Identifying Foundation and Basement Problems In Your Home

Basement Problems
Top of foundation
Water seeping in over the
foundation will often leave a trail
of water stains down the
foundation wall. Solution
Grading problems
Poor yard grading and drainage can cause water to pool up next to your foundation walls. Solution
Pipe foundation

The area where the pipe leaves the home through the wall could have a weak seal that lets water seep inside.

Solution

Leaking mortar joint

Mortar joints become weak over time and start to let water drip into the home and down the walls to the floor.

Solution

Sump pump
A sump pump can be used to control basement leaks and flooding. It pushes water out and away from the home. Solution
Mold & mildew

Mold and mildew grow whenever moisture, excessive humidity, and organic materials are present inside of the basement environment.

Solution

Wet floor cracks
Floor cracks will eventually let water seep into the home when the water table outside the foundation rises or falls. Solution
Floor drain
A floor drain often becomes clogged with dirt and debris, and it is also not uncommon for tree roots to grow them and obstruct the flow of water. Solution
Cove seepage

A rising and falling water table outside of the home can cause water to be pushed through the cove joint (where the wall meets the floor).

Solution

Porous concrete
Concrete can become brittle and weak over time if it wasn't poured correctly, and this can make it very easy for water to get inside Solution
Efflorescence

This is typically a white, flaky, and chalky substance that can be seen on basement walls or floors. It is a sign that moisture is present.

Solution

Foundation wall cracks
Wall cracks could be an indication of an underlying structural problem. They must be filled and sealed before water starts to seep through them. Solution
Leaky basement window wells

When the window well drain is clogged, water will push up against the basement windows until it breaks through the frame's seal.

All Seasons found a crack in our basement foundation and installed an interior pressure relief drain. Kirk was very professional and thorough in investigating our issue and proposed a clear solution and estimate. Their crew was efficient, courteous, and responsive to our concerns. We have full confidence in the solution thanks to All Seasons' work and guarantee. We would recommend All Seasons to anyone and would hire them again (although we hope we don't have to)!

I called All Seasons about my trench drains and drywell. The owner was so kind and helpful. He sent David to come and assess everything. I got great advice on how to maintain the drywell and help cleaning the drains. They are decent, caring, honest people and I am very grateful. I highly recommend All Seasons.

We recently used All-Seasons Waterproofing on our job and they were great. From the initial visit with their estimator to the final install they were great to work with. They communicated really well and knew their craft. I would definitely recommend them for your waterproofing needs.
