About our fire stopping in Westhumble
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you have openings found when ceilings come down for a refit and damaged fire seals in risers and voids, we can put it right, on service gaps in risers, joints between fire-resisting walls and floors and pipe penetrations alike. Searching for sealant specialists in Westhumble? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Westhumble, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Fire doors, dampers or other fire safety equipment
- Approving the work on behalf of building control
- Large openings beyond what any sealant detail covers
If in doubt, phone 01277 525 020 or email the details over and we will say what we think before you book.
Surfaces we seal
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Westhumble can be grouped with others nearby. A fixed quote is given before anything starts.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Confirm the product named in the specification

How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- Travel to remote or island sites
- Joint width, depth and condition
- Whether the work must be split into stages
- Access and working height
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Sending details for a quote
We can often quote from photographs and a few details. Please tell us:
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- How the joints are reached, and at what height
- Your programme or deadline
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or use the quote form with what you know.
Questions about Westhumble
Is Westhumble off your patch?
No. Places such as Westhumble are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work at a site such as Glebelands Centre Business Park, by Westhumble?
Yes. Estates, retail parks and business parks around Westhumble, Glebelands Centre Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is your workmanship covered by a guarantee?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.
What changes on 2 September 2029?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Do you work in Scotland as well as England?
Our area runs from Greater London and the South East to every part of Scotland. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, using products tested for their end use.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Do you need fire stopping in Westhumble?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position and has to be removed.
It’s worth sending us details if you spot any of the following:
- Penetration schedules that need working through
- Openings left by services added after handover
- Fire stopping installed outside its tested range
- Unsealed penetrations discovered above suspended ceilings
In a building such as Church of St Michael, any service penetration through a fire-resisting wall should be sealed to the specified detail.
