Tape Measure Slab Notes is a reference publication and does not operate a public contact desk.
Hiring Well
The usual checks are still the ones that matter. Verify licensing and insurance directly with the issuing body, get at least three written quotes, and ask each firm for recent local work you can look at.
Corrections
Where a guide is factually wrong, it gets corrected. A page nobody has revisited in three years is a liability, not an archive.
Not a Contractor
Nothing here is an offer of service. Anyone wanting the work carried out needs a contractor, which this site is not.
