Leave it or put it right?
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. If a gap isn’t suitable for sealant, we will tell you. Around Graveley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Keeping the joints in good condition
Looking after new joints is easy:
- Never patch a fire seal with standard sealant
- Take photos of fire stopping before ceilings or boxing go back
- File the fire-stopping record where your assessor can find it
- Plan fire stopping into any work that goes through walls or floors
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
Workplaces and buildings in Graveley
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Stevenage station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as Graveley Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.

What else we do in Graveley
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Graveley, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap 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.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Advice
How the job changes by surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each, and tell you if sealant alone is not the right fix.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
