Fire rated sealant in Horsemere Green

Fire rated sealant in Horsemere Green

Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, one gap at a time. We work on service penetrations, plasterboard & masonry and door frames, and common reasons people get in touch are unsealed gaps around fire door frames and linear gaps at the head of walls.

In a village or hamlet like Horsemere Green, 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.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Common questions in Horsemere Green

Can you do fire rated sealant in Horsemere Green?

Yes, Horsemere Green is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.

Can you help a landlord with a rental near Ford station?

Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.

Can I choose the sealant colour?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

Where do you work from?

We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Can new sealant go over the old?

No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can ordinary silicone be used in a fire-stopping gap?

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

The process

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like Horsemere Green, the journey is planned in advance: 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. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  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.

Preparing for the visit

  • Clear the area around the work
  • Mention any parking rules near the property
  • Let us know about stairs, lifts or work at height

Advice

Landlord and commercial work in Horsemere Green

Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

What affects the cost of fire rated sealant

There’s no set price list. What we look at:

  • The number and length of the joints
  • Mould in or behind the old joints
  • Any working-time requirements on site
  • Access and height

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What to tell us for a quote

What to tell us when you ask for a quote:

  • How many joints, rooms or windows are involved
  • If someone has resealed it before
  • Photos by email, if that’s easy
  • Where the job is, and your postcode

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

How the job changes by surface

Door frames

We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product.

Leave it or put it right?

A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Older cottages and farmhouses around Horsemere Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit generally makes better use of the time than several visits. We will give you a clear quote for the lot.

Why us?

  • Anti-fungal sanitary silicone in wet areas
  • 20+ years of sealant experience
  • Experience in homes, commercial sites and hotels
  • Tidy, careful work

Commercial buildings in Horsemere Green

For seaside hotels, guest houses and holiday lets around Horsemere Green, 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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

For buildings such as The Parish Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as St Mary's CofE Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
