Check the local BBB (better business bureau) b4 investing in this gutter company.
Already have leafguard? May I suggest you inspect the job. Make sure the gutters are installed the correct length (not to short or to long). Make sure the interior brackets are put in as agreed (every 2 feet) not every 3 or 4 feet. Make sure the brackets are installed uniform and straight. Make sure there are grommets in all the screws used. Makes sure the brackets are undamaged or bent. Make sure there are no open or unsealed holes left in the back plate that buts the fascia board. Make sure the end caps are on true and square to the home and the gutter (use a "T" square to check). Make sure the downspout holes (in the gutter) are a true 3 inches by 4 inches and the downspouts are not squeezed or bent to fit the opening. Leafguard is NOT a member of the BBB's "Honor roll". The pacfic NW BBB discontinued that program many years ago. When I signed my contract with the company, it was a C-, not an "A" as the salesman stated.
Get up on a ladder and make sure u have a quality product and a quality instal, If Leafguard says the screws go into truss tails …make sure they are in the tails. If they claim to use 4 inch screws, make sure it's 4 in, not 3 inches. Check all the work.
In my case the installers left a mess on my roof and siding. Did property damage. The company played hard-ball, pushed the limits of making the customer jump thru every legal hoop to get a response or performance.
