Trusted fire rated sealant in Twyford

Fire rated sealant in Twyford, done properly

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Typical jobs include gaps filled with a product that isn’t fire-rated and seals cut through by electricians, plumbers or data installers, across pipe & cable gaps, flats & HMOs and linear gaps.

Work in a small place like Twyford is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

Whatever the size of the job, it’s backed by our one-year guarantee.

What happens if it’s left?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Twyford, 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 depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Work for landlords, hotels and businesses

We also work for property managers and facilities teams in Twyford and across Buckinghamshire. We can quote a run of properties together.

What sealant work can’t fix

Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:

  • Openings too large for sealant, which need batts, boards or another system
  • Certifying a building or signing off its fire safety
  • Assessing a building’s fire safety

If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.

Surfaces we seal

  • Linear gaps
  • Door frames
  • Pipe & cable gaps
  • Plasterboard & masonry

Your questions about fire rated sealant in Twyford

Do you cover Twyford for fire rated sealant?

Yes. We work across London and the South East, and Twyford is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.

Will you come out to Twyford?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you take on fire stopping in schools and offices?

Yes. Occupied flats, HMOs, offices and schools are all fine. Out-of-hours work can be arranged.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.

Can you do several jobs on one visit?

Yes. More than one area can go on one quote.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Do you seal gaps around fire door frames?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

Fire rated sealant around Twyford

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’re given, installing the product to its tested details.

For site and facilities teams at buildings such as Twyford C of E School, gaps opened by contractors for new cabling are a common finding in schools and offices.

What affects the quote in Twyford

Jobs vary more than people expect. The main factors:

  • The number of rooms or windows

  • How much there is to do
  • How easy the joints are to reach

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.

Photos by email are helpful but not essential. Try to tell us:

  • Whether it has been sealed before
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel
  • Where the property is

When to call us in Twyford

Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Any of these means the joints need attention:

  • Gaps around pipes and cables through fire-resisting walls
  • Open gaps behind door architraves
  • Seals cut through by electricians, plumbers or data installers
  • New service routes left unsealed after building work

In and around Twyford, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

The process

All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Twyford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep pets and children clear of the area while we work
  • Mention any parking rules near the property

How to get a quote

Can I do it myself?

If you’ve already had a go yourself, that is fine. We cut it out and start again.

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