Our Crawl Space Work in Northwest Arkansas

Homeowner experiencing musty odors throughout the house and elevated indoor humidity year-round. Original vapor barrier was thin poly, partially torn and no longer providing meaningful protection.

Removed original vapor barrier material. Installed interior drainage channel along the perimeter. Added sump basin and pump. Installed full encapsulation liner on floor and walls with sealed seams and penetrations. Added crawl space dehumidifier.

Recurring standing water after spring rain events. Water intrusion through foundation wall-floor junction. Home on a low lot with drainage that directed water toward the foundation.

Installed interior perimeter drainage channel. Installed sump basin and submersible pump with discharge routed to slope away from foundation. Addressed wall-floor junction sealing. Inspected and addressed downspout extensions as a contributing factor.

Home built in the 1970s with original thin poly sheeting — much of it torn, shifted, and providing minimal coverage. High indoor humidity and musty odors, particularly in winter.

Removed original vapor barrier. Installed heavy-duty reinforced liner across crawl space floor and up foundation walls with properly sealed seams. Homeowner also had a crawl space dehumidifier added to manage residual humidity.

Older craftsman-style home with no vapor barrier on bare dirt floor. Significant musty odors, soft flooring in one area, and visible mold-like conditions on floor joists. Homeowner had deferred crawl space maintenance for years.

Thorough inspection to assess scope. Installed drainage channel and sump pump first (seasonal water intrusion from groundwater). After confirming drainage was functioning, installed full encapsulation liner with wall coverage and sealed penetrations. Crawl space dehumidifier added for ongoing management.

Home built within the past 10 years. Original builder-installed vapor barrier was thin, minimally overlapped, and not sealed. Homeowner noticed musty smell and humidity issues sooner than expected for a newer home.

Removed original thin barrier. Installed heavy-duty reinforced vapor barrier with properly sealed seams and wall coverage. Added crawl space dehumidifier. Inspection confirmed no standing water issues — encapsulation and humidity management appropriate for this space.

Homeowner on a lakeside lot experiencing seasonal groundwater intrusion. Existing vapor barrier was intact but water was accumulating under the barrier during spring months.

Installed sump basin at low point of crawl space. Installed submersible pump with float switch. Routed discharge line to gravity outlet away from foundation. Assessment confirmed encapsulation and updated vapor barrier would be appropriate follow-on work.
