What affects the price in Sheet Hill
Before we quote, we look at:
- Travel to remote or island sites
- How accessible the joints are
- Which sealant the job calls for
- The total length or number of joints
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- The postcode of the building
- What the building is and how it’s used
- Any specification or named product
- Approximate linear metres or a joint schedule
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
Fire stopping in Sheet Hill, done properly
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance. The enquiries we see most involve service penetrations left open after M&E works and damaged fire seals in risers and voids, on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations.

Barn and farm-building conversions near places like Sheet Hill often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Fire-rated sealing for Sheet Hill buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 23 miles from Sheet Hill. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
Holiday works at schools like Plaxtol Primary School often leave service openings to seal before pupils return. At a healthcare site like Cygnet Hospital Godden Green, 2.7 miles to the west of Sheet Hill, new services through compartment walls are a constant, and each needs the specified seal.

Signs you need fire stopping in Sheet Hill
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
Most enquiries start with one or more of the following:
- Open linear gaps along the top of fire-resisting walls
- Snag lists that include open service penetrations
- Fire sealant pulled out of the opening
- Non-fire-rated filler around services
For a building at a site such as Bourne Enterprise Centre, 1.8 miles to the north-east of Sheet Hill, a check of penetration seals after each fit-out is good practice.
What to look for in a quote
- How joint depth will be controlled
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
- Which product they’ll use, and why it suits the joint
How a job runs
Occupied buildings need a little choreography. 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. For work around Sheet Hill, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Point out parking and an unloading spot
- Confirm the product named in the specification
- Tell staff and tenants when we’ll be in

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Sheet Hill can sit alongside others in a wider programme across Kent.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
How the job changes by surface
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we’ll tell you what the detail says instead.
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Questions about Sheet Hill
Do you take on work at healthcare sites like Cygnet Hospital Godden Green?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens to BS 476 references for fire stopping in Sheet Hill?
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. Our part doesn’t change: the specified product, to its tested detail.
Do you cover Sheet Hill?
Yes. Sites across Sheet Hill are covered, and the same phone number covers every area.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
