Trusted fire rated sealant in Charlton-on-Otmoor

Fire rated sealant for homes and businesses in Charlton-on-Otmoor

Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you have open joints along the top of partitions and fire seals that have cracked with movement, we can put it right, whatever the surface.

In a village or hamlet like Charlton-on-Otmoor, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Our work is backed for twelve months.

Quotes for fire rated sealant in Charlton-on-Otmoor

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Mould in or behind the old joints
  • When we can work, for business premises
  • Whether the work is at height
  • The number of rooms or windows

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Helping us quote

There’s no need for technical detail. Just tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved
  • A few pictures by email, if you can

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.

Surface by 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.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Where a wall is exposed, as many are in small places like Charlton-on-Otmoor, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What you get with us

  • Neat joints and a tidy finish
  • Every job guaranteed for a year
  • Any old sealant cut out fully, not covered over
  • Over 20 years’ experience

Common problems we fix in Charlton-on-Otmoor

Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

It’s worth asking for a quote if you see:

  • Open holes round services passing through fire walls
  • Gaps flagged on a fire risk assessment
  • Gaps where walls meet ceilings or slabs
  • Damaged fire sealant left by other trades

For landlords with property near Islip station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

FAQs for Charlton-on-Otmoor

Can you do fire rated sealant in Charlton-on-Otmoor?

Yes, Charlton-on-Otmoor is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.

Can you help a landlord with a rental near Islip station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.

Is the work guaranteed?

Yes, always. There’s a 12-month guarantee on every job.

How long will you be here?

Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer, and we will tell you how long to expect.

Do I need to be at home?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Do you certify the fire stopping?

Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Is intumescent sealant the same as fire-rated sealant?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

For landlords and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

DIY sealant or a professional job?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Workplaces and buildings in Charlton-on-Otmoor

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

Community buildings like Church of St Mary the Virgin are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Charlton-on-Otmoor Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

The process

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. For a village or hamlet like Charlton-on-Otmoor, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided 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.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
