7 Signs you may have water entering your Basement

Inspect baseboards, lower sections of drywall and other building materials close to the floor. If they are discolored, smell musty or swelled in size then it was likely caused by water.

A musty smell is commonly caused by mold & mildew growth due to moisture, so if it smells musty then there is a good chance you have water entering your basement. 

These cracks are often easily identifiable, particularly if flooring or drywall isn’t obstructing your view of the foundation wall. Cracks in foundations typically do not cause structural concern but will eventually allow water to seep through.

Finding the cause of condensation on basement windows can be tricky. It’s usually due to either poor ventilation or too much moisture. If ventilation isn’t the problem, high humidity from water leaks is likely the main cause.

A white powdery substance is commonly observed near floor level or along cracks in the flooring or foundation.

Mold and mildew, thrive on moisture and often appear on surfaces like walls & ceilings. Mold can begin forming in as little as 24-48hrs reproduce through spores that can float in the air and land on damp areasWhile mold has a fuzzy or textured appearance and can be various colors, mildew is typically a flat, powdery coating and appears as gray, white, or light brown. 

New or lingering symptoms when your in the home could potentially be caused by unhealthy air circulating through the home.

Understanding Our Process

Before we begin

Before repairs can commence our team will verify that all walls to be waterproofed are accessible, your belongings protected & our ventilation systems to collect dust are in place.

Excavation

A1’s exterior process involves excavating along your foundation down to the footing so that your foundation walls are fully accessible.
Upon completion of the excavation, all foundation walls are thoroughly cleared of any dirt and debris, and any cracks are repaired.

Waterproofing Application

Once the wall preparation is complete, we apply liquid membrane which cures to form a tough flexible membrane, which will serve as a base for the application of the 56 mil thick layer of polymeric waterproofing sheet membrane which is applied over the liquid membrane.

Weeping Tile

Next we will remove & dispose of your old weeping tile system (if present) & install a new weeping tile to ensure this critical aspect of the waterproofing process is functioning optimally.

Additional Waterproofing

Backfill & Grading

Backfilling & grading is the final step & we make sure to do this in a way that limits the amount of settlement youll experience afterwards. If there were things that had to be removed due to the excavation we will gladly place everything back as best as possible. Once the repair area has had ample time to settle we will return to do any final regrading free of charge.

Protect Your Basement Smarter with an Exterior Sump Pump System

If you’re waterproofing your home from the outside, don’t make the mistake of relying on an interior sump pump. Why let water enter your basement only to pump it back out? Our exterior sump pump system captures water before it ever reaches your foundation — keeping your basement drier, cleaner, and better protected.

Unlike interior systems, our exterior sump pumps:

  • Stops water before it gets inside — no moisture inside your home

  • Takes up zero space inside your basement

  • Sits flush with the ground — out of sight, out of the way

  • Is virtually maintenance-free and built to last


Upgrade to an exterior sump pump system — your basement will thank you.

How much can you expect to pay???

When quoting an exterior waterproofing repair there are many factors to consider when pricing takes place.

Things such as proximity to other homes or obstacles, underground services such as gas or hydro & soil type to mention a few.

Interior waterproofing is cheaper and sometimes less evasive but unlike exterior waterproofing, which prevents water from coming in contact with the foundation it acts as a corrective method that manages water that has already entered a basement.

Cost typically range between $60 and $120 per linear foot. 

When we repair foundation cracks, we don’t mess around, upholding a rigorous standard of quality in our crack repair services. Whether performed by hand on the exterior of the home or done from the inside, we guarantee results or your repair cost is fully refunded.

Interior Vertical Crack Repairs range from $600 – $800

Exterior Vertical Crack Repairs range from $1,200 +
