Fire rated sealant for homes and businesses in Pett

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on pipe & cable gaps, flats & HMOs and linear gaps, and the jobs we see most are ordinary sealant used where a fire-rated product was needed and gaps where walls meet ceilings or slabs.

Work in a small place like Pett is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How the visit works

We keep the work tidy and contained to the area we are working on. Expect the work to take anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. In a small place like Pett, 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. Dust and loose debris are cleaned from each gap.
  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.

How to prepare

  • Mention if the joints have been sealed before
  • For indoor joints, keep the area dry beforehand if you can
  • Plan for the work area to be out of bounds to pets and children

What the job involves on each surface

Plasterboard walls

We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified room by room.

Commercial buildings in Pett

If you run a hotel, guest house or holiday let in a coastal place like Pett, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

For landlords with property near Three Oaks station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a church, hall or community building such as St Mary & St Peter, gaps around pipes and cables are worth checking after any building work there.

Can you do fire rated sealant in Pett?

Yes. Our work covers London and the South East, and Pett is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

Are you fully insured?

Yes, we’re fully insured for domestic and commercial work.

How long does fire rated sealant take?

That depends on how much there is to do, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.

Is it OK to seal over old sealant?

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

Is there any odour?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Is standard sealant good enough for a fire gap?

No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.

Can you match the sealant colour?

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

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

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

How to look after the new joints

Simple care keeps the joints in good condition. Our advice:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Tell trades working in the building that fire seals must be put back
  • Flag any open gap you spot round a pipe or cable
  • Keep pictures of seals that will be hidden

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
