The repair method for holes in galvanized gutters depends on the size of the hole - ones that are smaller than the head of a nail can be patched with plastic cement, while those that are larger than the head of a nail need to be patched with sheets of galvanized steel.
Petar and his team all treated my home like it was their own. They work very hard, punctual, and very professional. Good tidy up when the job was done. Excellent service, highly recommend. Thank you Petar!
