Gutters are often installed using aluminum gutter spikes and ferrules which can bend easily and work loose over time. Replacing them with steel gutter screws and rigid plastic ferrules provides a more secure alternative and will prevent them from pulling loose or sagging.
To replace gutter spikes with screws, simply remove the old gutter spike and insert the screw through the existing hole in the front of the gutter. Then use a cordless drill to drive the screw into a new hole in the fascia board. Snug the screw up to the gutter, being careful not to over tighten it.
