Fire rated sealant near Corhampton

Leave it or put it right?

Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Around Corhampton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Why us?

  • We never seal over old sealant
  • Every job guaranteed for a year
  • Full insurance on every job
  • Neat joints and a tidy finish

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

When it is not the sealant

We won’t take on work that won’t last, so here’s what sealant can’t put right:

  • Openings too large for sealant, which need batts, boards or another system
  • Deciding what fire stopping a building needs
  • Walls or floors that weren’t built to resist fire

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Surfaces we seal

  • Plasterboard & masonry
  • Door frames
  • Service penetrations
  • Pipe & cable gaps
  • Linear gaps
  • Flats & HMOs

Fire rated sealant in Corhampton: local notes

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

If you look after a building such as Meonstoke Church of England Infant School, fire-stopping around service openings should be restored whenever new services go in.

How the visit works

At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually 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 small place like Corhampton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  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. Locations and products are noted so you have them on file.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height

Questions from Corhampton

Is Corhampton within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is Corhampton in your area for fire rated sealant?

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

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.

What does intumescent mean?

An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status.

Can I choose the sealant colour?

Most of the time, yes. We’ll explain which colours are available and agree one before we start.

Looking after it afterwards

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

  • Include fire stopping when you schedule refits
  • Take pictures of fire stopping before ceilings or boxing go back
  • Report cracked or damaged seals as soon as you notice them
  • File the fire-stopping record where your assessor can find it

Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Landlords, agents and businesses in Corhampton

If you manage several properties in or around Corhampton, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Do you need fire rated sealant in Corhampton?

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

Signs it’s time to call us include:

  • Gaps left after a refit or conversion
  • Unsealed gaps around fire door frames
  • Gaps where walls meet ceilings or slabs
  • Open holes round services passing through fire walls

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