Need fire stopping in Myrke?

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

When something else is needed

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

  • Large openings beyond what any sealant detail covers
  • Signing off or certifying a building’s fire stopping
  • Construction that lacks the fire resistance the seal relies on

If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.

Where we work in Myrke

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

Fire stopping in Myrke, done properly

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal rather than guesswork. If you have fire-rated sealant that has cracked or shrunk back and fire seals cut back for extra cables and never reinstated, we can help, whatever the surface. Whoever orders the work in Myrke, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Myrke 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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building owners, agents and FMs in Myrke

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Service penetrations in Myrke buildings

At about 21 miles from central London, Myrke is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Myrke has three care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.

For a site team at a college like Windsor College (1.7 miles south-west of Myrke), fire-rated sealing is best scheduled after the summer works. On estates like Slough Interchange Industrial Estate, which lies north of Myrke, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Myrke is about 1 mile south-east of Slough, in Slough. Myrke sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Myrke is one of 11 places in Slough on our list for service penetrations. We also cover Reading, some 17 miles away.

We take on service penetrations across the SL3 postcode area, whatever the building. We also cover Ditton (1 mile south-east), Datchet (1 mile south-east), Sunnymeads (3 miles south-east), Brands Hill (3 miles south-east) and Old Windsor (3 miles south). Further afield, our area takes in Britwell (3 miles north-west), Huntercombe (3 miles north-west), Poyle (4 miles east) and Colnbrook (3 miles east).

When to call us in Myrke

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

What tends to prompt an enquiry:

  • Unsealed openings around new pipes and cables
  • Builders’ foam or ordinary silicone in compartment walls
  • Old intumescent sealant that has split away
  • Snag lists that include open service penetrations

Hospital estates such as Upton Hospital (0.5 miles north of Myrke) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • Can the work be phased to keep areas open?
  • How long is the guarantee, and what does it include?
  • Proof of insurance

How to choose a sealant contractor

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Myrke, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000

After the work

After handover, these steps help:

  • Agree the fire-stopping specification before services go in
  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs
  • Flag new cables with no seal around them

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.

Questions about Myrke

What happens to BS 476 references for fire stopping in Myrke?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Could you schedule work at a campus like Windsor College for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you cover Myrke?

Yes. Myrke is in our area. To discuss a job, speak to us on 01277 525 020 or send details through our quote form.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Can the building stay open while you work?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Surface by surface

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
