Fire stopping in East Grinstead

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

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • How accessible the joints are
  • Joint width, depth and condition

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

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

  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Clear photos of the problem areas
  • Any specification or named product

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, phone 01277 525 020 or email the details over.

Fire stopping in East Grinstead, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on cable penetrations, pipe penetrations and joints between fire-resisting walls and floors, and what we are called in for most is hidden openings found during inspections and builders’ foam or ordinary silicone in compartment walls. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in East Grinstead, that means joint design, primers and backing rod as standard.

Older buildings in towns like East Grinstead have often been rewired and replumbed several times, and each change can leave unsealed holes in walls and floors. Intumescent or fire-rated sealant is used wherever the specification asks for it, built up exactly as tested.

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

FAQs: East Grinstead

Do you work on fire-rated sealing in hotels in East Grinstead?

Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.

Do you take on work at healthcare sites like Queen Victoria Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Service penetrations in East Grinstead buildings

There are several hotels within about 2 miles of East Grinstead. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. 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.

Older community buildings such as Our Lady and St Peter's Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Offices at parks like Bulrushes Farm Business Park, 0.9 miles south of East Grinstead, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. For a hotel such as Crown Hotel, which lies south-east of East Grinstead, penetration seals are worth checking after any refit or services upgrade.

Different surfaces, different methods

Metal pipes

Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Construction that lacks the fire resistance the seal relies on
  • Approving the work on behalf of building control

If in doubt, ring 01277 525 020 or email us and we’ll say what we think.

Surfaces we seal

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

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In a town such as East Grinstead, most jobs are single buildings. Your photographs, drawings or a site visit come first, followed by a fixed quote.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  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. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Let building users know which areas are affected
  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints

Quotes

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email drawings and photos.

Advice

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

For managing agents and facilities managers

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around East Grinstead. Several sites can go on one quote, which keeps the paperwork simple.
