Case Studies
Study 1 :How We Install Our Spray Foam Insulation

| Before:A nasty, moldy crawl space | |

Note the bare dirt and gravel floor, the exposed beams, and cold concrete walls. Additionally, this crawl space has a serious moisture problem! More mold and rot would soon be on their way. (This crawl space is located in Nanoose Bay) |

First, we take care of the moisture problem with the CleanSpace crawl space vapor barrier system. By sealing off the crawl space vents and doors and covering the concrete and floor with a vapor barrier, we can be sure that moisture is kept back. Once this has been completed, we can begin to solve the cold problem by insulating the space. |

The walls and joists are covered with spray foam insulation. Spraying into the joist ends to stop air leakage is important for energy efficiency. The crawl space doors and vent covers also help to isolate the crawlspace from cold air outside. With the CleanSpace liner partially up the wall, the spray foam insulation creates a perfect seal. |
| After:An attractive, clean crawl space. | |

The entire crawl space is protected with a liner, with properly sealed floor, insulated walls, and insulated joist ends. Cold air is stopped from flowing upwards into the home. Utilities, heating ducts, and hot water pipes, are protected from crawl space air, and the entire home is more comfortable and energy efficient! |
Study 2: How to Transform a Crawl Space
with Insulation and Sealing
| Before: A dank, nasty crawl space | |
![]() |
The crawl space is filled with garbage, and damp insulation is dripping from the ceiling. Some of the floor is covered in a clear, 6 mil poly liner, but it's torn and not covering the entire floor. The concrete walls are cold and bare. |

Before we can get good work done on the crawl space, we must get rid of the mess. The thin, torn 6mil crawl space barrier is removed, as well as any debris on the crawl space floor. We also remove that old, dripping, wet insulation from the ceiling. |

Next, we smooth out the floor and install CleanSpace along the entire floor and along the walls. CleanSpace is a thick, durable 20-mil vapor barrier with a 25-year warranty for durability and resistance to tears and rips under normal use. The CleanSpace liner is laid out and sealed with a special waterproof tape. |

Next, spray foam insulation is applied to the concrete basement walls. This helps keep the space insulated from cold. Crawl spaces tend to hold utilities, hot water pipes, and heating ducts. When these things are protected from cold, they won't have to work as hard, saving you money. Additionally, cold will not seep up through the floor, which makes an uncomfortable home upstairs. |

If the crawl space had any issues with groundwater leakage, or you'd like to protect the space from potential plumbing leaks, we can install a crawl space sump pump in your home. This will effectively drain water out of the space. In the case of a plumbing leak, a special alarm can sound off to let you know of the problem right away. As you can see, the sump pump system is designed with a special lid that tucks neatly underneath the liner for a complete seal. The drain in the sump pump |
| After: An energy-efficient, moisture-protected crawl space! | |

With the sump pump system protecting the space, the liner and crawl space vent covers keeping away moisture, and the crawl space insulation keeping out the cold, you have a completely protected crawl space environment. The white liner and insulation makes for the best use of available lighting, while all joists and pipe penetrations are filled in with insulation. Your crawl space is drier, more attractive, and more useful than ever before! |
