DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we handle fire rated sealant in Lye Green
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We work on linear gaps, pipe & cable gaps and service penetrations, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and open gaps behind door architraves.
For a small place like Lye Green, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
- Keep photos of seals that will be hidden
- Include hidden areas like risers in routine checks
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
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 list grows.

Lye Green questions
I let a flat near Berkhamsted station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Lye Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do you take on fire stopping in schools and offices?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Commercial buildings in Lye Green
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a building such as Brushwood Junior School, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as St George's Church, service openings in its walls need the right fire-rated sealant, as in any building.

Common reasons people contact us include:
- Holes left by a change of layout
- Cracked or shrunken fire-rated sealant
- Open gaps behind door architraves
- Damaged fire sealant left by other trades
For landlords with property near Berkhamsted station, any gap left by new services in shared walls should be closed with a fire-rated product.

What happens if it’s left?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Older cottages and farmhouses around Lye Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
