Most Farnham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

A bypass avoids warming incoming air in summer.
Leased premises
If your Farnham premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
