Fire stopping across Holt Pound

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

Fire stopping in Holt Pound

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you have old intumescent sealant that has split away and builders’ foam or ordinary silicone in compartment walls, we can help. One point of contact handles commercial sealant work in Holt Pound from the first photographs to the final walk-round, whether it’s one building or several.

Rural conversions around Holt Pound can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Compartments and services around Holt Pound

At about 39 miles from central London, Holt Pound is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

For a unit at a site such as Grovebell Industrial Estate, 1.3 miles north-east of Holt Pound, new power or data runs between office and warehouse can breach a compartment wall. Campus buildings at universities such as University for the Creative Arts (to the north-east of Holt Pound) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Holt Pound is about 2 miles south-west of Farnham, in Hampshire. Anywhere in GU10, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Hampshire, 723 places are covered, including Holt Pound. Reading is covered too, some 19 miles away.

Postcode districts covered here: GU10 for service penetrations. Among the streets we cover are Fullers Road and The Wickets, and sites on any of them can send details for a fixed quote. If your building is just outside Holt Pound, we cover Rowledge (1 mile east), Wrecclesham (1 mile north-east), Boundstone (1 mile east), Bucks Horn Oak (1 mile south-west) and Shortheath (1 mile north-east). Nearby towns on our patch include Basingstoke (13 miles north-west), Farnborough (8 miles north), Fleet (6 miles north), Aldershot (5 miles north-east), Alton (7 miles west) and Petersfield (13 miles south).

Why act early in Holt Pound

An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Around Holt Pound, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why appoint us

  • Workmanship guaranteed for 12 months
  • CHAS accredited contractor
  • Public liability insurance in place
  • CSCS-carded applicators

Take a look at what affects the cost and how we’re accredited.

From enquiry to 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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Holt Pound are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Point out any areas we must not close
  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints

What sets the cost

To price the job, we consider:

  • Access and working height
  • Which sealant the job calls for
  • How much there is to seal
  • Distance, for remote addresses

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Whether the building will be occupied during the work
  • Clear photos of the problem areas
  • Anything awkward about access or site hours
  • Specification clauses that apply

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Reviewing a building’s overall fire safety
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Surfaces we seal

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

Holt Pound: questions and answers

What does the BS 476 change mean for fire-rated sealant in Holt Pound?

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.

Can you work around term dates at a campus such as University for the Creative Arts?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months on every job.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Do you need fire stopping in Holt Pound?

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, which then have to be put right.

Typical triggers for a call:

  • Damaged fire seals in risers and voids
  • Seals that don’t match their tested detail
  • Hidden openings found during inspections
  • Old intumescent sealant that has split away

Hospital estates such as Spire Clare Park Hospital, 2.8 miles north of Holt Pound, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid
  • Proof of insurance
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Record which product was used where
  • Check risers and ceiling voids after each round of works
  • Report damaged or disturbed seals as soon as they’re spotted

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.
