Fire stopping across Walton

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping for commercial buildings in Walton

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal, not a rule of thumb. If you have openings found when ceilings come down for a refit and non-fire-rated filler around services, we can put it right, on cable penetrations, linear gaps at wall heads and pipe penetrations alike. Whoever orders the work in Walton, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

For a smaller site near Walton, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Every job we finish is backed by a 12-month workmanship guarantee, in Walton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Walton need work, visits can be combined. You will have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
  • Make sure the joints can be reached

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • The product specified
  • The total length or number of joints
  • Distance, for remote addresses
  • Phasing around occupants

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • The site address and postcode
  • Photos of the joints, close up and from further back

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call 01277 525 020 or send photos by email.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Fire doors, dampers or other fire safety equipment
  • Gaps in walls that were never built as compartment walls
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly.

Joints and surfaces we work on

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

What happens if it’s left?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Halls, stores and units around places like Walton may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

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 you will have a fixed figure to work with.

Walton: questions and answers

Will you work in a care home in Walton without moving residents out?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

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

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 colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

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, because fresh silicone will not bond with aged silicone.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

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.

Should maintenance staff do it?

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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Service penetrations in Walton buildings

Several hotels sit less than 2 miles from Walton. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Walton has five care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.

For a hospital such as Royal Buckinghamshire Hospital, 0.8 miles to the north-west of Walton, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. For a unit at a site such as Vale Retail Park, which lies north of Walton, any new service through a fire-resisting wall should be sealed to the tested detail. Shop fits in centres such as Friars Square (to the north-west of Walton) can bring new services through fire-resisting walls between units, which then need the specified seal.
