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. For a job in Berry's Green, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we will need
- Have the specification and drawings to hand

Fire stopping in Berry's Green
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. The enquiries we see most involve head-of-wall gaps with no fire seal and service penetrations left open after M&E works, across service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows. For commercial sealant work in Berry's Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Berry's Green: questions and answers
What happens to BS 476 references for fire stopping in Berry's Green?
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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
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.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Looking after the joints
To get the most from the new sealant:
- Report damaged or disturbed seals as soon as they’re spotted
- Check risers and ceiling voids after each round of works
- Don’t let anyone top up a fire seal with the wrong product
- Agree the fire-stopping specification before services go in
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Signing off or certifying a building’s fire stopping
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer.

Fire-rated sealing for Berry's Green buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
Like every part of Greater London, Berry's Green is covered by the ULEZ, so vehicle access, loading and parking are planned before the first visit. On estates like Biggin Hill Airport Trading Estate, 1.4 miles west of Berry's Green, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. On a hospital site such as Princess Royal University Hospital, 3.6 miles to the north of Berry's Green, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Berry's Green is about 5 miles south of Orpington, in Greater London. We cover Berry's Green and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else.

Local landmarks in Berry's Green

The countryside around Berry's Green includes Betsom's Hill and Downe Bank.
Why act early in Berry's Green
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Getting scaffold, permits or access booked in Berry's Green takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
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 will put a fixed figure on it.
