Customer's Feedback
Tate and David were wonderful to work with. They did our septic system for us. They were here when they said they would and went above and beyond great communication would definitely use them again.

I found Timberline to be a great company to do business with. Tate replaced our septic system, He was on time and did over and above for our job. He finished the project on the day he said he would and maintained great communication through out the project. It is hard to find a company you can trust in this day and age and Timberline is one of those few business that do what they say. I highly recommend them.

Tate and his team were amazing to work with! We are building a new house and Tate was by far the easiest and most knowledgeable person that we dealt with. He did our foundation dig, backfill, shaped up our driveway, brought us gravel, laid and compacted it and so much more. He worked with us, gave expert advice, and kept us informed every step of the way. I would recommend Timberline Excavating to anyone!!
