Fire rated sealant near Hamstreet

Fire rated sealant in Hamstreet

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. 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. If you’re dealing with linear gaps at the head of walls and standard silicone or caulk in a fire-stopping gap, we can help, whatever the surface.

For a small place like Hamstreet, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

All our work is covered by our one-year guarantee, wherever you are in Kent.

Your questions about fire rated sealant in Hamstreet

Can you do fire rated sealant in Hamstreet?

Yes, Hamstreet is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Do you work for landlords with property near Ham Street station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Do the sealants smell?

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

What’s the difference between intumescent and fire-rated sealant?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.

Is it OK to seal over old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

What does fire rated sealant cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Will you assess my building’s fire safety?

No. We work from the specification you give us and install to the manufacturer’s details.

Do you do fire sealant around door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door leaf and its hardware need a door specialist.

Commercial buildings in Hamstreet

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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Schools such as Hamstreet Primary Academy are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Ham Street station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Signs you need fire rated sealant in Hamstreet

Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

Signs it’s time to call us include:

  • Standard silicone or caulk in a fire-stopping gap
  • Fire seals that have cracked with movement
  • Gaps flagged on a fire risk assessment
  • Unsealed gaps around fire door frames

For buildings such as Church of the Good Shepherd, gaps around pipes and cables are worth checking after any building work there.

Choosing a sealant specialist

What affects the cost of fire rated sealant

Your quote is based on your job. We take into account:

  • Whether there’s mould to deal with
  • The old material and how stubborn it is
  • Any working-time requirements on site
  • How many rooms, windows or areas are involved

Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Asking for a quote

Photos by email are helpful but not essential. Try to tell us:

  • Photos by email, if that’s easy
  • The type of property
  • Where the job is, and your postcode
  • How we’d reach the joints

There’s no standard price list. Instead, we give you a clear price for your job. To arrange one, ring 0345 464 0079 or send us an email.

Landlord and commercial work in Hamstreet

Housing providers, facilities teams and property managers book us too in Hamstreet and across Kent. We can quote a run of properties together, and we are fully insured.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Hamstreet, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  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. We record the locations and products used for your records.

Getting ready for the visit

  • Clear the area around the work
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about parking restrictions

Ask for a quote

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, and add photos by email if you can.

Advice

What happens if it’s left?

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. Around Hamstreet, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Aftercare tips

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

  • Keep the record of products and locations with your fire safety documents
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Do not paint over fire sealant until it has cured
  • Check risers, ceiling voids and cupboards during building checks

Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
