Access and parking
Town-centre jobs in Walthamstow 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.
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
