What’s Going On With Your Chimney?
Pick the one that sounds like yours. Every one starts the same way: a free inspection, with photos.
Haven’t Had Your Chimney Cleaned?
Soot and creosote build up every time you burn wood. If it’s been a year or more — or you don’t know — start with a sweep and a look inside.
Chimney CleaningSeeing Cracks Or Loose Bricks?
Open mortar joints, a cracked crown or brick flaking off all let water in. Caught early, it’s usually a repair, not a rebuild.
Chimney RepairWater Coming In?
Stains near the fireplace, water in the firebox or a damp attic around the chimney usually point to the flashing, the crown or the cap.
Flashing & WaterproofingSmoke Or Draft Problems?
Smoke coming back into the room means something is in the way — buildup, a blockage or a liner problem. A camera inspection shows which.
Chimney InspectionBuying A Home?
Have the chimney looked at before your conditions date. You get photos and a plain explanation of what you are buying.
Chimney InspectionNeed A Chimney Cap?
An open flue lets in rain, snow, leaves and animals. A cap measured to your flue keeps them out.

Two prices we can publish, and one we can’t — because nobody can price a repair honestly without seeing the chimney first.

Questions Homeowners Ask Before They Call
Straight answers. Anything else, call (416) 505-6228.
Are you WETT-certified?
Yes. The work is carried out by a WETT-certified technician — the certification Canadian insurers and home inspectors ask about.
Will the sweep make a mess in my house?
No. Floors and the fireplace area are covered before any tool comes out, the vacuum runs the whole time we sweep, and the area is left the way we found it — or cleaner. That is step one of every visit, not an extra.
Is the inspection really free, or is there a catch?
It is free. A technician comes to your home, works through the 19-point check and gives you the price on the spot. If you decide not to go ahead, you pay nothing and you still have the photos and the report.
Will you try to sell me a repair I don’t need?
No. If something doesn’t need fixing, we say so, and if it can wait, we tell you that too. You see the photos of whatever we do recommend, so you are not taking our word for it.
Do you work Saturdays and Sundays?
Yes. We work every day, 7:00–22:00, weekends included — at the same price as a weekday.
How long does a sweep take?
It depends on the chimney’s condition and access. We give you a realistic window when we confirm the booking, and we stay until it is done properly.
What if you find something during the sweep?
We show you the photos, explain what it means, and give you a price for the repair. What happens next is your call — the sweep is still $200 either way.
What happens during the inspection?
We cover the area around the fireplace, check the firebox, damper and smoke chamber, look inside the flue with a camera, and check the cap, crown, brick and flashing from the roof. Then we show you the photos and explain what we found.
Do I get photos?
Yes. Every issue we find is photographed, so you see exactly what we see. The photos are yours to keep.
Do I have to approve repairs right away?
No. You get the price at the inspection, and nothing starts without your OK. If you want time to think it over, that is fine.
How much does chimney cleaning cost?
This winter, a standard chimney sweep is $200, with the inspection included. Chimneys differ, so we confirm the price for yours before booking. How we price the work.
How much does chimney repair cost?
It depends on what is damaged and how the chimney is reached, so we don’t publish blind numbers. The inspection is free, and you get the exact price at your home before any work begins.
How often should I clean my chimney?
Most wood-burning chimneys benefit from a yearly cleaning, but it depends on how much you burn, what you burn, and the chimney’s condition. After seeing yours, we’ll recommend an honest schedule — sometimes that means less often, not more.
Can you inspect a chimney before I buy a home?
Yes. Tell us your timeline and we’ll do our best to fit the visit before your conditions date. You get photos and a written summary. If your lender or insurer asks for a specific type of report, check what they require first, so we can tell you whether ours fits.
Can you repair cracked brick and mortar?
Yes. Repointing (tuckpointing), brick replacement, crown repair and rebuilds above the roofline — matched as closely as possible to your home’s existing brick.
Do you install chimney caps?
Yes. Caps keep water, animals and debris out of the flue, and they are sized to your specific flue — not one-size-fits-all.
Is the work covered by a warranty?
Yes. Every job carries a warranty on both the materials we use and the labour. If something we installed fails, we come back and put it right.
How quickly can you come?
It depends on the season and your area. We work every day, 7:00–22:00. Call (416) 505-6228 or send the form and we’ll give you the earliest real time we have.
What areas do you serve?
Toronto, York, East York, North York, Scarborough, Etobicoke, Mississauga, Brampton, Vaughan, Concord, Thornhill, Richmond Hill and Markham. Not sure about your street? Call and ask.
