Basement Remodeling in Sisters, OR

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 Sisters 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 Sisters, OR
New Homeowner Discovers Sagging Floor under Carpet - Sisters, OR

The Homeowners just purchased their home and wanted to redo some of the interior before moving in. The removed the old wood stove, and ripped up all the old carpeting, and that was when they discovered that the floor was sagging, especially in the spot where the old stove had been. The crawlspace never had additional support put in to be able to handle the weight. Over the years the moisture had seeped into the floorboards and the weight of the wood stove escalated the issue. With the carpet, this was difficult to see, but with the space bare, it was blatantly obvious. 

To protect this house we started by going in and removing all the old debris. Our experts then added in SmartJacks to the sagging floors so that the homeowners wouldn't have to worry about the homes floors giving out. We then added in a new 10 Mil Plastic Vapor Barrier that is tear resistant and sealed it along the interior of the crawlspace, securely wrapping it around each post so no water or moisture could creep into the woodwork. 

No More Water Intrusion for a Crawlspace in Sisters, Oregon

After receiving a call from a homeowner in Sisters, Oregon about a wet crawlspace, our crews went to help fix the problem. Our team removed debris from the crawlspace and then installed Terra Block underneath the CleanSpace encapsulation system to add extra insulation and padding. CleanSpace will not only keep out water vapors from entering the crawlspace but also help keep the heating costs down by keeping the floors warmer. A SaniDry dehumidifier was also put in the crawlspace to dry and filter the air, getting rid of damp or musty odors that may travel into the rest of the house. The customer and our team agreed that a SmartDrain plumbing leak system would be important to have in the crawlspace as well. Never again will the homeowner have to worry about plumbing leaks going unnoticed and possibly causing serious damage to their home. Th SmartDrain system not only alerts the homeowner of a leak but also drains away the water until the leak can be fixed. The customer can now rest easy about their dry crawlspace and overall health of their home.

We recently purchased a house and took up the carpet to find sagging floors especially in a corner where they had an 800 pound wood stove with no additional support.

We are purchasing this home. The inspector said the crawl space is dry and should just be checked periodically. I would like to know if a vapor barrier will keep out pests like rodents and snakes- purely for my own comfort and peace of mind.
