Fire rated sealant in Hampstead Norreys, done properly

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. Common call-outs are for open joints along the top of partitions and ordinary sealant used where a fire-rated product was needed, on linear gaps, pipe & cable gaps and service penetrations.

In a village or hamlet like Hampstead Norreys, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

Whatever the size of the job, you get the same 12-month guarantee.

What happens if it’s left?

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Around Hampstead Norreys, older homes often have timber in their floors and frames, where water from a failed joint can cause rot 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. We give a clear quote before we start.

What you get with us

  • 20+ years of sealant experience
  • Every job guaranteed for a year
  • Any old sealant cut out fully, not covered over
  • Quality sealants from Arbo and Everbuild

Do you cover smaller places like Hampstead Norreys?

Yes, Hampstead Norreys is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you do fire sealant around door frames?

In most cases you can choose. We will tell you which colours the right product comes in.

Can you tell me which gaps need fire stopping?

No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.

What information do you need?

A short description and the location. If we need more, we’ll ask.

Where are you based?

We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Is it messy?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

What the job involves on each surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before we start.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.

Work for landlords, hotels and businesses

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

We also work for property managers and facilities teams. Several sites can go on one quote.

Workplaces and buildings in Hampstead Norreys

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Do you need fire rated sealant in Hampstead Norreys?

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common.

It’s worth asking for a quote if you see:

  • Old fire sealant that has split or come away
  • Gaps filled with a product that isn’t fire-rated
  • Open holes round services passing through fire walls
  • New service routes left unsealed after building work

Managing a site like Hampstead Norreys C.E. Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

10 questions to ask before booking

The process

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Hampstead Norreys, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Clear items away from the joints we’re working on
  • Let us know about parking restrictions

Advice

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Include hidden areas like risers in routine checks
  • Photograph sealed gaps before they’re covered up
  • Report cracked or damaged seals as soon as you notice them
  • Ask which product was used before you paint

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

An open gap is not only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.

When something else is needed

We will not take on work that won’t last, so these are the limits:

  • Walls or floors that weren’t built to resist fire
  • Doors that aren’t fire doors in the first place
  • Sign-off of the building, which sits with building control or your assessor

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
