Fire stopping near Little Sandhurst

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

What the job involves on each surface

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

Fire stopping for commercial buildings in Little Sandhurst

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. 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. The enquiries we see most involve fire stopping installed outside its tested range and fire sealant pulled out of the opening, on small duct penetrations where the tested detail allows, cable penetrations and service gaps in risers. Whoever orders the work in Little Sandhurst, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Around Little Sandhurst, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we’ll quote to suit.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Little Sandhurst can form part of a wider programme across Bracknell Forest.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Quoting for work in Little Sandhurst

The price varies from site to site. Expect it to depend on:

  • Phasing around occupants
  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • Site requirements such as inductions and permits

A quote for service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • What the building is and how it’s used
  • The postcode of the building
  • Drawings or a marked-up plan, if available
  • The product your specification calls for

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or send photos by email to discuss it first.

When to call us in Little Sandhurst

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Common reasons buildings call us in:

  • Snag lists that include open service penetrations
  • Unsealed openings around new pipes and cables
  • Head-of-wall gaps with no fire seal
  • Builders’ foam or ordinary silicone in compartment walls

Hospital estates such as Broadmoor Hospital, 1.7 miles north-east of Little Sandhurst, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Questions about Little Sandhurst

Does your area include sites such as Wellington Business Park, near Little Sandhurst?

Yes. We cover Little Sandhurst and the area around it, including industrial estates, business parks and retail parks such as Wellington Business Park. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is Little Sandhurst too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How much does the work cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Do you design or specify fire stopping?

No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Where services cross fire walls in Little Sandhurst

In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Little Sandhurst lies roughly 32 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

Holiday works at schools like New Scotland Hill Primary School often leave service openings to seal before pupils return. Offices at parks like Wellington Business Park (0.9 miles north of Little Sandhurst) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Work in places the size of Little Sandhurst is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. First we go through the drawings, schedule or specification for the seals.
  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. Mineral wool or other backing goes in wherever the detail asks.
  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.

Preparing the site

  • Share your working hours and any access restrictions
  • Move anything stored against the joints
  • Send any specification or drawings in advance
