Ventilation duct cleaning near Denmead

Ventilation duct cleaning in Denmead, done properly

Ventilation duct cleaning is something we carry out for buildings in Denmead and right across Hampshire, from offices and schools to hospitals, care homes and shops. Each building gets a survey first and a fixed quote. We’re often asked to deal with musty smells from the ventilation and ductwork never cleaned since it was installed, across hospitals and care homes, toilet extract systems and offices and schools.

Visits to a place like Denmead are fitted around opening hours. The work is the same as in any town: inspect, clean, record.

Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Landlords, agents and facilities managers

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

Facilities teams in offices, schools and healthcare sites book us too across Hampshire. Larger estates can be phased building by building around the people who use them.

Between visits

Think of this as the after-treatment advice, in brief:

  • Stick to the filter change schedule
  • Keep grilles and diffusers dusted
  • Keep the TR19 certificate and photo report in the maintenance log
  • Keep vents and grilles clear of shelving and stock

Pass the paperwork to your facilities or maintenance team, so the history stays together. Over time, it shows how quickly the system gets dirty.

Fix leaks and damp near the ductwork quickly, as moisture makes dust stick.

Denmead: your questions answered

Will you come out to Denmead?

Yes. Villages and rural sites across the South East are part of our work, Denmead included. Photos of the system and directions to the site help us plan the visit.

Can ventilation in schools around Denmead be cleaned out of term?

Yes, and it’s the easiest time to do it. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Denmead. Just call us on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.

What accreditations do you have?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.

How do you deal with ducts you can’t get into?

The report shows exactly which parts weren’t reached. Access panels can be added where needed.

Are grilles and diffusers included?

Yes, together with the ductwork. They show up in the photo report before and after.

Where does the waste go?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.

What’s TR19?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Do we lose a day’s trading?

Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.

Fixed quotes for ventilation duct cleaning in Denmead

The price is fixed before any work begins. It takes into account:

  • Access, including roofs, risers and ceiling voids
  • Working hours and out-of-hours timing
  • The size of the system
  • The number of sites or systems

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

Helping us quote

Photos let us diagnose from a distance. Try to include:

  • Where the site is and what kind of site it is
  • Detail shots of panels, filters and grilles
  • The paperwork from the last visit, if you have it
  • Your opening hours and when the area is out of use

We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call us on 0345 646 2711 or email us.

What ventilation duct cleaning looks like in Denmead

Food Standards Agency data includes about 5 schools, colleges and universities and about 10 care, childcare and hospital premises in and around Denmead, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. Denmead is about 59 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. About 3.5 miles south of Denmead is Queen Alexandra Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

Healthcare ventilation, from large hospitals like Queen Alexandra Hospital (about 3.5 miles south) to small clinics, depends on clean filters, coils and ducts.

The process

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a weekend for a modest system, with large buildings phased floor by floor. Evenings, weekends or a closed day all work for a site in a place like Denmead.

  1. First we check the layout and any past paperwork.
  2. We inspect the ducts at chosen points to see where cleaning is needed.
  3. The work area is protected and the system switched off.
  4. Ducts, grilles and diffusers are cleaned and the debris taken away.
  5. We report on the work, listing any inaccessible sections and the next inspection date.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Make sure someone can let us in and lock up afterwards
  • Clear loose items from the work area

Getting a quote

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Advice

When it’s something else

To be straight with you, there are a few things this work will not fix:

  • Building management settings that run the plant
  • Kitchen extract ductwork, which needs a TR19® Grease clean
  • Design problems with the ductwork layout

If you are not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer before booking.

Where we work

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

Different parts, different methods

Schools and colleges

The work is fitted around term dates and events and agree access with the site team.

Grilles and diffusers

Where they come out, grilles are taken down and cleaned, then put back.

Signs you need ventilation duct cleaning in Denmead

Even good filters let some dust through, so fine dust settles in supply ductwork over the years. Extract ducts collect whatever the rooms give off: dust, fibres and lint.

What we’re most often called out for:

  • Duct runs that can’t be reached for cleaning
  • Blocked general extract ductwork
  • Ventilation full of debris from building work
  • Dirty diffusers dropping dust into rooms

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