How we quote for new build mastic
Call for a quick quote. What matters most is:
- The size of the job
- Mould in or behind the old joints
- Whether the work is at height
- Any working-time requirements on site
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

DIY versus a professional finish
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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why act early in New Yatt
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around New Yatt, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
