Fire stopping for Lower Froyle sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Lower Froyle, done properly

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you’re dealing with seals that don’t match their tested detail and fire seals cut back for extra cables and never reinstated, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lower Froyle, that means joint design, primers and backing rod as standard.

A job near Lower Froyle is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

FAQs: Lower Froyle

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

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can you work at a site such as Bentley Business Park, by Lower Froyle?

Yes. Our area takes in Lower Froyle and its surroundings, with estates and business parks such as Bentley Business Park included. A few photographs and the unit address let us price the work.

How long does a typical visit take?

It depends on the scope, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Does weather matter for sealant work?

It can, when the joints are outside. 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.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

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

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Phasing around occupants
  • Travel to remote or island sites
  • Removal of failed or old sealant
  • Backing rod, priming and other preparation

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • The product your specification calls for
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older

To get a fixed quote, phone 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.

When to call us in Lower Froyle

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.

Site and facilities staff are often the first to spot these:

  • Improvised or mixed-product fire seals
  • Hidden openings found during inspections
  • Head-of-wall gaps with no fire seal
  • Openings left by services added after handover

On a site such as Bentley Business Park, which lies east of Lower Froyle, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What your quote should include

  • What level of public liability insurance do they hold?
  • Their approach to joint depth and backing
  • Who will actually carry out the work
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Approving the work on behalf of building control
  • Construction that lacks the fire resistance the seal relies on
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Lower Froyle can sit alongside others in a wider programme.

If you look after buildings for someone else, 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.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Record which product was used where
  • Brief every trade that openings they make must be sealed
  • Flag new cables with no seal around them
  • Agree the fire-stopping specification before services go in

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

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

Compartments and services around Lower Froyle

Two care or nursing homes sit less than 2 miles from Lower Froyle. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified. 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. We install whatever has been specified, to the product’s tested detail.

In a building such as Church of St Mary of the Assumption, any service penetration through a fire-resisting wall should be sealed to the specified detail. At a healthcare site like Alton Community Hospital, 4.8 miles to the south-west of Lower Froyle, new services through compartment walls are a constant, and each needs the specified seal.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Rural sites near Lower Froyle may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out 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

  • Tell us which areas need to stay in use
  • Make sure the joints can be reached
  • Point out parking and an unloading spot
