Fire stopping for businesses in Aston Tirrold

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Aston Tirrold are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Flag any permit to work we will need
  • Send any specification or drawings in advance
  • Arrange parking or a loading space

Advice

Fire stopping for commercial buildings in Aston Tirrold

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors, and what we’re called in for most is damaged fire seals in risers and voids and unsealed penetrations discovered above suspended ceilings. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Aston Tirrold it comes down to the same thing: the right product in a properly prepared joint.

Smaller places such as Aston Tirrold still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email us and we’ll come back to it.

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Include service cupboards in routine inspections
  • Keep general-purpose fillers away from compartment walls
  • Keep product data and details in the fire safety file

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.

Fire stopping in Aston Tirrold: the local picture

Central London is about 48 miles from Aston Tirrold. Office refits around the commuter belt bring new cabling through fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

For buildings in and around Aston Tirrold, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail. Halls and meeting rooms at places like Church of St Michael sometimes gain new services, and any compartment wall crossed needs the specified seal.

Doing it in-house

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.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Cost factors for service penetrations

The price varies from site to site. Expect it to depend on:

  • Backing rod, priming and other preparation
  • The site’s rules and procedures
  • Distance, for remote addresses
  • Which sealant the job calls for

The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email a schedule or drawings with what you know.

Questions about Aston Tirrold

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

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 a smaller place like Aston Tirrold outside your area?

Not at all. Aston Tirrold is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Can the building stay open while you work?

In the majority of cases, yes. Phased work can be planned so areas stay in use.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Surface by surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Building owners, agents and FMs in Aston Tirrold

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
