Knight's Excavating recently replaced our sewer line using the pipe busting method. They did a great job and were pleasant to deal with. The job required digging twice into the city street, but they did so without complaint. I should mention that they took great care in restoring our front yard/garden to its original state, including a gravel walkway with curved metal edging. The entire crew is hard-working, polite and very patient with questions and requests. I'd have no hesitation hiring them again. Recommended, to be sure. read more

Bob Knight does stellar work, with an eye for detail and literally years of local experience to back it up. We needed grading work to redirect water from impacting the foundation at the back of our house. And we wanted to have that water (and water from our downspouts) end up nicely in a rain garden out front. Bob knew exactly what to do for our situation and handled it all in three days, including building the rain garden. Bob gave us a fair price, kept his word throughout the process, didn't cut corners, and showed up when he said he would with his hard working team. He's a standup guy, to boot, and great to talk and consult with. We are pleased with the quality of the work and the straight talk. Wholeheartedly recommend Knight's Grading and Excavating. read more

Great experience with Knight's Excavating. They replaced our water line and did stellar work. They gave us a great price on the work, were fast, organized, super friendly, professional and finished the job as promised. They came highly recommended by a neighbor and delivered. What a relief to have that done! Thanks to Bob Knight and crew. Great folks all. read more

Bob Knight is a racist and complete nightmare to deal with. Smells like he showered in Coors Light and he clearly feels the same way about deodorant as he does ethnic people. Everything is at or well below average from scheduling and quality of work to completion when dealing with this individual. Do yourself a favor and take your money elsewhere. read more

Knight's installed a dry well for handling my water softener discharge. They were very timely with the install, very efficient, and thorough with everything involved. Very affordable too. I recommend them highly! Rich S. read more

I met Bob through a neighbor that was getting some work done by him. I inquired his opinion on moving a shed on my property. He was extremely informed on what he was doing, and even offered to lend me some large, somewhat expensive PVC pipes to help the process along. I appreciated the time he took to help someone that wasn't necessarily a customer and his generosity to loan out expensive material that would only be used temporarily. Excellent contact to have for any future projects! read more

Required a sewer repair prior to home sale. Called Knight Grading and within minutes spoke with Bob Knight had a quote and repair was scheduled. The work was fast and complete. They made a high stress repair almost painless. Highly recommended. read more

Just plain ol' didn't show up. Left work, Sat and waited for the entire time of the window, and nothing. No phone call, just nothing.

I hired Bob Knight to fix our gravel driveway. Him and the crew showed up promptly on the scheduled day and did an amazing job! Not only are the potholes gone but it is now graded correctly and they added additional parking spaces as instructed. The job was done quickly and the site was clean when they were done. I would definitely hire them again. read more

The residents at the apartment building that I manage in the historic district of Ann Arbor were experiencing low water pressure. Bob Knight returned my call immediately, came and surveyed the property the same day and diagnosed the problem immediately as the water line from the sidewalk to the house needing replacement. He gave a very reasonable price for an expensive job and was on site beginning the work three business days later. He was honest, highly professional and communicated with me throughout every step of the process. He even saved a piece of the pipe to show me the dire shape it was in. I am grateful for his 35 years of experience in the business. I will use him again without reservation. read more

We have a small addition that we are doing for our garage. Most of the contractors we talked to blew us off because it was a small job. Bob and his crew took care of us! read more

We'd bought an old house on a busy Ann Arbor Street (Miller). One of the first things to go wrong was a broken water service pipe from the street to the house. It looked like we would have to get a permit to close the street to get big equipment in and dig a trench to the house, tearing up the sidewalk and a hedge in between. However, Knight's came in with a smaller trencher eliminating the need to close the street. They were able to go under the sidewalk and hedge, put in the new pipe, wait for the city inspector and be finished within a couple of hours. Also, the price was reasonable! Whew! read more

Highly recommended! Prompt response, good team, professional attitude and finished the project one day early. We had a sewer separation at our home in Ann Arbor; deep sewer location - not an easy problem to resolve. Bob was very sensitive to our situation. As a design professional with 40+ years in the construction industry I have sufficient basis for evaluation. My wife was also very pleased with his services and attitude.

Very happy with the work that was recently completed by Bob at Knights Excavating. He was able to make some very sound suggestions to make my barn even better than originally planned. I would recommend Knights for any of your excavating needs. Project completed below budget, on time and within scope (even grew the scope of work to help with some extra stones I had delivered. He not only did my barn site prep but also moved my stones into my driveway at no additional costs.) Great Company! read more

We had a break in our sewer line from the house to the sewer grinder pump, I called Knight's Grading and Excavating and they came out within the hour, knowing that we did not have a working sewer or running water due to the issue. They were friendly, understanding, and had the work completed within a few hours at a very resonable cost. I couldn't have been happier with the service and the the quick response I received, and they did an awesome job at cleaning up the landscaping when they were finished. I would recommend this company to anyone that needs the services they offer!! read more

If you use this company, ask them to be careful. We're not customers, but we live across the street from someone who was, and Knight's damaged our yard while they worked on our neighbor's place. They were nasty about it when we pointed it out, said they would fix it, but never did. read more

Very nice people!We just had our orangeburg replaced by Knights excavating. We called for a price quote, no service charge.Turns out they were the best price. They started right away.We have a new sewer line! They did a great job putting the yard and side walk and road back together.We definatly recomend them! read more

