Our operating approach
One connected approach.
Mr Hemp House® brings building, renovation, improvement coordination, materials, and professional delivery together around your project.
- 01
Understand
Gather information about the home and its concerns.
- 02
Prioritize
Identify appropriate next steps and where further evaluation is needed.
- 03
Improve or Build
Plan suitable work and material choices with the appropriate professionals.
- 04
Verify

- 05
Monitor
Track home information over time where supported.
This is our approach to a home over time. The scope of each phase is agreed for the project; not every phase is automated or available in every location.
Need a closer look?
A professional Healthy Home Assessment is one way to document concerns and develop a priority action plan. Review the scope, pricing, and availability before booking.

Understand the technology
Understand your home before you improve it.
HomeHealthScan™ helps organize information about your home. Home Health Score™ summarizes the available evidence to help identify priorities and track changes.
The score uses a defined methodology and depends on the information available. Questionnaire answers and AI inferences are not measurements. A score does not prove a home is safe, diagnose illness, or replace specialist evaluation.
