Ventilation duct cleaning in Merrow

Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It’s risk-based and inspection-led, so every job starts with a look inside the ducts. If you have extract ducts clogged with lint and dust and duct runs that can’t be reached for cleaning, we can help.

For a building near Merrow, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.

Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How we price ventilation duct cleaning

The price is fixed before any work begins. It’s based on:

  • The scale of the work
  • How many systems or sites are involved
  • Access, including roofs, risers and ceiling voids
  • Working hours and out-of-hours timing

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

What we need to know

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • A few general shots of the system
  • Any previous report or certificate
  • Any symptoms, from odd noises to smells or leaks
  • Any access panels or hatches you can see

If you need ventilation duct cleaning in Merrow, phone us on 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. We usually send a fixed quote within one working day.

Merrow buildings and their air

The FSA’s food hygiene register lists about 12 schools, colleges and universities and about 12 care, childcare and hospital premises with registered kitchens or food service within about 1.5 miles of central Merrow. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Merrow is about 26 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. About 1.5 miles south-west of Merrow is St. Luke’s Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

Healthcare ventilation, from large hospitals like St. Luke’s Hospital (about 1.5 miles south-west) to small clinics, depends on clean filters, coils and ducts.

Merrow is about 2 miles east of Guildford, in Surrey. We carry out ventilation duct cleaning for commercial premises of every kind in Merrow and the rest of Surrey. Merrow is one of 395 towns, villages and districts in Surrey we cover for commercial clients.

We also cover Burpham (1 mile north-west), Abbotswood (1 mile west), West Clandon (2 miles north-east), Guildford (2 miles west) and Chilworth (2 miles south).

What the work involves, part by part

Offices and retail

In offices and retail, we often work evenings, overnight or at weekends so staff and customers are not disturbed.

Schools and colleges

We plan the work around the school calendar, with access agreed with the caretaker or site manager.

What happens on the day

We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a shift or two for a small system, longer for a whole building. Getting to the system matters more than parking in a place like Merrow, so let us know how to reach it.

  1. We start by looking at the layout of the ductwork and how it can be reached.
  2. Ducts are inspected at access points and the condition recorded.
  3. Floors and furniture are covered and the ventilation turned off.
  4. Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
  5. A certificate and before and after photos follow, with anything not reached recorded.

Before we arrive

  • Mention any parking or loading restrictions
  • Find the previous report, if there is one
  • Name a contact who can let us in at the agreed time

Getting a quote

There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, ring 0345 646 2711, or email photos.

For landlords and multi-site operators

Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

Facilities teams in offices, schools and healthcare sites book us too across Surrey. Work can be phased by floor, building or site around the people who use them.

Leave it or put it right?

After building work, cleaning the ventilation before people move back in makes sense. Otherwise the dust from the works comes out of the grilles once it’s switched back on. When a site near Merrow shuts unexpectedly, the people who rely on it notice at once.

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. Ask for a fixed quote and we’ll go through it with you.

What you get with us

  • One number for every site across the South East and London
  • BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
  • Survey first, then a fixed quote
  • Trading since 2009

When to call us in Merrow

Building work is one of the biggest sources of debris in ducts, particularly if it’s left running while work goes on. That dust can stay in the ducts long after the builders leave.

Any of these means the system needs a check-up:

  • Supply ducts with years of dust inside
  • Ventilation that needs a TR19® Air inspection
  • Blocked general extract ductwork
  • Dirty diffusers dropping dust into rooms

For schools like Bushy Hill Junior School, the holidays are the usual time to inspect and clean ventilation.

What to look for in a quote

  • Whether they’re fully insured
  • Whether the figure could change on the day
  • What happens if part of the system can’t be accessed
  • Whether the quote is based on a survey or photos

Choosing a duct cleaning contractor

When something else is needed

A few issues sit outside what this work can do:

  • Damaged ductwork beyond cleaning
  • Kitchen extract ductwork, which needs a TR19® Grease clean
  • Building management settings that run the plant

Not sure which it is? You can call us on 0345 646 2711 or send us an email and we will tell you honestly before booking.

What the work covers

  • Offices and schools
  • Supply ductwork
  • General extract ductwork
  • Toilet extract systems

Merrow: your questions answered

Do you work at weekends in Merrow?

Yes, we can come after you close and finish before you open. It means the site in Merrow keeps running as normal. Your opening times are the first thing we ask for.

Do you work in villages like Merrow?

Yes, we work in villages as well as towns, and Merrow is covered. A survey first, from pictures or a visit, means we arrive with the right kit.

Which sectors do you work in?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

Where does the waste go?

We take it away when we go. While we work, it’s kept contained to keep the area clean.

Is TR19 cleaning required by law?

No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.

Can you come out in an emergency?

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

Are you accredited?

Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

Can we book visits on a schedule?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
