FAQs for Charney Bassett
Is there a guarantee on new build mastic in Charney Bassett?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Charney Bassett?
Yes. Charney Bassett is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule. Tell us the plots and the joints involved and we will quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
New build mastic in Charney Bassett
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on windows & doors, show homes and skirting & floors, and people most often call us about internal frame sealant that has split and joints pulling apart as timber shrinks.
Work in a small place like Charney Bassett just needs the journey and access planning, and once on site, the job is the same as anywhere.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Surface by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
New build mastic in Charney Bassett: local notes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Charney Bassett, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For jobs in and around Charney Bassett, choosing the right material for each joint is as important as a tidy finish.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Avoid scourers and strong chemicals on sealant
- Keep pictures and emails about snagging items
- Wait for the cure time before using a resealed shower
- Watch for new gaps as the house dries out
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Should I try it myself 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 doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Why act early in Charney Bassett
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Older cottages and farmhouses around Charney Bassett can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
