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.

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.

Need an estimate for basement finishing.
Woodbury Street in Portland
Let me start by saying, we are not looking to finish our basement for another year or so, but my concern is that the foundation is cracked in multiple places and the walls are bowing. I know the whole basement foundation needs to be fixed and waterproofed, and I don't know if you offer that along with the basement finishing. If it's not something you offer, do you have suggestions of quality companies we could use to fix our foundation issues first? I will only ask/say this once, PLEASE do not call me, the number supplied is my cell phone number and because of my line of work I keep it on at all times. I work overnights at a local hospital and sleep during the day and would not appreciate being woken up to talk about my basement. My preferred method of contact is my email, which I have already supplied. You can feel free to email me anytime with any details of all the jobs that you do and offer or any suggestions of companies that could help us fix our foundation if it's not something we could do through you. otherwise, when I am ready, I will call you, should I wish to go forward with the process of having someone to the house for an estimate on fixing and finishing the basement. Thank you for your time, Ryan Pearson

Need to convert my basement into living space. My son and his girlfriend are expecting a baby at the end of the summer and I'll need a place that's quiet enough to sleep (I work two jobs). Nothing too fancy or elaborate. Don't have a huge budget.
