Very knowledgeable and polite, fair pricing, quick and efficient. Plan is to use them again for additional work to (finally) complete my vision for the rear of the property (long neglected by the prior owner).

During a tree service at my home on 3/21/25, Dorshak crew knowingly operated a bucket truck with an…read moreactive hydraulic fluid leak. This is a dangerous petroleum product that causes immediate permanent asphalt damage, environmental damage, and is extremely dangerous to people and animals. This resulted in a chemical spill up and down my 280'x12' driveway, onto to the road in front of my house, as well as a constant drip from where the truck was housed to my home (statute below). This incident has left deep-set stains (permanent) and potholes that need to be professionally repaired. Initially I had it cleaned enough to keep the oil from tracking into my house and to protect people and animals. This oil will cause immediate burns if touched and can be fatal if ingested. I was on-site and called their office to report the truck was leaking oil onto my driveway. The foreman told me they put cardboard under the truck where parked to "contain the oil". They did not leave my property when reported but continued to work which increased the amount of oil spilled onto my driveway. I took pictures up and down my driveway and asked the foreman to do the same, which he did. Mr. Dorshak called me early the next morning to send a crew to "clean it up" admitting liability but failed to report the spill which by state statute is mandatory. I needed special equipment and handling or the asphalt could be totally destroyed. From the date of the incident to present, the stains and potholes are up the middle of my driveway where they had not been before, and at the time were puddled on the road which my neighbors witnessed. This is negligence/property damage and several code violations by statute. For the permanent stains and potholes to my driveway Dorshak is legally and financially obligated to return my driveway to its original condition including stains and potholes. Mr. Dorshak will admit no liability while admitting his truck was leaking hydraulic fluid on public and private land which puts him at 100% liability. To date he has not paid me for damages. He wants me to pay for the tree service in full so he can dismiss the claim. STATUTE 49CFR - In WI a leaking hydraulic truck on private property and public roads is prohibited under WI HAZARDOUS SPILLS LAW and FEDERAL MOTOR CARRIER LAW which mandates that leaking vehicles cannot be safely operated or transported. As such, I would not recommend using their service.
