Different surfaces, different methods
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
How we handle fire stopping in Upper Hartfield
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. If you’re dealing with old intumescent sealant that has split away and open linear gaps along the top of fire-resisting walls, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Upper Hartfield it comes down to the same thing: the right product in a properly prepared joint.
Smaller places such as Upper Hartfield 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.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Upper Hartfield: questions and answers
Does your area include sites such as Forest Row Business Park, near Upper Hartfield?
Yes. We cover Upper Hartfield and the area around it, including industrial estates, business parks and retail parks such as Forest Row Business Park. A few photos and the unit address let us price the work.
Can you work on a hospital site such as Crowborough War Memorial Hospital?
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.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Do you design or specify fire stopping?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it.
Do you approve fire stopping for building control?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
- Whether the work must be split into stages
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The product your specification calls for
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Arrange inspection before areas are covered up
- Don’t let anyone top up a fire seal with the wrong product
- Leave fire sealant to cure fully before covering it
- Make fire stopping part of every scope that crosses a fire-resisting wall
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Service penetrations in Upper Hartfield buildings
In England, Approved Document B covers fire stopping of 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. We install whatever has been specified, to the product’s tested detail. Upper Hartfield lies roughly 29 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
Large healthcare estates like Crowborough War Memorial Hospital (to the south-east of Upper Hartfield) change their services often, so penetration seals are worth checking after M&E work. Office fit-outs on sites such as Forest Row Business Park, 2.2 miles to the west of Upper Hartfield, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Signs you need fire stopping in Upper Hartfield
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
Things that normally lead to an enquiry:
- Seals that don’t match their tested detail
- Fire-stopping items raised at inspection or handover
- Service penetrations left open after M&E works
- Expanding foam used as fire stopping
In a building such as Holy Trinity Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Comparing quotes
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
- Their pre-qualification and accreditations
- Whether primer will be used where the manufacturer specifies it
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Upper Hartfield are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
Getting the site ready
- Confirm the product named in the specification
- Point out any areas we must not close
- Tell us your opening times and when work is allowed
