Fire rated sealant for Lane End homes and businesses

How we handle fire rated sealant in Lane End

We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. Typical jobs include gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap, across service penetrations, flats & HMOs and plasterboard & masonry.

For a small place like Lane End, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

There’s a 12-month guarantee on every job, whatever its size.

What the job involves on each surface

Service penetrations

Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Leave it or put it right?

A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In a small place like Lane End, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Honest limits

New sealant can’t fix everything, and we will tell you before we start. It will not solve:

  • Walls or floors that weren’t built to resist fire
  • Doors that are not fire doors in the first place
  • Issuing a fire rating or certificate for a building

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

What fire rated sealant looks like in Lane End

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 jobs in and around Lane End, choosing the right material for each joint is as important as a tidy finish.

Signs you need fire rated sealant in Lane End

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Any of these means the joints need attention:

  • Gaps around pipes and cables through fire-resisting walls
  • Unsealed gaps around fire door frames
  • Damaged fire sealant left by other trades
  • Holes left by a change of layout

Around Lane End, as everywhere, fire rated sealant is only as good as the preparation behind it.

How to choose a mastic man

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you do try it yourself, take your time over the 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.

Lane End: your questions answered

Will you come out to Lane End?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is fire rated sealant in Lane End guaranteed?

All our work, in Lane End and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Is it messy?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

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. The order of work and access are planned with you.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

What we do, step by step

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Lane End, the journey is planned in advance: 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. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks
  • Keep children and pets away from the work area
