Your questions about new build mastic in Newbury's
Will you come out to Newbury's?
Yes. Newbury's is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Wadhurst station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots. We will confirm how long when we 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.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
How we handle new build mastic in Newbury's
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 sealant actually sticks instead of bonding to the dust. We are often asked to deal with kitchen sealant that has pulled off the wall and smeared, uneven beads picked up at snagging, across kitchens, plot handovers and skirting & floors.
Work in a small place like Newbury's just needs the journey and access planning, and the work itself is the same as on any site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How to look after the new joints
After the cure time, these simple habits help:
- Open a window or run the fan after bathing
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
- Check bath and shower seals every few months as the house settles
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
What affects the quote in Newbury's
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- How easy the joints are to reach
- The number and length of the joints
- Whether there’s mould to deal with
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- How we’d reach the joints

What new build mastic looks like in Newbury's
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Newbury's, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Wadhurst station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or send us an email with a few pictures and we’ll give you a straight answer. Around Newbury's, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.

Related advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out 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 does not work out, we can still put it right.
