New-build mastic & snagging in Halfway, West Berkshire
Problem with your new-build sealant joints in Halfway? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

- Sealant that never bonded to the surface
- Frame joints opening as the plaster dries
New build mastic in Halfway, done properly
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on skirting & floors, bathrooms & en suites and kitchens, and people most often call us about kitchen sealant that has pulled off the wall and cracked sealant around new window and door frames.
Older homes in small places like Halfway often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Different surfaces, different methods
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.

Signs you need new build mastic in Halfway
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
These are the problems we are asked about most:
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
Around Halfway, as everywhere, new build mastic is only as good as the preparation behind it.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Ventilate bathrooms well, especially in the first year
- Record problems with dated pictures
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
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 and the new finishes intact.
Landlords, agents and businesses in Halfway
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. In a small place like Halfway, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
