Basement started to smell and we thought our drain, from under the laundry tub to the drain in the floor, was to blame. Turned out our nearly century old pipes were to blame (with a little help from the old oak next door). Everything was replaced quickly and tidily in two days. The man who tied in our pipes from the kitchen drain to the laundry, laundry tub and downstairs washroom sink was an artist.
Would recommend them to anyone.
