Fire stopping for businesses in Wye

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Why deal with it now?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings around smaller places like Wye, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Fire stopping in Wye

Facilities managers in Wye often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and cable penetrations, and the failures we are asked to look at most are builders’ foam or ordinary silicone in compartment walls and open linear gaps along the top of fire-resisting walls. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Wye is the same: the right product in a properly prepared joint.

Around smaller places like Wye, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email us and we’ll come back to it.

Your questions answered

How does the move away from BS 476 affect penetration seals in Wye?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is Wye too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

How many days will you need on site?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Commercial clients in Wye

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

When to call us in Wye

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.

Common reasons buildings call us in:

  • Damaged fire seals in risers and voids
  • Fire stopping installed outside its tested range
  • Snag lists that include open service penetrations
  • Unsealed openings around new pipes and cables

Hospital estates such as William Harvey Hospital, 3.1 miles south of Wye, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • What site paperwork they can supply
  • How the existing material will be dealt with
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Don’t let anyone top up a fire seal with the wrong product
  • Settle who seals which penetrations at the start of a project
  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs

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.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Service penetrations in Wye buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. At about 50 miles from central London, Wye is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

In a school such as Lady Joanna Thornhill Endowed Primary School, fire-rated sealant goes in around service penetrations where it is specified. In a building such as Church of Saint Gregory and Saint Martin, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Wye is about 4 miles north-east of Ashford, in Kent. Wye sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Wye is one of 931 places we cover in Kent for service penetrations. Sites around London have their own page, roughly 50 miles from Wye.

Business premises anywhere in TN25 are within our area for service penetrations. If your site is on High Street, Church Street and The Green or close by, we can quote for service penetrations. Just outside Wye, we also work in Kempe's Corner (1 mile west), Boughton Corner (1 mile north-west), Boughton Aluph (1 mile north-west), Brook (2 miles south-east) and Folly Town (2 miles south-east). Nearby towns on our patch include Ashford (4 miles south-west), Canterbury (9 miles north-east), Sittingbourne (14 miles north-west), Folkestone (12 miles south-east), Whitstable (12 miles north) and Faversham (9 miles north).

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Wye are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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 first.
  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

  • Arrange parking or a loading space
  • Tell us which areas need to stay in use
  • Tell staff and tenants when we’ll be in

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email the details over.

What the job involves on each surface

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables, so we check before sealing.
