Fire rated sealant in Holbrook, done properly

Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on pipe & cable gaps, flats & HMOs and plasterboard & masonry, and the jobs we see most are ordinary sealant used where a fire-rated product was needed and gaps around pipes and cables through fire-resisting walls.

Somewhere as small as Holbrook, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

What happens if it’s left?

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Holbrook, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Why choose Mr Mastic in Holbrook

  • Anti-fungal sanitary silicone in wet areas
  • Fully insured
  • Over 20 years’ experience

Fire rated sealant around Holbrook

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a church, hall or community building such as St. Mark's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Warnham station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Holbrook is about 2 miles north of Horsham, in West Sussex. We carry out fire rated sealant for householders, landlords and businesses in Holbrook and nearby, as part of our work across West Sussex. We cover 371 towns and villages across West Sussex, large and small.

How the visit works

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are from start to finish. In a small place like Holbrook, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

Preparing for the visit

  • Tell us if parking is tricky
  • Clear the area around the work
  • Try not to wet indoor joints just before the visit

What we are called out for in Holbrook

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

Look out for any of the following:

  • Gaps filled with a product that isn’t fire-rated
  • Seals cut through by electricians, plumbers or data installers
  • Fire seals that have cracked with movement
  • Linear gaps at the head of walls

Schools such as Holbrook Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

What your quote should include

  • When the joint can take water or movement
  • The length of the guarantee
  • Which sealant they’ll use, and why
  • What insurance they hold

What sealant work can’t fix

Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant will not put right:

  • Assessing a building’s fire safety
  • Sign-off of the building, which sits with building control or your assessor
  • Walls or floors that weren’t built to resist fire

Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.

Joints and surfaces we work on

  • Flats & HMOs
  • Pipe & cable gaps
  • Plasterboard & masonry
  • Door frames
  • Linear gaps
  • Service penetrations

Questions from Holbrook

Do you cover Holbrook for fire rated sealant?

Yes, Holbrook is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.

Is Holbrook within the area you cover?

Yes, Holbrook 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.

Will you assess my building’s fire safety?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

Are you insured?

Yes. Full insurance covers our work.

What does fire rated sealant cost?

We do not 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 we start.

Can you match the sealant colour?

Yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.

Is intumescent sealant the same as fire-rated sealant?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. We use whichever the specification and tested details call for.

Is the work guaranteed?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Ask every contractor to reseal any fire stopping they disturb
  • Photograph sealed gaps before they’re covered up
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Store the list of sealed gaps with your building paperwork

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
