through a floor drain is sewer backup, which is almost always a separate endorsement. Water entering from outside during heavy rain is overland flood, which is another endorsement again.
Can I clean up a flooded basement myself?
A small clean-water spill, sometimes. Anything involving sewage, water that has been sitting, or water that has reached drywall and insulation, no. A shop vacuum lifts surface water and leaves the rest inside the building, which is where mould starts.
Does the City of Toronto help with basement flooding?
Toronto runs a Basement Flooding Protection Subsidy Program offering up to $6,650 per property toward backwater valves, sump pumps and pipe capping for eligible single-family, duplex, triplex and fourplex homes. Check the current terms on toronto.ca before relying on the figure.
