Fire stopping for businesses in Afton

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

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

About our fire stopping in Afton

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, speak to us on 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads, and what we are called in for most is old intumescent sealant that has split away and openings found when ceilings come down for a refit. One point of contact handles commercial sealant work in Afton from the first photos to the final walk-round, for single jobs and planned programmes alike.

Around smaller places like Afton, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When something else is needed

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

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire risk assessments, a job for a competent assessor
  • Approving the work on behalf of building control

If you’re not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer.

What we seal

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

Fire stopping around Afton: how the place shapes the job

In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. A number of hotels sit less than 2 miles from Afton. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

For a school such as All Saints Church of England Primary School, penetration sealing fits best at the end of the summer works. In a building such as St. Agnes' Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hotels such as Albion Hotel (under half a mile south-west of Afton) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Afton is about 6 miles south of Lymington, in the Isle of Wight. Our applicators travel to Afton for work on service penetrations. Afton is one of 125 places we cover in the Isle of Wight for service penetrations. Southampton is covered too, around 18 miles from Afton.

Work on service penetrations is covered throughout PO40. If your site is on Bay Road, Afton Road and Manor Road or close by, we can quote for service penetrations. Sites close to Afton are covered too, including Afton Park (1 mile east), Easton (1 mile west), Freshwater (1 mile north-west), Norton Green (1 mile north) and Colwell (1 mile north-west). A short drive away, we cover Newport (9 miles east), Ryde (15 miles east), Cowes (10 miles north-east), Sandown (15 miles east), Shanklin (15 miles east) and Ventnor (14 miles south-east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Near you in Afton

Recent enquiries here include premises near The Red Lion pub and the streets around them. A little further out are Dimbola Museum And Galleries (less than half a mile south-west) and Yarmouth Castle (2.2 miles north). For a walk, there’s Afton Down and Lymington and Keyhaven Marshes Nature Reserve.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • The size and state of each joint
  • Working within restricted access windows
  • The site’s rules and procedures
  • Access and working height

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Details that help us quote

However big the job, the same details help:

  • Your programme or deadline
  • Access details, including height
  • The asbestos register, for older buildings
  • Specification clauses that apply

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, phone 01277 525 020 or use the quote form.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Afton need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Point out parking and an unloading spot
  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs

Questions we are asked in Afton

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is Afton too small for you to travel to?

No. Places such as Afton are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How long does a job like this take?

It depends on the scope, but the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Different surfaces, different methods

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.

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.
