Common questions in Milton
Do you take on hotel work around Milton?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
I let a flat near Fratton station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you work in Milton?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Milton.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What colours of sealant can you use?
We can use white, clear or a colour to suit. Where the joint is on show, we match it to the surface.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
Where are you based?
We work from Crawley. We cover Milton and the rest of Portsmouth.

What else we do in Milton
When something else is needed
A few problems are outside what sealant work can do:
- A tray or bath that’s cracked through
- Cracked or missing grout between tiles (that’s regrouting)
- Movement from a bath with loose feet or no proper support
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Kitchen worktops & upstands
- Baths
- Wet rooms
- Basins & vanity units
- Shower trays & enclosures
- Sinks & splashbacks
DIY versus a professional finish
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 fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Bathroom resealing around Milton
Milton 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.
In the older streets around Church of St James, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as Meon Junior School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Milton is about 1 mile south-east of Portsmouth, in Portsmouth. Whether you are in the middle of Milton or further out, we cover bathroom resealing for every kind of property, from flats and houses to offices and hotels. Our Portsmouth coverage runs to 19 places, Milton among them.

Quotes for bathroom resealing in Milton
We quote each job individually. These are the things that affect it:
- The product the joint needs
- How much there is to do
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Whether it’s a home or a business
- Whether it has been sealed before
- The problem you’ve noticed
- How we’d reach the joints
For a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Milton and across Portsmouth. We can quote a run of properties together, and we’re fully insured.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Why deal with it now?
A failed joint gets more costly to put right the longer it’s left. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, and that is a far bigger job than a reseal. Around Milton, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen, and we explain the cure time before we leave. A visit to Milton is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We cover the area around the joints we’re working on.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Mention any tricky access

Advice
What we are called out for in Milton
Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, and a joint that looked fine soon begins to come away.
Signs it’s time to call us include:
- New sealant laid over old sealant that is now lifting
- Smears of silicone across the tiles
- Water getting behind the kitchen upstand
- Failed sealant on the screen profile
Rented homes near Fratton station change hands often, and a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
