Trusted fire rated sealant in Priddy's Hard

Fire rated sealant in Priddy's Hard

Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on flats & HMOs, plasterboard & masonry and linear gaps, and the jobs we see most are damaged fire sealant left by other trades and sealant items on a fire risk assessment action list.

Somewhere as small as Priddy's Hard, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. In a small place like Priddy's Hard, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Aftercare tips

Looking after new joints is easy:

  • Check whether a sealant can be painted before decorating over it
  • Tell trades working in the building that fire seals must be put back
  • Flag any open gap you spot round a pipe or cable
  • Store the list of sealed gaps with your building paperwork

Do not drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

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

Do you need fire rated sealant in Priddy's Hard?

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.

Look out for these signs:

  • Gaps flagged on a fire risk assessment
  • Gaps where walls meet ceilings or slabs
  • Gaps around pipes and cables through fire-resisting walls
  • Damaged fire sealant left by other trades

For site and facilities teams at buildings such as St Vincent College, fire-stopping around service openings should be restored whenever new services go in.

Before you book anyone

  • What insurance they hold
  • Is VAT in the price?
  • How much experience the applicator has
  • Whether all the old sealant comes out first

Our hiring checklist

What we do, step by step

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are from start to finish. Somewhere as small as Priddy's Hard, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Tell us about any water getting in
  • Let us know about parking restrictions
  • Clear items away from the joints we’re working on
