If you have gaps where walls meet ceilings or slabs and fire stopping disturbed by later work, we can help, whatever the surface.
Work in a small place like Upper Clatford is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

What happens if it’s left?
For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. Older cottages and farmhouses around Upper Clatford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing.

New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.

When to call us in Upper Clatford
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
The most common problems we see are:
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
- New service routes left unsealed after building work
- Open joints along the top of partitions
Schools such as Balksbury Junior School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before you book
- How the colour is chosen
- How much experience the applicator has
- What insurance they hold
- Whether VAT is included
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Upper Clatford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
Do you certify the fire stopping?
Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and list the locations and products for you.

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’re given, installing the product to its tested details.
For buildings such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Andover station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- A wall that is not a fire-resisting element to begin with
- Issuing a fire rating or certificate for a building
- Problems with the door itself rather than the gap around the frame
