What the job involves on each 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, and tell you if sealant alone is not the right fix.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run leaving no stretch unsealed.
Fire rated sealant for homes and businesses in Boldre
Bigger jobs can be worked through in stages, flat by flat or floor by floor. It gives you a list to keep with the building’s fire safety documents. We work on door frames, service penetrations and linear gaps, and the jobs we see most are old fire sealant that has split or come away and gaps where walls meet ceilings or slabs.
If you have holiday lets, a converted barn used for business or a community building near Boldre, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Boldre questions
Can you do fire rated sealant in Boldre?
Yes, Boldre is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Do you cover smaller places like Boldre?
Yes. Boldre is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or drop us an email.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Boldre, along with the rest of our area.
Do you work in flats, HMOs and commercial buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Out-of-hours work can be arranged where it’s needed.
How long will you be here?
Most jobs take a few hours for a handful of gaps, and longer for a whole building. We will confirm how long when we quote.

Do you need fire rated sealant in Boldre?
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common particularly when it was the last job before handover.
If you can see any of these, it’s time to have the joints looked at:
- Ordinary sealant used where a fire-rated product was needed
- Fire seals that have cracked with movement
- Gaps where walls meet ceilings or slabs
- Gaps left after a refit or conversion
For site and facilities teams at buildings such as William Gilpin Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before you book
- How much experience the applicator has
- Whether all the old sealant comes out first
- What the cure time is
- What guarantee comes with the work
How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work normally takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Boldre, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts

Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- A wall that is not a fire-resisting element to begin with
- Deciding what fire stopping a building needs
- Big openings where sealant alone is not the tested solution
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Service penetrations
- Linear gaps
- Pipe & cable gaps

Aftercare tips
After the cure time, these simple habits help:
- Make resealing part of every contractor’s brief
- Check risers, ceiling voids and cupboards during building checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Plan fire stopping into any work that goes through walls or floors
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.

What fire rated sealant looks like in Boldre
If you run a hotel, guest house or holiday let in a coastal place like Boldre, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 work to the specification you’re given, installing the product to its tested details.
Rented homes near Lymington Town station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Saint Nicholas Chapel, gaps around pipes and cables are worth checking after any building work there.

Why act early in Boldre
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Older cottages and farmhouses around Boldre can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
