Working in Saint John
Heavy rain, wet soil and repeated freeze-thaw keep foundations under water pressure for long periods. Ask about drainage tile condition, sump capacity and grading, and plan exterior membranes for a dry stretch so the trench does not fill while the wall is open.
New Brunswick's economy is anchored by forestry, IT services in Fredericton-Moncton, and Saint John's deep-water port, with humid-continental winters and short, mild summers.

Email us your city, the service you think you need, and what you are seeing. A specialist who works in your area follows up to set up an assessment. Requesting a quote is free and there is no obligation to go ahead.
Is every foundation crack a problem?
No. Thin vertical or slightly diagonal shrinkage cracks in poured concrete are common and are often cosmetic. Cracks that leak, keep widening, run horizontally, follow a stair-step pattern in block walls, or have one side offset from the other deserve an assessment. Our blog has a full guide to crack types.
Should I waterproof from the inside or the outside?
Interior drainage with a sump pump manages water that reaches the wall. It is usually less disruptive and costs less. Exterior excavation with a membrane and new weeping tile stops water at the source, but it means digging around the house. The right choice depends on access, how much water you get, and the state of your existing drainage.
How much does foundation repair cost?
It varies a lot. Injecting one crack is a small job, while underpinning or full exterior waterproofing is a major project that can reach five figures. The price depends on the method, the length of wall or number of piers, excavation depth and access, soil conditions, permits, and what has to be restored afterward. The only reliable number is a written quote after an on-site assessment.
