About our fire rated sealant in Wallington

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. If you have cracked or shrunken fire-rated sealant and ordinary sealant used where a fire-rated product was needed, we can help.

If you run a pub, café, guest house or shop in or near Wallington, its washrooms and kitchen need the same sealant care as any big building.

Whatever the size of the job, it’s backed by our 12-month guarantee in Wallington and across Hampshire.

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Make resealing part of every contractor’s brief
  • Ask which product was used before you paint
  • Take pictures of fire stopping before ceilings or boxing go back
  • Include fire stopping when you schedule refits

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.

How the job changes by surface

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we’ll tell you.

How it works

You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on how many gaps there are for a typical job. For a job in Wallington, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Access to each area is agreed so the work can run in order.
  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Keep pets and children clear of the area while we work
  • Tell us about access, such as stairs, a lift or high-level joints

Signs you need fire rated sealant in Wallington

A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Look out for any of the following:

  • Ordinary sealant used where a fire-rated product was needed
  • Open joints along the top of partitions
  • Seals cut through by electricians, plumbers or data installers
  • Gaps flagged on a fire risk assessment

Schools such as Wykeham House School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Choosing a sealant specialist

Should I try it myself first?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Your questions about fire rated sealant in Wallington

Do you cover Wallington for fire rated sealant?

Yes. We work across London and the South East, and Wallington is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. 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.

What fire rating will the seal have?

That isn’t something we state or certify. Your specification sets the requirement, and we apply a product tested for it.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

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 will give you a better idea when we quote.

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.

Commercial buildings in Wallington

If you run a hotel, guest house or holiday let in a coastal place like Wallington, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

Community buildings like Parish Church of St Peter and St Paul are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Fareham station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Landlords, agents and businesses in Wallington

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

What we can’t put right

New sealant can’t fix everything, and we will tell you before any work starts. It won’t solve:

  • Sign-off of the building, which sits with building control or your assessor
  • A wall that isn’t a fire-resisting element to begin with
  • Doors that aren’t fire doors in the first place

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
