Fire rated sealant near Broxhill

Fire rated sealant in Broxhill, done properly

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. We work on pipe & cable gaps, plasterboard & masonry and service penetrations, and common reasons people get in touch are new service routes left unsealed after building work and ordinary sealant used where a fire-rated product was needed.

If you have holiday lets, a converted barn used for business or a community building near Broxhill, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Each job carries a 12-month guarantee, large or small.

Surface by surface

Service penetrations

Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the sealant bonds.

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Make resealing part of every contractor’s brief
  • Ask which product was used before you paint
  • Flag any open gap you spot round a pipe or cable

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Fire rated sealant around Broxhill

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

In and around Broxhill, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint. If you look after a church, hall or community building such as Church of St James, service openings in its walls need the right fire-rated sealant, as in any building.

Can I do it myself?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

How we quote for fire rated sealant

Every job gets its own quote. This is what makes a difference:

  • The number and length of the joints
  • Access and height
  • Whether there’s mould to deal with
  • Any working-time requirements on site

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Helping us quote

Photos help, but a description is a good start. Please mention:

  • Where the property is
  • The rough size of the job
  • Photos by email, if that’s easy
  • If it’s domestic, commercial or a hotel

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or drop us an email.

For landlords and businesses

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Common questions in Broxhill

What guarantee comes with fire rated sealant in Broxhill?

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Will you come out to Broxhill?

Yes, Broxhill is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can tenants book the work?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Can you seal over the old sealant?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Is intumescent sealant the same as fire-rated sealant?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all.

What does fire rated sealant cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.

Do you take out the old sealant first?

Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Leave it or put it right?

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. Where a wall is exposed, as many are in small places like Broxhill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Why book with us

  • Neat joints and a tidy finish
  • Anti-fungal sanitary silicone in wet areas
  • Arbo and Everbuild products
  • A 12-month guarantee on all work

How it works

You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. Somewhere like Broxhill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • On commercial sites, let us know about site rules
  • Let us know about stairs, lifts or work at height
  • Clear the area around the work
