Ventilation duct cleaning for kitchens and businesses in Portsmouth
When the work is finished, you get a TR19® certificate and before and after pictures. The report lists what we cleaned, any sections not reached and a recommended next inspection, giving the ventilation a clean bill of health on paper. The work covers toilet extract systems, grilles and diffusers and general extract ductwork, and people most often call us about musty smells from the ventilation and toilet and washroom extracts full of fluff.
Offices, schools and hotels in Portsmouth stay in use while their ventilation is cleaned, so we work zone by zone, out of hours where needed.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Ventilation in Portsmouth buildings
There are about 48 schools, colleges and universities, about 49 caring premises (care homes, nurseries and hospitals) and about 16 hotels, B&Bs and guest houses on the FSA’s food hygiene register across Portsmouth and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. Royal Portsmouth Hospital is the nearest hospital, about 0.7 miles south-west of Portsmouth. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Hospitals such as Royal Portsmouth Hospital (about 0.7 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Portsmouth are no different. If you manage offices or shops near Fratton station, their ventilation can be inspected and cleaned out of hours.
Portsmouth is in England. Every kind of commercial site in Portsmouth, we can take on ventilation duct cleaning. Visits can be booked for evenings, overnight or weekends so trading is not interrupted. We cover 19 places across Portsmouth, large and small.
Work in PO6, PO4, PO1 and PO2 follows the same survey, fixed quote and written report as everywhere else we cover. If you need ventilation duct cleaning at premises on Church Road, April Square and Rudmore Square or a nearby road, we can help. Being close to the A3 and A27, Portsmouth is easy for our technicians to reach at any hour. If your site is just outside Portsmouth, we cover Rudmore (1 mile north-west), Landport (1 mile south-west), North End (1 mile north), Fratton (1 mile south-east) and Kingston (1 mile south-east). Further out, we also cover Wymering (3 miles north), Paulsgrove (3 miles north), Drayton (3 miles north-east) and Farlington (3 miles north-east).
Landmarks near Portsmouth
We work in commercial kitchens and buildings around The Portsmouth Academy, Alexandra Park and St Edmund's Catholic School and the streets around them. For rail, the closest station is Fratton station, roughly 0.9 miles south. Other landmarks nearby include Royal Portsmouth Hospital (0.7 miles south-west) and Charles Dickens Birthplace Museum (under half a mile west). For a walk, there’s Milton Locks and Portsdown Hill.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Protect the system from construction dust
- Get leaks near ductwork fixed quickly
- Keep vents and grilles clear of shelving and stock
- Store cleaning certificates where auditors can find them
Before any works, think about the ducts. Turn off the system or cover the openings during dusty jobs.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.
Part by part
Supply ductwork
Supply runs are inspected at set points first before deciding what to clean.
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.
Other services in Portsmouth
Managing agents and facilities teams in Portsmouth
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Portsmouth questions
Do you work at weekends in Portsmouth?
Yes, out-of-hours work is a big part of what we do. It means the site in Portsmouth keeps running as normal. Just call us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Can you do ventilation duct cleaning in Portsmouth?
Yes. Our area runs across London and the South East, Portsmouth included. A fixed quote normally follows within one working day of the survey details.
Is there a survey before the work?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
How often do ventilation ducts need cleaning?
It depends on the building, how the system is used and what inspection finds. Inspecting regularly shows when cleaning is needed.
What is TR19® Air?
It covers ventilation hygiene for supply and extract systems in offices, schools, hospitals and other buildings. Kitchen extract is covered separately, by TR19® Grease.
Is TR19 cleaning required by law?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
How the visit works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes from one overnight visit to a phased programme over several weeks. In the busier parts of Portsmouth, parking and roof access are the main things to plan.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- We clean the system and remove the debris from site.
- The report records what was cleaned, anything not reached and a next inspection date.
How to prepare
- Tell us where we can park and unload
- Find the previous report, if there is one
- Clear loose items from the work area
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Related advice
Do you need ventilation duct cleaning in Portsmouth?
Refits and building work send dust into ventilation systems, particularly if it’s left running while work goes on. That dust can stay in the ducts long after the builders leave.
Most sites get in touch when they notice one of these:
- Grilles and diffusers streaked with dirt
- Systems with no record of inspection or cleaning
- Duct runs that can’t be reached for cleaning
- Stuffy rooms and stale air
If you manage a school such as Manor Infant School, ventilation cleaning is best booked for the holidays.
Comparing quotes
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If they look at the system before pricing
- Whether the work can be done while the site is closed
- Proof of insurance
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
