Fire stopping for Broom Street sites

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

Quoting for work in Broom Street

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

  • Whether old sealant has to be cut out first
  • The size and state of each joint
  • The site’s rules and procedures
  • Access and working height

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

Sending details for a quote

We can often quote from photographs and a few details. Please tell us:

  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or use the quote form.

How we handle fire stopping in Broom Street

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Broom Street and nearby. Most enquiries involve expanding foam used as fire stopping and improvised or mixed-product fire seals, across service gaps in risers, linear gaps at wall heads and joints between fire-resisting walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Broom Street, preparation and product choice get the time they need.

Rural conversions around Broom Street can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Broom Street, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

What we need from you

  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use

Advice

Aftercare for building managers

After handover, these steps help:

  • Ask the designer to confirm details early on refits
  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep general-purpose fillers away from compartment walls
  • Look above ceilings when tiles are lifted for other jobs

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Your questions answered

Do you cover business parks and estates near Broom Street, such as Waterham Business Park?

Yes, sites like Waterham Business Park are within our area, along with the rest of Broom Street. Photos and a short description are enough for a first look.

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

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Can staff carry on working while you are here?

Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Is colour matching possible?

It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

What happens if it’s left?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. For buildings around smaller places like Broom Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Where services cross fire walls in Broom Street

For England, the fire stopping of penetrations is dealt with in 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. At about 46 miles from central London, Broom Street is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.

For a building such as Church of All Saints, new heating or data runs are the usual reason penetrations need sealing. Schools such as Graveney Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Wherever services are added at a hospital such as Whitstable and Tankerton Hospital, 5.6 miles north-east of Broom Street, the compartment line has to be made good with the specified product.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Writing the fire-stopping specification
  • Issuing fire ratings or certificates for seals
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

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