Fire stopping for Green Park sites

Fire stopping in Green Park, done properly

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Most enquiries involve openings found when ceilings come down for a refit and unsealed joints where partitions meet the slab, across joints between fire-resisting walls and floors, service gaps in risers and cable penetrations. A specialist sealant contractor works differently from a general builder: in Green Park, that means joint design, primers and backing rod as standard.

For a smaller site near Green Park, we plan to do all the penetrations in one go, 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.

Questions we’re asked in Green Park

Do you take on work at healthcare sites like Berkshire Independent Hospital?

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.

Can you seal penetrations in a hotel in Green Park after a refit?

Yes, where the specification calls for fire-rated sealant. 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.

Are you insured?

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

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Signs you need fire stopping in Green Park

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.

Look out for the following:

  • Builders’ foam or ordinary silicone in compartment walls
  • Seals disturbed by maintenance and left open
  • Hidden openings found during inspections
  • Seals that don’t match their tested detail

Hospital estates such as Berkshire Independent Hospital, 1.4 miles to the north of Green Park, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Before you book anyone

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Are they CHAS accredited or on Constructionline?
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

From enquiry to sign-off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a building around Green Park, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  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.

What we need from you

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Let building users know which areas are affected

Related advice

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Converted and older buildings near places like Green Park tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • Distance, for remote addresses
  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Phasing around occupants

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Details that help us quote

However big the job, the same details help:

  • Drawings or a marked-up plan, if available
  • The postcode of the building
  • Anything awkward about access or site hours
  • Your programme or deadline

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, speak to us on 01277 525 020 or email drawings and photos.

Fire stopping around Green Park: how the place shapes the job

A 2-mile radius around Green Park takes in a good number of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. Green Park is about 39 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.

Colleges such as Reading College, 2.6 miles to the north-east of Green Park, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For a unit at a site such as Reading Gate Retail Park, which lies east of Green Park, any new service through a fire-resisting wall should be sealed to the tested detail.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
