    Chicks N Chips from Sprucedale

  • “Darryl serviced our main fireplace after a competitor suggested we would have to replace the product completely! Big difference! He knows what he’s doing. Very professional, competent, and most importantly – he does what he says he’s going to do when he says he’s going to do it. We will happily recommend him to anyone who asks."

    Ron McIntosh from Bracebridge

  • "We had two propane wall furnaces stop working. The main level unit has had issues for a couple of years and the upstairs unit just recently stopped. Darryl came out on a Saturday at 5 pm. Spent a couple of hours with the main level unit, figured out it had never been installed correctly and fixed the problem (finally).The upstairs unit just needed a part cleaned and he got it going. Great job! Great Guy!"
