Aluminum gutters come in two basic thicknesses: .027 and .032.  The difference is much more than the metal.  The heavier (.032) will withstand a ladder or severe weather much easier.  The price difference is minimal.  Always require the heavier weight. The gutter hangers should always be hidden with screws that penetrate 2″ into the fascia.  To carry wind, snow, ice etc.  Most gutter companies have very limited labor (installation) warranties.  You should require a 2-year warranty to cover seasonal variations.

Your single most important first step is to verify the company you have contracted with has public liability and Workmans Comp. insurance.  WARNING: Your homeowner’s insurance in most cases does not cover you from liability.  In addition, most states allow handymen, lawn men, sub-contractors, etc. to self-insure (This is a nifty way to say: “No Insurance”.  Be careful.)  Another true test of Craftsmanship is how the workman pitches (slopes) the gutters to drain the rainwater.  Industry standards suggest 1/4″ per 10 feet.  The critical tool is a level.  You can not accurately eyeball gutters’ slope.   Only a poorly trained installer eyeballs the slope.  Note installation of an advanced water filtration system (ie MasterShield)  allows the slope of the gutter to be nominal.  Be aware that when water goes around a turn, flow is reduced.
