Fire rated sealant for homes and businesses in Grovehill
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. We’re often asked to deal with standard silicone or caulk in a fire-stopping gap and linear gaps at the head of walls, across plasterboard & masonry, flats & HMOs and pipe & cable gaps.
In a smaller place like Grovehill, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why deal with it now?
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Around Grovehill, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Questions from Grovehill
Do you cover Grovehill for fire rated sealant?
Yes. We work across London and the South East, and Grovehill is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Hemel Hempstead station. Can you help?

Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Workplaces and buildings in Grovehill
Grovehill is part of Hemel Hempstead, one of the post-war new towns. Hemel Hempstead was planned with its own industrial and business areas, so there are offices, units and workplaces not far from home. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you let a flat or house near Hemel Hempstead station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Alexandra Road Congregational Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Aftercare tips
Aftercare is simple:
- Never patch a fire seal with standard sealant
- Include hidden areas like risers in routine checks
- Check whether a sealant can be painted before decorating over it
- Photograph sealed gaps before they’re covered up
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. A visit to Grovehill is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- Where the tested detail needs backing or fill, we fit 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.
How to prepare
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’re 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 doesn’t work out, we can still put it right.
What we cannot put right
In fairness, some problems need a different trade:
- A wall that isn’t a fire-resisting element to begin with
- Deciding what fire stopping a building needs
- Issuing a fire rating or certificate for a building
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Plasterboard & masonry
- Linear gaps
- Pipe & cable gaps

Common problems we fix in Grovehill
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
These are the problems we are asked about most:
- Linear gaps at the head of walls
- Standard silicone or caulk in a fire-stopping gap
- Open holes round services passing through fire walls
- Damaged fire sealant left by other trades
For site and facilities teams at buildings such as South Hill Primary School, service openings in fire-resisting walls need checking after any refurbishment.
