Remedial sealant in Newfound: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Oakley Infant School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For landlords with property near Basingstoke station, botched sealant from a previous quick fix is easier to strip out between tenants.

Newfound questions
I let a flat near Basingstoke station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is Newfound within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Can you fix a reseal that hasn’t worked?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What do you need from me for a quote?
Let us know what needs doing and where, plus photos if you have them. If we need more, we will ask.
Why act early in Newfound
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Newfound can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

How we quote for remedial sealant
You will get a clear quote before we start. It’s based on:
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
To make quoting easier, let us know:
- The type of property
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.
Signs you need remedial sealant in Newfound
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Most people get in touch when they notice one of these:
- Wide, uneven beads that look worse than the old ones
- Torn expansion joints
- A shower that leaks however often it’s resealed
- Dark patches showing through the sealant
Homes close to St John's include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

The process
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Newfound, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Advice
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
