Foundation Repair Quotes in Montreal

Your foundation is the base of your entire home, and problems affecting it should never be ignored. In Montreal and surrounding areas, freeze-thaw cycles, clay soils in some neighbourhoods and spring snowmelt put constant pressure on foundation walls. The result can be cracks, basement water infiltration, a clogged French drain or settling.

Many homes in the region are several decades old and still have their original French drain, which may have reached the end of its useful life. A proper diagnosis helps tell a minor shrinkage crack apart from a structural issue that calls for more extensive work.

What affects the price

Every foundation is different, and cost depends mostly on the diagnosis. Prices also vary by area, materials, scope of work, access and season:

• The nature and severity of the problem: an isolated crack or a structural issue
• The number of cracks and where they are
• Repair method: interior repair or exterior excavation
• Length of French drain to replace and excavation depth
• Site access: semi-detached home, narrow driveway, landscaping to move
• Soil type and presence of water
• Restoring the yard, asphalt or pavers afterwards
• Time of year and crew availability

To compare foundation repair quotes, make sure they are based on a similar diagnosis. An interior repair may be enough for an isolated crack, while a failing French drain often requires exterior excavation. A much lower quote may simply address a different problem or exclude restoring your yard, driveway or landscaping once the work is done.

How to choose a contractor

Foundation work affects the structure of your home. Before you sign, check the following:

• RBQ licence: the contractor must hold a valid licence from the Régie du bâtiment du Québec for this type of work.
• Liability insurance: ask for proof of valid civil liability insurance, which is essential for excavation work.
• Written, detailed quote: it should describe the diagnosis, method, materials, site restoration and warranty offered.
• Warranty: read the contractor’s warranty terms carefully. If your home is a new build, ask about possible coverage under the Garantie de construction résidentielle (GCR).
• Reviews: read customer reviews and ask for references.
• Payment: never pay the full amount upfront. A payment schedule tied to progress is safer.

Tips for foundation work

• Act quickly: a small crack that lets water in can get worse with frost. It is better to have it assessed early.
• Plan around the season: excavation is easier when the ground is not frozen. Request quotes before the busy season to get better dates.
• Document the problem: take photos of cracks and note when water appears. This helps the contractor make an accurate diagnosis.
• Check permits: some work requires a permit from your municipality, such as excavation or drain connections. Check with your city.
• Compare the diagnoses: if quotes propose very different solutions, ask each contractor to explain their approach.

Keep every document related to the work, including the quote, invoices, photos and warranty. They will be useful if a problem comes back and can reassure a future buyer when you sell your home.

Frequently asked questions

Is a crack in my foundation serious?

Not always, since some shrinkage cracks are only superficial. A crack that lets water in or keeps widening should be assessed by a qualified contractor.

How do I know if my French drain needs replacing?

Water at the base of basement walls, persistent dampness or iron ochre are common signs. A camera inspection can confirm the drain's condition.

Do I need a permit for foundation work?

Some work, such as excavation or drain connections, may require a municipal permit. Check with your city.

How many quotes will I receive?

We send your request to up to 4 contractors in your area. The number of quotes depends on their availability and your project.
