Fire rated sealant in Didling

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you’re dealing with new service routes left unsealed after building work and door frames with gaps between frame and wall, we can put it right, whatever the surface.

Work in a small place like Didling is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

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.

Signs you need fire rated sealant in Didling

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.

Keep an eye out for these signs:

  • Unsealed gaps where pipes and cables go through a wall
  • Gaps flagged on a fire risk assessment
  • Gaps filled with a product that is not fire-rated
  • Door frames with gaps between frame and wall

If you look after a church, hall or community building such as Church of St Andrew, gaps around pipes and cables are worth checking after any building work there.

Questions to ask before you book

  • Whether they seal over old material or remove it
  • How the surfaces are prepared before sealing
  • How hidden problems are handled
  • How long the guarantee is

Choosing a sealant specialist

What affects the quote in Didling

Every job gets its own quote. These are the things that affect it:

  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove
  • The number and length of the joints
  • Working hours on commercial sites

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

What we need to know

To help us quote quickly, please include:

  • Where the job is, and your postcode
  • Any previous sealing or DIY work
  • The rough size of the job
  • A few pictures by email, if you can

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Surface by surface

Door frames

We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we will say if we spot a problem with them.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.

Commercial buildings in Didling

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Around Didling, as everywhere, fire rated sealant is only as good as the preparation behind it.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Photograph sealed gaps before they’re covered up
  • Check risers, ceiling voids and cupboards during building checks
  • Get damaged fire seals looked at promptly
  • Allow for resealing whenever new services are run

Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.

Why it’s worth doing now in Didling

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In a small place like Didling, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Didling needs a little journey planning: 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 start with the survey or action list, checking the size and surfaces of every gap.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  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. We record the locations and products used for your records.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Let us know about stairs, lifts or work at height
  • Where the joints are inside, avoid wetting them before we arrive
