New-build mastic & snagging in Shepperton Green, Surrey
New-build sealant joints in Shepperton Green need attention? We remove the old material, prepare the joints and seal them properly.
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
New build mastic in Shepperton Green, done properly
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We’re often asked to deal with untidy sealant flagged on a snagging list and new-build shower sealant that has already split, across bathrooms & en suites, windows & doors and show homes.
If you’ve bought a new home in or near Shepperton Green, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
All our work is covered by our one-year guarantee.

What new build mastic looks like in Shepperton Green
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Shepperton station, the sealant around baths, showers and frames is worth checking in the first year or two.

What affects the cost of new build mastic
For a quick quote, just ask. The main things that affect it are:
- Whether the work is at height
- The old material and how stubborn it is
- The number and length of the joints
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- How many joints, rooms or windows are involved
- Whether it has been sealed before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.
Why deal with it now?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a smaller place like Shepperton Green, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
