Remedial sealant & repairs in Crofton, Hampshire

When to call us in Crofton
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. At that point it has to come out.
Most people get in touch when they notice one of these:
- Gaps opening along the back of the worktop
- Products that weren’t meant for the joint
- Repeat leaks from the same joint
- Over-sealed joints coming away
Homes close to Peel Common Mission Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before booking
- Is the old sealant removed completely?
- Whether VAT is included
- What preparation is included
- Whether the sealant suits the joint
About our remedial sealant in Crofton
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you call 0345 464 0079 or email us, along with when it was last resealed. We work on leaking tray & enclosure joints, botched or over-sealed joints and failed movement joints, and common reasons people get in touch are repeat leaks from the same joint and beads that never stuck properly.
Somewhere as small as Crofton, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
You get a 12-month guarantee, the same in Crofton as everywhere else we work.

How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for most joints, depending on how much old sealant has to come out in most cases. In a small place like Crofton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Advice
Questions from Crofton
Do you work for landlords with property near Fareham station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you cover Crofton for remedial sealant?
Yes, Crofton is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Water damage behind tiles that needs a tiler
- Movement from fittings that are not supported
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

Quotes for remedial sealant in Crofton
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The number and length of the joints
- How many areas need sealing
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 the work is at height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Photos by email, if that is easy
- Whether it has been sealed before
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved and give you a clear quote.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
- Air the bathroom so the sealant can dry
- Check ceilings under showers for marks
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Bathrooms and kitchens in Crofton
Crofton is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Fareham station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Crofton School, we reseal washrooms and kitchens in schools and businesses as well as homes.