I highly recommend them for any of your excavatiog needs. read more

We had our orangeburg tile removed before the sale of our house and Knights worked out really well for us - they are old school - but, everything was done perfectly and on time even considering our tricky time issue on the sale of our house. Clean up was also really great as well. Would definitely work with them again! read more

I hired Knights to fix our OrangeBurg sewer pipe. He was easy to work with and did a great job with the replacement and seeding of our lawn. Him and his team were great and I would recommend them to anyone. read more

Terrible service. I contracted Knight's to do a video camera inspection of a sewer line for a house under contract. When I booked the appointment, I was assured that the person would be able to record the video inspection (in order to show proof to the home seller for concessions). Upon arrival, the workers said the video recorder was broken. Then the quote came in $2500 higher than the exact same job that they did for the neighbor just one year prior (this is Michigan. We are in a recession!). Finally, they didn't even provide me a quote in writing or email, even after I made a second request in email. Meanwhile, the $200 video camera inspection check was deposited immediately. Avoid this company. read more

Bob and his crew were awesome. We moved into a house in Dexter and at the final walk through before signing, the city of Dexter came to let us know that we had a defunct water line and that they were shutting off the water. The owners did not want to pay for this, but we were able to get them to pay just before signing and secure Bob Knight to do the work. We didn't have water and were a bit panicked and disheartened. Bob came in and saved the day and we are eternally grateful. He was prompt, helpful and professional. Thank you to Knight's Excavating!!! -Jen & Charlie House read more

Knights Excavating just completed a final grade of our home in Ann Arbor. There were prompt and professional. Yard had some tricky grading issues that they solved creatively. Bob was very knowledgeable about all things dirt and price was fair. Highly recommend! read more

Had great experience with this company! They replaced old water pipe that connects with city system. Did it without digging out lawn! I also appreciated how well they cleaned up. Reasonable, very helpful & pleasant staff. Best contractor I've had. read more

We hired Knight's Grading and Excavating to replace our water service line from the street into our basement. We talked to five contractors and Knight's came up with by far the best plan to avoid digging up our front yard landscaping. They submitted a detailed proposal and their price was fair. When excavating for the new line, they found large boulders appearing to be from an old foundation. It took extra time to remove them and the old fill could not be reused. Knight's supplied new fill at no extra charge. Bob and his crew did exactly what they said they would do, completed the job and cleaned up in one day. They also saved our brand new sidewalk and a 30 year old sage plant that was right next to the excavation site. read more

I had a terrible experience with Knight's, which I had a change of heart and was going to remove until I saw my neighbor rated them highly. Here's the thing. We share a driveway and the neighbor hired them. While their work seems OK, the owner treated me and my family terribly. He shouted at his son, at us (his son apologized to us for his father's behavior), he ranted about "Ann Arbor people", he accused me of "going to" say things I never said, and was basically the most unprofessional contractor I have ever seen, with anger management issues. He has a huge chip on his shoulder. Be careful. read more

If you, as a customer, want someone who cares about you and will do what it takes to get the job done right, call on Knight's. My sewer repair presented several challenging complications and yet the crew worked in all ways to satisfy me at every turn. Not only am I impressed, my neighbors are, too. I highly recommend Knight's Grading & Excavating if you have work that requires real knowledge and skill. read more

We had a sewer line break in mid-winter and got quotes from others who clearly didn't want to be digging up the street at that time of year. Knight's quote was reasonable and they started work immediately. The break was right at the city line, nearly twelve feet down under the opposite side of the street from the house. Excavation on day one, city permit, break fixed, city signed off on the work, refilling the hole and repaving the street all on day two. High quality work in nasty conditions, and Bob Knight himself was always responsive and available for consultation. His crew knew their stuff .. no amateurs .. the street was always safe (overnight, the large hole in the road was very well indicated), and heavy equipment was used skillfully and responsibly (lots of young children in the neighborhood). You can only to resurface a street temporarily when it's freezing; Bob and crew were back a few weeks ago to put down the permanent surface. Very happy with this company and would recommend them. read more

I cannot attest to the quality of service done by Knight's Grading & Excavating, as I have never contracted them, but recently they were hired by my neighbors to grade the lawn of their new home. I was outside with my two 10 month old dogs, which each weigh around 45 pounds, while the owner and an employee of Knight's Grading & Excavating were doing the final grade on my neighbors lawn (a yard that my dogs had been allowed to play in all their lives). My dogs ran towards the owner of Knight's Grading & Excavating and into the freshly graded lawn, which caused them to have to re-rake a small portion of it. I will be the first to admit that the behavior of my dogs was unacceptable; however, I did yell at them and return them to my yard, before they had reached the owner, with every intention of keeping them there so as not to disrupt the work going on next door. My complaint with Knight's Grading & Excavating lies in the way that the owner reacted to the situation. I understand that a dog running at you can look threatening, but I feel that that does not justify his response to the situation. Instead of politely asking me, or even impolitely asking, He said to me "keep your d*** dogs off my final grade" and then threatened to harm them if they were to run into his work area again. This resulted in a verbal exchange between the two of us that I feel was an entirely inappropriate interaction between a business owner and the neighbor of his client. I feel that the manner and language used by the owner was inappropriate and insulting. After both of us had cooled down the owner made no attempt at apologizing. It is my personal opinion that if you wish to have your work done in a polite manner that will help keep your interactions with your neighbors as positive as possible you should probably take your business elsewhere. read more
