Fire stopping for Tunstall sites

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

When to call us in Tunstall

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.

Clients usually get in touch after noticing one or more of the following:

  • Non-fire-rated filler around services
  • Openings found when ceilings come down for a refit
  • Damaged fire seals in risers and voids
  • Fire-stopping items raised at inspection or handover

Campus buildings at universities such as Canterbury Christ Church University, 4.3 miles to the south-west of Tunstall, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

How to choose a sealant contractor

How we handle fire stopping in Tunstall

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance in Tunstall and nearby. If you are dealing with improvised or mixed-product fire seals and unsealed penetrations discovered above suspended ceilings, we can help, on pipe penetrations, cable penetrations and small duct penetrations where the tested detail allows alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Tunstall is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Tunstall, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, call the office on 01277 525 020 or use the quote form and we will arrange a return visit.

Fire stopping around Tunstall: what changes locally

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. The area within 2 miles of Tunstall holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

For a building at a site such as Kent Science Park, 0.8 miles to the south of Tunstall, a check of penetration seals after each fit-out is good practice. In a hotel such as The Bull Hotel, which lies north-east of Tunstall, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Tunstall is about 1 mile south-west of Sittingbourne, in Kent. Any commercial site in Tunstall is covered, for single jobs and planned programmes alike. Across Kent, 931 places are covered, including Tunstall. Our London page has more on work in that area (37 miles or so).

Commercial sites across ME9 are covered. Nearby places we also cover include Heart's Delight (1 mile north-west), Borden (1 mile north-west), Highsted (1 mile east), Rodmersham Green (1 mile east) and Sittingbourne (1 mile north-east) for service penetrations. Bigger towns within reach include Maidstone (9 miles south-west), Ashford (14 miles south-east), Whitstable (14 miles east), Faversham (7 miles east), Minster (7 miles north-east) and Kings Hill (14 miles west).

Tunstall: questions and answers

Can you seal penetrations in a hotel in Tunstall after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Would you work within a site like Sittingbourne Memorial Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

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: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Do you take on small jobs?

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

Quoting for work in Tunstall

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • How much there is to seal
  • Travel to remote or island sites
  • Which sealant the job calls for
  • How accessible the joints are

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • The product your specification calls for
  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • Your programme or deadline

For a fixed quote, give us a call on 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.

Work for main contractors and building owners

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Tunstall can be grouped with others nearby. You will have a fixed quote before work starts.

  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.

Getting the site ready

  • Share your working hours and any access restrictions
  • Flag any permit to work we will need
  • Make sure the joints can be reached

Request a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Related advice

After the work

For the best life from the joints:

  • Keep general-purpose fillers away from compartment walls
  • Arrange inspection before areas are covered up
  • Flag new cables with no seal around them
  • Agree the fire-stopping specification before services go in

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.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.

What the job involves on each surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer, and we’ll say if that applies.

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.
