How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Get a leaking seal dealt with right away
- Wipe joints with warm soapy water
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
How we handle new build mastic in Castle Green
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Common call-outs are for shower seals failing in the first year or two and worktop and upstand sealant coming away, on plot handovers, skirting & floors and bathrooms & en suites.
Work in a small place like Castle Green just needs the journey and access planning, and once on site, the job is the same as anywhere.
Our work is backed for twelve months.

Common problems we fix in Castle Green
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Signs it’s time to call us include:
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
- Cracked sealant around new window and door frames
Around Castle Green, as everywhere, new build mastic is only as good as the preparation behind it.

What affects the cost of new build mastic
You’ll get a clear quote before any work starts. It’s based on:
- The old material and how stubborn it is
- Mould in or behind the old joints
- When we can work, for business premises
- How many rooms, windows or areas are involved
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 we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved and give you a clear quote.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

We also work for property managers and facilities teams in Castle Green and across Surrey. Several sites can be quoted together.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
