"My experience was excellent, from initial call to completion of the work. Great team that showed up on time, conducted themselves well, and were committed to their work. Austin F. Conducted a thorough inspection and proposed a multistage plan to repair my crawlspace. I was especially happy that an engineering firm prepared final inspection and drawings for the county permit process. John, Austin, Taylor, and Chris worked very hard for three days, even in the rain and cold. Great company and people."

Basement Waterproofing questions, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.
