Common questions in Mount Pleasant
Do you cover Mount Pleasant for fire rated sealant?
Yes, Mount Pleasant is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Do you work for landlords with property near Cooksbridge station?
Yes, rental work is part of what we do. 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 it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How long does the job take?
A typical job takes from a few hours to a few days, depending on the number of gaps and the access. Your quote will say how long we expect yours to take.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
About our fire rated sealant in Mount Pleasant
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on door frames, plasterboard & masonry and service penetrations, and people most often call us about open holes round services passing through fire walls and old fire sealant that has split or come away.
If you have holiday lets, a converted barn used for business or a community building near Mount Pleasant, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Whatever the size of the job, it’s backed by our 12-month guarantee in Mount Pleasant and across East Sussex.

What the job involves on each surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the seal has something sound to bond to.
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist and we will mention anything we notice.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, 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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. Somewhere as small as Mount Pleasant, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Advice
Why act early in Mount Pleasant
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. In a small place like Mount Pleasant, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Why book with us
- A 12-month guarantee on all work
- Sanitary silicone with an anti-fungal additive in wet areas
- Neat joints and a tidy finish
- Any old sealant cut out fully, not covered over

When to call us in Mount Pleasant
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
Common reasons people contact us are:
- Open holes round services passing through fire walls
- Fire seals that have cracked with movement
- Damaged fire sealant left by other trades
- Holes left by a change of layout
Managing a site like Barcombe Church of England Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
What your quote should include
- Whether VAT is included
- How much experience the applicator has
- What product goes in the joint
- Are they insured?
Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Fire risk assessments, which need a qualified assessor
- Large holes that need a different fire-stopping system
- Construction that doesn’t provide fire resistance on its own
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
