What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:

- The old material and how stubborn it is
- When we can work, for business premises
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

New build mastic for homes and businesses in Newchapel
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Common call-outs are for cracks appearing as a new home settles and sealant applied over dusty or wet surfaces, on skirting & floors, windows & doors and plot handovers.
Older homes in small places like Newchapel often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, large or small.

Can you reseal over the builder’s sealant?

Where is Mr Mastic based?

Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we’ll quote. We will tell you if anything on it isn’t a sealant job.
Surface by surface
Show homes
We seal show-home bathrooms, kitchens and frames. We will plan around viewing times.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we can’t put right
To be straight with you, there are a few things sealant won’t fix:
- A tray or bath that isn’t properly supported, until it’s fixed
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
