Basement Finishing & Remodeling

So many contracting companies improperly finish basements because they use organic materials like wood and drywall. Basements are different than other areas of your home as it is the most likely area for water damage. These organic materials mold and rot quickly.

Our company is different because we only use our patented products which are completely inorganic & waterproof. If a pipe bursts, or a flood happens, or the basement leaks after rain your Portland basement will not ever be damaged. 

Our Finishing Products:

  • Waterproof, Washable, Insulated Walls
  • Mold-Resistant, No-Sag suspended Ceilings
  • Basement Dehumidifiers
  • Variable, Energy-efficient Basement Lighting
  • French, Bifold & six-paneled steel Doors
  • Basement Staircases
  • Energy-efficient, Double-paned Windows
  • Carpet, Tile & Faux Wood Flooring

Professional Mold Remediation

Our certified professionals will come to Portland and identify the areas of your home with mold and the type of mold. We then completely remove the mold as well as damaged materials from your home. 

Our Mold Services:

  • Energy-Efficient Dehumidification
  • Damaged Material Removal

Once the mold and damaged materials is completely removed, we rebuild the removed pieces of your home using mold-resistant materials. If needed we also install an energy-efficient dehumidifier to control the relative humidity to prevent future mold growth.

Looking to finish basement
Brentwood St in Portland
We are looking to refresh our unfinished basement. We don't want a full finish, but a sealed floor and walls -- basically a 'clean' look & feel so we can use the space for exercise and storage. If this is something you can tackle, I'd like to get a quote! Thanks!
Label Ave in Portland
We are interested in finishing our basement. It's pretty dry, but we get water in it maybe once a year during really big storms, so we'd need to talk about fixing that permanently too.
