About our fire stopping in Ashtead

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. We work on service gaps in risers, cable penetrations and joints between fire-resisting walls and floors, and the failures we are asked to look at most are unsealed joints where partitions meet the slab and builders’ foam or ordinary silicone in compartment walls. Facilities teams, main contractors and managing agents in Ashtead tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a facilities manager in Ashtead, fire-rated sealing tends to follow other work: a new data cabinet, a heating upgrade, a kitchen refit. Checking after M&E works is good practice, and we will seal what’s found where fire-rated sealant is the specified product.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we are asked in Ashtead

What happens to BS 476 references for fire stopping in Ashtead?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Can you work at a site such as Regent Park Business Centre, by Ashtead?

Yes. We cover Ashtead and the area around it, including industrial estates, business parks and retail parks such as Regent Park Business Centre. A few photos and the unit address let us price the work.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you work in Ashtead?

Yes. Ashtead falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email the details over.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If you have more than one building in Ashtead, they can often be done on the same visit. Tell us when the building is open and we will plan to suit.

  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 first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Send your site hours and access windows
  • Point out parking and an unloading spot
  • Tell staff and tenants when we’ll be in

Advice

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Ashtead can form part of a wider programme.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Fire stopping around Ashtead: points for this area

At about 16 miles from central London, Ashtead is within reach of the capital. 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.

Offices at parks like Regent Park Business Centre (1.3 miles west of Ashtead) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. For an estates team at a campus like University for the Creative Arts, 2.2 miles to the north-east of Ashtead, summer M&E works are typically followed by a round of penetration sealing.

Ashtead is about 2 miles south-west of Epsom, in Surrey. Businesses, contractors and managing agents in Ashtead can call on us for service penetrations, as part of our coverage of Surrey. We work across 379 places in Surrey, from busy centres to rural villages. Sites around London have their own page, about 16 miles away.

If you need fire stopping in KT21 and KT22, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are The Street, Church Road and Greville Park Road, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Pachesham Park (2 miles north-west), Malden Rushett (2 miles north), Oxshott (3 miles north-west), Barwell (3 miles north) and Stoke D'Abernon (4 miles west) for service penetrations. Bigger towns within reach include Guildford (12 miles west), Woking (12 miles west), Horley (11 miles south-east), Redhill (8 miles south-east), Ewell (4 miles north-east) and Egham (13 miles north-west).

Why deal with it now?

The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. For businesses and landlords in Ashtead, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.

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

Do you need fire stopping in Ashtead?

Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.

Clients usually get in touch after noticing one or more of the following:

  • Fire sealant pulled out of the opening
  • Unsealed openings around new pipes and cables
  • Expanding foam used as fire stopping
  • Fire-stopping items raised at inspection or handover

Older community buildings such as St George's Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Questions to ask before you appoint anyone

What the job involves on each surface

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, along the full length of the run.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Fire doors, dampers or other fire safety equipment
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Plastic pipes whose detail calls for a collar or wrap

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly.
