When something else is needed

It helps to know what we can’t do:

  • Construction that doesn’t provide fire resistance on its own
  • Fire risk assessments, which need a qualified assessor
  • Certifying a building or signing off its fire safety

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Joints and surfaces we work on

  • Service penetrations
  • Flats & HMOs
  • Linear gaps

  • Plasterboard & masonry
  • Door frames

How we handle fire rated sealant in Langrish

Deciding which gaps need fire stopping isn’t 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 plasterboard & masonry, linear gaps and service penetrations, and common reasons people get in touch are holes left by a change of layout and joints picked up in a fire-stopping survey.

If you have holiday lets, a converted barn used for business or a community building near Langrish, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

All our work is covered by a 12-month guarantee, wherever you are in Hampshire.

Fire rated sealant around Langrish

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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

Community buildings like Church of St John the Evangelist are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Letting a property close to Petersfield station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What we’re called out for in Langrish

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

Signs it’s time to call us include:

  • Unsealed gaps where pipes and cables go through a wall
  • Fire seals that have cracked with movement
  • Door frames with gaps between frame and wall
  • Sealant items on a fire risk assessment action list

Schools such as Langrish Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

Before you book anyone

  • What insurance they hold
  • How long the guarantee is
  • How the colour is chosen
  • Whether all the old sealant comes out first

How to choose a mastic man

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Include fire stopping when you schedule refits
  • Flag any open gap you spot round a pipe or cable
  • Do not paint over fire sealant until it has cured
  • Tell trades working in the building that fire seals must be put back

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 have them put right.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so you can show it was dealt with.

Why it’s worth doing now in Langrish

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. We will say so if a gap needs something other than sealant. Around Langrish, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Will we have a record of what was sealed?

Yes. We record the locations we have sealed and the products used for your files.

Can you tell me which gaps need fire stopping?

No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few photos.

What we do, step by step

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Langrish 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. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • For business premises, tell us about site rules or sign-in
  • Mention any parking rules near the property

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

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 fails, we can still redo it.
