How we handle new build mastic in Wellhouse
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on bathrooms & en suites, windows & doors and show homes, and common reasons people get in touch are messy sealant that spoils new finishes and beads laid onto grit and dust from the build.
Around smaller Scottish places like Wellhouse, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
A one-year guarantee comes as standard.

What new build mastic looks like in Wellhouse
The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Garrowhill station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Raise failed sealant with the developer while you’re covered
- Avoid scourers and strong chemicals on sealant
- Do not seal over failed sealant yourself
- Use the extractor fan every time you shower
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
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. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Keep an eye out for these signs:
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
- Kitchen sealant that has pulled off the wall
Around Wellhouse, as everywhere, new build mastic is only as good as the preparation behind it.

Common questions in Wellhouse
Do you cover Wellhouse for new build mastic?
Yes, Wellhouse is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Do you work for landlords with property near Garrowhill station?

Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
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 that suits the frame.
The process
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. For a place like Wellhouse, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention any tricky access
- Tell us about any water getting in
- Keep children and pets away from the work area

Why act early in Wellhouse
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. In a place like Wellhouse, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
