Fire stopping for Hungerford sites

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

How we handle fire stopping in Hungerford

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are fire seals cut back for extra cables and never reinstated and service penetrations left open after M&E works. A specialist sealant contractor works differently from a general builder: on jobs in Hungerford, preparation and product choice get the time they need.

Around Hungerford, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Keeping the joints sound

To get the most from the new sealant:

  • Keep general-purpose fillers away from compartment walls
  • Keep product data and details in the fire safety file
  • Ask the designer to confirm details early on refits
  • Check risers and ceiling voids after each round of works

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Access and working height
  • The size and state of each joint
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • What the building is and how it’s used
  • Access details, including height
  • Drawings or a marked-up plan, if available
  • Any specification or named product

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

When to call us in Hungerford

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.

Things that normally lead to an enquiry:

  • Improvised or mixed-product fire seals
  • Old intumescent sealant that has split away
  • Hidden openings found during inspections
  • Non-fire-rated filler around services

Hotels such as Three Swans Hotel, under half a mile to the north-east of Hungerford, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Comparing quotes

  • The terms of the workmanship guarantee
  • How the joint faces will be prepared and primed
  • What level of public liability insurance do they hold?
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

Penetration seals near Hungerford

Approved Document B is the English guidance that covers fire stopping around 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. What we install is set by the specification, and it goes in to the tested detail. Hungerford has a number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Holiday works at schools like Hungerford Primary School often leave service openings to seal before pupils return. On estates like Hungerford Trading Estate, less than half a mile to the west of Hungerford, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Several jobs near Hungerford can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions
  • Send asbestos survey details if the building is pre-2000

Your questions answered

Do you seal service penetrations in hotels around Hungerford?

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

Can you work at a site such as Hungerford Trading Estate, by Hungerford?

Yes, sites like Hungerford Trading Estate are within our area, along with the rest of Hungerford. Photos and a short description are enough for a first look.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Are you insured?

Yes. We are fully insured, including public liability cover.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

When is resealing likely to be due?

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

How the job changes by surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.

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 something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Writing the fire-stopping specification
  • Walls or floors that aren’t fire-resisting to begin with
  • Plastic pipes whose detail calls for a collar or wrap

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Where we work in Hungerford

  • Service gaps in risers
  • Joints between fire-resisting walls and floors
