Fire rated sealant for Princelett homes and businesses

Honest limits

A few problems are outside what sealant work can do:

  • Issuing a fire rating or certificate for a building
  • Construction that does not provide fire resistance on its own
  • Fire doors that need new seals, closers or hardware

If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

Surfaces we seal

  • Service penetrations
  • Linear gaps

  • Plasterboard & masonry

Fire rated sealant in Princelett, done properly

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. 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. Common call-outs are for gaps filled with a product that isn’t fire-rated and open gaps behind door architraves, across door frames, linear gaps and plasterboard & masonry.

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

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Workplaces and buildings in Princelett

For seaside hotels, guest houses and holiday lets around Princelett, 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, 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.

Managing a site like Sandown Bay Academy? Then fire-stopping around service openings should be restored whenever new services go in.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Take pictures of fire stopping before ceilings or boxing go back
  • Store the list of sealed gaps with your building paperwork
  • Report cracked or damaged seals as soon as you notice them
  • Look in service cupboards and ceiling voids from time to time

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. For a village or hamlet like Princelett, the journey is planned in advance: 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. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Mention if the joints have been sealed before
  • Mention any tricky access

Advice

Princelett questions

Do you cover Princelett for fire rated sealant?

Yes, Princelett is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.

Do you work for landlords with property near Shanklin station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.

Do I have to be there?

It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.

Can you tell me which gaps need fire stopping?

No. We work from the specification you give us, and apply each product to its tested details.

Is there any odour?

Some sealants have a smell while they cure, but it fades. Opening a window helps.

Do you take on fire stopping in schools and offices?

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.

How long will you be here?

It depends on the size of the job, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We’ll tell you when we quote.

Are you insured?

Yes, we’re fully insured.

Can I do it myself?

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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What affects the cost of fire rated sealant

The price is agreed before any work begins. It’s based on:

  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows
  • Access and height

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

What to tell us for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • How we’d reach the joints
  • The type of property
  • The address or postcode of the job
  • The problem you’ve noticed

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

Different surfaces, different methods

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified, flat by flat if needed.

When to call us in Princelett

In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.

People generally contact us when they notice something like this:

  • Old fire sealant that has split or come away
  • Holes left by a change of layout
  • Seals cut through by electricians, plumbers or data installers
  • Gaps flagged on a fire risk assessment

Letting a property close to Shanklin station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
