Common signs include water stains or damp patches on basement walls or floors, a musty smell that won't go away, visible cracks in your foundation, efflorescence (white chalky residue on concrete), or pooling water after heavy rain. Even if you haven't seen standing water, persistent humidity in your basement is a warning sign worth acting on. The earlier you address it, the less costly the fix.
Exterior waterproofing addresses the problem at the source — we excavate around your foundation and apply a waterproof membrane to block water before it ever reaches your walls. It's the most comprehensive solution but involves more labour and excavation.
Interior waterproofing manages water that has already entered or is pressing through the foundation, using drainage systems, sump pumps, and crack injections to redirect and remove it. Both approaches are effective depending on your situation, and in many cases we recommend a combination of the two.
Most residential waterproofing projects are completed within 1 to 3 days, depending on the size of the area and the methods required. Interior drainage and crack injection work can often be done in a single day. Exterior foundation waterproofing that requires excavation generally takes 2 to 3 days. We'll give you a clear timeline during your free quote so there are no surprises.
Yes — a dry, properly waterproofed basement is a strong selling point for any property. It protects your home from structural damage, prevents mould growth, and makes the space usable year-round. Many buyers and home inspectors flag moisture issues as red flags, so addressing it proactively protects both your home's value and your asking price if you ever decide to sell.
Yes. Crawl space encapsulation is one of our core waterproofing services. An unsealed crawl space is one of the most overlooked sources of moisture, mould, and air quality issues in a home. We seal the floors and walls with a heavy-duty vapour barrier and ensure proper ventilation so the space stays dry year-round. This also helps reduce heating and cooling costs by eliminating damp air from beneath your living areas.
Don’t wait for the next heavy rain to find out where your basement is vulnerable. Whether you’re dealing with an active leak, noticing early warning signs, or simply want peace of mind, Jecko Contracting is ready to help. Get in touch and we’ll assess your property, walk you through the right solution, and provide a free, no-obligation quote — fast.
