About our fire stopping in Aston Abbotts

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, phone 01277 525 020 or email drawings and photos with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. We work on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and pipe penetrations, and the usual reasons a site gets in touch are damaged fire seals in risers and voids and fire stopping installed outside its tested range. For commercial sealant work in Aston Abbotts, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

A job near Aston Abbotts is usually planned around one visit, 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.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What we are called out for in Aston Abbotts

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.

If one of these sounds familiar, it’s time for a closer look:

  • Damaged fire seals in risers and voids
  • Expanding foam used as fire stopping
  • Openings found when ceilings come down for a refit
  • Fire sealant pulled out of the opening

Theatres, wards and plant rooms at sites like Tindal Centre, 3.7 miles to the south-west of Aston Abbotts, all have compartment walls crossed by services.

  • How they handle RAMS and site documents
  • Will CSCS-carded applicators be on site?
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Common questions from Aston Abbotts clients

What does the BS 476 change mean for fire-rated sealant in Aston Abbotts?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is Aston Abbotts too far out for you?

No. Places such as Aston Abbotts are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

After the work

Once the work is signed off, these steps help:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Ask the designer to confirm details early on refits
  • Record which product was used where
  • Don’t let anyone top up a fire seal with the wrong product

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Where services cross fire walls in Aston Abbotts

For England, the fire stopping of penetrations is dealt with in 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. We install whatever has been specified, to the product’s tested detail. Aston Abbotts is about 39 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Campus buildings at universities such as University Campus Aylesbury Vale, 4.4 miles to the south-west of Aston Abbotts, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. In a school such as Wingrave Church of England Combined School, fire-rated sealant goes in around service penetrations where it is specified.

What we can’t put right

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

  • Deciding what a wall or floor needs, which belongs to the designer
  • Plastic pipes whose detail calls for a collar or wrap
  • Reviewing a building’s overall fire safety

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

What we seal

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

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Aston Abbotts can be grouped with others nearby. You will have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  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.

Preparing the site

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

Should maintenance staff do it?

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Surface by surface

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.
