What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are for a typical job. Somewhere as small as Greenham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Getting ready for the visit
- Mention any tricky access
- Let us know about parking restrictions
- Tell us about any water getting in

Advice
About our fire rated sealant in Greenham
We often work from an action list drawn up by a fire risk assessor on buildings across Greenham. Send us the list or the survey and we will quote for the fire-rated sealant work on it. Common call-outs are for ordinary sealant used where a fire-rated product was needed and sealant items on a fire risk assessment action list, on door frames, service penetrations and pipe & cable gaps.
Somewhere as small as Greenham, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
Every job comes with our 12-month guarantee, wherever you are in West Berkshire.

When something else is needed
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Walls or floors that weren’t built to resist fire
- Openings too large for sealant, which need batts, boards or another system
- Fire risk assessments, which need a qualified assessor
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

How to look after the new joints
After the cure time, these simple habits help:
- Include hidden areas like risers in routine checks
- Tell trades working in the building that fire seals must be put back
- Keep the record of products and locations with your fire safety documents
- Report cracked or damaged seals as soon as you notice them
Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Fire rated sealant around Greenham
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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. There are hotels and other places to stay in and around Greenham. Hotel work can be planned room by room, with out-of-hours working where needed.
Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Schools such as The Willows Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. If you let a flat or house near Newbury Racecourse station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Greenham questions
I let a flat near Newbury Racecourse station. Can you help?
Yes, we work for landlords and letting agents. 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 Greenham within the area you cover?
Yes, Greenham is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Are you insured?
Yes. We are fully insured.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Is it worth trying 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.
Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before work begins.
Where are you based?
Mr Mastic is based in Crawley. We cover Greenham and the rest of West Berkshire, along with the rest of our area.
Why deal with it now?
Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again when the building is next checked. Around Greenham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What else we do in Greenham
Surface by surface
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. Each one is sealed to the product’s tested detail.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we’ll say if we spot a problem with them.
