Different surfaces, different methods
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Make resealing part of every contractor’s brief
- Get damaged fire seals looked at promptly
- Don’t paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record.
Commercial buildings in Hamstead
For seaside hotels, guest houses and holiday lets around Hamstead, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you are given, installing the product to its tested details.
If you let a flat or house near Lymington Pier station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Hamstead questions
Can you help a landlord with a rental near Lymington Pier station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Is Hamstead in your area for fire rated sealant?
Yes. We work across London and the South East, and Hamstead is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work in flats, HMOs and commercial 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. Out-of-hours work can be arranged.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
What fire rating will the seal have?
We do not give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it with a record of each location.

Why act early in Hamstead
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 work involved is often modest. Older cottages and farmhouses around Hamstead can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
