Question 1

How do I know if my basement needs waterproofing?

Accepted Answer

Common signs include water stains or white mineral deposits (efflorescence) on walls, a musty smell, visible cracks in the foundation, peeling paint, rust stains, or actual standing water after rain. Even minor dampness should be addressed early — moisture damage compounds over time and can lead to mold, structural damage, and costly repairs.

Question 2

What is the difference between interior and exterior waterproofing?

Accepted Answer

Exterior waterproofing stops water at the source by applying a membrane to the outside of your foundation wall. Interior waterproofing (a French drain and sump pump) manages water that has already entered, redirecting it away from the living space. Both are effective — the right choice depends on your situation, soil conditions, and budget.

Question 3

How long does basement waterproofing last?

Accepted Answer

A professionally installed interior drainage system with a quality sump pump typically lasts 20–30 years. Exterior membrane systems can last 20+ years. We back all work with a written warranty.

Question 4

How much does basement waterproofing cost in BC?

Accepted Answer

Interior drainage systems typically range from $5,000–$15,000 for an average home. Exterior waterproofing can range higher depending on scope. We provide free, no-obligation written estimates so you know exactly what to expect.

Question 5

Are foundation cracks serious?

Accepted Answer

It depends on the type. Hairline vertical cracks from normal concrete curing are common and usually just need sealing. Horizontal cracks, stair-step cracks, or cracks wider than 1/4 inch can indicate structural movement and should be assessed immediately.

Question 6

What is polyurethane crack injection?

Accepted Answer

A low-viscosity polyurethane foam is injected under pressure into the crack, where it expands to fill the void completely and cures into a flexible, waterproof seal. It's fast, minimally invasive, and highly effective — done entirely from inside without excavation.

Question 7

How long does crack repair take?

Accepted Answer

Most residential crack injections are completed in a few hours. The polyurethane cures quickly and the area can typically be used the same day.

Question 8

Do I need deck waterproofing?

Accepted Answer

If your deck is above a garage, suite, or any interior space, waterproofing is essential. Signs you need it: water stains on the ceiling below the deck, soft or rotting wood, or a deteriorating existing coating.

Question 9

How long does a deck membrane last?

Accepted Answer

A properly installed deck membrane typically lasts 10–20 years. We recommend recoating the top wear coat every 5–7 years to maximize system lifespan.
