Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Around Lower Basildon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Fire rated sealant for homes and businesses in Lower Basildon
Bigger jobs can be worked through in stages, flat by flat or floor by floor. It gives you a list to keep with the building’s fire safety documents. Common call-outs are for open joints along the top of partitions and sealant items on a fire risk assessment action list, across service penetrations, linear gaps and flats & HMOs.
If you have holiday lets, a converted barn used for business or a community building near Lower Basildon, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Different surfaces, different methods
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Fire rated sealant in Lower Basildon: local notes
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
Rented homes near Goring & Streatley station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Walls or floors that weren’t built to resist fire
- Sign-off of the building, which sits with building control or your assessor
- Deciding what fire stopping a building needs
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Door frames
- Plasterboard & masonry
- Linear gaps
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
Do you need fire rated sealant in Lower Basildon?
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
These are the problems we’re asked about most:
- Joints picked up in a fire-stopping survey
- Damaged fire sealant left by other trades
- Gaps filled with a product that isn’t fire-rated
- Open joints along the top of partitions
If you look after a church, hall or community building such as St Bartholomew's Church, gaps around pipes and cables are worth checking after any building work there.

Yes. We are fully insured for every job we do.

Can you give us a record of the work?
Yes. We record the locations we have sealed and the products used.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Lower Basildon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Preparing for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
