Fire stopping for Weston sites

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

Different surfaces, different methods

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables.

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.

How we handle fire stopping in Weston

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. Most enquiries involve damaged fire seals in risers and voids and snag lists that include open service penetrations, across joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows. For commercial sealant work in Weston, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a smaller site near Weston, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Where services cross fire walls in Weston

Weston is about 51 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. There are several hotels within about 2 miles of Weston. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

Hotels like The Red Lion Hotel, 1.5 miles north-east of Weston, are refurbished in phases, and each phase can open up compartment walls. Schools such as Buriton Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Weston is about 1 mile south-west of Petersfield, in Hampshire. Anywhere in GU32, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Weston is one of 723 places we cover in Hampshire. Our Portsmouth page has more on work in that area (14 miles or so).

Anyone looking for fire stopping in GU32 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on Weston Lane and Wylds Lane or nearby, send details and we will quote for service penetrations. Sites close to Weston are covered too, including Buriton (1 mile south-east), Ramsdean (1 mile west), Nursted (2 miles east), Chalton (4 miles south) and Blendworth (5 miles south). Nearby towns on our patch include Gosport (15 miles south-west), Havant (9 miles south), Fareham (14 miles south-west), Horndean (6 miles south), Alton (11 miles north) and Waterlooville (8 miles south-west).

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Weston are typically planned as a single 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. 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. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  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.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we will be in

When to call us in Weston

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

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

  • Openings found when ceilings come down for a refit
  • Head-of-wall gaps with no fire seal
  • Non-fire-rated filler around services
  • Seals that don’t match their tested detail

Theatres, wards and plant rooms at sites like Petersfield Hospital (1.2 miles north-east of Weston) all have compartment walls crossed by services.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • How they’ll work around occupants
  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Ask the designer to confirm details early on refits
  • Brief every trade that openings they make must be sealed
  • Foam or ordinary sealant is never a fire-seal repair
  • Treat an open penetration as a priority repair

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Quoting for work in Weston

Before we quote, we look at:

  • Phasing around occupants
  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • When you need the work done
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Questions we’re asked in Weston

Can you work on a hospital site such as Petersfield Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Weston off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

How much does the work cost?

Every job gets its own fixed quote. For yours, ring 01277 525 020 or send details through our quote form with a description of the work.

How many days will you need on site?

It depends on the scope, but the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
