New-build mastic & snagging in Great Lea Common, West Berkshire
New-build sealant joints in Great Lea Common need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
How we handle new build mastic in Great Lea Common
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. We work on skirting & floors, bathrooms & en suites and show homes, and the jobs we see most are gaps behind new kitchen upstands and cracks appearing as a new home settles.
Around Great Lea Common, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job is covered by a 12-month guarantee, wherever you are in West Berkshire.

Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Great Lea Common can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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.

Looking after it afterwards
After the cure time, these simple habits help:
- Open a window or run the fan after bathing
- Follow the cure time we give you
- Wipe joints with warm soapy water
- Record problems with dated photos
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
