How we handle new build mastic in Wellhouse
Across Wellhouse, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. Typical jobs include new-build shower sealant that has already split and sealant that never bonded to the surface, across windows & doors, plot handovers and bathrooms & en suites.
In a village or hamlet like Wellhouse, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Whatever the size of the job, you get the same 12-month guarantee.

What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. Somewhere like Wellhouse needs a little journey planning: 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.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- 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.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky

When to call us in Wellhouse
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
Common reasons people contact us include:
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
In and around Wellhouse, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
How the job changes by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Wellhouse, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Why Wellhouse clients choose us
- Old sealant always removed completely
- Fully insured
- An ARBOMaster approved applicator
- White, clear, grey or coloured to suit, where the product allows

What new build mastic looks like in Wellhouse
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Why does sealant fail so quickly in new builds?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room and agree it with you.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
