Fire stopping near Bursledon

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

Where services cross fire walls in Bursledon

The 2 miles around Bursledon include five care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need 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. Either way, we install the specified product to its tested detail.

For an estates team at a campus like Solent University, 4 miles west of Bursledon, summer M&E works are usually followed by a round of penetration sealing. Older community buildings such as St Paul’s Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Theatres, wards and plant rooms at sites like Fareham Community Hospital, 2.1 miles south-east of Bursledon, all have compartment walls crossed by services.

Bursledon is about 2 miles south of Hedge End, in Hampshire. We cover commercial sites throughout Bursledon, for single jobs and planned programmes alike. Across Hampshire, 723 places are covered, including Bursledon.

Fire stopping in Bursledon

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. Those on your schedule are closed with the specified product. We work on linear gaps at wall heads, service gaps in risers and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are fire-rated sealant that has cracked or shrunk back and seals that don’t match their tested detail. For commercial sealant work in Bursledon, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Buildings in a smaller place such as Bursledon that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Different surfaces, different methods

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.

Questions we are asked in Bursledon

Can you work around term dates at a campus such as Solent University?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

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

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can weather delay the job?

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.

Do you have third-party installer accreditation for fire stopping?

No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.

Can you tell us what fire stopping our building needs?

No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

What affects the price in Bursledon

What shapes the price:

  • The product specified
  • Distance, for remote addresses
  • Joint width, depth and condition
  • Induction, permit and paperwork requirements

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Any specification or named product
  • Your programme or deadline

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email a schedule or drawings to discuss it first.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Looking after the joints

A few simple habits keep the new joints working:

  • Keep general-purpose fillers away from compartment walls
  • Look above ceilings when tiles are lifted for other jobs
  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep product data and details in the fire safety file

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. If neighbouring businesses or buildings around Bursledon need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use
