Fire rated sealant in Waterham

Fire rated sealant in Waterham

Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you have gaps flagged on a fire risk assessment and standard silicone or caulk in a fire-stopping gap, we can help.

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

There’s a 12-month guarantee on every job, large or small.

Workplaces and buildings in Waterham

If you run a hotel, guest house or holiday let in a coastal place like Waterham, 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. 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.

For site and facilities teams at buildings such as Hernhill Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

Waterham is about 3 miles south-west of Whitstable, in Kent. Every kind of property in Waterham is covered for fire rated sealant, old or new, large or small. The work is guaranteed for a year. Waterham is one of 922 places in Kent we cover for fire rated sealant. Chelmsford is on our list too, about 35 miles from Waterham.

For landlords and businesses

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What affects the cost of fire rated sealant

Call for a quick quote. What matters most is:

  • How much old sealant there is and how hard it is to remove
  • How many rooms, windows or areas are involved
  • Any working-time requirements on site
  • Access and height

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Helping us quote

When you call or email, these details help:

  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it has been sealed before
  • A few photos by email, if you can

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

The process

You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. For a village or hamlet like Waterham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  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. 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

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any leaks or damp you’ve noticed
  • Keep pets and children clear of the area while we work

Related advice

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

When it is not the sealant

To be straight with you, there are a few things sealant will not fix:

  • Large holes that need a different fire-stopping system
  • Assessing a building’s fire safety
  • Sign-off of the building, which sits with building control or your assessor

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

Joints and surfaces we work on

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

When to call us in Waterham

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried.

It’s worth asking for a quote if you see:

  • Joints picked up in a fire-stopping survey
  • Open holes round services passing through fire walls
  • Open joints along the top of partitions
  • Fire seals that have cracked with movement

Letting a property close to Whitstable station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What your quote should include

  • What happens if they find a problem under the old sealant
  • Whether they seal over old material or remove it
  • How long to leave it before use
  • Which sealant they’ll use, and why

Your questions about fire rated sealant in Waterham

Do you cover smaller places like Waterham?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

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

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.

How much does fire rated sealant cost in Waterham?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Can you quote for more than one area?

Of course. Doing several areas at once is generally more efficient.

Do you work in flats, HMOs and commercial buildings?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.

Do you remove the old sealant?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Where are you based?

Mr Mastic is based in Crawley. We cover Waterham and the rest of Kent, along with the rest of our area.

What the job involves on each surface

Door frames

Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details before the trim goes back.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first.
