Fire stopping for commercial buildings in Grain
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. 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 unsealed openings around new pipes and cables and expanding foam used as fire stopping. One point of contact handles commercial sealant work in Grain from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like Grain, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Questions we are asked in Grain
What does the BS 476 change mean for fire-rated sealant in Grain?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you plan work around the academic year at somewhere like Sheppey College?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What will the job cost?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Which sealant the job calls for
- Joint width, depth and condition
- How accessible the joints are
- Induction, permit and paperwork requirements
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- The site address and postcode
- Access details, including height
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email drawings and photos.
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Issuing fire ratings or certificates for seals
- Writing the fire-stopping specification
- Large openings beyond what any sealant detail covers
If you are not sure, just ring 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
What we seal
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
- Linear gaps at wall heads
On site: what to expect
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 move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Grain are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Tell us which areas need to stay in use
- Make sure the joints can be reached
- Send your site hours and access windows

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Fire stopping in Grain: the local picture
Central London is about 35 miles from Grain. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. 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. Either way, we install the specified product to its tested detail.
Colleges such as Sheppey College (to the south-east of Grain) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Halls and meeting rooms at places like Church of St James sometimes gain new services, and any compartment wall crossed needs the specified seal. For a school such as St James Church of England Primary Academy, penetration sealing fits best at the end of the summer works.
Grain is about 5 miles north-west of Minster, in Medway. Commercial clients in Grain use us for work on service penetrations. Our Medway coverage takes in 54 places, from busy centres to rural villages. London is covered too, some 35 miles away.

What else we do in Grain
Leave it or put it right?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. Halls, stores and units around places like Grain may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.
