A damp crawl space can affect the air in the whole house. Tell us what you are noticing and one crawl space specialist will contact you to inspect and talk through options.

About crawl spaces
Is encapsulation necessary?
It depends on moisture, ventilation and condition. An inspection can tell.
Can I look myself?
You can look if it is safe, but a professional can assess hidden problems. Do not enter if you are unsure.
Will several contractors call me?
No. Only one contractor will ever call about your request. You will not get a pile of calls and constant emails, and we never sell your information.
Who does the work?
A licensed, independent, insured and vetted partner contractor visits to assess the work, gives you an estimate and does the work if you decide to go ahead. See our Terms of Use for details.
