Chimneys are often the most exposed part of a property. Over a period of time pointing & flaunching can fail allowing rain to penetrate into the stack.
If sorted in time, new weather flaunching to the top & new pointing will extend the life of the stack.
Dependant on the seriousness of your chimney it may be necessary to completely knock down & rebuild the stack.
Sky Roofing Hertford Limited can provide a wide range of options to help you cure your problem.
Here is just some of our recent chimney work we have undertaken around Hertford & surrounding areas (before and after shots).
