How we handle fire stopping in Micklefield

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations, and the failures we are asked to look at most are open linear gaps along the top of fire-resisting walls and builders’ foam or ordinary silicone in compartment walls. For commercial sealant work in Micklefield, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places like Micklefield, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Micklefield

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

What tends to prompt an enquiry:

  • Expanding foam used as fire stopping
  • Seals disturbed by maintenance and left open
  • Head-of-wall gaps with no fire seal
  • Fire-rated sealant that has cracked or shrunk back

At a university such as Buckinghamshire New University, 1.6 miles west of Micklefield, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

How to choose a sealant contractor

FAQs: Micklefield

Can work at a site such as Buckinghamshire New University fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like Micklefield outside your area?

No. Places such as Micklefield are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What do BS EN 1366-3 and BS EN 13501-2 mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

From enquiry to 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, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If neighbouring businesses or buildings around Micklefield need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  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. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Why act early in Micklefield

An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. For buildings in places like Micklefield, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Take a look at what affects the cost or how we’re accredited.

Different surfaces, different methods

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables and we work within those limits.

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Where we work in Micklefield

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

Cost factors for service penetrations

A fixed quote reflects the actual work. It allows for:

  • The site’s rules and procedures
  • How much existing material needs removing
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Rough lengths or quantities, or drawings if you have them

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Penetration seals near Micklefield

In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. Micklefield is about 28 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

For a hotel such as Red Lion Hotel, 1.5 miles west of Micklefield, penetration seals are worth checking after any refit or services upgrade. Wherever services are added at a hospital such as Wycombe General Hospital (to the west of Micklefield) the compartment line has to be made good with the specified product.
