Attic & Crawl Space Ventilation
Static or passive ventilation plays a major role in the proper functioning of the building envelope.
Attic ventilation must be the proper net free sqft in ratio to the cubic sqft of the attic. The ratio of intake to exhaust must be correct, and only certain forms of intake can be used in conjunction with certain forms of exhaust.
The proper placement of the venting is crucial to avoid unintentional short-circuiting. Even the condition, screen size, and snow mesh have to be mathematically accounted for.
If your attic has signs of moisture, mold, discoloration, or overheating, we can provide testing to diagnose the root causes. During that process, attic ventilation is one of the spokes in the wheel that we can thoroughly test and correct.
Crawl space ventilation is almost always a static or passive net-free open vent with critter screens. Crawl space ventilation is designed to function as intake and exhaust, creating a cross-ventilation, allowing soil gases, moisture, allergens, and stale air to be exchanged with fresh, outside air. When relying on passive ventilation for a crawlspace, it is important to have the correct net free sqft in ratio to the cubic sqft of the crawlspace.
BPP can evaluate your crawl space, including the vents and screens, and provide recommendations.

“⭐⭐⭐⭐⭐
I am so grateful to these people for making our home livable again. They removed our old insulation along with the rats and all the mess they made. They were professional and got the jobs done on time. With a clean crawl space under the house, the leaks sealed, and rodent mitigation in place, it is like having a new home. Thank you!”
