New-build mastic & snagging in Cuckfield, West Sussex
New build mastic across Cuckfield and nearby, with old sealant always removed completely and a one-year guarantee.
- Worktop and upstand sealant coming away
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
How we handle new build mastic in Cuckfield
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that is what rushed new-build sealant generally lacks. We work on kitchens, skirting & floors and windows & doors, and common reasons people get in touch are gaps behind new kitchen upstands and new-build shower sealant that has already split.
Where new homes go up in smaller places like Cuckfield, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
- Don’t wait for the house to settle if water is getting through
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Do you need new build mastic in Cuckfield?
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Keep an eye out for these signs:
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
If you’ve bought a new home near Haywards Heath station, the sealant around baths, showers and frames is worth checking in the first year or two.

Related advice
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
