Fire stopping across Stoneleigh

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

Should maintenance staff do it?

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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

How we handle fire stopping in Stoneleigh

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and the failures we’re asked to look at most are improvised or mixed-product fire seals and builders’ foam or ordinary silicone in compartment walls. For commercial sealant work in Stoneleigh, you deal with one contact from quote to sign-off, whether it’s one building or several.

Converted and extended buildings around places like Stoneleigh can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. If neighbouring businesses or buildings around Stoneleigh need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  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
  • Flag any permit to work we’ll need
  • Arrange parking or a loading space

Quotes

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Service penetrations in Stoneleigh buildings

Stoneleigh has two care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Stoneleigh is about 11 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; the gaps need the specified seal.

Colleges such as North East Surrey College of Technology (1.5 miles south of Stoneleigh) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For a unit at a site such as Longmead Industrial Estate, 1.6 miles south-west of Stoneleigh, new power or data runs between office and warehouse can breach a compartment wall.

Stoneleigh is about 1 mile north-east of Ewell, in Surrey. Businesses, contractors and managing agents in Stoneleigh use us for work on service penetrations. We work across 379 places in Surrey, from busy centres to rural villages. Our London page has more on work in that area (11 miles or so).

Postcode districts covered here: KT17, KT19 and KT4 for service penetrations. We cover commercial and managed buildings on London Road, Station Approach and Stoneleigh Park Road and the roads nearby. We also cover Ewell (1 mile south-west), Worcester Park (1 mile north-west), Cuddington (1 mile south-east), Old Malden (1 mile north-west) and North Cheam (1 mile north-east). Nearby towns on our patch include Woking (14 miles west), Horley (13 miles south), Redhill (9 miles south), Egham (14 miles west), Reigate (9 miles south) and Walton-on-Thames (7 miles west).

Local landmarks in Stoneleigh

Locally, jobs take us to sites close to Hogsmill LNR, The Station pub and Ewell Castle School, among other places. Stoneleigh has its own railway station: Stoneleigh station. Nearby you’ll also find Cockney Museum (less than half a mile south-east) and Chessington Castle Hill (1.9 miles west). For a walk, there’s Kingston Hill Road area and The Lake.

Questions we are asked in Stoneleigh

Does your area include sites such as Longmead Industrial Estate, near Stoneleigh?

Yes. Estates, retail parks and business parks around Stoneleigh, Longmead Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Is a smaller place like Stoneleigh outside your area?

No. Places such as Stoneleigh are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, 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 seal openings left by new services?

Yes. Send the schedule or marked-up drawings and the specified product details. We can follow the services contractor floor by floor so areas aren’t left open.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Signs you need fire stopping in Stoneleigh

Head-of-wall joints and wall-to-wall junctions are frequent weak points. 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.

Clients normally get in touch after noticing something like this:

  • Fire-stopping items raised at inspection or handover
  • Seals disturbed by maintenance and left open
  • Old intumescent sealant that has split away
  • Openings found when ceilings come down for a refit

On a hospital site such as St. Ebba's Hospital (1.4 miles south-west of Stoneleigh), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

How the quote is worked out

We price every job individually. The main factors are:

  • Working within restricted access windows
  • Joint width, depth and condition
  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

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

  • Whether the building will be occupied during the work
  • Access details, including height
  • When you need the work done
  • The site address and postcode

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email drawings and photos.

Commercial clients in Stoneleigh

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Leave it or put it right?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. For buildings in places like Stoneleigh, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
