Joints and finishes in Chalgrove homes

How we handle new build mastic in Chalgrove
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation, because that’s what rushed new-build sealant normally lacks. If you’re dealing with second-fix sealing on new plots and sealant applied over dusty or wet surfaces, we can help.
Where new homes go up in smaller places like Chalgrove, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
There’s a 12-month guarantee on every job, large or small.

What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In a smaller place like Chalgrove, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What happens on the day
The work is kept neat and contained to the joints we’re treating. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. Parking around Chalgrove is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Questions from Chalgrove
Will you come out to Chalgrove?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Chalgrove in your area for new build mastic?
Yes. Our work covers London and the South East, and Chalgrove is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Is the work guaranteed?
Yes. All our work carries our 12-month guarantee.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
What should I tell you?
Let us know what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
Common problems we fix in Chalgrove
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Any of these means the joints need attention:
- Beads laid onto grit and dust from the build
- Internal frame sealant that has split
- Second-fix sealing on new plots
- Messy sealant that spoils new finishes
In and around Chalgrove, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep water off fresh sealant until it has cured
- Ventilate bathrooms well, especially in the first year
- Put sealant faults on your snagging list early
- Record problems with dated photos
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Movement caused by a poorly fitted tray or bath
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
