Lyndhurst Fire Rated Sealant
Problem with your fire-stopping gaps in Lyndhurst? We remove the old material, prepare the joints and seal them properly.
- Open holes round services passing through fire walls
- Gaps where walls meet ceilings or slabs
- Seals cut through by electricians, plumbers or data installers
Keeping the joints in good condition
So the new joints stay in good condition:
- Store the list of sealed gaps with your building paperwork
- Look in service cupboards and ceiling voids from time to time
- Keep pictures of seals that will be hidden
- Tell trades working in the building that fire seals must be put back
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
How we handle fire rated sealant in Lyndhurst
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. If you have new service routes left unsealed after building work and unsealed gaps where pipes and cables go through a wall, we can help.
For a pub, café, guest house or shop in or near Lyndhurst, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. In a smaller place like Lyndhurst, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
How to prepare
- Mention any tricky access
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Advice
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant won’t do:
- Sign-off of the building, which sits with building control or your assessor
- Deciding what fire stopping a building needs
- Fire doors that need new seals, closers or hardware
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
What we seal
- Door frames
- Plasterboard & masonry
- Flats & HMOs
- Linear gaps
- Service penetrations
- Pipe & cable gaps
For landlords and businesses
We also work for property managers and facilities teams in Lyndhurst and across Hampshire. We can quote a run of properties together, and we are fully insured.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Questions from Lyndhurst

Yes. There’s a 12-month guarantee on every job, wherever you are.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
How long will you be here?
A typical job takes a few hours for a handful of gaps, and longer for a whole building, including the preparation. Your quote will say how long we expect yours to take.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

When to call us in Lyndhurst
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Look out for any of the following:
- Sealant items on a fire risk assessment action list
- Open holes round services passing through fire walls
- Gaps filled with a product that isn’t fire-rated
- Fire stopping disturbed by later work
For buildings such as Church of Our Lady and St Edward, older buildings that have had new heating or wiring often have service gaps worth checking.

Fire rated sealant in Lyndhurst: local notes
Lyndhurst has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. 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 let a flat or house near Ashurst New Forest station, any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as St Michael and All Angels CofE Infant School, fire-stopping around service openings should be restored whenever new services go in.

- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- The product the joint needs
- Whether the work is at height
