Before and After
  • Ugly basements keep people out
    Ugly basements keep people out

    This basement was slightly damp and looked similar to a newly liberated dungeon. Our homeowner wanted to transform the space and called us to help them get it ready. This changed the whole look of the basement. 

  • Finishing bathroom

    This family wouldn't even go down into this space, they had a whole downstairs that no one wanted to look at. Our team came in and installed silverglo insulation, a wall system and flooring. The family was so happy they finished the space and now they have a new bathroom they use daily!

    This space went from run down and unusable. After our crew was done the family had a functional area they could use for years to come!

  • Basement wall leaks

    This homeowner had a beautiful finished basement but this last year the wall was softening and has a strange dark area. When our team came out to inspect they discovered that this was due to a large concentration of wet soil behind the basement wall on the exterior. Over time water began to work its way through the concrete wall and now the family risked damage to the finished walls of their home. Our team came in and placed not only a drain system to collect this water but also installed our patented Bright Wall panels to ensure the walls of the basement remained strong for the life of the house.

    This basement started as removing water from the basement and the customer decided that he wanted a nice finished space and decided on Bright Wall finish panels to make the rest of it look finished and clean.

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
