Common questions in Little Berkhamsted
Will you come out to Little Berkhamsted?
Yes, Little Berkhamsted is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Little Berkhamsted for fire rated sealant?

Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Can I use normal mastic around a pipe through a fire wall?
No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service, or ask us to do it.
How do I get a quote for fire rated sealant in Little Berkhamsted?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
How we handle fire rated sealant in Little Berkhamsted
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We are often asked to deal with standard silicone or caulk in a fire-stopping gap and sealant items on a fire risk assessment action list, on linear gaps, plasterboard & masonry and door frames.
Somewhere as small as Little Berkhamsted, 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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Advice
What fire rated sealant looks like in Little Berkhamsted
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Andrew, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Bayford station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Do you need fire rated sealant in Little Berkhamsted?
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.
Any of these means the joints need attention:
- Gaps flagged on a fire risk assessment
- Gaps where walls meet ceilings or slabs
- New service routes left unsealed after building work
- Unsealed gaps around fire door frames
For site and facilities teams at buildings such as Essendon CofE (VC) Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Why it’s worth doing now in Little Berkhamsted
A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Older cottages and farmhouses around Little Berkhamsted can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
