FAQs for Westcott

Do you cover Westcott for fire rated sealant?

Yes. We work across London and the South East, and Westcott is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.

Is Westcott within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How long will you be here?

As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we will say how long yours will take.

Do you take on fire stopping in schools and offices?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Are you insured?

Yes. We are fully insured.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant, to the product’s details. The door, its seals and closer are for a door specialist.

Can you seal over the old sealant?

No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

About our fire rated sealant in Westcott

We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. If you have open gaps behind door architraves and gaps left after a refit or conversion, we can help, whatever the surface.

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

What affects the cost of fire rated sealant

We do not publish a price list. The quote depends on:

  • Whether old sealant or filler has to be cut out
  • How many areas need sealing
  • How easy the joints are to reach
  • The product the joint needs

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What we need to know

To help us quote quickly, let us know:

  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel
  • Roughly how big the job is

We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or drop us an email with the details.

What we do, step by step

Before we leave, we go over the finished joints with you. The visit itself normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. For a village or hamlet like Westcott, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  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. We record what was done and flag anything that needs a different system.

How to prepare

  • Mention any tricky access
  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive

Advice

What we are called out for in Westcott

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

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

  • Old fire sealant that has split or come away
  • New service routes left unsealed after building work
  • Seals cut through by electricians, plumbers or data installers
  • Gaps filled with a product that is not fire-rated

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

What to look for in a quote

  • How long the guarantee is
  • Are they insured?
  • How long to leave it before use
  • Whether all the old sealant comes out first

10 questions to ask before booking

Why deal with it now?

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that does not depend on other work. Around Westcott, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

Why us?

  • Quality sealants from Arbo and Everbuild
  • 4.9 on Google from 180+ five-star reviews
  • Any old sealant cut out fully, not covered over
  • Fully insured

Workplaces and buildings in Westcott

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.

Letting a property close to Aylesbury Vale Parkway station? Then any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

When something else is needed

A few problems are outside what sealant work can do:

  • Openings too large for sealant, which need batts, boards or another system
  • Issuing a fire rating or certificate for a building
  • Assessing a building’s fire safety

Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
