Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief every trade that openings they make must be sealed
- Flag new cables with no seal around them
- Agree the fire-stopping specification before services go in
- Include service cupboards in routine inspections
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
How we handle fire stopping in Graveley
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you have open linear gaps along the top of fire-resisting walls and unsealed openings around new pipes and cables, we can help, on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Graveley it comes down to the same thing: the right product in a properly prepared joint.
Smaller places such as Graveley still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Questions about Graveley
Is a hospital such as Lister Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Graveley off your patch?
No. Places such as Graveley are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Is the BS 476 change in 2029 relevant to fire stopping?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, subject to transitional arrangements. In Scotland, the Technical Handbook sets its own guidance.
Why act early in Graveley
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. Older rural buildings around Graveley move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Pricing service penetrations depends on quantities, condition and access. Call for a quote.

Where services cross fire walls in Graveley
Graveley has a number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Colleges such as North Hertfordshire College, 1.1 miles to the south-west of Graveley, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a building around Graveley, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Let building users know which areas are affected
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand

Advice
When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Graveley can form part of a wider programme across Hertfordshire.

- Openings found when ceilings come down for a refit
- Service penetrations left open after M&E works
