Fire rated sealant for homes and businesses in Merstone

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you’re dealing with seals cut through by electricians, plumbers or data installers and old fire sealant that has split or come away, we can help, whatever the surface.

In a village or hamlet like Merstone, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

What fire rated sealant looks like in Merstone

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’re given, installing the product to its tested details.

Around Merstone, as everywhere, fire rated sealant is only as good as the preparation behind it. For landlords with property near Shanklin station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How we quote for fire rated sealant

For a quick quote, just ask. The main things that affect it are:

  • Whether the work is at height
  • Any mould that needs treating
  • The old material and how stubborn it is
  • Which sealant suits the joint

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What we need to know

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Pictures of the joints, sent by email
  • The address or postcode of the job
  • The problem you’ve noticed
  • How we’d reach the joints

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved.

Honest limits

In fairness, some problems need a different trade:

  • Issuing a fire rating or certificate for a building
  • Openings too large for sealant, which need batts, boards or another system
  • A wall that is not a fire-resisting element to begin with

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

Where we work in Merstone

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

Surface by surface

Plasterboard walls

We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail.

DIY versus a professional finish

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.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

How it works

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Merstone 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. Old or unsuitable sealant is cut out and the gap cleaned.
  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. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Clear the area around the work
  • Mention if the joints have been sealed before
  • Mention any leaks or damp you’ve noticed

Advice

Leave it or put it right?

Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again once someone inspects it. In a small place like Merstone, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear price for the lot.

How much does fire rated sealant cost in Merstone?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

How long will you be here?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll say how long yours will take.

Will the old sealant be removed?

Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

Will you assess my building’s fire safety?

No, we don’t assess buildings. When your assessor or designer has set out what’s needed, we’ll quote for the sealant work on it.
