Remedial sealant around Denmead
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Schools such as Denmead Junior School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near Cosham station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Remedial sealant for homes and businesses in Denmead
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that will not fix it. We are often asked to deal with wide, uneven beads that look worse than the old ones and beads that never stuck properly, on expansion joints, failed movement joints and shrunken worktop sealant.
In a smaller place like Denmead, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
You get a one-year guarantee, the same in Denmead as everywhere else we work.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many layers have to come out. Parking around Denmead is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

Common questions in Denmead
Do you cover smaller places like Denmead?
Yes, Denmead is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Cosham station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What if the leak is not the sealant?
You will hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we won’t pretend it will.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long does the work take?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. We’ll give you a timescale when we quote.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What affects the quote in Denmead
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- How many rooms, windows or areas are involved
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
When you contact us, these details help:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- Where the property is
We quote each job on its own, so the first step is telling us about yours. Simply ring 0345 464 0079 or email us and describe the job.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep the room well ventilated
- Ask why a joint failed before redoing it
- Keep an eye on the ceiling below the bathroom
- Act on a lifting corner straight away
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Work for landlords, hotels and businesses
We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What we’re called out for in Denmead
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
People usually contact us after spotting something like this:
- Dark patches showing through the sealant
- Leaks that keep coming back after resealing
- Sealant peeling off a dusty or damp surface
- A second bead peeling off the first
Homes close to Church of All Saints include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What your quote should include
- What happens if they find a problem under the old sealant
- How long the guarantee is
- What product goes in the joint
- Is VAT in the price?
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Tiles that have come away from the wall
- Plumbing leaks behind walls or under trays
- Cracks in the fitting rather than the joint
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
