Local points to consider
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
Working hours
Most Gravesend businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
