Ventilation duct cleaning for sites in South Merstham

What the work involves, part by part

Offices and retail

In offices and retail, we often work evenings, overnight or at weekends to keep the space open.

Grilles and diffusers

Dust marks around grilles can point to dirt further back in the system. We clean the grilles and look at what’s behind them.

Ventilation duct cleaning for kitchens and businesses in South Merstham

Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. If you’re dealing with odours carried round the building by the ducts and supply ducts with years of dust inside, we can put it right, from toilet extract systems, supply ductwork and offices and schools onwards.

In a place like South Merstham, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.

Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

In-house cleaning or a specialist?

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

When it’s something else

Ventilation duct cleaning can’t fix everything, and we’d rather say so up front. It won’t put right:

  • Ventilation that’s undersized for the building
  • Grease in kitchen extract systems, cleaned to TR19® Grease instead
  • Damp or mould problems coming from the building fabric

If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think.

Parts of the system we cover

  • Offices and schools
  • Toilet extract systems
  • Supply ductwork
  • General extract ductwork
  • Hospitals and care homes
  • Grilles and diffusers

How it works

A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and leave you the report. The visit itself takes a weekend for a modest system, with large buildings phased floor by floor. Visits to a place like South Merstham are planned ahead, so we arrive with what the survey says the job needs.

  1. We agree timings that suit the building, including evenings and weekends.
  2. Access panels are opened along each run.
  3. We photograph the ducts, then clean each section in turn.
  4. Grilles and diffusers are cleaned and refitted.
  5. We take after pictures and send the certificate and report.

Preparing for the visit

  • Make sure someone can let us in and lock up afterwards
  • Mention any locked doors, roof access or ceiling voids
  • Let us know when the site is closed or quiet

What affects the quote in South Merstham

Your quote is based on your site. We consider:

  • How easy every part is to reach
  • Working hours and out-of-hours timing
  • The size of the system
  • Any permits to work or inductions

A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

Helping us quote

You do not need the technical terms. Just send:

  • How we’d reach plant on a roof or in a plant room
  • Wide pictures of the system and the area around it
  • Any previous report or certificate
  • Where the site is and what kind of site it is

The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Questions from South Merstham

Can you come to South Merstham after we close?

Yes, nights and weekends are routine for us. Your customers, staff or residents in South Merstham needn’t be disturbed. Just call us on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.

Is South Merstham within the area you cover?

Yes. South Merstham is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What do you do to protect the area?

We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.

Can one contract cover all our sites?

Yes. You deal with one contact for every site in our area, with visits on a regular schedule.

Do we lose a day’s trading?

Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.

Are you fully insured?

Yes. Full insurance covers our work, and we’ve been trading since 2009.

What do you do with what you remove?

It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.

How often should ventilation ductwork be cleaned?

Under TR19® Air, the answer comes from inspecting the ducts. Heavily used buildings, or those with vulnerable occupants, may need attention more often.

What happens if it’s left?

After building work, cleaning the ventilation before people move back in makes sense. Otherwise construction dust left in the ducts is blown out once the system runs. You choose the date of a planned visit, and a breakdown never asks.

Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

Aftercare tips

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Keep grilles and diffusers dusted
  • Don’t block grilles with furniture or storage
  • Stick to the filter change schedule
  • Keep to the inspection interval in your report

What was cleaned is listed, along with any parts that weren’t accessible, backed up by before and after pictures. We’ll suggest where new access panels would help.

Protect the system during building work by switching it off or covering the grilles.
