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 South 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 your South 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.

I'm considering converting my basement into an 800sqft(max allowed I believe per South Portland Code) in-law apartment. Thank you! Rhonda
Goudy St in South Portland
We have a finished basement that we have begun rehab on. The carpet has been ripped up and laminate flooring has been ordered. Upon doing this ourselves we discovered we may want a professional to look at a few things such as replacing our ceiling (possibly our siding), the stairway leading to the basement and a few other small details. Please contact me as soon as possible. We would like to discuss our options, timeline and pricing.
