We only believe in solving your crawl space issues right the first time. We often run across crawl spaces with a sump pump but not encapsulation. Yes, this makes sure that any water that collects in the crawl space gets pumped out but it doesn't solve the issue of moisture and humidity. We came out and helped this person to get encapsulation and make sure there are very low moisture and humidity in their crawl space!

Hello, You did a great job on our rental house last year and want to do the same on our main house. Noticed that the soil is damp which is unusual, and i have had a plumber out with tools to cover off that their isnt any leaks from the plumbing. Could you guys figure out what is causing it as well as the vapor barrier? Thank you!

Project Location: Saint Helena, CA
Our home was built in 2000 and from the start our hard wood floors cupped. I'm planning on getting them redone but I'm told I should put down a moisture barrier first so I'm looking for a quote for that. The crawl space is about 2 1/2 to 3 feet with plenty of vents but always damp.

We have one existing sump pump in our crawl space. We are remodeling our kitchen, and in that process our kitchen remodeling contractor thought we might need another sump pump or other crawl space work and recommended that we talk with you.
