Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Ask which product was used before you paint
  • Take pictures of fire stopping before ceilings or boxing go back
  • Plan fire stopping into any work that goes through walls or floors
  • Report cracked or damaged seals as soon as you notice them

Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Fire rated sealant in Horsebridge

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. If you’re dealing with gaps left after a refit or conversion and gaps flagged on a fire risk assessment, we can help.

For a small place like Horsebridge, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Fire rated sealant in Horsebridge: local notes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

For buildings such as Church of St James, gaps around pipes and cables are worth checking after any building work there. Rented homes near Mottisfont & Dunbridge station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For site and facilities teams at buildings such as King's Somborne Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Horsebridge is about 5 miles north of Romsey, in Hampshire. Every kind of property in Horsebridge can book us for fire rated sealant. The work is guaranteed for a year. Horsebridge is one of 683 towns and villages in Hampshire where we work for fire rated sealant. For nearby work, see our Southampton page.

Why it’s worth doing now in Horsebridge

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Around Horsebridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

It helps to know what we cannot do:

  • Doors that aren’t fire doors in the first place

Do you cover Horsebridge for fire rated sealant?

Yes, Horsebridge is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Do you take on fire stopping in schools and offices?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

What do you need from me for a quote?

Let us know what needs doing and where. If we need more, we will ask.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Is the work guaranteed?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Do you hold any approvals?

Yes. We are approved under the ARBOMaster scheme.

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The process

On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Horsebridge needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Getting ready for the visit

  • Mention if the joints have been sealed before
  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area

Advice

What affects the cost of fire rated sealant

There’s no set price list. What we look at:

  • The number and length of the joints
  • Mould in or behind the old joints
  • Any working-time requirements on site
  • Access and height

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Asking for a quote

Before you ask for a quote, have a think about:

  • Where the job is, and your postcode
  • Any access issues, like height or stairs
  • What’s wrong with the joints now
  • If someone has resealed it before

Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

How the job changes by surface

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.

Masonry and concrete

Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.
