- Linear gaps at the head of walls
- Holes left by a change of layout
- Old fire sealant that has split or come away
- Ordinary sealant used where a fire-rated product was needed
Letting a property close to Apsley station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Fire rated sealant for homes and businesses in Hemel Hempstead
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and people most often call us about unsealed gaps where pipes and cables go through a wall and open gaps behind door architraves.
Places to stay in a town like Hemel Hempstead need their bathrooms kept in order without closing the building. Work can be planned room by room, and out of hours where needed, so only part of the building is affected at a time.
Big or small, you get the same 12-month guarantee.

DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Questions from Hemel Hempstead
Is Hemel Hempstead in your area for fire rated sealant?
Yes. We work across London and the South East, and Hemel Hempstead is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Apsley station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one option among several. We use whichever the specification and tested details call for.
Is standard sealant good enough for a fire gap?
No. It looks sealed but won’t perform as fire stopping. A tested fire-rated product is needed and we can apply it for you.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
Do you work in flats, HMOs and commercial buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we will plan the work to suit.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, large or small.
Where are you based?
We work from Crawley. Our applicators cover Hemel Hempstead, along with the rest of our area.
Commercial buildings in Hemel Hempstead
Hemel Hempstead was built as one of England’s 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. 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.
For buildings such as St Barnabas, gaps around pipes and cables are worth checking after any building work there. Schools such as Broadfield Academy are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Keeping the joints in good condition
So the new joints stay in good condition:
- File the fire-stopping record where your assessor can find it
- Include hidden areas like risers in routine checks
- Plan fire stopping into any work that goes through walls or floors
- Flag any open gap you spot round a pipe or cable
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Why act early in Hemel Hempstead
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. In flats, shops and offices in Hemel Hempstead, a failed joint can let water into the unit below or behind a wall, where it can go unnoticed until the damage is done.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

- Homes, businesses and hotels
- Tidy, careful work
