Fire stopping in Westfield, done properly
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you’re dealing with unsealed openings around new pipes and cables and penetration schedules that need working through, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Westfield, preparation and product choice get the time they need.
Around smaller places like Westfield, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites around Westfield. One quote can cover more than one site, which keeps the paperwork simple.
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
What the job involves on each surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.
Compartment walls and floors in Westfield
A number of hotels sit less than 2 miles from Westfield. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
At a college such as Woking College, 0.7 miles north-east of Westfield, checking penetration seals after summer M&E works is good practice. Hotels such as DoubleTree by Hilton Hotel Woking, 1.5 miles north of Westfield, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. What matters most for a job in Westfield is a clear list of what needs doing. A fixed quote follows.
- 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.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Flag any permit to work we’ll need
- Let building users know which areas are affected
- Send your site hours and access windows

Advice
Westfield: questions and answers
Is Westfield too far out for you?
Not at all. Westfield is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you seal around new services in a hotel near Westfield?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
How do I request a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Common problems we fix in Westfield
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.
Most enquiries start with something like this:
- Fire sealant pulled out of the opening
- Unsealed penetrations discovered above suspended ceilings
- Seals disturbed by maintenance and left open
- Non-fire-rated filler around services
Where a unit on an estate such as Martlands Industrial Estate (1.6 miles south-west of Westfield), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
What to look for in a quote
- How they handle RAMS and site documents
- Do they follow the manufacturer’s priming guidance?
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
What affects the price in Westfield
To price the job, we consider:
- The total length or number of joints
- Site requirements such as inductions and permits
- Travel to remote or island sites
- Any access equipment needed
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Sending details for a quote
However big the job, the same details help:
- The postcode of the building
- Any specification or named product
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
Leave it or put it right?
An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. For buildings in places like Westfield, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
