Fire stopping near Jordans

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire risk assessments, a job for a competent assessor
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think.

What we seal

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

Fire stopping in Jordans

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have penetration schedules that need working through and open linear gaps along the top of fire-resisting walls, we can put it right, on linear gaps at wall heads, cable penetrations and service gaps in risers alike. Facilities teams, main contractors and managing agents in Jordans tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Jordans is normally 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

When to call us in Jordans

Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

Things that typically lead to an enquiry:

  • Head-of-wall gaps with no fire seal
  • Old intumescent sealant that has split away
  • Openings left by services added after handover
  • Non-fire-rated filler around services

Older community buildings such as Church of Holy Trinity that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

What to look for in a quote

  • How the existing material will be dealt with
  • How joint depth will be controlled
  • Their pre-qualification and accreditations
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

FAQs: Jordans

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Jordans?

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.

Can you seal penetrations in a hotel in Jordans after a refit?

Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.

How many days will you need on site?

It depends on the scope, though a typical visit usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Do you offer coloured sealant?

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

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Compartments and services around Jordans

A number of hotels sit less than 2 miles from Jordans. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. 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 a school such as Jordans School, penetration sealing fits best at the end of the summer works. For a hospital such as Chalfonts and Gerrards Cross Hospital (1.5 miles east of Jordans), penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

Advice

Cost factors for service penetrations

Each job is priced on its own details. The things that drive the figure:

  • Distance, for remote addresses
  • How much existing material needs removing
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or use the quote form.

Building owners, agents and FMs in Jordans

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
