Fire rated sealant near Westhumble

What happens if it’s left?

Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again when the building is next checked. In a small place like Westhumble, 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 will explain what it covers.

Why Westhumble clients choose us

  • We leave the area clean and tidy
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Old sealant always removed completely
  • We’re fully insured

About our fire rated sealant in Westhumble

We can work through a building room by room or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. If you are dealing with door frames with gaps between frame and wall and open joints along the top of partitions, we can put it right.

In a village or hamlet like Westhumble, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

You get a one-year guarantee, the same in Westhumble as everywhere else we work.

How the job changes by surface

Linear gaps

Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both.

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and record where they are.

What fire rated sealant looks like in Westhumble

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Westhumble has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

For site and facilities teams at buildings such as The Ashcombe School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Michael, service openings in its walls need the right fire-rated sealant, as in any building.

How we quote for fire rated sealant

Jobs vary more than people expect. What affects the quote:

  • How easy the joints are to reach
  • The number of rooms or windows
  • The old material and how stubborn it is
  • Whether there’s mould to deal with

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Asking for a quote

To make quoting easier, let us know:

  • Whether it has been sealed before
  • Whether it’s a home or a business
  • Where the property is
  • Photos by email, if that is easy

For fire rated sealant in Westhumble, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out 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.

Landlords, agents and businesses in Westhumble

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Westhumble questions

Do you work in hotels near Westhumble?

Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Is Westhumble within the area you cover?

Yes, Westhumble is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

How long does the job take?

As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll tell you how long to expect.

Do you have insurance?

Yes. We’re fully insured, and we can confirm the details when we quote.

Can I add another job to the visit?

Of course. Doing several areas at once is generally more efficient.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

Can you tell me how many minutes the seal will last?

We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.

Can I choose the sealant colour?

Yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.

What we do, step by step

On the day, we start by going over the job with you, 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 like Westhumble needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. 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.

Getting ready for the visit

  • Mention any tricky access
  • Keep children and pets away from the work area
  • Mention any sign-in or site rules at work premises

When to call us in Westhumble

Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

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

  • Gaps where walls meet ceilings or slabs
  • Gaps flagged on a fire risk assessment
  • Ordinary sealant used where a fire-rated product was needed
  • Damaged fire sealant left by other trades

For landlords with property near Box Hill & Westhumble station, any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before you book

  • Is the old sealant removed completely?
  • Is VAT in the price?
  • How the colour is chosen
  • What product goes in the joint
