Landlord and commercial work in Startop's End
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Workplaces and buildings in Startop's End
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, 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 All Saints, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Marsworth Church of England Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.

How to look after the new joints
To keep the joints looking good and working properly:
- Tell trades working in the building that fire seals must be put back
- Allow for resealing whenever new services are run
- Take photos of fire stopping before ceilings or boxing go back
- Report cracked or damaged seals as soon as you notice them
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.
What the job involves on each surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall.
Signs you need fire rated sealant in Startop's End
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Door frames with gaps between frame and wall
- New service routes left unsealed after building work
- Linear gaps at the head of walls
- Damaged fire sealant left by other trades
Rented homes near Tring station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions from Startop's End
Do you cover Startop's End for fire rated sealant?
Yes. We work across London and the South East, and Startop's End is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Startop's End?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will we have a record of what was sealed?
Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll say how long yours will take.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
