New build mastic for homes and businesses in Upton
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We are often asked to deal with worktop and upstand sealant coming away and joints pulling apart as timber shrinks, across bathrooms & en suites, skirting & floors and kitchens.
In a village or hamlet like Upton, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Avoid scourers and strong chemicals on sealant
- Get a leaking seal dealt with straight away
- Watch for new gaps as the house dries out
- Keep pictures and emails about snagging items
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you so report it promptly.

Why act early in Upton
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Upton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.

- More than 20 years in sealant work
- We are fully insured
- Sealant colour chosen to suit
- A 12-month guarantee on all work
Take a look at how sealant jobs are priced and what customers say.
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
