What to know about Exterior waterproofing

Above ground, exterior waterproofing means keeping rain and meltwater out of the walls of the house and out of the structure under balconies and decks that sit over living space. Most wall leaks don't come through the middle of a wall. They come in at the details: around windows and doors, at pipes, vents and light fixtures, where a balcony or deck meets the house, and along parapets and wall tops, where water collects and wind pushes it inward.

What changes in Toronto

We list 4 areas inside Toronto on their own pages, because a service area is drawn by each pro and does not always reach the whole city. For exterior waterproofing, the part of town matters as much as the city.

Toronto is the principal city of a wider area we list under the name Greater Toronto Area, which takes in 27 other places. A pro's service area might be Toronto on its own or the whole of it — we match on the one they gave us.

Toronto publishes its own building-permit page, and it is linked below beside the rules that apply in Ontario. Whether exterior waterproofing needs a permit is answered there, not in a quote.

The rules we can source for this work in Ontario cover general contracting and renovation. They are set out below with the page each one came from — the regulator's words, not ours.

Toronto is in the Ontario and Quebec zone our seasonal checklists are written for, and this work appears in Summer and Winter on the maintenance calendar. Those notes are about heavy snow, freeze–thaw cycles and ice dams.

Exterior waterproofing costs in Toronto

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Size of the area and the height of the walls
  • Material chosen
  • Removal of the existing material
  • Repairs needed to what's underneath
  • Access, including ladders, scaffolding or lifts
  • Trim, corners and openings to work around

How to choose waterproofing contractors in Toronto

  • Choose a pro who works regularly with your material, whether that's siding, stucco, brick, eavestroughs or soffit and fascia.
  • Ask them to explain what's causing the problem, not only how they'll cover it up.
  • Get a written quote that separates removal, repairs to what's underneath and the new finish.
  • For chimney and masonry work, look for someone with specific masonry experience rather than a general handyman.
  • Check that they carry liability insurance, especially for work on ladders or scaffolding.

Questions to ask waterproofing contractors before you hire

  • What do you think is causing the damage, and will your work fix the cause?
  • Will you check the sheathing or wall underneath once the old material is off?
  • How will you handle water management, such as flashing, caulking and drainage?
  • Does this work need a permit from my municipality, and who will get it?
  • Can you show me proof of liability insurance?
  • What warranty do you offer on your workmanship?

Exterior waterproofing permits in Toronto

Some exterior waterproofing work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.

Common exterior waterproofing questions

Is LokalMatch free for homeowners?

Yes. You never pay LokalMatch to request quotes or talk to pros. Professionals pay a fee to connect with homeowners whose projects fit their business.

How many pros will contact me?

We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.

Do I have to hire someone?

No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
