Aftercare for building managers
Regular inspection catches problems early. In particular:
- Agree the fire-stopping specification before services go in
- Put resealing into every M&E and fit-out package
- Look above ceilings when tiles are lifted for other jobs
- Have penetrations checked while they can still be seen
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Fire stopping in Sunningdale, done properly
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about snag lists that include open service penetrations and fire sealant pulled out of the opening, across service gaps in risers, cable penetrations and pipe penetrations. Whoever orders the work in Sunningdale, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Buildings in a smaller place such as Sunningdale 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.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Different surfaces, different methods
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Your questions answered
Can work at a site such as Imperial College Silwood Park Campus fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How does the move away from BS 476 affect penetration seals in Sunningdale?
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.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
What do you charge?
Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email a schedule or drawings.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Do you need fire stopping in Sunningdale?
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
Typical triggers for a call:
- Builders’ foam or ordinary silicone in compartment walls
- Penetration schedules that need working through
- Openings left by services added after handover
- Unsealed joints where partitions meet the slab
Hotels such as Royal Berkshire Hotel (0.5 miles north of Sunningdale) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For a job in Sunningdale, the main thing is a clear picture of the work. A fixed quote follows.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000

Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Issuing fire ratings or certificates for seals
- Deciding what a wall or floor needs, which belongs to the designer
- Construction that lacks the fire resistance the seal relies on
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Compartment walls and floors in Sunningdale
Sunningdale has two care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Tenant changes at parks like Ascot Business Park, 1.8 miles to the west of Sunningdale, bring new data and services, and openings through fire-resisting walls need the specified seal.
