We need to have our plumbing all redone in our 1930's bungalow - there is not a ton of it - just one bath, kitchen, laundry- but it is so small - all 1/2 inch in and out of the house. Plus, when it was remodeled, they put the water for the laundry room on the OUTSIDE wall and it freezes all the time. Has anyone had this done that can recommend someone reliable and affordable (and INSURED)? Thanks!
