Fire rated sealant in Cowfold

How the visit works

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Cowfold, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for 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.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Move anything stored near the joints
  • Mention any sign-in or site rules at work premises

Advice

Fire rated sealant in Cowfold, done properly

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We are often asked to deal with joints picked up in a fire-stopping survey and old fire sealant that has split or come away, on plasterboard & masonry, door frames and flats & HMOs.

For holiday lets, converted business premises or a community building near Cowfold, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Common problems we fix in Cowfold

Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.

The most common problems we see are:

  • Open gaps behind door architraves
  • Gaps where walls meet ceilings or slabs
  • Holes left by a change of layout
  • Old fire sealant that has split or come away

For site and facilities teams at buildings such as St Peter's CofE (Aided) Primary School, fire-stopping around service openings should be restored whenever new services go in.

Fire rated sealant in Cowfold: local notes

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, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

If you look after a church, hall or community building such as Church of St Peter, older buildings that have had new heating or wiring often have service gaps worth checking.

Common questions in Cowfold

What guarantee comes with fire rated sealant in Cowfold?

Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Will you come out to Cowfold?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Are you an approved applicator?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Can new sealant go over the old?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame.

What information do you need?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.

Do you carry out fire risk assessments?

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

What does intumescent mean?

An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

When something else is needed

We won’t take on work that will not last, so here’s what sealant cannot put right:

  • Problems with the door itself rather than the gap around the frame
  • Openings too large for sealant, which need batts, boards or another system
  • Issuing a fire rating or certificate for a building

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

What we seal

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

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How we quote for fire rated sealant

Call for a quick quote. The main things that affect it are:

  • The size of the job
  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out
  • When we can work, for business premises

Every job is a little different, 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.

What to tell us for a quote

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

  • What the problem is, such as mould, gaps, leaks or cracking
  • The type of property
  • How we’d reach the joints
  • Whether it has been sealed before

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or drop us an email.

How the job changes by surface

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.

Masonry and concrete

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

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

Landlords and agents in Cowfold can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
