I contacted Lou Riddle from Riddle Environmental Services when I was preparing to sell my house in Scranton PA. Lou was the best contractor that I have ever worked with both professionally and personally. I live out of state and it was very difficult to find a reliable competent contractor. I hired Lou to take care of two problems to prepare the house for the sale: repair a drywall crack on a wall of the house and ensure there was no mold in the basement. Lou was so clear and detailed in his work and fair in his pricing and was so helpful in preparing the house for sale. I feel very fortunate to have worked with Lou and would highly recommend his business without reservations.
