Fire rated sealant for homes and businesses in Grazeley

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. If you are dealing with unsealed gaps where pipes and cables go through a wall and open joints along the top of partitions, we can put it right, whatever the surface.

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

The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Why act early in Grazeley

Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Where a wall is exposed, as many are in small places like Grazeley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Why book with us

  • Old sealant always removed completely
  • Fully insured
  • 20+ years of sealant experience
  • Sanitary silicone with an anti-fungal additive in wet areas

How to look after the new joints

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

  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Photograph sealed gaps before they’re covered up
  • Plan fire stopping into any work that goes through walls or floors
  • Don’t paint over fire sealant until it has cured

Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.

DIY versus a professional finish

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

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.

When to call us in Grazeley

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.

Signs it’s time to call us include:

  • Door frames with gaps between frame and wall
  • Sealant items on a fire risk assessment action list
  • New service routes left unsealed after building work
  • Gaps around pipes and cables through fire-resisting walls

Managing a site like Grazeley Parochial Church of England Aided Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

Before you book anyone

  • Which colour the sealant will be
  • What preparation is included
  • Is the old sealant removed completely?
  • How much experience the applicator has

Questions from Grazeley

I let a flat near Reading Green Park station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Is Grazeley within the area you cover?

Yes. Grazeley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.

How long does fire rated sealant take?

As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer, and we will say how long yours will take.

Can I choose the sealant colour?

In most cases you can choose. We will tell you which colours the right product comes in.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.

Can I do it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Is there any odour?

Possibly a little. Any smell clears as the sealant cures.

For landlords and businesses

Letting agents and landlords in Grazeley can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

If you manage several properties in or around Grazeley, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

What happens on the day

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Grazeley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any water getting in
  • Mention any parking rules near the property
