Damp Crawl Spaces – Encapsulate and/or Ventilate? Or a combination of both?
With the spring rains approaching, homeowners with crawlspaces will start to notice that seasonal shift from low humidity to high humidity. Dew point levels will rise, air-conditioning units are turned on, and the entire dynamic inside crawlspaces changes.
Elevated Dew Points Result In Crawl Space Condensation Problems
Higher dew point levels translates into condensation buildup, elevated wood moisture levels, tagging insulation, and/or condensation drip. Within 4-6 weeks the right conditions exist for the development of mold and/or mildew on the crawl space floor system, duct work, and sub-structure. Many homeowners will spend thousands of dollars on foundation drainage improvements as well as expensive mold remediations with limited results in regards to achieving long term moisture control.
Crawl Space Tips
Foundation drains don’t solve crawlspace humidity and/or ventilation problems!
> Be sure to have your crawlspace inspected by a real crawlspace air quality Specialist that understands the dynamics of dew point and how crawl space ventilation problems begin in the first place.
> Be cautious of franchisees that only recommend expensive encapsulations.
> A true seasoned crawl space moisture mitigation company should have the resources to install encapsulations and/or controlled ventilation systems fired by a factor of dew point.
> Often, a hybrid system combining both approaches can be developed for a fraction of the cost of a traditional sealed crawl space system.
> When researching different companies don’t allow call centers to book appointments with you. Most call-center personnel have little to no construction field experience, and don’t even fully understand the problem when reported.
> Sales teams are poorly trained and commissioned based. They are taught high pressure closing tactics to solicit quick decisions and are trained to embellish the problem in an effort to scare customers into buying a more expensive systems.
> Not solving the problem. After the work, make sure the problem was solved.
> Ask to speak to someone in production and make your decision on whether or not they are qualified by the initial phone conversation.
> Ask specific questions about their experience, backgrounds, and credentials.
> If possible, have an independent non-commissioned based consultant evaluate the problem and develop a protocol.
The most important part of solving the challenge with a practical solution is diagnosing the problem correctly in the first place. For a list of independent consultants, professionals, mold hygienists and/or engineers, please don’t hesitate to contact us for a referral!
