Landlords, agents and facilities managers

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.

Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

How we handle ventilation duct cleaning in Harrow on the Hill

Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts carry anything the filters miss. We clean both, keeping the work tidy and the building protected. If you are dealing with poor airflow from the vents and ventilation that needs a TR19® Air inspection, we can put it right, from grilles and diffusers, supply ductwork and hospitals and care homes onwards.

In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Harrow on the Hill is usually planned out of hours. Loading and parking are planned with the building first.

The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Do you need ventilation duct cleaning in Harrow on the Hill?

Many systems run for long hours, day after day, and every hour of running brings more dust with it. Heavier use means faster build-up.

It’s time to book a visit if you see:

  • Systems missing access panels
  • Ventilation that needs a TR19® Air inspection
  • Ventilation full of debris from building work
  • Blocked general extract ductwork

Healthcare buildings such as Clementine Churchill Hospital, about less than half a mile south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Harrow on the Hill, yours matters too.

What your quote should include

  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • When they can work, and whether that’s outside your opening hours
  • How they set the interval to the next visit
  • Whether the whole system is included, or only the parts that are easy to reach

How to choose an extract cleaning contractor

How it works

Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes from one overnight visit to a phased programme over several weeks. A name and number for whoever controls access to the building in Harrow on the Hill saves time on the night.

  1. First we plan when the work can happen, often out of hours.
  2. We open the ductwork through its access panels.
  3. We photograph the ducts, then clean each section in turn.
  4. We clean the grilles and diffusers and put them back.
  5. After pictures are taken and the certificate and report issued.

Preparing for the visit

  • Plan for cooking equipment or plant to be off before we arrive
  • Make sure someone can let us in and lock up afterwards
  • Let us know when the site is closed or quiet

Getting a quote

Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or use the quote form.

Advice

Leave it or put it right?

A clean system moves air more easily, which puts less load on the fans. Leaving them means the plant works harder for the same result. It’s better booked as a planned job in Harrow on the Hill than handled as an emergency.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or email us and we will give you an honest view and a fixed quote.

Harrow on the Hill questions

Can parking be tricky for a job in Harrow on the Hill?

London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.

Do you work at weekends in Harrow on the Hill?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you call 0345 646 2711 or send us an email, mention when the site is quiet.

Who is responsible for fire safety on the premises?

It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.

How often should ventilation ductwork be cleaned?

It depends on the building, how the system is used and what inspection finds. Regular inspection tells you when it’s due.

Will we have to shut during the visit?

Not usually. The area we’re working in has to be out of use while we are there, so we book a time when it would be closed anyway.

Do you offer emergency callouts?

Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.

Do you work with multi-site operators?

Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.

What happens if you cannot reach some of it?

We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.

How the job changes from site to site

Supply ductwork

Supply ductwork delivers conditioned air to each room. Fine dust that gets past the filters settles along the runs, and we remove it through access panels.

Grilles and diffusers

Dust marks around grilles can point to dirt further back in the system. The grilles are cleaned and the ducts behind inspected.
