Trusted fire rated sealant in Wellhouse

The process

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Wellhouse, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  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.

Before we arrive

  • Let us know about parking restrictions
  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before

Fire rated sealant in Wellhouse, done properly

We often work from an action list drawn up by a fire risk assessor on buildings across Wellhouse. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. If you have gaps filled with a product that isn’t fire-rated and door frames with gaps between frame and wall, we can put it right, on linear gaps, flats & HMOs and service penetrations alike.

If you have holiday lets, a converted barn used for business or a community building near Wellhouse, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

All of our work is guaranteed for twelve months.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Keep photos of seals that will be hidden
  • Keep the record of products and locations with your fire safety documents
  • Get damaged fire seals looked at promptly
  • Never patch a fire seal with standard sealant

Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

Common problems we fix in Wellhouse

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

If you can see any of these, it’s time to have the joints looked at:

  • Open holes round services passing through fire walls
  • Fire seals that have cracked with movement
  • Unsealed gaps around fire door frames
  • Seals cut through by electricians, plumbers or data installers

For site and facilities teams at buildings such as Hermitage Primary School, service openings in fire-resisting walls need checking after any refurbishment.

What to look for in a quote

  • How much experience the applicator has
  • How the colour is chosen
  • Is VAT in the price?
  • When the joint can take water or movement

Choosing a sealant specialist

Fire rated sealant around Wellhouse

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 work to the specification you are given, installing the product to its tested details.

For buildings such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking. For landlords with property near Thatcham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Can I do it myself?

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.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Different surfaces, different methods

Flats and HMOs

Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance to keep disruption down.

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.

When something else is needed

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Construction that doesn’t provide fire resistance on its own
  • Big openings where sealant alone is not the tested solution
  • Deciding what fire stopping a building needs

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.

Surfaces we seal

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

Wellhouse: your questions answered

Is Wellhouse within the area you cover?

Yes, Wellhouse 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.

Do you work for landlords with property near Thatcham station?

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

How long does the job take?

It depends on the size of the job, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We’ll tell you when we quote.

Do you hold any approvals?

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

Will we have a record of what was sealed?

Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

Is intumescent sealant the same as fire-rated sealant?

Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Leave it or put it right?

Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like Wellhouse, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
