Fire stopping in Mugswell

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

Questions we’re asked in Mugswell

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

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.

Will you plan work around the academic year at somewhere like University for the Creative Arts - Epsom?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you have public liability insurance?

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

Will you come and look before quoting?

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

How we handle fire stopping in Mugswell

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. The enquiries we see most involve improvised or mixed-product fire seals and fire-stopping items raised at inspection or handover, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Mugswell, preparation and product choice get the time they need.

A job near Mugswell is usually planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

How the job changes by surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

Commercial clients in Mugswell

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Quoting for work in Mugswell

These are the things that shape the price:

  • The site’s rules and procedures
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done
  • Any specification or named product
  • Whether an asbestos survey exists

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email us to discuss it first.

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Mugswell need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Have the specification and drawings to hand
  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings

Compartment walls and floors in Mugswell

Mugswell has a number of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. The 2 miles around Mugswell include two care or nursing homes. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

Campus buildings at universities such as University for the Creative Arts - Epsom, 4.6 miles to the north-west of Mugswell, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Colleges such as Reigate College, 2.7 miles to the south of Mugswell, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Mugswell is about 3 miles north of Reigate, in Surrey. Anywhere in CR5, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 379 places in Surrey, large and small. There’s a separate page for London, roughly 16 miles from Mugswell.

We cover the CR5 postcode districts for service penetrations. We also cover Gatton (1 mile south-east), Hooley (2 miles north-east), Merstham (2 miles east), South Merstham (2 miles south-east) and Netherne on-the-Hill (3 miles north-east) for service penetrations. Nearby towns on our patch include Epsom (5 miles north-west), Horley (7 miles south), Redhill (3 miles south-east), Ewell (6 miles north-west), Reigate (3 miles south) and Walton-on-Thames (12 miles north-west).

What we’re called out for in Mugswell

A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.

These are often picked up first by site or facilities staff:

  • Fire stopping installed outside its tested range
  • Openings left by services added after handover
  • Seals disturbed by maintenance and left open
  • Penetration schedules that need working through

Wherever services are added at a hospital such as Headley Court (to the west of Mugswell) the compartment line has to be made good with the specified product.
