Ductwork & Ventilation Installation

Galvanised ductwork runs installed through a plant room ceiling
Ductwork & ventilation

Ductwork and ventilation, fitted to the building

Measured on site, sealed as it goes in, balanced before handover

New duct runs, replacement work and ventilation systems for homes and small commercial premises — set out to the space they are going into.

Set out to the space

Runs are marked to the building in front of us, not scaled off a drawing.

Joint by joint

Joints, connections and hangers fixed and sealed as the run goes in.

Measured at the terminals

Airflow checked at each terminal and adjusted before we leave.

Components

The parts most jobs come down to

How each component is installed

Almost every ductwork job is built from the same short list of parts. Each one has to suit the route it is going into and the space it ends in.

How a job is priced

Priced from the survey, not from a list

We quote after seeing the space: the route it allows, the duct sizes it needs and the components that actually go in. Nothing is added without it being agreed with you first.

Component rates are published, so you can see how a figure is built up before anyone visits.

Where to start

Three ways most jobs begin

Most enquiries fall into one of these. If yours spans two of them, we will say so at survey and quote it as one job.

New installations

Complete ductwork and ventilation systems for fit-outs, extensions and new layouts, taken from first fix to a balanced system.

Replacement

Duct runs that have had their day removed and rebuilt to the same line, with the host unit checked once they are reconnected.

Ventilation systems

Supply and extract systems with their plant connections and air terminals, run up and set as a single system.

Before handover

Nothing is signed off until the airflow has been measured at every terminal and the dampers set to match.

If a route has to change once work has started, we agree the change with you before anything is cut.

Set out on site. Sealed as it goes in. Balanced before handover.

Rates shown are typical component ranges. The final figure follows the route, the duct sizes and the components a site actually needs — confirmed from a survey before any work starts.

Send us the space, we will quote the work

Drawings help but are not essential. Book a survey and the route gets set out on site, then the project is priced from what is actually needed.
