Your questions about fire rated sealant in Charlton
Will you come out to Charlton?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take on hotel work around Charlton?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you fill the gap behind a fire door frame?
Yes. The joint between frame and wall is sealed with a fire-rated sealant following the tested details. The door, its seals and closer are for a door specialist.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
How much does fire rated sealant cost in Charlton?
Size, access and the old material all affect the cost. Ask us for a quote.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used for your files.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It generally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Charlton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any parking rules near the property
- On commercial sites, let us know about site rules

Why deal with it now?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Around Charlton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Include fire stopping when you schedule refits
- Photograph sealed gaps before they’re covered up
- Check whether a sealant can be painted before decorating over it
- Include hidden areas like risers in routine checks
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
What affects the quote in Charlton
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Which sealant suits the joint

- How many rooms, windows or areas are involved

Fire rated sealant in Charlton: local notes
There are hotels and other places to stay in and around Charlton. 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
For buildings such as St Mary's Church, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Highbury Infant School and Nursery are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. If you let a flat or house near Hitchin station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
