How we handle fire rated sealant in Weston

Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on, one gap at a time. If you have linear gaps at the head of walls and gaps left after a refit or conversion, we can put it right, on linear gaps, door frames and service penetrations alike.

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

All our work comes with our 12-month guarantee, wherever you are in West Berkshire.

What affects the cost of fire rated sealant

We quote each job individually. These are the things that affect it:

  • Any mould that needs treating
  • Access and height
  • Any working-time requirements on site
  • The number and length of the joints

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we’ll talk you through it.

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • Whether it’s a home or a business
  • Whether it has been sealed before
  • Roughly how big the job is
  • The address or postcode of the job

Need a quote? Please call 0345 464 0079 or drop us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.

DIY versus a professional finish

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

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What we do, step by step

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Weston, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

How to prepare

  • Let us know about parking restrictions
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any sign-in or site rules at work premises

Do you work in flats, HMOs and commercial buildings?

Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Early starts or out-of-hours work can be arranged if that suits the building.

What do you need from me for a quote?

A short description and the location, with photos by email if possible. We will ask anything else we need to know.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. We use whichever the specification and tested details call for.

Can I do it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Different surfaces, different methods

Flats and HMOs

Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.

Linear gaps

A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.

Do you need fire rated sealant in Weston?

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

It’s worth asking for a quote if you see:

  • New service routes left unsealed after building work
  • Old fire sealant that has split or come away
  • Door frames with gaps between frame and wall
  • Gaps around pipes and cables through fire-resisting walls

Community buildings like St Thomas' Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Before booking anyone

  • Which sealant they’ll use, and why
  • What preparation is included
  • Who does the work, and how experienced they are
  • Is the old sealant removed completely?

Aftercare tips

Simple care keeps the joints in good condition. Our advice:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Tell trades working in the building that fire seals must be put back
  • Flag any open gap you spot round a pipe or cable
  • Include fire stopping when you schedule refits

Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.

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.
