Gutter installation in Decatur starts at the downspout

Decatur's Sanitary Sewer Backup Prevention Program pays 100 percent, up to $10,000, for an overhead sewer system for homeowners with wet weather backups. Homes in the program must also disconnect footing drains, sump pumps, downspouts and storm drains from the sanitary sewer, at the owner's expense.

For gutter installers in Decatur, that rule shapes the design. If an existing downspout feeds a buried line, a new system needs another place to send roof water, above ground and away from the house. We form the gutter, hang it and place each downspout. The pipe work itself belongs to a plumber. That holds for a house near Lake Decatur as much as for one across town: each downspout needs open ground to land on.

Sizing

Rain falls here on about 115 days a year.

Decatur averages 40.44 inches of precipitation spread over about 115 days. Frequent rain argues for the larger system, so we recommend 6 inch gutters with 3x4 downspouts over 5 inch and 2x3. Water leaves the roof faster, and the outlet is less likely to be the bottleneck.

What the program asks, and where we fit

The city's brochure sets out the rules. These are the parts that touch a gutter job.

01

Who the program is for

Homeowners who have had wet weather sewer backups. If that is you, ask the city about eligibility before you plan the gutter work.

02

What must be disconnected

Footing drains, sump pumps, downspouts and storm drains must be separated from the sanitary sewer, at the owner's expense.

03

What the city pays for

The overhead sewer system itself, up to $10,000. Gutters are not part of the program.

04

What we do

We design the roof side. Each downspout lands on open ground, positioned to drain away from the foundation, so there is no reason to tie it back into the sewer.

Where new gutters turn up in Decatur

Rain gutter installation in Decatur, IL tends to take three forms, since most houses here already have a roof.

  1. 01

    Additions and sunrooms

    A new roof section gets a run formed to its exact length and a downspout of its own.

  2. 02

    Garages and porches

    Detached garages and porch roofs are often left without gutters. We add a seamless run and plan where it discharges.

  3. 03

    Infill and new construction

    Only about 4 percent of homes have been built since 2000, so a new house here is an opening to design the downspouts around the lot from the start.

Experience was exceptional. Nathan explained the whole process, from the initial estimate through the installation. He didn’t try to sell a bunch of extras or talk over my head. He used concise layman’s terminology. The installation (even with rain delays). Went well. Truly an excellent experience that didn’t cost the church its foundation. Thank you for your work

Gutter installation questions in Decatur

What does a seamless gutter installation in Decatur, IL include?

A gutter installer in Decatur should measure each eave, then form .032 gauge aluminum into one continuous gutter on site, hang it on hidden brackets and set the downspouts. We size the system to the roof, which is why we recommend 6 inch gutters with 3x4 downspouts.

Do I have to change my downspouts for the sewer backup program?

If you are in the program, downspouts must come off the sanitary sewer. A new system can plan that from the start by sending each downspout to a surface outlet. Check eligibility and requirements with the city.

How is a gutter installation service in Decatur, IL different from replacement?

Installation adds gutters where there are none, such as an addition, a new roof edge or a bare garage. Replacement takes off a worn system and puts up a new one. If yours is the second case, see gutter replacement in Decatur.
