About our new build mastic in Duckett's Green
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. If you have shower seals failing in the first year or two and second-fix sealing on new plots, we can help.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover.
Big or small, you get the same 12-month guarantee.

How we quote for new build mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Whether there’s mould to deal with
- Access and height
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- If someone has resealed it before
- Where the job is, and your postcode
- How we’d reach the joints

The process
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours in a single home, depending on how much there is to do. In Duckett's Green, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit

New homes and floors in Duckett's Green

Why act early in Duckett's Green
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Duckett's Green, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before work begins.
Why Duckett's Green clients choose us
- Old sealant always removed completely

- We are fully insured

Do you need new build mastic in Duckett's Green?
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Common reasons people contact us include:
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
If you’ve bought a new home near Hornsey station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- When the joint can take water or movement
- How the colour is chosen
- How the joint is cleaned and prepared
- What insurance they hold
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Damaged fittings that need replacing
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Record problems with dated photos
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
