Fire rated sealant for Baybridge homes and businesses

Landlord and commercial work in Baybridge

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Fire rated sealant for homes and businesses in Baybridge

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you’re dealing with holes left by a change of layout and gaps flagged on a fire risk assessment, we can help, whatever the surface.

For a small place like Baybridge, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What we do, step by step

At the end, we look at the finished work together. The visit itself usually takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. In a small place like Baybridge, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products.

Before we arrive

  • Tell us about any water getting in
  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints

Advice

Your questions about fire rated sealant in Baybridge

Do you cover smaller places like Baybridge?

Yes, Baybridge is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Shawford station?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

How long does fire rated sealant take?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll say how long yours will take.

Do you certify the fire stopping?

That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. We use whichever the specification and tested details call for.

Different surfaces, different methods

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.

DIY versus a professional finish

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Leave it or put it right?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. Around Baybridge, 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 the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What affects the quote in Baybridge

Call for a quick quote. What matters most is:

  • Any mould that needs treating
  • The old material and how stubborn it is
  • The number and length of the joints
  • The type of sealant required

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

To make quoting easier, please include:

  • How we’d reach the joints
  • The address or postcode of the job
  • Whether it has been sealed before
  • The type of property

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or send us an email.

When it is not the sealant

Before booking, it’s worth knowing the limits:

  • Fire risk assessments, which need a qualified assessor
  • Large holes that need a different fire-stopping system
  • Doors that aren’t fire doors in the first place

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Commercial buildings in Baybridge

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, 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.

For landlords with property near Shawford station, any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as Owslebury Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. For buildings such as Church of St Andrew, service openings in its walls need the right fire-rated sealant, as in any building.
