Fire stopping across Woolage Green

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Woolage Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

Fire stopping in Woolage Green, done properly

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. The enquiries we see most involve snag lists that include open service penetrations and open linear gaps along the top of fire-resisting walls, across pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads. A specialist sealant contractor works differently from a general builder: in Woolage Green, that means joint design, primers and backing rod as standard.

A job near Woolage Green is normally planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sets the cost

What shapes the price:

  • Access and working height
  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first

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.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Asbestos survey details if the building is older
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode
  • Photos of the joints, close up and from further back

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email us.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Brief every trade that openings they make must be sealed
  • Include service cupboards in routine inspections
  • Don’t let anyone top up a fire seal with the wrong product
  • Have penetrations checked while they can still be seen

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.

What the job involves on each surface

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.

Drylining partitions

Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness before sealing.

Why act early in Woolage Green

Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Around Woolage Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Common problems we fix in Woolage Green

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 and has to be removed.

Common reasons buildings call us in:

  • Fire seals cut back for extra cables and never reinstated
  • Head-of-wall gaps with no fire seal
  • Unsealed openings around new pipes and cables
  • Fire-rated sealant that has cracked or shrunk back

In a building such as Church of St Margaret, any service penetration through a fire-resisting wall should be sealed to the specified detail.

How to choose a sealant contractor

Woolage Green: questions and answers

Is Woolage Green too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Woolage Green?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Is your workmanship covered by a guarantee?

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

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Fire stopping around Woolage Green: how the place shapes the job

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. A 2-mile radius around Woolage Green takes in a number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

Hotels like Coach House Hotel (to the south-west of Woolage Green) are refurbished in phases, and each phase can open up compartment walls. For a unit at a site such as Aylesham Industrial Estate, which lies north of Woolage Green, new power or data runs between office and warehouse can breach a compartment wall.

Woolage Green is about 6 miles north-west of Dover, in Kent. Any commercial site in Woolage Green is covered, for single jobs and planned programmes alike. We work across 931 places in Kent, from busy centres to rural villages. Our London page has more on work in that area (60 miles or so).

If you need fire stopping in CT4, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Nearby places we also cover include Womenswold (1 mile north-west), Gravel Castle (2 miles west), Barham (2 miles west), Derringstone (2 miles west) and Aylesham (2 miles north). Nearby towns on our patch include Ashford (15 miles west), Canterbury (7 miles north-west), Margate (15 miles north-east), Dover (6 miles south-east), Folkestone (8 miles south) and Ramsgate (13 miles north-east).
