DIY kit or professional repair?
Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is generally cheaper.
If you do try a kit, read the instructions carefully, and give it the full curing time. If it does not work out, we can still repair it properly.
