Trade Reality Notice Gary Pearce • 25+ Years on Tools

When Calculations Aren't Enough: Real-World Site Factors

While these calculators provide reliable trade estimates, physical site conditions often require hands-on adjustments: reflective white rendered walls causing IR glare, 2-foot Yorkshire gritstone attenuating radio frequencies, or high-level chimney stacks requiring non-drill lashing cradles.

• Fitted with CAI-benchmarked equipment and double-screened WF100 cable.

• All installations backed by Gary Pearce’s £10,000,000 Public Liability Insurance.
