Fire stopping for Aston Rowant sites

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

Fire stopping for commercial buildings in Aston Rowant

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you are dealing with unsealed openings around new pipes and cables and fire stopping installed outside its tested range, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Aston Rowant is the same: the right product in a properly prepared joint.

For a smaller site near Aston Rowant, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

A 12-month guarantee applies to all our work in Oxfordshire. If an installation problem shows up, ring 01277 525 020 or send photos by email and we will arrange a return visit.

Building owners, agents and FMs in Aston Rowant

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

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.

What the job involves on each surface

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.

Aston Rowant: questions and answers

Is a smaller place like Aston Rowant outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Will you take on work at estates like Junction 5 Bates Industrial Estate, close to Aston Rowant?

Yes. Estates, retail parks and business parks around Aston Rowant, Junction 5 Bates Industrial Estate among them, are all within reach. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do you approve fire stopping for building control?

No. Approval sits with the designer, principal designer or building control. We’ll confirm the product and detail installed.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months.

What do you charge?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

Quoting for work in Aston Rowant

Your fixed quote is built from the real scope. It takes account of:

  • The product specified
  • Access and working height
  • Removal of failed or old sealant
  • Travel to remote or island sites

Pricing service penetrations depends on quantities, condition and access. Call for a quote.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • Whether an asbestos survey exists
  • Access details, including height
  • When you need the work done
  • A wide shot and a close-up of the area

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or send photos by email.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected 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. Smaller jobs around Aston Rowant can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  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. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Fire doors, dampers or other fire safety equipment
  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.

What we seal

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

General trades versus a specialist

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Penetration seals near Aston Rowant

For England, the fire stopping of penetrations is dealt with in 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. Either way, we install the specified product to its tested detail. Aston Rowant is about 39 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

Older community buildings such as Church of St Peter and St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a school such as Aston Rowant Church of England Primary School, penetration sealing fits best at the end of the summer works. Industrial units on estates such as Junction 5 Bates Industrial Estate, 2.8 miles south-east of Aston Rowant, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
