What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before we start. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In a small place like Great Shefford, access is usually 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.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Preparing for the visit
- Move anything stored near the joints

Fire rated sealant in Great Shefford, done properly
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on door frames, service penetrations and plasterboard & masonry, and people most often call us about damaged fire sealant left by other trades and ordinary sealant used where a fire-rated product was needed.
Work in a small place like Great Shefford is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Every job comes with a 12-month guarantee, wherever you are in West Berkshire.

What else we do in Great Shefford
Fire rated sealant around Great Shefford
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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
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. Managing a site like Shefford C.E. Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

How the job changes by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for each gap size.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Photograph sealed gaps before they’re covered up
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
- Include hidden areas like risers in routine checks
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Work for landlords, hotels and businesses
If you manage several properties in or around Great Shefford, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Older cottages and farmhouses around Great Shefford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What affects the cost of fire rated sealant
The quote reflects the job in front of us. We take into account:
- Mould in or behind the old joints
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Where the property is
- The rough size of the job
- Any previous sealing or DIY work
Every job is quoted individually. Simply ring 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
