What sealant work cannot fix
We will always be straight with you, so here’s what sealant can’t fix:
- Assessing a building’s fire safety
- Construction that doesn’t provide fire resistance on its own
- Problems with the door itself rather than the gap around the frame
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Plasterboard & masonry

Fire rated sealant around Yattendon
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.
If you look after a church, hall or community building such as Church of St Peter and St Paul, gaps around pipes and cables are worth checking after any building work there. If you look after a building such as Yattendon C.E. Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Why it’s worth doing now in Yattendon
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again when the building is next checked. Where a wall is exposed, as many are in small places like Yattendon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

What affects the quote in Yattendon
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- How much there is to do
- Whether there’s mould to deal with
- Whether the work is at height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- The type of property
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Different surfaces, different methods
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance so residents know what to expect.
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard for the gap we’re sealing.
How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Yattendon, 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.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
How to prepare
- Move anything stored near the joints
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
Do you have insurance?

Can you work in occupied buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Early starts or out-of-hours work can be arranged where it’s needed.
