Basement Remodeling in Amboy, WA

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly remodeled basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include:
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Amboy contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive basement that lasts a lifetime.

Job Stories From Amboy, WA
Old Home Gets Remodeled in Amboy, WA

This home was recently purchased and getting ready for a big upgrade. It had been sitting untouched for a while, and would need to be gutted and have a lot of work done. The homeowners started with waterproofing their crawlspace. Much of the home had old warped and torn up wooden floors that were going to be replaced, so the job would be installed with the flooring ripped up, and just the support beams present. 

Our installers began by cleaning out the crawlspace, a TripleSafe Sump pump was installed to keep the water out and away from the home, each post was then isolated with CleanSpace. We then installed our full crawlspace encapsulation package; starting with a dimpled drainage matt, then a TerraBlock crawlspace insulation, and all covered with our Cleanspace vapor barrier which is sealed against the walls and secured fully. The walls were covered in spray foam and a SaniDry Sedona dehumidifier was installed. With the crawlspace handled, the new homeowners could begin their next project on this old fixer upper. 

Torn and Chewed on Vapor Barrier - Amboy, WA

These homeowners never had a big issue with water in the crawlspace, but they did tend to have a vermin issue. They had a vapor barrier installed by another company, but after having it for a couple years they began to have odors drafting up from the crawlspace into their home. Upon further investigation, they saw that the barrier had been chewed on and torn in multiple spot, there was evidence of recent vermin activity and the homeowners needed a way to keep their home clean from the ground up.

Our installation crew came out and removed all of the old and damaged vapor barrier, we then put in our 20 Mil woven, tear-resistant CleanSpace barrier. This gets secured under each post and sealed up along the walls to create a full encapsulation that will keep the critters out and your air fresh and clean. 

Dry and Healthy Crawlspace in Amboy, Washington

After receiving a call from a homeowner with a wet crawl space, our crews went out to Amboy to fix the problem. They installed Terra Block on the floor of the crawl space to add extra insulation and padding. On top of the Terra Block and over the walls of the crawl space, our CleanSpace encapsulation system was installed. CleanSpace is a tough crawl space liner that keeps out water vapor and moisture. It also helps lower heating costs by keeping the floors warmer. Our team also used Spray Foam throughout the crawl space to fill every space and void and improve air sealing, saving the homeowner money on their energy costs. A SaniDry CX dehumidifier was also put in the crawl space to dry and filter out the air, preventing new mold growth or wood rot. A TripleSafe Sump pump was installed as well. The TripleSafe has three separate pumps, assuring protection from pump failure, too much water for one pump to handle and power failure with one of the three pumps being battery operated. It's the most reliable sump pump. Now the crawl space will be dry and healthy for years to come.
