Access and parking
Town-centre jobs in Feltham often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Working hours
Most Feltham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
