Fire stopping across Broadfield

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

What affects the price in Broadfield

The price varies from site to site. It mainly depends on:

  • Location, for remote and island sites
  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • How much there is to seal

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

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Drawings or a marked-up plan, if available
  • The type of building and who uses it
  • A wide shot and a close-up of the area
  • Any dates the work must fit around

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, phone 01277 525 020 or email us.

Fire stopping for commercial buildings in Broadfield

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. We work on small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors, and the failures we are asked to look at most are improvised or mixed-product fire seals and hidden openings found during inspections. Searching for sealant specialists in Broadfield? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Around smaller places like Broadfield, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

The 12-month guarantee is for workmanship rather than 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.

For managing agents and facilities managers

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.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Different surfaces, different methods

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, with no gaps along the run.

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 first.

Questions about Broadfield

Is hospital work, at somewhere like Crawley Hospital, something you do?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you work on fire-rated sealing in hotels in Broadfield?

Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

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.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.

What do you charge?

There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

Where services cross fire walls in Broadfield

In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Broadfield is about 28 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

In a retail centre such as County Mall, 1.5 miles north-east of Broadfield, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. On a hospital site such as Crawley Hospital, 1.5 miles north of Broadfield, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Broadfield is about 1 mile south-west of Crawley, in West Sussex. Anywhere in RH11, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our West Sussex coverage takes in 373 places, large and small. There’s a separate page for Brighton, roughly 18 miles from Broadfield.

Anyone looking for fire stopping in RH11 and RH10 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your site is on Terry Road, Hobbs Road and Clark Road or close by, send details and we’ll quote for service penetrations. Just outside Broadfield, we also work in Kilnwood Vale (2 miles west), Colgate (2 miles south-west), Faygate (2 miles west), Handcross (3 miles south) and Plummers Plain (4 miles south). Nearby towns on our patch include Horsham (5 miles west), Haywards Heath (8 miles south-east), Burgess Hill (10 miles south), East Grinstead (9 miles east), Billingshurst (12 miles south-west) and Roffey (4 miles west).

What’s near Broadfield

We work on buildings around Cottesmore School, Target Hill Park and The New Moon pub and the streets around them. Broadfield’s nearest station is Crawley station, about 1.4 miles north-east of the centre. A little further out are Crawley Hospital (1.5 miles north) and Crawley Museum (1.7 miles north-east). The countryside around Broadfield includes Tilgate Lake.

Doing it in-house

Redoing a failed joint normally costs more than getting it right at the outset, 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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What we are called out for in Broadfield

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.

Typical triggers for a call:

  • Hidden openings found during inspections
  • Unsealed joints where partitions meet the slab
  • Fire sealant pulled out of the opening
  • Penetration schedules that need working through

At a college such as Crawley College, 1.8 miles north-east of Broadfield, checking penetration seals after summer M&E works is good practice.

Before you book anyone

  • Will CSCS-carded applicators be on site?
  • How the existing material will be dealt with
  • How they handle RAMS and site documents
  • How they’ll work around occupants

Questions to ask before you appoint anyone

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If neighbouring businesses or buildings around Broadfield need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance
