DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. 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.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Fire rated sealant in Upperton

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. Typical jobs include open joints along the top of partitions and fire seals that have cracked with movement, across pipe & cable gaps, linear gaps and service penetrations.

Work in a small place like Upperton is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

All our work is covered by a one-year guarantee.

Commercial buildings in Upperton

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

In and around Upperton, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Common questions in Upperton

Is Upperton within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is there a guarantee on fire rated sealant in Upperton?

Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can I add another job to the visit?

Yes, we can. Several rooms, windows or areas can go on one quote.

Where are you based?

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

I rent my home. Can I book you?

Yes. Check with your landlord; we can send the quote to them too.

Honest limits

Before you book, it’s worth knowing the limits too:

  • A wall that isn’t a fire-resisting element to begin with
  • Fire doors that need new seals, closers or hardware
  • Large holes that need a different fire-stopping system

If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.

Surfaces we seal

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

How it works

When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Upperton, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Where the tested detail needs backing or fill, we fit it.
  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.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks

How to get a quote

Advice

Quotes for fire rated sealant in Upperton

Some jobs are bigger than they look, and some smaller. The main factors:

  • The size of the job
  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • Whether there’s mould to deal with

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Asking for a quote

What to tell us when you ask for a quote:

  • If someone has resealed it before
  • Whether it’s a home or a business
  • What’s wrong with the joints now
  • The rough size of the job

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Do you need fire rated sealant in Upperton?

A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.

Most people get in touch when they notice one of these:

  • Damaged fire sealant left by other trades
  • Joints picked up in a fire-stopping survey
  • Gaps left after a refit or conversion
  • Open joints along the top of partitions

For buildings such as The Parish Church of All Hallows, gaps around pipes and cables are worth checking after any building work there.

What to look for in a quote

  • What guarantee comes with the work
  • Is the old sealant removed completely?
  • Whether the sealant suits the joint
  • How the colour is chosen

What the job involves on each surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before applying the sealant.

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
