Common questions from Old Heathfield clients
Is Old Heathfield too far out for you?
Not at all. Old Heathfield is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Ghyll Road Industrial Estate, near Old Heathfield?
Yes. Estates, retail parks and business parks around Old Heathfield, Ghyll Road Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can you reseal penetrations after our M&E works?
Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals, and we reseal them to the specified detail.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Fire stopping for commercial buildings in Old Heathfield
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. Site teams most often ask us about seals disturbed by maintenance and left open and fire-rated sealant that has cracked or shrunk back, on pipe penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Old Heathfield, that means joint design, primers and backing rod as standard.
Smaller places such as Old Heathfield 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.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Put resealing into every M&E and fit-out package
- Have penetrations checked while they can still be seen
- Include service cupboards in routine inspections
- Keep product data and details in the fire safety file
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. For a building around Old Heathfield, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Flag any permit to work we’ll need
- Have the specification and drawings to hand
- Point out any areas we must not close
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Different surfaces, different methods
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.
Fire stopping around Old Heathfield: what changes locally
Old Heathfield is about 40 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Halls and meeting rooms at places like The Parish Church of All Saints sometimes gain new services, and any compartment wall crossed needs the specified seal. For a school such as Heathfield Community College, penetration sealing fits best at the end of the summer works.

Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Converted and older buildings near places like Old Heathfield tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

When to call us in Old Heathfield
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.
Clients normally get in touch after noticing one or more of the following:
- Openings left by services added after handover
- Unsealed joints where partitions meet the slab
- Hidden openings found during inspections
- Fire stopping installed outside its tested range
For a hospital such as Hellingly Hospital (5 miles south of Old Heathfield), penetration sealing is normally phased ward by ward, with infection-control rules agreed first.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- What site paperwork they can supply
- Whether old or failed sealant will be cut out, not overlaid
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Cost factors for service penetrations
What shapes the price:
- Working within restricted access windows
- Removal of failed or old sealant
- The product specified
- The total length or number of joints
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
