When to call us in Nash Street

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.

Common reasons people contact us are:

  • Gaps around pipes and cables through fire-resisting walls
  • Seals cut through by electricians, plumbers or data installers
  • Cracked or shrunken fire-rated sealant
  • Holes left by a change of layout

For site and facilities teams at buildings such as Chiddingly Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Choosing a sealant specialist

Fire rated sealant in Nash Street, 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. We work on service penetrations, door frames and plasterboard & masonry, and people most often call us about linear gaps at the head of walls and fire stopping disturbed by later work.

Somewhere as small as Nash Street, 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.

DIY versus a professional finish

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: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Commercial buildings in Nash Street

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

Community buildings like The Parish Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Rented homes near Berwick (Sussex) station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Common questions in Nash Street

Is Nash Street within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you do fire rated sealant in Nash Street?

Yes, Nash Street is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Where are you based?

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

Is the work guaranteed?

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

Is there any odour?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

What does fire rated sealant cost?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.

Aftercare tips

Looking after new joints is easy:

  • Photograph sealed gaps before they’re covered up
  • Store the list of sealed gaps with your building paperwork
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Ask which product was used before you paint

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot and we’ll tell you which one you have.

An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.

Why it’s worth doing now in Nash Street

Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing once someone inspects it. In a small place like Nash Street, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Why choose Mr Mastic in Nash Street

  • Quality sealants from Arbo and Everbuild
  • One-year guarantee on every job

How the visit works

We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere like Nash Street needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Tell us if parking is tricky
  • For business premises, tell us about site rules or sign-in
  • Move anything stored near the joints
