Fire stopping for commercial buildings in West Dean
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal rather than guesswork. If you have openings left by services added after handover and penetration schedules that need working through, we can help, whatever the surface. Whoever orders the work in West Dean, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Smaller places such as West Dean still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

FAQs: West Dean
Can work at a site such as University of Chichester fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
What happens to BS 476 references for fire stopping in West Dean?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we will send them with the quote.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Do you cover West Dean?
Yes. Sites across West Dean are covered.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
When to call us in West Dean
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.
Site and facilities staff are often the first to spot these:
- Fire-rated sealant that has cracked or shrunk back
- Fire-stopping items raised at inspection or handover
- Builders’ foam or ordinary silicone in compartment walls
- Fire seals cut back for extra cables and never reinstated
Halls and meeting rooms at places like The Parish Church of St Andrew sometimes gain new services, and any compartment wall crossed needs the specified seal.
Before you book anyone
- The terms of the workmanship guarantee
- How the existing material will be dealt with
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Halls, stores and units around places like West Dean may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Fire stopping in West Dean: the local picture
At about 51 miles from central London, West Dean is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Schools such as West Dean CofE Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Residences at universities like University of Chichester (to the south of West Dean) have compartment walls that must be resealed whenever services change.

Cost factors for service penetrations
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- How much existing material needs removing
- The product specified
- Whether the work must be split into stages
- The site’s rules and procedures
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- Any dates the work must fit around
- Whether the building will be occupied during the work
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
How the job changes by surface
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any outside it are raised with you.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near West Dean need work, visits can be combined. A fixed quote is given before anything starts.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
