Bathroom & kitchen resealing in Lewknor, Oxfordshire
Our applicators work in Lewknor on bath, shower, basin, wet room, worktop and sink resealing. Old sealant removed completely, joints prepared properly.
- Water getting behind the kitchen upstand
- A messy, uneven bead from a previous reseal
- Damp behind the bath or under the tray
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
About our bathroom resealing in Lewknor
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Lewknor. We are ARBOMaster approved and fully insured, and every job carries our 12-month guarantee. We work on sinks & splashbacks, shower trays & enclosures and baths, and the jobs we see most are leaks into the floor or ceiling below and a joint torn by a bath that flexes.
Around Lewknor, it’s houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Bathroom resealing in Lewknor: local notes
Most of the South East has hard water, so limescale builds up 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 Margaret, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
Lewknor is about 5 miles south of Thame, in Oxfordshire.

How to look after the new joints
Aftercare is simple:
- Keep an eye on the corners, where splits start
- Wait for the cure time we give you
- Move toiletries away from the joint
- Stick to a soft cloth and a mild cleaner
Have a look at the joints every few months. A small split or a corner lifting is easy to spot, and if anything looks wrong, just phone 0345 464 0079 or drop us an email.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
Do you need bathroom resealing in Lewknor?
No sealant lasts indefinitely. Daily water, heat and cleaning products slowly wear it down, so its life depends on how the room is used, cleaned and aired.
These are the problems we are asked about most:
- Splits where the tray meets the wall
- Lumpy, uneven sealant from a DIY attempt
- Mouldy sealant that has gone black
- Water escaping at the shower enclosure
For site and facilities teams at buildings such as Lewknor Church of England Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
What to look for in a quote

Why act early in Lewknor
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, turning a small job into a building repair. In a small place like Lewknor, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What you get with us
- Neat joints and a tidy finish
- Old sealant always removed completely
- A 12-month guarantee on all work
- Sanitary silicone with an anti-fungal additive in wet areas

How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take around two hours for one bath or shower, longer for a whole bathroom. In a small place like Lewknor, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- 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.
How to prepare
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
Baths
The long joint down the side of a bath is where most leaks start, especially under a shower. We finish it with a single, even bead of anti-fungal silicone.
Shower trays & enclosures
A tray that rocks will split any sealant. We check for movement before we reseal, and tell you if it needs re-bedding first.
