Frequently Asked Questions — Foundation & Waterproofing in Grimsby

Why does my Ontario basement leak?›
Most Ontario basement leaks come from hydrostatic pressure in clay soil, deteriorated weeping tile or foundation cracks caused by freeze-thaw cycles. We diagnose the source before recommending a solution.
Interior or exterior waterproofing — which is better?›
Both work in different scenarios. Exterior is more comprehensive but requires excavation. Interior drainage is less disruptive. We recommend the right approach after a free on-site inspection.
Do foundation repairs require a permit in Ontario?›
Most waterproofing jobs don't need a permit, but structural or excavation work might. We identify permit requirements upfront and handle the paperwork.
How long does basement waterproofing last?›
Quality waterproofing is a long-term fix. We warranty our work in writing — ask us for warranty terms when we provide your estimate.
Does my home insurance cover foundation leaks?›
Coverage depends on your policy. Sudden events like a burst pipe may be covered; gradual seepage usually isn't. We provide inspection reports that insurers accept.
How quickly can you get to my home?›
Same-day availability is our goal. Emergencies get immediate priority dispatch; for non-urgent work we typically book within 24 hours.
Is there a service-call or inspection fee?›
No service-call fee. Our technician visits, assesses the problem and gives you an upfront price at no cost. Work starts only once you approve.
