Crawl Space Repair
Crawl space repair starts with finding the cause of the problem. High humidity, standing water, mold, damaged insulation, sagging floors, and ventilation concerns do not all need the same fix.
Crawl Space Ninja evaluates the conditions under your home before recommending a repair plan. Through The Ninja Way process, we determine which repairs or moisture-control measures the crawl space actually needs.
Depending on the findings, that may involve humidity control, mold removal, insulation, water management, structural support, ventilation, or a combination of solutions.
Common Crawl Space Problems and Repair Options
Depending on the inspection findings, Crawl Space Ninja may address one or more of the following conditions.
High Humidity and Dehumidification
Adding more ventilation does not necessarily control high humidity. Depending on the conditions, a properly sized crawl space dehumidifier and a crawl space vapor barrier may be part of the moisture-control plan.
Mold and Wood Rot
Mold and wood decay in a crawl space can indicate that moisture conditions need to be addressed.
Effective crawl space mold removal should address the visible growth as well as the conditions that allow mold or wood decay to continue.
Crawl Space Insulation
The right crawl space insulation depends on how the crawl space is configured. Fiberglass may be appropriate in some spaces, while other insulation and air-sealing approaches may be better suited to different crawl-space conditions.
Standing Water
Standing water should be traced to its source before choosing a repair method. Depending on the conditions, a sump pump and interior drainage trench may be part of the solution.
If water is reaching the crawl space from outside, exterior drainage conditions may also need to be addressed.
Sagging Floors and Structural Support
Sagging floors can have several causes, including inadequate or deteriorated support in older homes.
A crawl space foundation repair evaluation can help determine whether additional floor supports or another structural repair is appropriate.
Soil Gases and Ventilation
Closing crawl space vents changes how air moves through the space. If soil-gas or radon concerns are present, ventilation should be considered as part of the overall crawl-space system.
A crawl space vent fan or a dedicated mitigation system may be appropriate depending on the conditions found.
