Why act early in Hatherden
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Where a wall is exposed, as many are in small places like Hatherden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

About our fire rated sealant in Hatherden
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, with a record of the products and locations if you need one. If you have door frames with gaps between frame and wall and gaps left after a refit or conversion, we can put it right.
Work in a small place like Hatherden is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Every job is covered by our 12-month guarantee, wherever you are in Hampshire.

Hatherden questions
Is Hatherden within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do fire rated sealant in Hatherden?
Yes, Hatherden is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Where do you work from?
Mr Mastic is based in Crawley. We cover Hatherden and the rest of Hampshire, along with the rest of our area.
Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.
Can you tell me which gaps need fire stopping?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Do you have insurance?
Yes. We’re fully insured.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you fill the gap behind a fire door frame?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.
Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
Door frames
Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep pictures of seals that will be hidden
- Check whether a sealant can be painted before decorating over it
- Look in service cupboards and ceiling voids from time to time
- Never patch a fire seal with standard sealant
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, do not leave it for the next one. Get it sealed and recorded so the item can be closed.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Hatherden, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Signs you need fire rated sealant in Hatherden

Common reasons people contact us include:
- Seals cut through by electricians, plumbers or data installers
- Standard silicone or caulk in a fire-stopping gap
- Gaps where walls meet ceilings or slabs
- Open holes round services passing through fire walls
Community buildings like Christchurch are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
