Ductwork cleaning in Hammer Bottom
Every duct has its own route. A few metres to an outside wall, or a riser up through the building to a roof fan. The survey traces the route and finds every access point before we quote. If you are dealing with sections of duct with no access panels and ductwork that has never been cleaned, we can help, from attenuators, vertical risers and access panels onwards.
Work in a small place like Hammer Bottom starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
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.

Ductwork cleaning in Hammer Bottom: the local picture
Food Standards Agency records include about 3 pubs, bars and clubs within roughly a mile and a half of the centre of Hammer Bottom. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Hammer Bottom is covered by Surrey Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Hammer Bottom, food businesses are inspected by environmental health officers from Waverley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
For schools such as Woolmer Hill School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Church and community hall kitchens, near The Parish Church of St Peter or anywhere around Hammer Bottom, are easy to forget, but their extracts collect grease like any other.

What ductwork cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A duct that’s too small or badly routed for the kitchen (a design issue)
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- A worn-out fan that needs replacing
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think before booking.
Where we work
- Multi-storey ducts
- Attenuators
- Bends and junctions
- Vertical risers
- Access panels
- Horizontal duct runs
How we price ductwork cleaning
A fixed price needs a few facts first. We check:
- Where the site is and how we reach it
- How easy every part is to reach
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before we start.
Helping us quote
To speed up the quote, please include:
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
To get a fixed quote, call 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
When to call us in Hammer Bottom
Grease filters that do not seal let fat straight through. The duct then takes grease that the filters should have stopped and it fills faster.
Any of these means the system needs a check-up:
- Stale grease odours from the duct
- Hardened, baked-on grease in long horizontal runs
- Ductwork that has never been cleaned
- A duct clean needed for an insurer
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Hammer Bottom is Haslemere and District Hospital, about 2.4 miles east.
What to look for in a quote
- If they look at the system before pricing
- Whether the quote shows VAT
- What records you’ll receive afterwards
- When they can work, and whether that is outside your opening hours
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Your questions about ductwork cleaning in Hammer Bottom
Is Hammer Bottom within the area you cover?
Yes, we work in villages as well as towns, and Hammer Bottom is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you work in Hammer Bottom outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Hammer Bottom can fit around your hours. Tell us your opening hours when you ask for a quote.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
How long does ductwork cleaning take?
Allow a few hours for a short run, longer for long runs and tall risers. We’ll confirm the time when we quote.
What happens if there are not enough access panels?
Without a way in, a section cannot be cleaned properly. We record those sections on the report and can fit access panels.
How much does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll usually reply within one working day.
What paperwork do you give after a duct clean?
A full system clean comes with a TR19 certificate and a photo report. It includes readings, photos and any unreachable sections.
How do you clean inside the ductwork?
We get into the duct through its access panels. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.

For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes from a few hours to more than one visit, depending on duct length and access. Photos of the system and how to reach it help us plan a visit to Hammer Bottom.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Between visits
After the visit, a few habits help the work last:
- Ask us about extra access panels where sections can’t be reached
- Keep access panels clear of stored items
- Flag drips from the duct straight away
- Keep the fan on while anything is cooking
After the clean, the same points are tested again, giving you before and after readings. Photos of each section go alongside them.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
