New build mastic in Thames Ditton, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on bathrooms & en suites, skirting & floors and windows & doors, and people most often call us about gaps between new skirting and floors and joints pulling apart as timber shrinks.
For a new home in or near Thames Ditton, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
All our work is covered by our 12-month guarantee, wherever you are in Surrey.

DIY sealant or a professional job?
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.
A careful DIYer can reseal a simple joint, 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.

Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Are you an approved applicator?

Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

When something else is needed
A few problems are outside what sealant work can do:
- Cracking that points to a structural problem
- Broken tiles or a split tray
- Leaking fittings rather than failed sealant
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
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 most come down to preparation. Around Thames Ditton, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

New build mastic in Thames Ditton: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Thames Ditton station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Ventilate bathrooms well, especially in the first year
- Raise failed sealant with the developer while you’re covered
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with straight away
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
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.
What we’re called out for in Thames Ditton
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
The problems people normally mention when they call include:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
Around Thames Ditton, as everywhere, new build mastic is only as good as the preparation behind it.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. For a job in Thames Ditton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- 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.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
