Before this project began, the homeowner was dealing with mold from a damp crawlspace. The mold was having a negative effect on their asthma symptoms, and they wanted to fix the problem permanently. Our crew installed our crawlspace drainage channel at the perimeter with a sump pump. We then used CleanSpace to encapsulate the area and control the environment while preventing moisture and mold growth with our SaniDry Sedona dehumdifier. The result was a drastically safer home, protected and dry for years to come.

We installed our SaniDry Sedona dehumidifier to complete the encapsulation of this crawl space. The SaniDry is highly recommended to control humidity and purify the air of moisture and mold contaminants.

The SuperSump Plus system is connected to a discharge line, where water goes out through to a discrete LawnScape Outlet away from the home.

Underneath the CleanSpace, we put in the drainage matting. This will serve as a channel for moisture under the vapor barrier.

Job Stories From Friday Harbor, WA
Groundwater Seepage in Friday Harbor, WA Crawlspace

During our initial inspection of Michael’s Friday Harbor, WA, farmhouse, Rainy Day discovered groundwater seepage, mold, condensation, and pests in his crawlspace. We came to the home and got right to work with installing a new drainage system and crawlspace encapsulation system. A new three-in-one TripleSafe sump pump was also installed. We sealed all entries with vent covers and then added the SaniDry Sedona dehumidifier. Now, all of Michael’s moisture issues are simply a thing of the past.


Whether you are up north in Friday Harbor, or down south in Edmonds, we offer free inspections and estimates for all your waterproofing needs under the home. Call us today to schedule at 1-833-988-3570

Need foundation evaluation--we have some cracks in our ceilings.
Vicinity of Madden Lane in Friday Harbor
Our house was built in 1935 and has a crawlspace foundation. Since the last heavy snow (and a few small earthquakes we had), we have noticed cracks in the ceiling in some rooms and a widening of the spaces between some planks on the hardwood floor. We would love to get a quote and schedule a repair! Thank you!

Weatherize small (2 bed/1 ba) cabin to improve moisture control, energy consumption, and rodent issues: Clean crawl space, air seal & insulate floor, "rodent-proof" skirting, apply ground sheet, etc. Also (if you do this) air seal attic floor, install insulation in attic and add gable vents to reduce moisture/mildew.
