Fire rated sealant for Up Somborne homes and businesses

Different surfaces, different methods

Flats and HMOs

Conversions normally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.

About our fire rated sealant in Up Somborne

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you have open gaps behind door architraves and gaps where walls meet ceilings or slabs, we can put it right, on door frames, service penetrations and plasterboard & masonry alike.

In a village or hamlet like Up Somborne, 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.

Each job carries a 12-month guarantee, whatever its size.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Signs you need fire rated sealant in Up Somborne

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

Look out for these signs:

  • Cracked or shrunken fire-rated sealant
  • Standard silicone or caulk in a fire-stopping gap
  • Unsealed gaps around fire door frames
  • Seals cut through by electricians, plumbers or data installers

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

Choosing a sealant specialist

How it works

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Up Somborne needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Clear items away from the joints we are working on
  • Tell us if parking is tricky
  • Tell us about any previous sealing or DIY attempts

Advice

Why deal with it now?

Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again when the building is next checked. Around Up Somborne, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What you get with us

  • Old sealant always removed completely
  • An ARBOMaster approved applicator
  • Anti-fungal silicone where joints get wet
  • Trusted Arbo and Everbuild sealants

When something else is needed

We will not take on work that will not last, so these are the limits:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire doors that need new seals, closers or hardware
  • Construction that does not provide fire resistance on its own

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Up Somborne: your questions answered

Will you come out to Up Somborne?

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

Is fire rated sealant in Up Somborne guaranteed?

All our work, in Up Somborne and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.

Do you seal gaps around fire door frames?

Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.

Can new sealant go over the old?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

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 follow the requirements from your assessor, designer or building control.

Are you fully insured?

Yes. We’re fully insured for every job we do.

Can tenants book the work?

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

What fire rated sealant looks like in Up Somborne

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

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

How we quote for fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • The old material and how stubborn it is
  • When we can work, for business premises
  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints

Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

  • Photos by email, if that is easy

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