FAQs for Merton
Can you help a landlord with a rental near Bicester Village station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Merton?
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.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long will it take to strip and reseal the joint?
It takes 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.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
What if resealing won’t fix my leak?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, and we will not reseal for the sake of it.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you fix expansion and movement joints?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Remedial sealant in Merton
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have thick, messy sealant smeared over tiles and leaks that keep coming back after resealing, we can help.
Around Merton, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What we can’t put right
Before you book, it’s worth knowing the limits too:
- Water damage behind tiles that needs a tiler
- Plumbing leaks behind walls or under trays
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Where we work in Merton
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Expansion joints
- Shrunken worktop sealant
- Failed movement joints
- Mouldy bath & shower sealant
What happens if it’s left?
Mould under a bead can’t be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. In a small place like Merton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why us?
- Every job guaranteed for a year
- You choose the colour before work begins
- Quality sealants from Arbo and Everbuild
- Neat joints and a tidy finish
What the job involves on each surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. In a small place like Merton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We give you the cure time and explain what caused the failure.
How to prepare
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
How to get a quote
Asking for a quote is easy: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

Bathrooms and kitchens in Merton
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.
Homes close to Church of St Swithin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Bicester Village station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Merton is about 3 miles south of Bicester, in Oxfordshire. Across the OX25 area, we can carry out remedial sealant at your property. Our Oxfordshire coverage runs to 443 places, Merton among them. For nearby work, see our Oxford page.
Here we cover the OX25 postcode area for remedial sealant. We also cover Fencott (1 mile south), Murcott (1 mile south-east), Charlton-on-Otmoor (1 mile south-west), Wendlebury (2 miles north-west) and Lower Arncott (2 miles east). We also work in nearby towns such as Oxford (8 miles south), Bicester (3 miles north), Abingdon-on-Thames (13 miles south), Witney (15 miles west), Thame (11 miles south-east) and Kidlington (6 miles south-west).
Around Merton
We work in homes and buildings around The Old Plough pub and the streets around them. The closest station to Merton is Bicester Village station, roughly 2.7 miles north of the centre. A little further out are Bicester Community Hospital (2.9 miles north) and Bicester Avenue (2.3 miles north). The countryside around Merton includes Graven Hill and Woodsides Meadow.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What else we do in Merton
How we quote for remedial sealant
We do not publish a price list. The quote depends on:
- The old material and how stubborn it is
- When we can work, for business premises
- How easy the joints are to reach
- The number of rooms or windows
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Asking for a quote
To make quoting easier, please include:
