What affects the quote in Hammerwood
We quote each job individually. This is what makes a difference:
- The number and length of the joints
- Any working-time requirements on site
- Access and height
- The product the joint needs
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- The problem you’ve noticed
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- Where the property is

Fire rated sealant in Hammerwood
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and the jobs we see most are standard silicone or caulk in a fire-stopping gap and open holes round services passing through fire walls.
In a village or hamlet like Hammerwood, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
All of our work is guaranteed for twelve months.

Aftercare tips
So the new joints stay in good condition:
- Ask which product was used before you paint
- Include fire stopping when you schedule refits
- Ask every contractor to reseal any fire stopping they disturb
- Take pictures of fire stopping before ceilings or boxing go back
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.
Different surfaces, different methods
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before applying the sealant.

What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. Somewhere as small as Hammerwood, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

What fire rated sealant looks like in Hammerwood
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Managing a site like Sackville School? Then fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of St Stephen are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Hammerwood questions

Do you cover smaller places like Hammerwood?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Will you assess my building’s fire safety?
No, we do not assess buildings. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Do you do fire sealant around door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door, its seals and closer are for a door specialist.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Do you need fire rated sealant in Hammerwood?
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it is not fire-rated.
Any of these means the joints need attention:
- Fire stopping disturbed by later work
- Cracked or shrunken fire-rated sealant
- Linear gaps at the head of walls
- Unsealed gaps where pipes and cables go through a wall
Rented homes near Dormans station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote
