Fire stopping in Middleton Stoney

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

Fire stopping for commercial buildings in Middleton Stoney

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Middleton Stoney and nearby. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers, and what we’re called in for most is old intumescent sealant that has split away and damaged fire seals in risers and voids. For commercial sealant work in Middleton Stoney, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Rural conversions around Middleton Stoney can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

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.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.

Leave it or put it right?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Converted and older buildings near places like Middleton Stoney tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

A quote for service penetrations depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

After the work

After handover, these steps help:

  • Get seals inspected before ceilings and boxing close
  • Record which product was used where
  • Include service cupboards in routine inspections
  • Brief every trade that openings they make must be sealed

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

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

How the quote is worked out

Before we quote, we look at:

  • Which sealant the job calls for
  • The size and state of each joint
  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

However big the job, the same details help:

  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email the details over.

Signs you need fire stopping in Middleton Stoney

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

Common reasons buildings call us in:

  • Non-fire-rated filler around services
  • Hidden openings found during inspections
  • Damaged fire seals in risers and voids
  • Open linear gaps along the top of fire-resisting walls

In a building such as Church of All Saints, any service penetration through a fire-resisting wall should be sealed to the specified detail.

  • What the guarantee covers, and for how long
  • How the existing material will be dealt with
  • Health and safety accreditation such as CHAS

How to choose a sealant contractor

Questions we are asked in Middleton Stoney

Is Middleton Stoney too far out for you?

Not at all. Middleton Stoney is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you seal around new services in a hotel near Middleton Stoney?

Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

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.

Service penetrations in Middleton Stoney buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Middleton Stoney has a number of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

For a unit at a site such as Bicester Shopping Park, 2.9 miles south-east of Middleton Stoney, any new service through a fire-resisting wall should be sealed to the tested detail. On a hospital site such as Bicester Community Hospital, 3 miles to the east of Middleton Stoney, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. If others near Middleton Stoney need work, visits can be combined. A fixed quote is given before anything starts.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work
