Fire stopping across Mogador

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

Different surfaces, different methods

Linear joints

Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in, with no gaps along the run.

Cables and cable bundles

New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.

Fire stopping in Mogador

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations, and the usual reasons a site gets in touch are fire sealant pulled out of the opening and openings found when ceilings come down for a refit. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Mogador is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural conversions around Mogador can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Where services cross fire walls in Mogador

Mogador has two care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified. Several hotels sit less than 2 miles from Mogador. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Theatres, wards and plant rooms at sites like Headley Court, 3.2 miles north-west of Mogador, all have compartment walls crossed by services. Office fit-outs on sites such as Chesterfield Business Park (1.3 miles south of Mogador) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Mogador is about 2 miles north-west of Reigate, in Surrey. We cover commercial sites throughout Mogador, whether it’s a single job or part of a planned programme. We work across 379 places in Surrey, from busy centres to rural villages. Sites around London have their own page, roughly 17 miles from Mogador.

Commercial sites across KT20 are covered for service penetrations. We cover commercial and managed buildings on Margery Grove and Mogador Road and the roads nearby. If your building is just outside Mogador, we cover Margery (1 mile east), Lower Kingswood (1 mile north-east), Walton on the Hill (2 miles north-west), Reigate (2 miles south-east) and Buckland (2 miles south-west). Bigger towns within reach include Guildford (15 miles west), Epsom (6 miles north), Horley (6 miles south), Redhill (3 miles south-east), Ewell (7 miles north) and Walton-on-Thames (12 miles north-west).

Common questions from Mogador clients

Is Mogador too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you work around term dates at a campus such as Reigate College?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you work in Scotland as well as England?

Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, using products tested for their end use.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Issuing fire ratings or certificates for seals
  • Walls or floors that aren’t fire-resisting to begin with

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Surfaces we seal

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

Why act early in Mogador

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. For buildings around smaller places like Mogador, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why appoint us

  • Health and safety: CHAS accredited
  • Fixed quotes based on photographs, drawings or a visit
  • One number for every site we cover
  • Work carried out by CSCS-carded applicators

Common problems we fix in Mogador

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Any of the following is a good reason to get the joints checked over:

  • Snag lists that include open service penetrations
  • Builders’ foam or ordinary silicone in compartment walls
  • Seals disturbed by maintenance and left open
  • Service penetrations left open after M&E works

Colleges such as Reigate College (1.7 miles south-east of Mogador) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

What to look for in a quote

  • Can the work be phased to keep areas open?
  • Whether old or failed sealant will be cut out, not overlaid
  • Their pre-qualification and accreditations
  • Their public liability cover

Our contractor checklist

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Mogador are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Brief every trade that openings they make must be sealed
  • Report damaged or disturbed seals as soon as they’re spotted
  • Arrange inspection before areas are covered up
  • Settle who seals which penetrations at the start of a project

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
