Cast iron guttering- is it easy to renovate?

Normally the joint is putty and a bolt. Remove old bolt by unscrewing with molegrips or cutting away. Make sure joint is dry and clean of old putty. Squirt in clear silicone and tighten back up with a new roofing bolt 30-40mm. Paint gutters with hammerite when dry.

Take too much to explain on forum how to go about it safely removing old cast iron safely it's a killer if it hits anyone.. So if interested as this forum doesn't allow email addresses go to Vehilce: caravans/motorhomes section select page 17 and quiestion THETFORD PORTA POTI BENCH TYPE WILL NOT FLUSH. In the answer is my email address email and I'll send details I've replace more guttering that I've had hot dinners.

Typically, the lengths of cast guttering were held together with a nut and bolt at the ends, and the water seal was formed with pitch soaked rope....naturally over time this has degraded, giving you those leaks. If you can cut the bolt away, you can get into the joint with a good squirt of silicone, but if this is impossible, use some self adhesive flashing tape over the inside of the joint. If you want to paint your gutters use black Hammerite - just make sure its a dry day! Personally, give me plastic anytime...!
