WHAT WE FIX

Basement Waterproofing Services in Wilmington, DE

Interior Basement Waterproofing

A perimeter drain under the slab carries water to a sump before it can pool on the floor. Works in finished and unfinished basements.

French Drain Installation

Interior and exterior French drains that relieve hydrostatic pressure along foundation walls and footings.

Sump Pump Installation & Replacement

Primary pumps, battery backups and high-water alarms, so a storm-night power outage does not mean a flooded basement.

BEYOND THE BASEMENT

Crawl Space & Foundation Services

Crawl Space Encapsulation

Sealed vapor barriers, drainage and dehumidification that end musty odors, damp insulation and soft subfloors.

Foundation Crack Repair

Injection and sealing for wall and floor cracks, plus a check for signs of bowing or settlement in older stone and block foundations.

Exterior Foundation Waterproofing

Excavation, membrane and drain tile on the outside of the wall, stopping water before it ever reaches the foundation.

Basement Waterproofing FAQs

Answers to the questions Wilmington homeowners ask most. Call [PHONE] for anything else.

How much does basement waterproofing cost in Wilmington, DE?

Most projects fall between [EDIT: $X and $Y]. Interior drains are priced by the linear foot, and exterior work costs more because it needs excavation. Your quote is always written and itemized.

Do I need interior or exterior waterproofing?

Interior drainage with a sump suits most older Wilmington homes and costs less. Exterior membranes make sense when there is room to dig along the wall or the foundation is being rebuilt.

What are the signs my basement needs waterproofing?

Water at the wall-floor joint after rain, white mineral stains, peeling paint, a musty smell, damp carpet or a sump pump that runs constantly.

Does homeowners insurance cover a wet basement in Delaware?

Standard policies usually exclude groundwater seepage and flooding but may cover a sudden pipe burst. Check your policy; we can document the cause of the water for your insurer.
