How we handle new build mastic in Wivenhoe
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. If you’re dealing with beads laid onto grit and dust from the build and cracks appearing as a new home settles, we can put it right, whatever the surface.
In and around Wivenhoe, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
Each job carries a 12-month guarantee, whatever its size.

When something else is needed
In fairness, some problems need a different trade:
- Leaking fittings rather than failed sealant
- Disputes or warranty claims with your builder
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
- Wipe joints with warm soapy water
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
What affects the quote in Wivenhoe
You will get a clear quote before any work starts. It takes into account:
- Which sealant suits the joint
- When we can work, for business premises
- Mould in or behind the old joints
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
When you contact us, these details help:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or send us an email.
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Wivenhoe, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.
