Ventilation duct cleaning in Thornwood Common

Between visits

After the visit, a few habits help the work last:

  • Book the next inspection on the date the report recommends
  • Stick to the filter change schedule
  • Watch for water stains around grilles
  • Make sure nothing is stacked against extract grilles

A TR19® certificate and photo report follow every clean. Keep them in the maintenance log, with the date, location and technician recorded.

Deal with condensation and leaks near ducts promptly, as moisture makes dust stick.

About our ventilation duct cleaning in Thornwood Common

We get into the ducts through access panels along each run. Where there aren’t enough panels to reach every section, we note the uncleaned parts in the report, and new access panels can be installed for the next clean. Typical jobs include rooms that feel airless when the system runs and extract ducts clogged with lint and dust, on grilles and diffusers, supply ductwork and offices and schools.

Somewhere as small as Thornwood Common, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

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

What affects the quote in Thornwood Common

Before we fix a price, we need to know a few things. We check:

  • Access, including roofs, risers and ceiling voids
  • Site rules, permits and inductions
  • Parking and loading at the site
  • Working hours and out-of-hours timing

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

Helping us quote

We can often survey from photos. Try to include:

  • Your opening hours and when the area is out of use
  • Any symptoms, from odd noises to smells or leaks
  • Your last certificate, test record or report
  • Close-ups of filters, grilles, hatches or access panels

Need a price for ventilation duct cleaning? Please call us on 0345 646 2711 or email us with a few details about the site. We’ll talk you through the work and give you a fixed quote before you commit to anything.

Landlords, agents and facilities managers

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

What happens if it’s left?

In healthcare, care and education settings, ventilation cleaning is hard to put off. Clean ducts are part of providing good air for the people inside. Rural sites cannot always move to another kitchen or room when something fails.

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711 or send us an email for straight advice and a fixed quote.

What staff can safely do

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. That is our job.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

Thornwood Common: your questions answered

Do you work at weekends in Thornwood Common?

Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Thornwood Common needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.

Is Thornwood Common within the area you cover?

Yes. Thornwood Common is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.

How do you keep the site clean during the work?

We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.

How much time does a ventilation clean need?

It takes a shift or two for a small system, longer for a whole building. The size of the system and the access make the biggest difference.

Do you have a 24/7 line?

Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.

Are grilles and diffusers included?

Yes. Where they can be removed, they’re taken down, cleaned and refitted. The rest are cleaned where they are.

Will we have paperwork to show the system was cleaned?

Yes, both a certificate and a photo report. The report lists what was cleaned, anything not reached and the next inspection date.

Will you look at the ducts before quoting?

Yes, on every job. The survey shows the layout, the access and the condition before giving a fixed quote.

Common problems we fix in Thornwood Common

Moisture in ducts makes dust stick. Condensation and leaks turn loose dust into a stubborn layer, which is harder to shift later.

Keep an eye out for any of the following:

  • Toilet and washroom extracts full of fluff
  • Odours carried round the building by the ducts
  • Grilles and diffusers streaked with dirt
  • Ductwork with too few access panels to clean

For schools like St John's Church of England Voluntary Controlled School, the holidays are the usual time to inspect and clean ventilation.

Questions to ask before you book

  • Whether the whole system is included, or only the parts that are easy to reach
  • When they can work, and whether that’s outside your opening hours
  • Whether a survey comes first
  • If the quote is a fixed price or an estimate

How to choose an extract cleaning contractor

How the visit works

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a shift or two for a small system, longer for a whole building, and the area is cleaned down before we leave. If you can send photos, we can arrive in Thornwood Common knowing what to expect.

  1. We survey the system from drawings, pictures or a site visit.
  2. We inspect inside the ductwork at set points and photograph it.
  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. We issue a TR19® certificate and a photo report listing what was cleaned.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Make sure equipment near the work can be switched off and left to cool
  • Find the previous report, if there is one

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, the quote is fixed before any work is booked.
