Basement Remodeling in North Bonneville, 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 North Bonneville 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 North Bonneville, WA
Broker Program - North Bonneville, WA

We often get calls from Brokers looking for a quote right away even though our System Designers are often booked weeks/months out. To ensure we can meet the quick turnaround for home sales, we have a dedicated realty design specialist.  This allows us to get approximate numbers to a broker in 1-2 days and, if they decide to move forward, then an inspection is done so give the broker a hard number to work with. This particular home had water intruding up to a few inches on top of the barrier.  A code no-no. This typically means that a PPP or Pipe/Pump/Plastic is in order so the home can pass inspection and the new owners are happy.


Our System installers were dispersed to do the work.  The old barrier, hanging insulation, and all other debris were removed from the crawlspace. A 3" perforated pipe drain system was installed around the perimeter and graded to the lowest point of the crawl where a SuperSump was installed to gather the water and discharge it out and away from the home. Then a new 6mil plastic barrier was installed on the floor of the crawlspace and attached to the foundation walls to ensure that any water seeping in via the footing or wall was captured and removed by the perf system. The new owners were happy and thrilled with the warranty!

Home for Sale, Check Under the House - North Bonneville, WA

If you are going to put a home on the market, it is best to do a thorough check of the home, and this includes checking the crawlspace or basement. To get this job to sell, the sellers needed to waterproof the crawlspace before closing. To get the job done right, John's Waterproofing was called in. 

Our crew began by doing a Dry out of the space and then clearing out debris from under the home. We then installed a SuperSump Plus which had three-inch perforated pipes bringing in the groundwater from the interior parameter of the crawlspace. All of the water was then pushed out and away from the home to a new LawnScape outlet. Some of the wooden posts were not on up to code footings, so we had to upgrade these footings to meet local codes. To finish we laid out a 6 mil vapor barrier. The home was then set for closing, and dry and healthy for the new homeowners. 

CleanSpace in North Bonneville, WA Crawlspace

This homeowner was concerned about the fact that his crawl space had water in it all winter. This can be problematic for the health of the home because moisture can cause mold, mildew, and odors that all get into the first floor of the house. Our inspector, Jacob, suggested installing our patented CleanSpace Encapsulation system, a SmartSump pump, and spray foam insulation.

Delfino and his team quickly set out to waterproof Tim's crawlspace and ensure the health of his home. The team installed our patented CleanSpace system which serves to encapsulate the crawl space, keeping out moisture, insects, and pests. Our CleanSpace system comes with a 25-year warranty and helps save money on energy costs. We also installed a SmartSump pump with an UltraSump back up battery to ensure that the sump pump will continue to pump water out of the crawl space even if the power goes out. The homeowner also had us install spray foam insulation which is a closed-cell foam that keeps out moisture and helps with energy costs by insulating the home's foundation.

Once our systems were in place, Tim no longer worries about water entering his crawlspace and can enjoy a cleaner, healthier, and more energy efficient home.
