Fire rated sealant in Wallingford

How we handle fire rated sealant in Wallingford

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. Common call-outs are for linear gaps at the head of walls and gaps flagged on a fire risk assessment, on door frames, pipe & cable gaps and linear gaps.

For a pub, café, guest house or shop in or near Wallingford, the washrooms and kitchen need the same attention as a big site.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Landlords and letting agents in Wallingford can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

Leave it or put it right?

Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. In an older home around Wallingford, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.

Why book with us

  • A 12-month guarantee on all work
  • Over 20 years’ experience
  • We’re fully insured
  • Approved under the ARBOMaster scheme

What sealant work cannot fix

New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire risk assessments, which need a qualified assessor
  • Doors that aren’t fire doors in the first place

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

Joints and surfaces we work on

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

What affects the quote in Wallingford

The price is agreed before any work begins. It’s based on:

  • How many rooms, windows or areas are involved
  • How easy the joints are to reach
  • The old material and how stubborn it is
  • Working hours on commercial sites

The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Asking for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the job is, and your postcode
  • Pictures of the joints, sent by email
  • Roughly how big the job is

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, call 0345 464 0079 or drop us an email.

Should I try it myself first?

If you’re 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 does not work out, we can still put it right.

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.

What happens on the day

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on how many gaps there are, depending on the size of the job. In a smaller place like Wallingford, 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. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  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 stairs, lifts or work at height
  • Mention if the joints have been sealed before
  • Tell us about any water getting in

Fire rated sealant around Wallingford

If you look after a building such as Fir Tree Junior School, service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Cholsey station, any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like St Mary-le-More are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • Ask every contractor to reseal any fire stopping they disturb
  • Look in service cupboards and ceiling voids from time to time
  • Check whether a sealant can be painted before decorating over it
  • Plan fire stopping into any work that goes through walls or floors

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
