6 downspouts, 12 ft. avg rainfall....no clue...I am close to Milwaukee, WIDino - it's hard to tell without knowing some more details.
What's your catchment? Linear feet of guttering? Average rainfall/location?
no...other than the patio slab pitched towards my home I need to fix and the patio step that has bad waterproofing underneath it.Whether it's a good idea or not has a lot to do with wether or not you need them.
Do you have ground water problems? IE do you have water pooling around your house after a good summer storm? (Wow - we got flooded something fierce in the summer when I lived in the South West corner of Milwaukee county).
12 ft is the length of downspouts ....as you were requesting to know.dinosaur -
You do not have 12 feet of rain annually in Pewaukee. You probably have 30"-35" of moisture a year and about 20%-25% is in the form of snow. The problem you are looking at is because some of the rain comes from short storms giving you a maximum of 2" to 3" each, although you cannot rule out 8" storm once every 10 years.
Have the gutter sizes been enlarged?Is $350 a fair price to install 6 downspouts? I am upgrading from 3' to 4'. I wouldn't need downspout extensions.
I chose to pass. I think the contractor was just wanting to make some $$$ from us.Have the gutter sizes been enlarged?
Why are you putting larger leaders on the house? If the gutters are overflowing during a hard rain, just increasing the size of the leader won't cure the problem. You'd need to do both.
So this was his idea? Did he tell you why you needed this "upgrade"?I chose to pass. I think the contractor was just wanting to make some $$$ from us.
There was only one area out of the 6 downspouts that had a "little" freestanding water. He thought adding 4' all around would help. Yeah right.So this was his idea? Did he tell you why you needed this "upgrade"?
