Need fire stopping in Mislingford?

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

Why it’s worth doing now in Mislingford

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Around Mislingford, 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.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why us?

  • Fixed quotes based on photos, drawings or a visit
  • Health and safety: CHAS accredited
  • Our applicators hold CSCS cards
  • Constructionline member

How we handle fire stopping in Mislingford

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call the office on 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and what we are called in for most is hidden openings found during inspections and damaged fire seals in risers and voids. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Mislingford, preparation and product choice get the time they need.

A job near Mislingford is usually planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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

Maintenance after handover

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

  • Keep general-purpose fillers away from compartment walls
  • Check with the data sheet before painting over fire sealant
  • Settle who seals which penetrations at the start of a project
  • Keep product data and details in the fire safety file

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Mislingford may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  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.

What we need from you

  • Send any specification or drawings in advance

What affects the price in Mislingford

Quotes vary with the job. Expect it to depend on:

  • The site’s rules and procedures
  • Which sealant the job calls for
  • Backing rod, priming and other preparation
  • How accessible the joints are

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • Clear photographs of the problem areas
  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email us to discuss it first.

Fire-rated sealing for Mislingford buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. There are a number of hotels within about 2 miles of Mislingford. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

At a healthcare site like Knowle Hospital (3.6 miles south-west of Mislingford), new services through compartment walls are a constant, and each needs the specified seal. For a building at a site such as Waltham Business Park, 1 mile north-west of Mislingford, a check of penetration seals after each fit-out is good practice. For a school such as Swanmore College of Technology, penetration sealing fits best at the end of the summer works.

Mislingford is about 5 miles north of Fareham, in Hampshire. If you’re looking for fire stopping in Mislingford, we can help. We work across 723 places in Hampshire. Our Portsmouth page has more on work in that area, about 9 miles away.

Work on service penetrations is covered throughout PO17, whatever the building. We also cover Kingsmead (1 mile south), Woodend (1 mile south-east), Hill Grove (1 mile north), Shirrell Heath (1 mile west) and Swanmore (1 mile north-west) for service penetrations. Bigger towns within reach include Winchester (11 miles north-west), Gosport (9 miles south), Havant (9 miles south-east), Eastleigh (8 miles west), Fareham (5 miles south) and Horndean (7 miles east).

Mislingford: questions and answers

How does the move away from BS 476 affect penetration seals in Mislingford?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is a smaller place like Mislingford outside your area?

No. Places such as Mislingford are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Can you quote from photos?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
