Fire stopping in Haslemere

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

Leave it or put it right?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Small buildings around Haslemere suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why appoint us

  • Constructionline member for supplier checks
  • Fully insured, including public liability cover
  • Workmanship guaranteed for 12 months
  • Products installed to the manufacturer’s instructions

Fire stopping in Haslemere

Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. If you are dealing with old intumescent sealant that has split away and seals disturbed by maintenance and left open, we can help, on service gaps in risers, pipe penetrations and cable penetrations alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Haslemere is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Haslemere, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

When to call us in Haslemere

Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.

What tends to prompt an enquiry:

  • Head-of-wall gaps with no fire seal
  • Damaged fire seals in risers and voids
  • Fire sealant pulled out of the opening
  • Hidden openings found during inspections

Older community buildings such as Church of St Christopher that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

How to choose a sealant contractor

What affects the price in Haslemere

What shapes the price:

  • How much existing material needs removing
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses
  • Access and working height

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

What we need to price the job

To price the job accurately, we need to understand the site. Send us:

  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • Where the site is, with the postcode

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If neighbouring businesses or buildings around Haslemere need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. 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

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Clear stock, furniture or equipment away from the joints

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Fire-rated sealing for Haslemere buildings

At about 39 miles from central London, Haslemere is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around 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. We install whatever has been specified, to the product’s tested detail.

Hospital estates such as Haslemere & District Hospital, 0.7 miles north-east of Haslemere, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a school such as Shottermill Infant School, penetration sealing fits best at the end of the summer works.

Haslemere is about 11 miles south of Aldershot, in Surrey. We cover Haslemere and the rest of Surrey, with the same fixed quotes and 12-month guarantee as everywhere else.

Questions we are asked in Haslemere

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Haslemere?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Will you work in a care home in Haslemere without moving residents out?

Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.

How do I request a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Include photographs or drawings if you have them.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How the job changes by surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness first.

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables, so we check before sealing.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Construction that lacks the fire resistance the seal relies on
  • Large openings beyond what any sealant detail covers

If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Joints between fire-resisting walls and floors
  • Cable penetrations
  • Linear gaps at wall heads
  • Pipe penetrations
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows
