Why deal with it now?

An inspection-led approach avoids cleaning ducts that don’t need it. Skipping it leaves you guessing. Out of sight is the usual reason a rural system goes too long without attention.

Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

Why book with us

  • Trading since 2009
  • We are fully insured
  • One contact for all your sites in London and the South East
  • Survey first, then a fixed quote

Multi-site and managed buildings

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.

Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

Part by part

Offices and retail

Refits in commercial space often leave construction dust in the ducts. A clean before handover is a sensible step.

Extract ductwork

A dirty extract duct makes its fan work harder. Clearing the duct helps the fan do its job.

In-house cleaning or a specialist?

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Aftercare tips

How long the results last depends on use and care. Here’s what we suggest:

  • Tell your facilities team about dirty diffusers
  • Keep vents and grilles clear of shelving and stock
  • Store cleaning certificates where auditors can find them
  • Wipe grilles and diffusers during routine cleaning

Keep up with filter changes to protect the ducts. Overdue filters let dust straight back in.

Keep filters changed on time. Overdue or badly fitted filters let dust into the supply ducts.

How the visit works

Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from a single shift for a small office to a planned programme of nights for a large building. Rural roads and tight entrances are worth telling us about before a visit to Great Gaddesden.

  1. We survey the system from drawings, pictures or a site visit.
  2. Inspection comes next, with photos of the inside of the ducts.
  3. The area below is protected and the system switched off.
  4. Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
  5. You get a TR19® certificate and photo report, with any unreached sections noted.

How to prepare

  • Mention any parking or loading restrictions
  • Clear the space around the work
  • Agree a time when the area can be out of use

Ask for a quote

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

What we are called out for in Great Gaddesden

Moisture in ducts makes dust stick. Condensation and leaks turn loose dust into a stubborn layer, and it becomes harder to remove.

What we are most often called out for:

  • Stuffy rooms and stale air
  • Damp or stale smells from grilles
  • Ductwork with too few access panels to clean
  • Systems with no record of inspection or cleaning

If you manage a school such as Great Gaddesden Church of England Primary School, ventilation cleaning is best booked for the holidays.

Before booking anyone

  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether the quote is based on a survey or pictures
  • How VAT is shown on the quote
  • Whether a written report and photos are included

Our hiring checklist

Your questions about ventilation duct cleaning in Great Gaddesden

Can a school’s ventilation in Great Gaddesden be done out of term time?

Yes. The holidays are the usual time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Great Gaddesden. Send us your term dates when you give us a ring on 0345 646 2711 or email us, and we will fit the work in.

Is Great Gaddesden within the area you cover?

Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.

What do you need from me for a quote?

Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply ring 0345 646 2711 or drop us a line.

Is there a survey before the work?

Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

What happens to the waste?

We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.

How much notice do you need?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.

Are you insured?

Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

Who has the legal duty for fire safety?

The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you are not sure, check your lease and fire risk assessment.
