Basement Finishing & Remodeling in Seaside, 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 finished 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 Seaside 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 finished basement that lasts a lifetime.

Job Stories From Seaside, OR
Moisture in the Crawlspace in Seaside

Over time moisture had been getting into this customers crawlspace causing a huge issue. Mold had started to grow all over the crawlspace. Since up to 50% of the air you breathe comes from your crawlspace, he decided to give us a call for an inspection. 

Our inspector Vincent went out to check the crawlspace and come up with a plan to fix the problem. He recommended that we do a crawlspace encapsulation with our CleanSpace system. First, we would take care of all the mold with our Mold X2 cleaner that not only kills all the mold but removes the stains left behind.  We would install our TripleSafe sump pump that has three levels of pumps to ensure any water issues moving forward would be covered, and it also has a WaterWatch Alarm that will alert you if the water rises above the range to prevent damage. Paired with our SaniDry Sedona dehumidifier, and air filtration to keep the humidity down, mold and moisture cannot form. Encapsulated with our Cleanspace barrier and a new downspout for water to drain far away from the building water will never be an issue. 

Our customer was eager to have Delfino and his crew get started on his crawlspace. He now doesn't have to worry about water and moisture causing issues in his crawlspace and peace of mind knowing there is no more mold.

Water causes Mold in Seaside, OR Crawlspace

This homeowner was concerned about the amount of water entering into his crawlspace and the damage it was causing to his foundation. Being from the coastal area, water concerns are very common. After inspection, Jacob suggested installing our patented Cleanspace waterproofing system, a Smart Sump pump with an Ultra Sump back up battery system, and Mold X.

Cameron and his team quickly began to work towards waterproofing Paul's crawlspace. They installed out patented Cleanspace encapsulation system which serves to completely keep out all moisture and act as a barrier for insulation. This was installed with a Smart Sump pump with the backup battery Ultra Sump so that if power should go out, the sump pump will continue to work. We also used Mold-X which is a highly effective cleaner for the mold contaminated beams in the crawlspace.

Now that our waterproofing system is in place, Paul no longer has concerns over water entering his crawlspace and causing water damage and mold.

Hello. I am the owner of a manufactured home in a 55 + community in Seaside. I am seeking a qualified contractor to install a vapor barrier beneath my home. This is not a replacement, it seems that important piece of protection was never installed by any previous owner. open Mic level please let me know if this is something that your company does. If not, can you recommend someone other than a general contractor? I haven't gotten anywhere going that route. Thank you so much.

Water in crawlspace.
Vicinity of N. Holladay Dr. in Seaside
The crawl space under a portion of the house is not deep enough. This has created a welcoming environment for wood-boring beetles. I would like to have someone out to look at damage already caused by the beetles, as well as see the actions and costs involved in ensuring a sound crawlspace and foundation. Thank you
