Need fire stopping in Buttsole?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Fire stopping in Buttsole

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you are dealing with improvised or mixed-product fire seals and expanding foam used as fire stopping, we can help, on joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations alike. One point of contact handles commercial sealant work in Buttsole from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places like Buttsole, 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Gaps in walls that were never built as compartment walls
  • Writing the fire-stopping specification
  • Openings that need collars, wraps, batts or boards rather than sealant

If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where we work in Buttsole

  • Cable penetrations
  • Small duct penetrations where the tested detail allows
  • Service gaps in risers
  • Joints between fire-resisting walls and floors
  • Linear gaps at wall heads
  • Pipe penetrations

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. If others near Buttsole need work, visits can be combined. You will have a fixed quote before work starts.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space

Advice

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. For buildings around smaller places like Buttsole, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Common questions from Buttsole clients

Do you cover business parks and estates near Buttsole, such as Birnham Farm Business Centre?

Yes. We cover Buttsole and the area around it, including industrial estates, business parks and retail parks such as Birnham Farm Business Centre. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.

Is a smaller place like Buttsole outside your area?

Not at all. Buttsole is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Do you hold third-party fire-stopping installer certification?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What do BS EN 1366-3 and BS EN 13501-2 mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. The rating applies to the product as tested.

What will the job cost?

We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

Service penetrations in Buttsole buildings

At about 63 miles from central London, Buttsole is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.

Older community buildings such as Church of St Mary the Virgin that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a school such as Eastry Church of England Primary School, penetration sealing fits best at the end of the summer works. Tenant changes at parks like Birnham Farm Business Centre, 1.5 miles to the north-west of Buttsole, bring new data and services, and openings through fire-resisting walls need the specified seal.

Buttsole is about 4 miles north-west of Deal, in Kent. We send applicators to Buttsole for service penetrations. We work across 931 places in Kent, from busy centres to rural villages. Sites around London have their own page, about 63 miles away.

Cost factors for service penetrations

A fixed quote reflects the actual work. It allows for:

  • The product specified
  • The total length or number of joints
  • Phasing around occupants
  • The site’s rules and procedures

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Access details, including height
  • The type of building and who uses it
  • When you need the work done
  • Any specification or named product

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

What the job involves on each surface

Metal pipes

Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.
