Job Stories From Gresham, OR
Cleanspace Cleanup in Gresham Oregon

This crawlspace in Gresham was full of water and moisture and mold was beginning to form on the posts of the foundation Aurthur called our team to solve the problem. 

Vincent gave him a free inspection in which he included a dry out so that our crews could install the system, a perimeter drainage system, a sump pump, and then finishing the space with our anti-microbial, 20-millimeter thick CleanSpace Encapsulation material. 

The crawlspace was left clear, clean, and healthy for decades to come. 


CleanSpace, Sherwood, OR

Robert hadn't been in the crawl space of his house for years and had become concerned about the safety of the space. He saw an ad for John's Waterproofing in the Oregonian, a local newspaper here in Oregon and gave us a call. Our Senior Inspector, Jake went out to take a look and noticed the crawl space had a lot of debris in it and that the humidity levels were high. 

Within just a few days the crews were at Robert's house and cleaning out the debris and old equipment that was in the crawl space including the insulation. They installed a SaniDry XP Dehumidifier to stop the moisture and humidity,  a new TripleSafe sump pump. The entire crawl space was encapsulated and finished off with Spray Foam insulation. 

Robert is thrilled that he now has a healthy crawl space that functions the way it should and will for many many years.

Crawl Space, Gresham, OR

David and Jenny stopped by our booth at a Home and Garden Show with questions about the standing water they had in their crawl space. We gladly gave them an appointment with Design Specialist Vinny who went out to take a look and did find standing water and suggested a crawl encapsulation. Lupe and Fernando went out and after some plumbing repairs were able to install a SaniDry Sedona Dehumidifier to help keep the crawl space dry. Then an encapsulation with CleanSpace was done. Now David and Jenny have a clean dry basement with properly functioning equipment that will work for many years. 

High humidity leads to wood rot

This crawlspace in Gresham was full of water and had an exceptionally high relative humidity. Due to the nearly 80% relative humidity in the crawlspace, the insulation in the crawlspace was falling and molding. Many of the beams were beginning to show wood rot which if not cared for could threaten the structural integrity of the home. 

Our team removed the water in the crawlspace and installed a drainage system to ensure that they will not have water issues again moving forward. Our Triple Safe Sump Pump will ensure that water will no longer be an issue for the homeowner, and was required prior to the installation of the CleanSpace Encapsulation System. 

The system was completed with a dehumidifier installation to ensure that the humidity level in the crawlspace stays at a healthy range to provide quality air to homeowners above.

Self Installed Sump Pump to Water Guard; Gresham, OR

The customer us when his sump pump started to flood his basement due to sediment buildup. The discharge line they had installed, cracked leaving them with a bigger mess than they ever imagined. 

We came and dried out the basement. Taking out the old sump pump and discharge line. So that we could install our system without any hiccups. Francisco and his crew dug a trench line along the parameter of the basement for the WaterGuard

To replace the old sump pump they installed the SuperSump pump. With a 1 1/2 inch discharge line. Ensuring that when they laid the concrete down no water would intrude the space again. Or cause any more damage, leaving the customer overjoyed with knowing they have storage space once again.
