Need fire rated sealant in Hardley?

Should I try it myself first?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Fire rated sealant in Hardley, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. We are often asked to deal with cracked or shrunken fire-rated sealant and gaps flagged on a fire risk assessment, across plasterboard & masonry, pipe & cable gaps and linear gaps.

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

There’s a 12-month guarantee on every job, large or small.

Surface by surface

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

Flats and HMOs

In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before we start to keep disruption down.

Yes, Hardley is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.

What does intumescent mean?

Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

What do you need from me for a quote?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.

Will it make a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Can you work in occupied buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we will plan around it.

Do you guarantee your work?

Is standard sealant good enough for a fire gap?

No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Signs you need fire rated sealant in Hardley

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

Keep an eye out for any of the following:

  • Gaps left after a refit or conversion
  • Unsealed gaps where pipes and cables go through a wall
  • Sealant items on a fire risk assessment action list
  • Fire seals that have cracked with movement

Managing a site like The New Forest Academy? Then service openings in fire-resisting walls need checking after any refurbishment.

How the visit works

Everything for the job comes with us, so a second trip is avoided where possible.

  2. We measure every gap and note what it’s in and what passes through.

  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Advice

Aftercare tips

A little care helps the new joints last. Our advice:

  • Never patch a fire seal with standard sealant
  • Get damaged fire seals looked at promptly
  • Take photos of fire stopping before ceilings or boxing go back
  • Store the list of sealed gaps with your building paperwork

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.

Fire rated sealant in Hardley: local notes

If you run a hotel, guest house or holiday let in a coastal place like Hardley, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 are given, installing the product to its tested details.

If you look after a church, hall or community building such as St Anne, older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Netley station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
