DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
New build mastic for homes and businesses in Ashton Green
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you’re dealing with frame joints opening as the plaster dries and messy sealant that spoils new finishes, we can help, on bathrooms & en suites, skirting & floors and kitchens alike.
Older homes in small places like Ashton Green often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
There’s a 12-month guarantee on every job, whatever its size.

Different surfaces, different methods
Bathrooms and en suites

Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
- Cracking that points to a structural problem

How to look after the new joints
A little care helps the new joints last. We recommend:
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
- Don’t wait for the house to settle if water is getting through
- Keep water off fresh sealant until it has cured
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.
