About our fire rated sealant in Lyminster

Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We work on door frames, pipe & cable gaps and service penetrations, and common reasons people get in touch are linear gaps at the head of walls and unsealed gaps where pipes and cables go through a wall.

Somewhere as small as Lyminster, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

There’s a 12-month guarantee on every job, whatever its size.

What affects the cost of fire rated sealant

You will get a clear quote before work begins. It takes into account:

  • Whether the work is at height
  • The number of rooms or windows
  • The size of the job
  • Whether old sealant or filler has to be cut out

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Helping us quote

When you contact us, these details help:

  • If it’s domestic, commercial or a hotel
  • The address or postcode of the job
  • Photos by email, if that’s easy
  • The rough size of the job

Common questions in Lyminster

I let a flat near Arundel station. Can you help?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Do you cover smaller places like Lyminster?

Yes, Lyminster is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can I use normal mastic around a pipe through a fire wall?

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

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Where is Mr Mastic based?

Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Is there a guarantee?

Yes. Every job comes with a 12-month guarantee.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. The specification and the tested detail decide which is used.

Landlords, agents and businesses in Lyminster

We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.

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.

Why act early in Lyminster

For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. Older cottages and farmhouses around Lyminster can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Why book with us

  • An ARBOMaster approved applicator
  • Every job guaranteed for a year
  • Quality sealants from Arbo and Everbuild
  • Anti-fungal silicone where joints get wet

Can I do it myself?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How the visit works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access, and the area is left clean. In a small place like Lyminster, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  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.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about earlier repairs to the joints

Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.

What fire rated sealant looks like in Lyminster

For seaside hotels, guest houses and holiday lets around Lyminster, 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. There are hotels and other places to stay in and around Lyminster. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

For site and facilities teams at buildings such as Lyminster Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like The Parish Church of St Mary Magdalen are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Letting a property close to Arundel station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What the job involves on each surface

Door frames

We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.

Flats and HMOs

Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

What we cannot put right

We won’t take on work that won’t last, so these are the limits:

  • Walls or floors that weren’t built to resist fire
  • Sign-off of the building, which sits with building control or your assessor
  • Fire doors that need new seals, closers or hardware

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
