New build mastic in Botley, done properly
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We work on bathrooms & en suites, kitchens and plot handovers, and common reasons people get in touch are sealant that never bonded to the surface and shower seals failing in the first year or two.
Homes around Botley range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
Whatever the size of the job, you get the same 12-month guarantee in Botley and across Oxfordshire.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not wait for the house to settle if water is getting through
- Record problems with dated photos
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
Do you need new build mastic in Botley?
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
Most people get in touch after spotting one of these:
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
Around Botley, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Botley: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Oxford station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
DIY versus a professional finish
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

What else we do in Botley
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes anything from a few hours to several days, depending on the number of plots. For a job in Botley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

Advice
Why it’s worth doing now in Botley
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can call 0345 464 0079 or send us an email with a few photos and we will tell you. In a smaller place like Botley, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Colour agreed with you before we start

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Do you cover smaller places like Botley?

Why has my new-build shower seal failed already?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
What does new build mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you insured?
Yes. We’re fully insured.
Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. Once that’s done, or if they will not put it right, we can reseal it properly.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
