How we handle fire stopping in Ashurst

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, and raise it with you if it falls outside. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and cable penetrations, and what we’re called in for most is head-of-wall gaps with no fire seal and old intumescent sealant that has split away. Whoever orders the work in Ashurst, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Ashurst, 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.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Ashurst

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. Halls, stores and units around places like Ashurst may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why us?

  • CHAS accredited
  • Public liability insurance in place
  • Work to your specification and the manufacturer’s guidance
  • 12-month guarantee on workmanship

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Leave fire sealant to cure fully before covering it
  • Include service cupboards in routine inspections
  • Report damaged or disturbed seals as soon as they’re spotted
  • Settle who seals which penetrations at the start of a project

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

Quoting for work in Ashurst

These are the things that shape the price:

  • How accessible the joints are
  • The size and state of each joint
  • Which sealant the job calls for
  • Travel to remote or island sites

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Where the site is, with the postcode

Ashurst: questions and answers

Will you take on work at estates like Speldhurst Business Park, close to Ashurst?

Yes. Our area takes in Ashurst and its surroundings, with estates and business parks such as Speldhurst Business Park included. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Can work at a site such as Canterbury Christ Church University - Salomons fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Will fire-rated sealant work on every penetration?

No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution, as set out by the designer.

Will you sign off the seals for us?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Penetration seals near Ashurst

Ashurst lies roughly 28 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. 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.

Halls and meeting rooms at places like Church of St Martin of Tours sometimes gain new services, and any compartment wall crossed needs the specified seal. Hospital estates such as Tunbridge Wells Homeopathic Hospital (to the east of Ashurst) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Residences at universities like Canterbury Christ Church University - Salomons (4 miles north-east of Ashurst) have compartment walls that must be resealed whenever services change.

Ashurst is about 5 miles west of Royal Tunbridge Wells, in Kent. Any commercial site in Ashurst is covered. Across Kent, 931 places are covered, Ashurst among them. There’s a separate page for Brighton, about 24 miles away.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Ashurst need work, visits can be combined. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned.
  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.

Getting the site ready
