How we handle ventilation duct cleaning in Blackwater

Ventilation duct cleaning is something we carry out for buildings in Blackwater and right across Hampshire, in offices, schools, healthcare buildings and retail. Each building gets a survey first and a fixed quote. If you have dust marks around grilles and ceiling diffusers and construction dust left in ducts after a refit, we can put it right.

Smaller buildings around Blackwater often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.

A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part

Extract ductwork

General extract ductwork removes stale air from rooms, toilets and washrooms. They collect dust, lint and fibres and slowly narrow.

Schools and colleges

Holidays and weekends are the natural time to clean school ventilation, with nobody in the classrooms.

Looking after it afterwards

Think of this as the after-treatment advice, short and simple:

  • Report dust blowing from grilles right away
  • Make sure nothing is stacked against extract grilles
  • Store cleaning certificates where auditors can find them
  • Stick to the filter change schedule

We recommend when the system should next be inspected, based on what we found. Put it in the diary now so it does not slip.

Fit access panels where the ductwork can’t be reached. Hidden sections are the ones that get worst.

Why act early in Blackwater

Dust in ducts doesn’t go away on its own. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. You choose the date of a planned visit, and a breakdown never asks.

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

Blackwater: your questions answered

Do you work in villages like Blackwater?

Yes, we work in villages as well as towns, and Blackwater is covered. Let us know about access, parking and anything unusual about getting there when you book.

Can you clean school ventilation in Blackwater during the holidays?

Yes, holiday work suits schools best. Around Blackwater, the Food Standards Agency lists about 7 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.

What information do you need?

Some photos and a quick description of the system, with the address and opening hours. We will ask for anything else we need.

How does TR19 Air differ from TR19 Grease?

TR19® Air applies to the general ventilation in buildings like offices, schools and hospitals. Kitchen extract is covered separately, by TR19® Grease.

Do you have insurance?

Yes. Duct Doctor is fully insured, and the details are available on request.

Do you inspect before cleaning?

Yes, on every job. We check the layout, access and condition before giving a fixed quote.

What do you do with what you remove?

Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.

Do you look at the system first?

Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.

What we do, step by step

There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes from one overnight visit to a phased programme over several weeks. Visits to a place like Blackwater are planned ahead, so we arrive with what the survey says the job needs.

  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. Grilles and diffusers are cleaned and refitted.
  5. We take after photos and send the certificate and report.

Preparing for the visit

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Find the previous report, if there is one
  • Tell us about site rules, permits or sign-in

Staff cleaning versus specialist work

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
