Welcome to Yakima Building Science
Yakima Building Science delivers precise blower door tests and expert leakage evaluation, ensuring homes in Yakima, WA, meet strict energy codes and perform at peak efficiency. With five years of experience, we're proud to be a licensed, insured, and bonded company, offering reliable and affordable solutions that improve indoor comfort, reduce energy waste, and comply with the 2021 Washington State Energy Code. Blower door services are essential for identifying uncontrolled air infiltration caused by pressure differences between indoor and outdoor air or wind-driven forces. This testing allows us to evaluate how much air leaks into or out of a building and pinpoint problem areas. We perform testing according to RESNET/ICC 380, ASTM E779, and ASTM E1827 standards, providing every homeowner and builder with an official, timestamped report signed by a certified testing agency.
Certified technicians perform comprehensive air infiltration services and insulation inspections to ensure airtight construction and practical thermal barriers. Our inspections are backed by high-resolution thermal imaging, helping detect insulation gaps and hidden leaks that affect heating and cooling performance. Whether you're building a new or remodeling an existing home, our inspections ensure your project complies with R402.4.1.3 air change requirements, no more than 4.0 ACH for detached homes, and 0.25 CFM/sq ft for multifamily units. When it comes to ductwork, we help ensure your system meets R403.3.6 duct leakage thresholds, whether testing at rough-in, post-construction, or within conditioned space.
As certified professionals, we understand the importance of delivering accurate, code-compliant results every time. If you're a homeowner needing reliable home inspection support for energy efficiency and air leakage testing, we're ready to help.
