New build mastic in Holybourne, done properly
We work in new homes and on new-build sites across Holybourne. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you’re dealing with messy sealant that spoils new finishes and beads laid onto grit and dust from the build, we can help.
Around Holybourne, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Whatever the size of the job, you get the same one-year guarantee in Holybourne and across Hampshire.

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Holybourne, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive

When it isn’t the sealant
New sealant can’t fix everything, and we will tell you before any work starts. It will not solve:
- Your warranty claim itself, which is between you and the builder
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Bathrooms & en suites
- Show homes
- Kitchens
- Windows & doors
- Skirting & floors
- Plot handovers
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Wait for the cure time before using a resealed shower
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
