Fire rated sealant in Calcot

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. If you have gaps where walls meet ceilings or slabs and gaps filled with a product that isn’t fire-rated, we can help.

Around a place like Calcot, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.

Big or small, it’s backed by our one-year guarantee in Calcot and across West Berkshire.

Do you need fire rated sealant in Calcot?

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.

Look out for these signs:

  • Gaps around pipes and cables through fire-resisting walls
  • Open joints along the top of partitions
  • Ordinary sealant used where a fire-rated product was needed
  • Fire seals that have cracked with movement

For landlords with property near Theale station, any gap left by new services in shared walls should be closed with a fire-rated product.

How to choose a mastic man

What sealant work cannot fix

It helps to know what we can’t do:

  • Big openings where sealant alone is not the tested solution
  • Walls or floors that weren’t built to resist fire
  • Fire risk assessments, which need a qualified assessor

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Surfaces we seal

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

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. It usually takes from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Calcot, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks
  • Let us know about stairs, lifts or work at height

Quotes for fire rated sealant in Calcot

Your quote is based on your job. We take into account:

  • The type of sealant required
  • How many areas need sealing
  • Any working-time requirements on site
  • Whether there’s mould to deal with

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • What’s wrong with the joints now
  • If someone has resealed it before
  • Pictures of the joints, sent by email
  • The type of property

We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job.

Should I try it myself first?

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What happens if it’s left?

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In an older home around Calcot, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Different surfaces, different methods

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Workplaces and buildings in Calcot

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

For site and facilities teams at buildings such as Calcot Infant School and Nursery, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of St Michael, older buildings that have had new heating or wiring often have service gaps worth checking.

Your questions about fire rated sealant in Calcot

Is Calcot within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Calcot for fire rated sealant?

Yes, Calcot is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.

Is standard sealant good enough for a fire gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.

What’s the difference between intumescent and fire-rated sealant?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.

How long does fire rated sealant take?

Most jobs take anything from a few hours to several days, depending on how many gaps there are, including preparation and clearing up. Your quote will say how long we expect yours to take.

Do you seal gaps around fire door frames?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame and we’ll tell you if we spot problems with the door.

Can you match the sealant colour?

Normally, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.

Can you work in occupied buildings?

Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Early starts or out-of-hours work can be arranged where it’s needed.
