Trusted fire rated sealant in Lower Rainham

Fire rated sealant for homes and businesses in Lower Rainham

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. If you have fire seals that have cracked with movement and linear gaps at the head of walls, we can put it right, on door frames, linear gaps and plasterboard & masonry alike.

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

Our work is backed for twelve months.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

When something else is needed

It helps to know what we cannot do too:

  • Large holes that need a different fire-stopping system
  • Fire risk assessments, which need a qualified assessor
  • A wall that is not a fire-resisting element to begin with

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

Joints and surfaces we work on

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

How it works

You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. In a small place like Lower Rainham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Mention if the joints have been sealed before
  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks

Advice

Do you need fire rated sealant in Lower Rainham?

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

Signs it’s time to call us include:

  • Door frames with gaps between frame and wall
  • Gaps where walls meet ceilings or slabs
  • Fire seals that have cracked with movement
  • Open holes round services passing through fire walls

Schools such as Thames View Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

What your quote should include

  • Which colour the sealant will be
  • How long the guarantee is
  • Whether the sealant suits the joint
  • What insurance they hold

Fire rated sealant around Lower Rainham

For seaside hotels, guest houses and holiday lets around Lower Rainham, 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. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Church of St Margaret are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. For landlords with property near Rainham (Kent) station, any gap left by new services in shared walls should be closed with a fire-rated product.

Aftercare tips

After the cure time, these simple habits help:

  • Don’t paint over fire sealant until it has cured
  • Ask every contractor to reseal any fire stopping they disturb
  • Flag any open gap you spot round a pipe or cable
  • Photograph sealed gaps before they’re covered up

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.

Why act early in Lower Rainham

Squirting in whichever sealant is nearest doesn’t make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Where a wall is exposed, as many are in small places like Lower Rainham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
