How we handle ventilation duct cleaning in Dartford

Supply ducts carry air into the rooms and extract ducts take it away. Dust and debris build up in both, and some of it is blown back into the building. We clean the ductwork, grilles and diffusers to TR19® Air. If you are dealing with extract ducts clogged with lint and dust and stuffy rooms and stale air, we can put it right, from offices and schools, supply ductwork and toilet extract systems onwards.

Around a town like Dartford, the buildings with ducted ventilation are typically offices, schools, surgeries and care homes. Their supply and extract ducts all gather dust over time, and TR19® Air sets out how to inspect and clean them.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What we do, step by step

A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the ventilation duct cleaning, tidy up and hand over the paperwork. The visit itself takes a weekend for a modest system, with large buildings phased floor by floor. Sites in a town like Dartford rarely need to lose trading hours, as the work fits around them.

  1. We look at the system and any earlier reports.
  2. We inspect the ducts at chosen points to see where cleaning is needed.
  3. We cover the area below and turn off the system.
  4. Ducts, grilles and diffusers are cleaned and the debris taken away.
  5. We report on the work, listing any inaccessible sections and the next inspection date.

Getting ready for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Mention any parking or loading restrictions
  • Arrange a key holder or contact on site

Ask for a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Aftercare tips

Aftercare is simple, and it makes the next visit easier:

  • Keep filters changed on time
  • Keep grilles and diffusers dusted
  • File each ventilation report with the building records
  • Make sure nothing is stacked against extract grilles

Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.

Don’t let construction dust into the ventilation by switching it off or covering the grilles.

For landlords and multi-site operators

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

Dartford questions

Do you work overnight in Dartford?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.

Do you offer ventilation duct cleaning in Dartford?

Yes, we work in Dartford and the places around it. To start, phone us on 0345 646 2711, or send details by email with a few photos of the system.

Do you have insurance?

Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.

What is TR19?

A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.

What happens to the waste?

It leaves the site with us when we go. During the work, it’s contained to keep the area clean.

What about areas you can’t get to?

They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.

Which kinds of sites do you work on?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

Do you offer maintenance contracts?

Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.

Honest limits

A few issues sit outside what this work can do:

  • Condensation caused by the building rather than the ducts
  • Problems with how the system is controlled
  • A system that isn’t designed to move enough air

Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly.

What affects the quote in Dartford

We don’t publish a price list, because sites vary so much. What we look at:

  • Parking and loading at the site
  • When the work can happen, such as evenings, overnight or weekends
  • What state the system is in
  • How big the system is

Kitchens, offices, schools and hospitals are all priced 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’ll explain each part.

What we need to know

Photos let us diagnose from a distance. Try to include:

  • The roof, plant room or outside wall the system runs to
  • Wide pictures of the system and the area around it
  • The postcode and the type of business
  • Any previous report or certificate

To get a fixed quote, give us a ring on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.

Different parts, different methods

Supply ductwork

Supply ducts carry air from the AHU into the rooms. Dust that slips past the filters builds up inside, and it’s cleaned out through access panels.

Hospitals and care homes

Hospitals and care homes are occupied day and night. We plan the order of work with the site team to keep disruption down.

What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
