Fire stopping for businesses in Kingston

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

When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Writing the fire-stopping specification
  • Gaps in walls that were never built as compartment walls
  • Issuing fire ratings or certificates for seals

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 before you book.

What we seal

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

How we handle fire stopping in Kingston

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you’re dealing with fire-rated sealant that has cracked or shrunk back and open linear gaps along the top of fire-resisting walls, we can help, on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kingston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Buildings in a smaller place such as Kingston that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

When to call us in Kingston

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.

Most enquiries start with one or more of the following:

  • Old intumescent sealant that has split away
  • Openings left by services added after handover
  • Seals disturbed by maintenance and left open
  • Head-of-wall gaps with no fire seal

On a site such as Wavendon Business Park, 0.9 miles south of Kingston, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Before you book anyone

  • Will CSCS-carded applicators be on site?
  • How joint depth will be controlled
  • What the guarantee covers, and for how long
  • Their pre-qualification and accreditations

Choosing a commercial sealant contractor

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. Work in places the size of Kingston is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Make sure the joints can be reached
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

Quotes

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or send photos by email.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • The total length or number of joints
  • Distance, for remote addresses
  • How much existing material needs removing
  • How accessible the joints are

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • The type of building and who uses it
  • Clear photos of the problem areas
  • Specification clauses that apply
  • Whether an asbestos survey exists

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or use the quote form to discuss it first.

Common questions from Kingston clients

Is Kingston too small for you to travel to?

Not at all. Kingston is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Does your area include sites such as Wavendon Business Park, near Kingston?

Yes, sites like Wavendon Business Park are within our area, along with the rest of Kingston. Send details of the unit and the work through our quote form for a quick quote.

Will you quote for a small job?

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

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Is fire stopping in Scotland covered by different guidance?

Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance.

Owners, agents and contractors

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Kingston. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Compartment walls and floors in Kingston

Kingston is about 45 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. A 2-mile radius around Kingston takes in several hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

At a university such as The Open University, 1.3 miles south-west of Kingston, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. At a college such as Milton Keynes College, which lies west of Kingston, checking penetration seals after summer M&E works is good practice.

Kingston is about 4 miles east of Milton Keynes, in Milton Keynes. Across the MK10 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Kingston is one of 62 places we cover in Milton Keynes for service penetrations. For work in that direction, see our Oxford page, about 31 miles away.

We take on service penetrations across the MK10, MK17 and MK7 postcode area. Streets here include Newport Road, Rothley Road and Wadhurst Lane, and sites on any of them can send details for a fixed quote. Main routes into Kingston include the A4146, which helps when planning parking and deliveries for the job. Nearby places we also cover include Glebe Farm (1 mile south-east), Broughton (1 mile north), Wavendon (1 mile south-east), Lower End (2 miles east) and Salford (2 miles east). Bigger towns within reach include Milton Keynes (4 miles west), Bletchley (4 miles south-west), Newport Pagnell (4 miles north-west), Bletchley and Fenny Stratford (4 miles south-west), Furzton (4 miles south-west) and Whitehouse (6 miles west).
