How we handle fire rated sealant in Dinton

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. We’re often asked to deal with old fire sealant that has split or come away and gaps left after a refit or conversion, on linear gaps, service penetrations and flats & HMOs.

For a small place like Dinton, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Why deal with it now?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. In a small place like Dinton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Surface by surface

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.

Linear gaps

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

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • Photograph sealed gaps before they’re covered up
  • Ask every contractor to reseal any fire stopping they disturb
  • Get damaged fire seals looked at promptly
  • Keep the record of products and locations with your fire safety documents

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.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Dinton: your questions answered

Is Dinton within the area you cover?

Yes. Dinton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is Dinton in your area for fire rated sealant?

Yes. We work across London and the South East, and Dinton is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.

What should I tell you?

A short description and the location, plus pictures if you have them. If we need more, we’ll ask.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Will it make a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Can new sealant go over the old?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Do you provide details of the products used?

Yes. We record the locations we’ve sealed and the products used.

Will there be a smell?

Some sealants have a smell while they cure. Ventilation helps.

Quotes for fire rated sealant in Dinton

For a quick quote, just ask. The main things that affect it are:

  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • The size of the job
  • Mould in or behind the old joints

The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What we need to know

You don’t need to know the technical terms. Just tell us:

  • How many joints, rooms or windows are involved
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel
  • Any previous sealing or DIY work

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, ring 0345 464 0079 or email us.

Should I try it myself first?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

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.

What we do, step by step

When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before we start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Dinton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children

How to get a quote
