About our fire stopping in Sholing

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance. The enquiries we see most involve fire seals cut back for extra cables and never reinstated and service penetrations left open after M&E works, on joints between fire-resisting walls and floors, cable penetrations and service gaps in risers. Whoever orders the work in Sholing, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Sholing, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

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.

Sholing: questions and answers

Can you take on a job at a hospital such as Royal South Hants 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.

Does your area include sites such as Bitterne Business Centre, near Sholing?

Yes. We cover Sholing and the area around it, including industrial estates, business parks and retail parks such as Bitterne Business Centre. A few photographs and the unit address let us price the work.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Work for main contractors and building owners

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Signing off or certifying a building’s fire stopping
  • Plastic pipes whose detail calls for a collar or wrap
  • Fire doors, dampers or other fire safety equipment

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

Surfaces we seal

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

How the quote is worked out

A fixed quote reflects the actual work. It allows for:

  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages
  • Distance, for remote addresses
  • The product specified

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • When you need the work done
  • The site address and postcode

To get a fixed quote, call the office on 01277 525 020 or send details through our quote form. You can also send details through our quote form.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Record which product was used where
  • Brief every trade that openings they make must be sealed
  • Get seals inspected before ceilings and boxing close
  • Settle who seals which penetrations at the start of a project

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If neighbouring businesses or buildings around Sholing need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  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. 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.

Preparing the site

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or email the details over.

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these and the building feels the difference. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What you get with us

  • Public liability insurance in place
  • Work to your specification and the manufacturer’s guidance
  • One contact handling all your sites
  • Constructionline member for supplier checks

Compartment walls and floors in Sholing

For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail. At about 68 miles from central London, Sholing is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

At a university such as Solent University, 2.1 miles to the west of Sholing, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Tenant changes at centres like Hedge End Retail Park (2.2 miles north-east of Sholing) often mean new services through walls between units. On a hospital site such as Royal South Hants Hospital, 2 miles to the north-west of Sholing, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Sholing is about 2 miles south-east of Southampton, in Southampton. We cover Sholing and the rest of Southampton, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Sholing is one of 30 places we cover in Southampton for service penetrations.
