Professional Job and Cleanup

"Well our job is all finished. I want to thank everyone for such a professional job and cleanup. Adam, Justin and Paul were amazing and finished the eavestroughing and window installation without a hitch. Thanks to Adam for pointing out that the colour we had chosen was not the best match. He ordered the better choice and it was here on the job before they actually needed it. Thank you for not letting me put up the WRONG colour Adam."
