What We Do

The Full Scope of Our Union, SC Basement Waterproofing Work

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Basement

Interior Drain Tile

We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.

Basement

Sump Pump & Basin Installation

Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.

Basement

Wall Crack & Cove Joint Sealing

The cove joint where the floor meets the foundation wall is one of the most common Union, SC leak points, and we seal it as part of every interior system.

Basement

Vapor Barrier Wall Membrane

A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.

Basement

Window Well Drainage

Poor window well drainage is one of the most overlooked Union, SC basement leak sources, and it's often the cheapest fix on the list.

FAQ

What Union, SC Customers Ask Us Most About Basement Waterproofing

How much does interior drain tile installation cost?

Every Union, SC quote is itemized in writing so you can see exactly what drives the total.

Will you cut into my basement floor?

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

How long does basement waterproofing take?

Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.

Do I need a sump pump if I'm just sealing a crack?

Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.

Is basement waterproofing covered by insurance?

Coverage depends on your policy and the cause of the water intrusion — we can document conditions for a claim, but approval is up to your insurer.

Do you offer a warranty on basement waterproofing work?

Warranty terms are often transferable if you sell the property later.

Our Services in Union, SC

Both the city of Union and Union County received their names from the old Union Church that stood a short distance from the Monarch Mill. When it was first founded, the city of Union was known as Unionville; later the name was shortened to Union. The county's first white settlers came from Virginia in 1749. Union County's population grew the fastest between 1762 and the start of the Revolutionary War. Settlers built log cabins and cultivated tobacco, flax, corn and wheat. Union was one of the first towns settled in the area and was untouched during the Civil War because the Broad River flooded and turned Sherman’s troops away from the town.
