About our new build mastic in Newbury
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Typical jobs include sealant applied over dusty or wet surfaces and skirting joints opening in the first winter, across windows & doors, skirting & floors and show homes.
For a small place like Newbury, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job.

What else we do in Newbury
New build mastic around Newbury
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.
Around Newbury, as everywhere, new build mastic is only as good as the preparation behind it.
Newbury is about 3 miles south-east of Sittingbourne, in Kent. Across the ME9 area, our applicators can take on new build mastic. Across Kent, we cover 922 places, and Newbury is one of them. Chelmsford is on our list too, around 32 miles away.
Postcode districts we cover here for new build mastic: ME9.

Near you in Newbury
Around Newbury, our work takes us to homes and buildings near Cromers Wood and The Sittingbourne School. The nearest railway station is Teynham station, roughly 2.7 miles north-east of the centre. Nearby you will also find Sittingbourne Heritage Museum (2.4 miles north) and Newnham Castle (2.1 miles south-east).
Aftercare tips
So the new joints stay in good condition:
- Raise failed sealant with the developer while you’re covered
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
Why act early in Newbury
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Newbury can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What you get with us
- White, clear, grey or coloured to suit, where the product allows

Newbury questions
Is Newbury in your area for new build mastic?
Yes, Newbury is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
I let a flat near Teynham station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots. Your quote will say how long we expect yours to take.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What affects the quote in Newbury
Your quote is based on your job. We take into account:
- Working hours on commercial sites
- The amount of work
- Access and height
- Whether there’s mould to deal with
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- The rough size of the job
- Pictures of the joints, sent by email
- The type of property
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll come back to you with a quote.
When to call us in Newbury
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry.
If you can see any of these, it’s time to have the joints looked at:
- Sealant applied over dusty or wet surfaces
- Cracks appearing as a new home settles
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
If you’ve bought a new home near Teynham station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- The length of the guarantee
- Whether VAT is included
- When the joint can take water or movement
- How hidden problems are handled
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Newbury, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- 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
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
