Fire rated sealant for Mottisfont homes and businesses

How it works

You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. For a village or hamlet like Mottisfont, 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.

How to prepare

  • On commercial sites, let us know about site rules
  • Mention any tricky access
  • Keep children and pets away from the work area

Fire rated sealant in Mottisfont, done properly

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Typical jobs include joints picked up in a fire-stopping survey and door frames with gaps between frame and wall, across service penetrations, plasterboard & masonry and door frames.

For a small place like Mottisfont, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of fire rated sealant

The quote reflects the job in front of us. We take into account:

  • The size of the job
  • How many rooms, windows or areas are involved
  • Whether there’s mould to deal with
  • The old material and how stubborn it is

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

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • What’s wrong with the joints now
  • If someone has resealed it before
  • The type of property
  • The rough size of the job

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.

Why it’s worth doing now in Mottisfont

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like Mottisfont, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

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.

  • Anti-fungal sanitary silicone in wet areas

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

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.

Do you need fire rated sealant in Mottisfont?

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

Any of these means the joints need attention:

  • Gaps filled with a product that is not fire-rated
  • New service routes left unsealed after building work
  • Open gaps behind door architraves
  • Linear gaps at the head of walls

If you look after a church, hall or community building such as Church of St Andrew, service openings in its walls need the right fire-rated sealant, as in any building.

Our hiring checklist

Your questions about fire rated sealant in Mottisfont

Will you come out to Mottisfont?

Yes, Mottisfont is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is Mottisfont in your area for fire rated sealant?

Yes. We work across London and the South East, and Mottisfont is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.

Can new sealant go over the old?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.

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. Bigger jobs take longer, and we’ll say how long yours will take.

Can you do several jobs on one visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Where do you work from?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.

For landlords and businesses

We also work for property managers and facilities teams in Mottisfont and across Hampshire. We can quote a run of properties together, and we are fully insured for the work.

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.

Commercial buildings in Mottisfont

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.

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Deciding what fire stopping a building needs
  • Certifying a building or signing off its fire safety
  • Problems with the door itself rather than the gap around the frame

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