Grease, ductwork and the fire you do not see

TSPM FIELD NOTES
Above the ceiling

Most kitchen fires that spread beyond the kitchen spread through the duct. The canopy gets cleaned because you can see it. The run above it does not, because you cannot.

Access panels are the difference between a duct that can be cleaned and a duct that can only be replaced. They cost very little at installation and a great deal afterwards.

What we record

Every clean is photographed at the same points: canopy, filter bank, first bend, and each access panel along the run. The photographs are dated and kept, so the interval can be argued with evidence rather than opinion.

How a request works

Three steps, no call centre, and one email that decides everything.

1
You Send It
& A Person Reads It

Your request arrives at our office in Winterthur, where somebody actually reads it — not a queue, not an auto-responder rehearsing how much your enquiry matters to us. Tell us what has stopped working, where it is, and how badly you need it back. Photographs help far more than adjectives.

2
We Answer
& Usually Ask Something

You get one of two replies, quickly: a price with a time we can be there, or a question. The question is almost always about access, make or model — the unglamorous detail that decides whether our technician arrives with the right part or with an apology.

3
You Get The Email
& Only Then Is It Booked

Nothing is reserved until a written booking confirmation reaches you by email. Not when you send the form. Not when we reply. When that email lands. Until it does, the slot is genuinely still free — which is our polite way of saying somebody else can take it.
