Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Landlords and letting agents in Clewer can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Dry the bead with a towel now and then
- Stick to a soft cloth and a mild cleaner
- Give the silicone its full cure time
- Keep bottles off the sealant line
Wipe up standing water along the worktop joint. The drier the joint stays, the longer it lasts.
A failed kitchen joint is easy to miss. Splashes run behind the back edge and soak into the worktop, and the board underneath can swell. Resealing before that happens protects the worktop.
Why act early in Clewer
A quick bead over the top of the old one might look better for a while, but it will not bond. It lifts, traps water and grows mould behind it, so the next person has twice as much to remove. In an older home around Clewer, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

How we quote for bathroom resealing
Every job gets its own quote. These are the things that affect it:
- The old material and how stubborn it is
- The number of rooms or windows
- Working hours on commercial sites
- Mould in or behind the old joints
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- Whether it’s a home or a business
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Common questions in Clewer
Is Clewer within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Windsor & Eton Central station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How long before the new sealant can get wet?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Leave it around 24 hours before it gets wet, or follow the cure time we give you.
Is white the only colour available?
White and clear are the most common choices, but other colours can be used to suit tiles and worktops. Tell us what you’d like when you get in touch.
Bathrooms and kitchens in Clewer
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings. Clewer has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For site and facilities teams at buildings such as St Edward's Catholic First School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Windsor & Eton Central station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

Should I try it myself first?
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 doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

When to call us in Clewer
Black mould is behind a lot of resealing. Bathrooms without good ventilation give mould all the damp it needs, and mould that has grown into the silicone usually will not clean off.
These are the problems we’re asked about most:
- Lumpy, uneven sealant from a DIY attempt
- A joint torn by a bath that flexes
- Shrunken sealant along the back of a worktop
- Damp behind the bath or under the tray
In the older streets around Church of St Andrew, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- How hidden problems are handled
- Whether VAT is included
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes two to three hours for a typical bath, depending on how much old sealant there is. Parking around Clewer is generally 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.
- We look at every joint first and check for movement or leaks.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- Joints are degreased and any mould is treated.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- The bead is tooled smooth and you are told the cure time, normally around 24 hours.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
