Dormers Wells Fire Rated Sealant
Our applicators work in Dormers Wells on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Damaged fire sealant left by other trades
- Joints picked up in a fire-stopping survey
- Gaps filled with a product that isn’t fire-rated
Surface by surface
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.
How we handle fire rated sealant in Dormers Wells
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That’s the part we focus on. Common call-outs are for open gaps behind door architraves and new service routes left unsealed after building work, on door frames, flats & HMOs and service penetrations.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Dormers Wells cannot close.
You get a one-year guarantee, the same in Dormers Wells as everywhere else we work.

Honest limits
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant will not put right:
- A wall that is not a fire-resisting element to begin with
- Large holes that need a different fire-stopping system
- Fire risk assessments, which need a qualified assessor
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal

The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Quotes for fire rated sealant in Dormers Wells
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- The number of rooms or windows
- Mould in or behind the old joints
- The old material and how stubborn it is
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.
Helping us quote
There’s no need for technical detail. Just tell us:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or email us.
Leave it or put it right?
Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Commercial buildings in Dormers Wells
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. 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.
Dormers Wells is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near Southall station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Common questions in Dormers Wells
Can you do fire rated sealant in Dormers Wells?
Yes. We work across London and the South East, and Dormers Wells is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Is parking a problem for a job in Dormers Wells?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you fill the gap behind a fire door frame?
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.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you work in occupied buildings?
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.
How do I get a quote for fire rated sealant in Dormers Wells?
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 work begins.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
