Fire stopping across Orchard Leigh

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What affects the price in Orchard Leigh

We price every job individually. The things that drive the figure:

  • Access and working height
  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • The size and state of each joint

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Your programme or deadline
  • The type of building and who uses it
  • Specification clauses that apply
  • Clear photographs of the problem areas

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email the details over.

Fire stopping for commercial buildings in Orchard Leigh

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on pipe penetrations, small duct penetrations where the tested detail allows and cable penetrations, and what we’re called in for most is unsealed penetrations discovered above suspended ceilings and expanding foam used as fire stopping. For commercial sealant work in Orchard Leigh, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places like Orchard Leigh, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Doing it in-house

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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

Your questions answered

Is Waterside Business Park, near Orchard Leigh, within your area?

Yes. Estates, retail parks and business parks around Orchard Leigh, Waterside Business Park among them, are all within reach. A few photos and the unit address let us price the work.

How does the move away from BS 476 affect penetration seals in Orchard Leigh?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is Orchard Leigh in your area?

Yes. Orchard Leigh falls within our area, and you can speak to us on 01277 525 020 or send photos by email to get started.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Do you offer coloured sealant?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Why act early in Orchard Leigh

Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable. Older rural buildings around Orchard Leigh move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.

Why us?

  • One contact handling all your sites
  • Fully insured, including public liability cover
  • Commercial sealant work since 2005
  • Failed material removed, not covered up

Fire stopping around Orchard Leigh: how the place shapes the job

For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. At about 26 miles from central London, Orchard Leigh is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.

Hospital estates such as Amersham Hospital, 4.5 miles to the south-west of Orchard Leigh, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Holiday works at schools like Ley Hill School often leave service openings to seal before pupils return. Residences at universities like Buckinghamshire New University (to the south-west of Orchard Leigh) have compartment walls that must be resealed whenever services change.

Orchard Leigh is about 2 miles east of Chesham, in Buckinghamshire.

Our process

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. Rural sites near Orchard Leigh may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. Unsuitable fillers and loose debris are taken out of each opening.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Advice

Surface by surface

Drylining partitions

Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness before sealing.

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.

Building owners, agents and FMs in Orchard Leigh

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
