Our Services
Four ways we prove the envelope works
Air, water, and roofing assemblies tested to published standards on commercial, multifamily, and high-performance residential projects.
Blower Door Testing
Whole-building and unit-level air leakage testing to confirm your assembly hits the target, and to show you exactly where it doesn't.
- Single and multi-fan RetroTec equipment
- Code compliance testing for 2024 IECC
- Multifamily compartmentalization testing
- Leak mapping with smoke and infrared
ASTM Water Testing
Standardized spray-rack and chamber testing on windows, doors, and wall assemblies to find water intrusion before drywall goes up.
- ASTM E1105 field water penetration testing
- ASTM E783 field air leakage on fenestration
- AAMA 501.2 nozzle testing on static joints
- Documented mock-up and in-place testing
Exterior Envelope Consulting
Drawing review, detailing, and on-site observation so the envelope is right the first time, not litigated three years later.
- Plan and submittal review before install
- WRB, flashing, and transition detailing
- Site observation and installer training
- Forensic investigation and repair scoping
Electronic Leak Detection
Non-destructive electronic leak detection locates breaches in TPO and waterproofing membranes without cutting the roof apart.
- Low-voltage and high-voltage ELD methods
- Pinpoint breach locations, marked on site
- New roof QA before warranty sign-off
- Plaza deck and below-grade waterproofing
Why teams call GHB
Independent, credentialed, and on site. Not subcontracted out.
We don't sell sealant, membrane, or repair labor. The only thing we're selling is an accurate answer about your building.
Third-party independence
No repair work, no product lines, no conflict of interest. Owners and lenders accept the results because we have nothing to sell on the back end.
Reports that hold up
Testing performed to the letter of ASTM, RESNET, and IECC protocol, documented with photos, instrument data, and clear pass/fail language.
Scheduled around your trades
We work the construction calendar, not ours. Testing windows are set so you aren't holding up drywall, siding, or a certificate of occupancy.
Problems caught early
Catching a failed transition detail at mock-up costs a fraction of finding it after occupancy. Most of our value shows up in the change orders you never write.

Documented findings with repair direction, plus verification testing once the corrections are in.
About Us
A Kansas firm built around one question: is it actually sealed?
Green Home & Building is an independent building envelope testing and consulting firm based in De Soto, Kansas. We were founded by two people who spent their careers on the construction side of the envelope, which is why our findings come with repair direction a superintendent can actually use, not just a number on a page.
We work for general contractors, developers, architects, roofing contractors, and building owners across the Kansas City metro and the surrounding region, on multifamily, hospitality, senior living, commercial, and high-performance residential projects.
