Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Signs you need fire stopping in Addlestone
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.
Site and facilities staff are often the first to spot these:
- Penetration schedules that need working through
- Unsealed openings around new pipes and cables
- Improvised or mixed-product fire seals
- Fire sealant pulled out of the opening
Tenant changes at parks like Bourne Business Park, 0.6 miles east of Addlestone, bring new data and services, and openings through fire-resisting walls need the specified seal.
What your quote should include
- Their public liability cover
- Is the sealant right for the movement and the substrate?
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
Fire stopping in Addlestone
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. If you are dealing with fire stopping installed outside its tested range and fire seals cut back for extra cables and never reinstated, we can put it right, on service gaps in risers, linear gaps at wall heads and pipe penetrations alike. For commercial sealant work in Addlestone, you deal with one contact from quote to sign-off, whether it’s one building or several.
Buildings in a smaller place such as Addlestone that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What sets the cost
To price the job, we consider:
- Whether the work must be split into stages
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Details that help us quote
To price the job accurately, we need to understand the site. Send us:
- The postcode of the building
- Whether an asbestos survey exists
- Clear photos of the problem areas
- How the joints are reached, and at what height
To get a fixed quote, give us a call on 01277 525 020 or email us, telling us the site location and the nature of the job. You can also send details through our quote form.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Where services cross fire walls in Addlestone
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. A 2-mile radius around Addlestone takes in plenty of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
On a hospital site such as St Peter's Hospital A&E, which lies west of Addlestone, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. In a retail centre such as Wey Retail Park (2.2 miles south of Addlestone), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
Addlestone is about 5 miles north-east of Woking, in Surrey. Anywhere in KT15, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Addlestone is one of 379 places we cover in Surrey. Sites around London have their own page, about 19 miles away.

Your questions answered
Is Addlestone off your patch?
No. Places such as Addlestone are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you plan work around the academic year at somewhere like Royal Holloway University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
What changes on 2 September 2029?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, subject to the Government’s transitional arrangements. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Will you write the fire-stopping specification?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.
Which standards are fire seals tested to?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2. The rating applies to the product as tested.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What the job involves on each surface
Plastic pipes
Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter, so we check before sealing.
From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. What matters most for a job in Addlestone is a clear list of what needs doing. A fixed quote follows.
- We start with your penetration schedule, drawings or specification.
- 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.
- Foam, ordinary sealant and debris come out 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.
Preparing the site
- Send any specification or drawings in advance
- Agree which areas must stay open
- Point out parking and an unloading spot

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Approving the work on behalf of building control
- Fire risk assessments, a job for a competent assessor
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.
