Question DetailsAsked on 9/21/2011

Who do I ask to fix exterior drainage? Drain goes through old stone wall, nothing coming through, leaking into foundation? Plumber?Mason?

I don't know what Subcategory to put this in!

2 gutter spouts go underground to I don't know where, there is a drain in a sidewalk on the side of the house and a drain from a stone wall onto the driveway where a lot of water flowed out from during heavy rain. Now this drain is apparently backed up. There is leaking into the foundation of the garage floor (garage is partly underground) but not as much as used to flow from the stone wall drain. Worried.

Someone told me to call Rotor Router but they are horribly expensive and this may require extensive digging or drilling through stone wall. Yikes.

If somebody went through the trouble to run downspouts underground, then there was probably some sort of system for carrying the water away. It might be underground cast iron, pvc, or drail tile type piping and it may dump the water into the storm sewer system or into a drainage ditch. It might even dump the water into the sanitary sewer system, although this no longer meets code in many areas. It could even dump the water into a "French drain", which is basically a hole or trench filled with stones so that water can be temporarily stored until it dissipates into the ground.

By removing the downspouts, you'll gain access to the piping. It's likely that the piping starts at the downspouts at the rear of the house and then travels along side the house towards the front where it would pick up any more downspouts along the way.

I would have somebody snake out those underground pipes. They may have become plugged with sticks or wood chips or any other kind of yard debris. They could also have roots from nearby plants/trees plugging the pipes.

You may want to look for a local handy man or a plumber who is willing to do the work. Figure it will cost $50 or so for the equipment and then another 2-4 man hours to complete the job at anywhere from $30-$100 per hour. I wouldn't expect to pay anything less than $300 for a job like this. Others may want twice that.
