New build mastic for homes and businesses in Westborough
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, show homes and kitchens, and people most often call us about joints pulling apart as timber shrinks and kitchen sealant that has pulled off the wall.
In smaller places like Westborough, new homes tend to come as small developments or single plots. 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 will sort it.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Raise failed sealant with the developer while you’re covered
- Wipe joints with warm soapy water
- Do not seal over failed sealant yourself
- Don’t wait for the house to settle if water is getting through
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Honest limits
It helps to know what we cannot do too:
- Cracked trays, tiles or worktops
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

What we are called out for in Westborough
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Keep an eye out for these signs:
- Cracks appearing as a new home settles
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
If you’ve bought a new home near Guildford station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Whether all the old sealant comes out first
- Who turns up on the day
- Which sealant they’ll use, and why
- How long the guarantee is

Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered to the agreed spec.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
New homes and floors in Westborough
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours in a single home. In a smaller place like Westborough, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.

- Let us know if you’ve seen damp or leaks
