Fire rated sealant in Maplehurst

FAQs for Maplehurst

Will you come out to Maplehurst?

Yes, we do. 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.

Can you do fire rated sealant in Maplehurst?

Yes. Our work covers London and the South East, and Maplehurst is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.

Can new sealant go over the old?

No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

What sealant do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Do you provide details of the products used?

Yes. We note each location and the product that went in so it’s there for the next inspection.

Do you work in flats, HMOs and commercial buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we’ll plan around it.

Will the old sealant be removed?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

How we handle fire rated sealant in Maplehurst

We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We work on pipe & cable gaps, linear gaps and service penetrations, and common reasons people get in touch are sealant items on a fire risk assessment action list and cracked or shrunken fire-rated sealant.

For holiday lets, converted business premises or a community building near Maplehurst, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

A 12-month guarantee comes as standard.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Looking after it afterwards

After the cure time, these simple habits help:

  • Allow for resealing whenever new services are run
  • Photograph sealed gaps before they’re covered up
  • Keep the record of products and locations with your fire safety documents
  • Include hidden areas like risers in routine checks

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

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.

Leave it or put it right?

For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we will tell you. Where a wall is exposed, as many are in small places like Maplehurst, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

For landlords and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

How the visit works

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Maplehurst, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  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 for your files.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Mention any tricky access
  • Clear items away from the joints we are working on

What we’re called out for in Maplehurst

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.

The most common problems we see are:

  • Open joints along the top of partitions
  • Open gaps behind door architraves
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps left after a refit or conversion

For buildings such as The Parish Church of St Andrew, gaps around pipes and cables are worth checking after any building work there.

What the job involves on each surface

Door frames

A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
