Frequently Asked Questions
Frequently Asked Questions — Crawlspace
A basic vapor barrier is a plastic sheet on the ground to reduce moisture. Full encapsulation seals the entire crawlspace—floor, walls, vents—and adds insulation and dehumidification for complete moisture control.
Yes—most homeowners see 10–20% lower heating and cooling costs. The sealed barrier prevents cold floors in winter and heat gain in summer, improving comfort throughout your home.
It removes moisture (mold's food source) and seals entry points. Dehumidifiers keep humidity below 60%, and sealed vents block pest access.
We recommend one for Better+ packages. Once the space is sealed, a dehumidifier maintains 30–50% humidity year-round—essential in Mid-Michigan's humid climate.
Most projects take 2–4 days. Basic vapor barrier installations (Good) take 1–2 days. Full encapsulation with insulation and dehumidification (Better/Best) takes 3–4 days.
Yes—we can replace damaged insulation, treat mold, and improve drainage. We'll identify any issues during your free inspection and include them in your quote.
Very little. Check the dehumidifier monthly, inspect the vapor barrier annually for tears, and replace filters every 6–12 months. Our EP Protect+™ program handles servicing for you.
