What affects the quote in Broad Colney
There’s no set price list, because sites vary so much. The quote depends on:
- Where the site is and how we reach it
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- Any permits to work or inductions
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Your last certificate, test record or report
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711, or email photos.
Ventilation duct cleaning in Broad Colney, done properly
Every ventilation system has ducts bringing air in and ducts taking it out. Over time, both collect dust and debris, some of which ends up back in the rooms. We clean the ductwork, grilles and diffusers to TR19® Air. The work covers grilles and diffusers, supply ductwork and offices and schools, and the jobs we see most are grilles and diffusers streaked with dirt and construction dust left in ducts after a refit.
Somewhere as small as Broad Colney, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Diary the next TR19® Air inspection
- Keep filters changed on time
- Keep the TR19 certificate and photo report in the maintenance log
- Wipe grilles and diffusers during routine cleaning
Share the report with whoever looks after the building’s maintenance, so the history stays together. Year on year, it shows how fast dust builds up.
Fit access panels where the ductwork cannot be reached. The worst build-up tends to be where no one can look.
Leave it or put it right?
Dust streaks around grilles and stale rooms suggest the ducts need looking at. Dealing with them now stops them getting worse. In a place like Broad Colney, ductwork and fans are easy to forget until something goes wrong.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Part by part
Supply ductwork
Supply ductwork delivers conditioned air to each room. Fine dust that gets past the filters settles along the runs, and we remove it through access panels.
Offices and retail
Offices and shops tend to need the work done outside opening hours to keep the space open.
What happens on the day
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes a weekend for a modest system, with large buildings phased floor by floor. Rural roads and tight entrances are worth telling us about before a visit to Broad Colney.
- We start by looking at the layout of the ductwork and how it can be reached.
- Ducts are inspected at access points and the condition recorded.
- Floors and furniture are covered and the ventilation turned off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Preparing for the visit
- Mention any parking or loading restrictions
- Clear the space around the work
- Let us know when the site is closed or quiet
Getting a quote
Getting a quote does not take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
