For a new home in or near St George's Hill, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Your questions about new build mastic in St George's Hill
Can you help a landlord with a rental near Weybridge station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Is St George's Hill in your area for new build mastic?
Yes, St George's Hill is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Where do you work from?
We work from Crawley. We cover St George's Hill and the rest of Surrey, along with the rest of our area.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
- Don’t wait for the house to settle if water is getting through
- Record problems with dated photos
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
When something else is needed
It helps to know what we can’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
- Disputes or warranty claims with your builder
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Advice
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around St George's Hill, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
