Fire stopping for Soberton Heath sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Cost factors for service penetrations

A fixed quote reflects the actual work. It takes account of:

  • Any access equipment needed
  • Travel to remote or island sites
  • Phasing around occupants
  • Quantities, in metres or numbers

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Your programme or deadline
  • The asbestos register, for older buildings
  • The type of building and who uses it
  • Access details, including height

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email a schedule or drawings.

Fire stopping in Soberton Heath, done properly

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. We close the openings listed on your schedule, using the specified sealant and detail. The enquiries we see most involve seals disturbed by maintenance and left open and openings found when ceilings come down for a refit, on linear gaps at wall heads, joints between fire-resisting walls and floors and service gaps in risers. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Soberton Heath, preparation and product choice get the time they need.

Rural conversions around Soberton Heath 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.

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

Questions about Soberton Heath

Can you take on a job at a hospital such as Knowle Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Soberton Heath off your patch?

No. Places such as Soberton Heath are covered as much as the big 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.

Do you design or specify fire stopping?

No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What will the job cost?

Every job gets its own fixed quote. To get one, call 01277 525 020 or email drawings and photos.

Do you certify or sign off fire stopping?

No. Approval sits with the designer, principal designer or building control. We will confirm the product and detail installed and agree any further records when we quote.

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. If others near Soberton Heath need work, visits can be combined. A fixed quote is given before anything starts.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Advice

Why act early in Soberton Heath

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. One visit to deal with every failing joint makes more sense than several trips to a place like Soberton Heath. Photos of every joint help us quote for the whole job.

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Why us?

  • CHAS accredited contractor
  • Our applicators hold CSCS cards
  • One contact handling all your sites
  • Constructionline member for supplier checks

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Large openings beyond what any sealant detail covers
  • Writing the fire-stopping specification
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Surfaces we seal

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

Compartment walls and floors in Soberton Heath

In England, Approved Document B covers fire stopping of openings and penetrations. 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. Either way, we install the specified product to its tested detail. Central London is about 60 miles from Soberton Heath. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Halls and meeting rooms at places like Church of the Holy Trinity sometimes gain new services, and any compartment wall crossed needs the specified seal. For a building at a site such as Waltham Business Park (2.3 miles west of Soberton Heath), a check of penetration seals after each fit-out is good practice. Hospital estates such as Knowle Hospital, 4.1 miles to the south-west of Soberton Heath, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Soberton Heath is about 5 miles north-west of Waterlooville, in Hampshire. Across the SO32 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Our Portsmouth page has more on work in that area, about 8 miles away.

Postcode districts covered here: SO32 and PO17. We cover commercial and managed buildings on Forester Road, May Bush Lane and Heath Road. We also cover Southend (1 mile east), Woodend (1 mile west), Newtown (1 mile south), Kingsmead (1 mile west) and Mislingford (1 mile west) for service penetrations. Nearby towns on our patch include Winchester (12 miles north-west), Gosport (8 miles south), Havant (8 miles south-east), Eastleigh (10 miles west), Fareham (6 miles south-west) and Horndean (6 miles east).

Local landmarks in Soberton Heath

What the job involves on each surface

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.

Looking after the joints

A few simple habits keep the new joints working:

  • Look above ceilings when tiles are lifted for other jobs
  • Keep general-purpose fillers away from compartment walls
  • Ask which product is in place before decorating
  • Get seals inspected before ceilings and boxing close

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.
