What affects the quote in Three Ashes

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

  • How many rooms, windows or areas are involved
  • The number and length of the joints
  • Working hours on commercial sites
  • Whether there’s mould to deal with

Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

What to tell us for a quote

When you call or email, it’s useful to know:

  • The rough size of the job
  • The problem you’ve noticed
  • A few photos by email, if you can
  • The address or postcode of the job

For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.

How we handle fire rated sealant in Three Ashes

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. We’re often asked to deal with fire seals that have cracked with movement and sealant items on a fire risk assessment action list, across linear gaps, service penetrations and door frames.

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

Each job carries a 12-month guarantee, large or small.

Surface by surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.

Flats and HMOs

Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start so residents know what to expect.

Workplaces and buildings in Three Ashes

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For site and facilities teams at buildings such as Silchester Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of St. Mary are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. For landlords with property near Bramley (Hants) station, any gap left by new services in shared walls should be closed with a fire-rated product.

DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

How the visit works

You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere as small as Three Ashes, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  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.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Tell trades working in the building that fire seals must be put back
  • Report cracked or damaged seals as soon as you notice them
  • Look in service cupboards and ceiling voids from time to time
  • Allow for resealing whenever new services are run

Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.

Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

FAQs for Three Ashes

Do you cover Three Ashes for fire rated sealant?

Yes. We work across London and the South East, and Three Ashes is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.

Do you cover smaller places like Three Ashes?

Yes. Three Ashes 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.

Can I choose the sealant colour?

Most of the time, yes. We’ll explain which colours are available and agree one before work begins.

Is standard sealant good enough for a fire gap?

No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.

Will we have a record of what was sealed?

Yes. Every gap we seal is listed with the product used, so you have it on file.

Is there any odour?

Sometimes, a little. It fades as the sealant cures.

Can you work in occupied buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we’ll plan around it.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Work for landlords, hotels and businesses

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

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Why act early in Three Ashes

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a small place like Three Ashes, 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, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
