Crawl Space Vent Covers in Maryland
After foundation vents are sealed from the inside as part of a crawl space encapsulation project, exterior vent covers maintain the appearance of the foundation while confirming the seal. OBW installs exterior crawl space vent covers as part of every vent sealing installation.

Why Vent Covers Matter After Sealing
When OBW seals foundation vents with insulated rigid foam plugs from inside the crawl space, the exterior vent opening still exists in the foundation wall. Without an exterior cover, that opening allows debris, insects, and rainwater to accumulate against the interior plug, eventually degrading the seal. Exterior vent covers close off the opening at the exterior face of the foundation, protecting the interior seal and completing the appearance of the foundation wall.
For Maryland homeowners in HOA communities or neighborhoods with active code enforcement, exterior vent covers also maintain a clean, finished appearance consistent with the neighborhood's standards.
Vent Cover Installation
OBW installs exterior vent covers in materials appropriate to your foundation type, typically painted metal or durable polymer, sized to fit standard foundation vent openings. Covers are fastened to the foundation wall with corrosion-resistant hardware and sealed at the perimeter to prevent moisture intrusion between the cover and the wall surface. Cover installation is performed as part of the vent sealing scope of work and is covered under OBW's workmanship guarantee.
Vent Covers Are Part of the Complete System
Vent covers in isolation, without interior sealing, provide minimal moisture protection. Air still circulates freely through covered vents that lack interior plugs. OBW's vent sealing work always addresses both the interior seal and the exterior cover as a coordinated system.
