What happens on the day
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job usually takes a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. For a job in Stanwell, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Mention any tricky access
- Clear the area around the work
- Tell us about any water getting in

What affects the cost of fire rated sealant
The price is agreed before any work begins. It takes into account:
- How much there is to do
- Any mould that needs treating
- The old material and how stubborn it is
- The number of rooms or windows
Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.
Asking for a quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
Common questions in Stanwell
Will you come out to Stanwell?
Yes, Stanwell is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Ashford Surrey station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you have insurance?
Yes. We’re fully insured.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What does fire rated sealant cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Is there a guarantee?
Yes. Every job comes with our 12-month guarantee.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Commercial buildings in Stanwell
There are hotels and other places to stay in and around Stanwell. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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 landlords with property near Ashford Surrey station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Stanwell Fields CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.

We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.
What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. In a smaller place like Stanwell, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.

What else we do in Stanwell
Common problems we fix in Stanwell
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
These are the problems we are asked about most:
- Seals cut through by electricians, plumbers or data installers
- New service routes left unsealed after building work
- Standard silicone or caulk in a fire-stopping gap
- Unsealed gaps around fire door frames
Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
Questions to ask before booking
- Are they insured?
- Whether VAT is included
- When the joint can take water or movement
- How much experience the applicator has
Aftercare tips
After the cure time, these simple habits help:
- Get damaged fire seals looked at promptly
- Never patch a fire seal with standard sealant
- Ask every contractor to reseal any fire stopping they disturb
- Keep photos of seals that will be hidden
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we’ll tell you which one you have.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.
