Ductwork and ventilation work we carry out
Installed, replaced, modified and balanced — for homes and small commercial premises, whether the system is going in for the first time or being reworked.
Six kinds of work, start to finish
Most jobs on this list run into each other. If yours is a mix, we will say so at survey — scope is agreed before anything is cut.
02Ductwork replacement & modificationTired or damaged runs taken out and rebuilt, with the host unit re-checked.
03Ventilation systemsSupply and extract systems, plant connections and air terminals for the whole space.
04Vents, grilles & connectionsSupply and extract terminals set level, sealed and secured.
05System adjustments & checksAirflow measured at every terminal, dampers set until the system runs as designed.
06Components we name, fit and adjustDuct, grilles, dampers, plenums and extract fans — each has to suit the route.
Installation and replacement
New systems built to the route the space allows, and existing runs stripped out and rebuilt to the same line — with the host unit re-checked both times.
New ductwork installation
Complete ductwork and ventilation systems for fit-outs, extensions and new layouts.
- Runs set out to the drawings and to what the structure allows
- Duct and fittings installed, jointed and sealed
- Hangers, brackets and supports fixed back to the fabric
- Air-tightness checked before the system is handed over
Ductwork replacement & modification
Runs that have had their day taken out and rebuilt, with the host unit re-checked.
- Old ductwork removed and the route re-checked on site
- New sections made to size and installed to the same line
- Changes of direction, extensions and new branches added
- Host unit re-tested once the run is connected and sealed
Ventilation, terminals and components
Supply and extract systems, the terminals they finish at, and the components carrying the route between them. Each one is set to the space it is going into.
Ventilation systems
Supply and extract systems, plant connections and air terminals for the whole space.
- Supply and extract ductwork installed as one system
- Fresh air and extract pipework routed to each space
- Fan and plant connections made, sealed and supported
- System run up and balanced before handover
Vents, grilles & connections
Supply and extract terminals set level, sealed and secured.
- Grilles and diffusers set level and square to ceiling or wall
- Rigid and flexible connections made to the duct
- Sealing and insulation finished at every joint
- Noise and vibration checked at the terminal
Components we name, fit and adjust
Most jobs come down to the same components, and each one has to suit the route it is going into.
- Rectangular, spiral and flexible duct runs
- Grilles, diffusers and extract terminals
- Dampers, plenums and connections to plant
- Extract fans and the fixings that carry them
System adjustments & checks
Airflow is measured at every terminal, and dampers are set until the system runs as designed.
- Airflow set at the terminals, branch by branch
- Leakage points traced along the run and made good
- Balance and pressure confirmed with the plant running
- Re-checked before handover, with the changes agreed first
Set out on site. Sealed as it goes in. Balanced before handover.
Component rates
Every job is quoted from a survey, so the figure follows the route and the components a site actually needs. Typical component ranges:
Questions we are asked most
Three that come up on almost every survey. The rest are answered in full on the FAQ page.
- How is the price worked out, and what happens if it changes on site?
It is quoted from a survey against the route and the components. If a run has to change once we are on site, we confirm it with you before we cut. - How do we know the airflow is right when you finish?
Airflow is measured at every terminal and the dampers are set until the system runs as designed, before handover. - Do you work on homes as well as commercial premises?
Both — ductwork and ventilation for homes and small commercial premises, new work and existing systems alike.
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.
