New build mastic for homes and businesses in Princes Risborough
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. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. If you have worktop and upstand sealant coming away and joints pulling apart as timber shrinks, we can put it right, whatever the surface.
Where new homes go up in smaller places like Princes Risborough, 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.

What new build mastic looks like in Princes Risborough

When it isn’t the sealant

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few pictures and we will give you a straight answer. Around Princes Risborough, 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.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Don’t wait for the house to settle if water is getting through
- Resist patching a failed seal with a tube from the DIY shop
- Raise failed sealant with the developer while you’re covered
- Ventilate bathrooms well, especially in the first year
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.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Will you leave a mess?

Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If it is not sorted, or keeps failing, get in touch with us.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
