"excellent workers from first estimate to completed job. Estimator Demetrius Dotson very patient in inspecting what needed to be done and answering questions in a way I could understand. To do the job, workers Aaron and his brother Lyndonn kept us informed of arrival time and explained what they will be doing. Excellent work and even helped put back some items in to the garage (one was very heavy} in areas that would not affect the work done. Beyond expectations for me and I thank them all. "

Foundation, basement or crawlspace waterproofing / encapsulations FAQs

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
