Basements

Keep the Basement Dry

Water is one of the biggest threats to your home's foundation. Damp floors and walls, white chalky efflorescence on concrete or block, cracks, a musty smell or peeling paint on basement walls all mean moisture is moving through the foundation, and every heavy rain makes it worse.

We start by finding where and why the water is getting in. Then we explain the right fix in plain terms, with a free written estimate.

Exterior waterproofing stops water before it reaches the walls. We excavate along the foundation, clean and repair the cracks and apply a waterproofing membrane.

Then we install drainage, backfill and grade the soil so surface water runs away from the house.

Where digging is not practical, interior systems manage the water instead: waterproof coatings and sealants, French drains along the foundation and sump pumps that clear collected water automatically. We also repair wall and floor cracks and leaks around pipes, and check whether a crack comes from settling or structural movement.

Waterproofing Methods

Ways We Keep Water Out

Every basement is different. After the inspection we recommend the method, or combination, that suits your home.

  • Exterior Waterproofing

    A membrane and drainage on the outside of the foundation stop water before it reaches the walls. The most complete fix where the walls can be excavated.

  • Interior Coatings & Sealants

    Waterproof coatings on the inside walls and floor, a lower-cost option where digging outside is not practical.

  • French Drains

    A drain along the foundation collects water and carries it away before it builds up against the walls or under the floor.

  • Sump Pumps

    Clear collected water automatically, protecting the basement during heavy rain.

  • Crack & Leak Repair

    Cracks in walls and floors and leaks around pipes sealed, with a check on whether a crack comes from settling or structural movement.

  • Crawl Space Repairs

    Moisture, rot and damaged supports repaired to keep the crawl space dry and the floor above sound.

Common Questions

Basement Waterproofing Questions

Why is my basement wet?

Water gets in through cracks, along the joint between wall and floor, or from water collecting against the outside of the foundation. Finding which one is the first step, which is why every job starts with an inspection.

What are the signs my foundation needs waterproofing?

Water or dampness on basement floors or walls, white chalky efflorescence on concrete or block, cracks in the walls or floor, a musty smell or mold, and peeling or bubbling paint on basement walls.

How long does exterior waterproofing take?

Many projects are finished within a few days, depending on how many walls need treating, how deep the foundation is and the access around your home. We confirm the timeline with your free written estimate.

Will you need to dig up my yard?

Exterior waterproofing means excavating beside the affected walls, so plants in that area may need moving. We plan access with you in advance and leave the area clean and graded when we finish.

Is it worth waterproofing if the basement only leaks in heavy rain?

Yes. An occasional leak shows water has already found a way in, and repeated wetting weakens concrete, damages belongings and encourages mold. Fixing it early usually costs less than repairing the damage later.

Can waterproofing be done in winter?

Interior waterproofing, crack repair and sump pump installation can be done year-round. Exterior work depends on ground conditions, so we schedule excavation when the soil is not frozen.
