Foundation, basement or crawlspace waterproofing / encapsulations FAQs
Cleaning your crawl space is a worthwhile investment for several important reasons. A properly maintained crawl space prevents structural damage by eliminating moisture that can deteriorate wood supports and metal components. It also significantly improves your home's indoor air quality by removing allergens like mold spores and pest droppings that can circulate through your living spaces.
Additionally, a clean crawl space contributes to better energy efficiency by allowing proper insulation installation and reducing humidity levels that force your HVAC system to work harder.
Several warning signs indicate your crawl space needs professional attention. Look for musty odors throughout your home, unexplained increases in allergy symptoms, higher energy bills, visible pest activity, or moisture issues.
Other indicators include sagging floors, warped wood, visible mold growth, standing water, or damaged insulation. If your crawl space hasn't been inspected in over a year, or if you've recently experienced flooding or severe weather, it's advisable to have professionals assess the space even without obvious symptoms.
Most crawl space cleaning projects take between one and three days to complete, depending on several factors. Simple debris removal in a small, relatively clean space might be finished in a single day.
More involved projects that include mold remediation, water damage repair, or pest control require two to three days. For large crawl spaces or those with extensive contamination, the timeline might extend to a week, particularly if additional services like encapsulation are included in the project scope.
You can remain in your home during basic crawl space cleaning. However, if the project involves mold remediation or pest extermination with chemical treatments, temporary relocation might be recommended, especially for household members with respiratory conditions or chemical sensitivities.
Professional cleaning companies use containment procedures to minimize the spread of dust and contaminants into living spaces, but some disruption is inevitable. Discuss your specific situation with your service provider to determine the best approach for your family's needs.
