Fire rated sealant near Bromley Common

Fire rated sealant in Bromley Common

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 old fire sealant that has split or come away, on service penetrations, door frames and pipe & cable gaps.

In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Bromley Common.

There’s a 12-month guarantee on every job.

Leave it or put it right?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Bromley Common, the repair is bigger than the sealant job would have been.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

What you get with us

  • Neat joints and a tidy finish
  • A 12-month guarantee on all work
  • Full insurance on every job
  • An ARBOMaster approved applicator

Take a look at our cost guide and what customers say.

What affects the cost of fire rated sealant

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

  • The type of sealant required
  • Whether the work is at height
  • How many rooms, windows or areas are involved
  • The number and length of the joints

Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

What we need to know

To make quoting easier, please include:

  • The type of property
  • The rough size of the job
  • Where the job is, and your postcode
  • What the problem is, such as mould, gaps, leaks or cracking

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or drop us an email.

Bromley Common: your questions answered

Can you do fire rated sealant in Bromley Common?

Yes. Our work covers London and the South East, and Bromley Common is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.

Do you work for landlords with property near Bickley station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.

What does fire rated sealant cost?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator.

What’s the difference between intumescent and fire-rated sealant?

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

Are you fully insured?

Yes. We’re fully insured, with over 20 years’ experience in sealant work.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Do I need to be at home?

If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.

Work for landlords, hotels and businesses

Letting agents and landlords in Bromley Common can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What fire rated sealant looks like in Bromley Common

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. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.

For buildings such as Holy Trinity Church, gaps around pipes and cables are worth checking after any building work there. For landlords with property near Bickley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Bromley Common is about 2 miles south-east of Bromley, in Greater London.

Different surfaces, different methods

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.

What we’re called out for in Bromley Common

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps filled with a product that isn’t fire-rated
  • Gaps around pipes and cables through fire-resisting walls
  • Gaps flagged on a fire risk assessment
  • Gaps left after a refit or conversion

Bromley Common is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Before booking anyone

  • The length of the guarantee
  • What product goes in the joint
  • How the surfaces are prepared before sealing
  • Whether you can choose the colour

Our hiring checklist

Aftercare tips

A little care helps the new joints last. Our advice:

  • Store the list of sealed gaps with your building paperwork
  • Never patch a fire seal with standard sealant
  • Look in service cupboards and ceiling voids from time to time
  • Check whether a sealant can be painted before decorating over it

Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.

What we do, step by step

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. In a London area like Bromley Common, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts
