Fire stopping for Great Holland sites

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

Fire stopping in Great Holland, done properly

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you are dealing with fire-rated sealant that has cracked or shrunk back and fire stopping installed outside its tested range, we can put it right. Whoever orders the work in Great Holland, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A job near Great Holland is normally planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right

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

  • Approving the work on behalf of building control
  • Gaps in walls that were never built as compartment walls
  • Large openings beyond what any sealant detail covers

If you are not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer.

Joints and surfaces we work on

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

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Building owners, agents and FMs in Great Holland

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Compartment walls and floors in Great Holland

In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Great Holland has three care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

Hotels such as Linnets Hotel (to the north-east of Great Holland) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Schools such as Kirby Primary Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Great Holland is about 3 miles north-east of Clacton-on-Sea, in Essex. Businesses, contractors and managing agents in Great Holland can call on us for service penetrations. Our Essex coverage takes in 644 places. London is covered too, some 61 miles away.

Postcode districts covered here: CO13 for service penetrations. If your site is on Rosery Mews, Orchard Drive and Laxton Grove or close by, we can quote for service penetrations. Nearby places we also cover include Kirby Cross (1 mile north-east), Kirby-le-Soken (1 mile north-east), Thorpe Cross (2 miles north-west), Lane End (2 miles north) and Frinton-on-Sea (2 miles east). Bigger towns within reach include Colchester (14 miles west), Clacton-on-Sea (3 miles south-west), Harwich (7 miles north), Camulodunum (15 miles west), Greenstead (12 miles west) and Wivenhoe (11 miles west).

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Smaller jobs around Great Holland can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000
  • Point out parking and an unloading spot

Ask for a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Questions we are asked in Great Holland

Can you work at a site such as Lodge Farm Business Park, by Great Holland?

Yes. Our area takes in Great Holland and its surroundings, with estates and business parks such as Lodge Farm Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is Great Holland off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What do you charge?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Which standards are fire seals tested to?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2. That rating only holds when the product is installed to its tested detail.

Leave it or put it right?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Halls, stores and units around places like Great Holland may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What we’re called out for in Great Holland

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

If one of these sounds familiar, it’s time for a closer look:

  • Unsealed penetrations discovered above suspended ceilings
  • Fire sealant pulled out of the opening
  • Snag lists that include open service penetrations
  • Fire stopping installed outside its tested range

Offices at parks like Lodge Farm Business Park (to the south of Great Holland) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

What your quote should include

  • Whether primer will be used where the manufacturer specifies it
  • Will failed sealant be removed rather than covered?
  • Whether their applicators hold CSCS cards
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
