This is a reading resource rather than a business, and it does not run a contact desk.
This Site Does Not Do the Work
The guides explain countertops work; they do not provide it. Anyone wanting the work carried out needs a contractor, which this site is not.
Corrections
Published guidance is reviewed and amended over time. Accuracy is the only thing a reference site has to offer, and a page out of date on a code requirement is worse than no page at all.
Hiring Well
Readers looking for someone to carry out the work are best served by the ordinary channels. Put the same written specification to every firm, so the prices that come back are actually comparable.
