We lower the plumbing and make sure it works right. It’s the best stage to address all the issues in your communications or foundation structure.
We add a drainage system to protect the new underpinning basement structure from water and secure the area with a thick gravel layer.
We pour your new concrete floor, strengthen it, make sure it’s even, and smooth it out. In the end, it will look better than the old one.
Our team leaves no mess — we make sure the area is nice and clean before we leave you with your successfully finished underpinning basement.

WillFix Research – A Damp Basement Is a Health Hazard
Protecting your basement from moisture is crucial to avoid health issues. High humidity levels are perfect conditions for the development of many potentially dangerous organisms.

Insects
A variety of bugs can make your damp and dark basement their home, including:
- Centipedes (Chilopoda);
- Earwigs (Dermaptera);
- Millipedes (Diplopoda);
Some insects may spread diseases, and we doubt you’ll feel comfortable sharing a house with them.

Mould
Mould spreads rapidly, often appearing within 24-48 hours in wet basements:
- Dark-hued brown mould (Stachybotrys);
- Pale, dry mould (Aspergillus);
- Black mould (Stachybotrys);
The presence of mould in your home is concerning, because it causes different health issues.

Allergies
Basement-related allergies can range from being barely noticeable to profoundly distressing:
- Sneezing and/or coughing;
- Constant headaches;
- Anaphylaxis and difficulty breathing.
A damp basement might not only initiate allergic reactions in some but could also be the root cause of developing new allergies.
