About our fire stopping in Long Ditton
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you have open linear gaps along the top of fire-resisting walls and damaged fire seals in risers and voids, we can put it right, on cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads alike. Searching for sealant specialists in Long Ditton? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Buildings in a smaller place such as Long Ditton that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Fire stopping around Long Ditton: how the place shapes the job
In England, Approved Document B covers fire stopping of 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. A 2-mile radius around Long Ditton takes in a good number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
For a site team at a college like Hillcroft College, which lies north-east of Long Ditton, fire-rated sealing is best scheduled after the summer works. For a unit at a site such as Fairfield Trade Park, which lies north-east of Long Ditton, new power or data runs between office and warehouse can breach a compartment wall.

What else we do in Long Ditton
Why it’s worth doing now in Long Ditton
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. What matters most for a job in Long Ditton is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- 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.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
- Point out parking and an unloading spot

Advice
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Brief every trade that openings they make must be sealed
- Record which product was used where
- Agree the fire-stopping specification before services go in
- Ask which product is in place before decorating
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Long Ditton can sit alongside others in a wider programme across Surrey.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Your questions answered
Would you work within a site like Tolworth Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Will you work in a care home in Long Ditton without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Do you design or specify fire stopping?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.
How long does a typical visit take?
It depends on the scope, but the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we are not the right fit for that package.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Do you need fire stopping in Long Ditton?
Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Most enquiries start with one or more of the following:
- Fire sealant pulled out of the opening
- Penetration schedules that need working through
- Builders’ foam or ordinary silicone in compartment walls
- Service penetrations left open after M&E works
Large healthcare estates like Tolworth Hospital (1.3 miles east of Long Ditton) change their services often, so penetration seals are worth checking after M&E work.
Questions to ask before you book
- How they handle RAMS and site documents
- The terms of the workmanship guarantee
- How the existing material will be dealt with
- How they’ll work around occupants
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
