How to look after the new joints
After the cure time, these simple habits help:
- Keep water off fresh sealant until it has cured
- Record problems with dated pictures
- Watch for new gaps as the house dries out
- Raise failed sealant with the developer while you are covered
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day before water reaches them.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
New build mastic for homes and businesses in Staines Green
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a seal that’s letting water through needs doing now. We work on bathrooms & en suites, show homes and plot handovers, and common reasons people get in touch are sealant work across a run of new homes and smeared, uneven beads picked up at snagging.
Older homes in small places like Staines Green often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Advice
Staines Green questions
Do you cover Staines Green for new build mastic?
Yes, Staines Green is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Will you come out to Staines Green?
Yes, Staines Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
What information do you need?
Tell us what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Why it’s worth doing now in Staines Green
A hairline gap at a skirting can wait, but water getting through 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 tell you. In a small place like Staines Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Colour picked to suit the job
- Tidy, careful work
- One-year guarantee on every job
- Anti-fungal sanitary silicone in wet areas

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
