Fire stopping in Chilham

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

Keeping the joints sound

For the best life from the joints:

  • File the specified details where the next contractor can find them
  • Don’t let anyone top up a fire seal with the wrong product
  • Agree the fire-stopping specification before services go in
  • Get seals inspected before ceilings and boxing close

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.

How we handle fire stopping in Chilham

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are service penetrations left open after M&E works and improvised or mixed-product fire seals. Facilities teams, main contractors and managing agents in Chilham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Chilham can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Compartments and services around Chilham

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. What we install is set by the specification, and it goes in to the tested detail. At about 49 miles from central London, Chilham is within reach of the capital. 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.

For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing. Hospital estates such as Kent and Canterbury Hospital, 5.3 miles east of Chilham, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Chilham is about 5 miles south-west of Canterbury, in Kent. Our applicators travel to Chilham for work on service penetrations. Across Kent, 931 places are covered, including Chilham. We also cover London, some 49 miles away.

We cover the CT4 postcode districts. Streets here include The Street, The Square and Bagham Road, and sites on any of them can send details for a fixed quote. Just outside Chilham, we also work in Mountain Street (1 mile south-west), Old Wives Lees (1 mile north), Godmersham (2 miles south), Shottenden (2 miles west) and Perrywood (2 miles north-west). Bigger towns within reach include Ashford (8 miles south-west), Canterbury (5 miles north-east), Sittingbourne (12 miles north-west), Folkestone (14 miles south-east), Whitstable (8 miles north) and Faversham (6 miles north-west).

Why act early in Chilham

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Halls, stores and units around places like Chilham may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Chilham can form part of a wider programme across Kent.

Chilham: questions and answers

Can you work on a hospital site such as Kent and Canterbury Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Chilham too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

What will the job cost?

Every job gets its own fixed quote. To get one, call 01277 525 020 or email a schedule or drawings.

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

No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.

How do I request a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Can you seal any opening with fire-rated sealant?

No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover.

Is BS 476 being phased out?

In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around Chilham, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Explain the parking and delivery arrangements
  • Share your working hours and any access restrictions
  • Move anything stored against the joints

Related advice

What we’re called out for in Chilham

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

Clients usually get in touch after noticing something like this:

  • Improvised or mixed-product fire seals
  • Expanding foam used as fire stopping
  • Damaged fire seals in risers and voids
  • Unsealed openings around new pipes and cables

On estates like CMA Industrial Park, 2.8 miles north-east of Chilham, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • What level of public liability insurance do they hold?
  • How they’ll work around occupants
  • Whether their applicators hold CSCS cards
