Fire rated sealant in Bassett Green

How we quote for fire rated sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Whether old sealant or filler has to be cut out
  • Access and height
  • Which sealant suits the joint
  • Whether there’s mould to deal with

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Asking for a quote

To help us quote quickly, please include:

  • Any access issues, like height or stairs
  • How many joints, rooms or windows are involved
  • What the problem is, such as mould, gaps, leaks or cracking
  • A few pictures by email, if you can

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or drop us an email.

Fire rated sealant in Bassett Green, done properly

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on service penetrations, pipe & cable gaps and linear gaps, and people most often call us about gaps around pipes and cables through fire-resisting walls and door frames with gaps between frame and wall.

Around a place like Bassett Green, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.

We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

How it works

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. A visit to Bassett Green is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  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. 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.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Mention if the joints have been sealed before
  • For business premises, tell us about site rules or sign-in

Advice

Why deal with it now?

For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we will tell you. Homes in smaller places like Bassett Green can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

How to look after the new joints

Aftercare is simple, and it makes a real difference:

  • Ask which product was used before you paint
  • Never patch a fire seal with standard sealant
  • Check risers, ceiling voids and cupboards during building checks
  • Tell trades working in the building that fire seals must be put back

Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Deciding what fire stopping a building needs
  • Construction that doesn’t provide fire resistance on its own
  • Openings too large for sealant, which need batts, boards or another system

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

Joints and surfaces we work on

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

What the job involves on each surface

Linear gaps

A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement.

Plasterboard walls

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

FAQs for Bassett Green

Will you come out to Bassett Green?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you work in hotels near Bassett Green?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

Do you guarantee your work?

Yes. Every job comes with our 12-month guarantee.

Do I need to be at home?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Is there any odour?

Possibly a little. It fades as the sealant cures, and ventilation helps.

Which products do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.

Are you insured?

Yes. We’re fully insured for domestic and commercial work.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.

Commercial buildings in Bassett Green

If you run a hotel, guest house or holiday let in a coastal place like Bassett Green, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

If you let a flat or house near Swaythling station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Bassett Green Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as St Alban's Church, gaps around pipes and cables are worth checking after any building work there.
