Five Minute Method is a reference publication and does not operate a public contact desk.
Finding a Contractor
The usual checks are still the ones that matter. Put the same written specification to every firm, so the prices that come back are actually comparable.
Accuracy Over Time
Published guidance is reviewed and amended over time. Standards change, materials are discontinued, and prices move, and a guide that has not kept up is actively misleading rather than merely stale.
Not a Contractor
Nothing here is an offer of service. No booking can be taken here, no price quoted, and no individual firm recommended.
