Things to check in Chesham
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
Working hours
Most Chesham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
