Why deal with it now?
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small. For buildings around smaller places like Maresfield, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

How we handle fire stopping in Maresfield
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in. We work on cable penetrations, pipe penetrations and joints between fire-resisting walls and floors, and the failures we are asked to look at most are seals that don’t match their tested detail and hidden openings found during inspections. Facilities teams, main contractors and managing agents in Maresfield tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller places such as Maresfield still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our workmanship is guaranteed for 12 months, in Maresfield as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Questions we’re asked in Maresfield
Is hospital work, at somewhere like Uckfield Community Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What does the BS 476 change mean for fire-rated sealant in Maresfield?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months on every job.
Fire-rated sealing for Maresfield buildings
At about 36 miles from central London, Maresfield is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in 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. What we install is set by the specification, and it goes in to the tested detail.
For a school such as Bonners CofE School, penetration sealing fits best at the end of the summer works. On a site such as Ashdown Business Park, less than half a mile south-west of Maresfield, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What we are called out for in Maresfield
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.
What tends to prompt an enquiry:
- Fire-rated sealant that has cracked or shrunk back
- Non-fire-rated filler around services
- Seals that don’t match their tested detail
- Seals disturbed by maintenance and left open
Hospital estates such as Uckfield Community Hospital, 2.3 miles to the south-east of Maresfield, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
- Is the sealant right for the movement and the substrate?
- What site paperwork they can supply
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Maresfield can be grouped with others nearby. You will have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
