To begin with: 80% of all installed seamless gutters are made out of aluminum. The cost of painted aluminum seamless gutters ranges from $10 to $14 per installed linear foot, depending on the specifics of your project like the height of your home, the number of stories, ease of accessibility (the roof edges of a 3-story multi-family house might be harder to access compared to a single-story home's roof edges), the location of your home, and the overall size of your project.
It will cost $2,000 to $2,500 for a typical project where 170 to 225 feet of seamless aluminum gutters are installed along with 6 downspouts on a one-story home.
The costs above will include gutters, end caps, hanging brackets, downspouts, and other accessories, in addition to professional installation costs and warranty.
Note that normally a two-story house will cost $1 more per linear foot of installed seamless gutters compared to single-story houses.
The biggest factor in how much gutters cost is the material that you select.
Due to their longevity, corrosion resistance, flexibility, and being lightweight, aluminum seamless gutters are well-known for offering great value and are the most popular choice by far for residential applications.
Coated or galvanized seamless gutters cost around $9 per installed linear foot but have the lowest level of durability.
Copper gutters are expensive, and average around $24 per installed linear foot, but are unsurpassed when it comes to durability and beauty.
