Services We Offer

  • 100% Satisfied I had a large old rotting and crumbling patio replaced by this company. I had used Tim before to replace an old wall several years ago and knew he did quality work for a fair price. I still got several estimates and they, as before, were priced right for what I wanted done. I really appreciated their punctuality from giving the estimate to starting the job. We had a difficult week with the weather not cooperating but the job was completed in reasonable time. The crew was great and kept me informed at all times.  They did some landscaping around the patio and planted rose bushes. They also fixed my yard and planted grass seed where the equipment had torn up the grass. I have had many compliments from neighbors and family on how great the patio looks. I am 100% satisfied!

  • A New Yard We have a large hill in our back yard with retaining walls and steps. We had Bonomi excavate some of the hill, so we could have more flat yard. They replaced the walls and steps with Unilock blocks. They added mulch and soil to one side of the house to improve drainage.

  • We have had Tim do work for us before. H came out right away to give us an estimate. They are very good about letting you know up front about how long it will be until they will be able to come out and do the work. They came when they said they would. They do a nice job and are pleasant to work with. We had a little issue with the steps. However, he worked with us to make it right. We split the cost of the materials 50/50 with Bonomi. The steps and walls are beautiful. I am anxious for summer to really get the full effect of our new backyard.

  • A Class Act! Tim Walker kept all his time commitments, including the initial site visit and the work. Portions of the 28-foot four-course Belgian block retaining wall, in place for several years, was about to slide down into my driveway--and actually did just after I received the quote. The quote for re-stacking was less than half what a wall with new materials would have cost. Tim explained that a re-stacked wall could not be guaranteed, but I was confident that they would do the kind of job that would keep the wall in business for a long time--so the price should be worth it Tim himself, and a co-worker, appeared on time with all the right machines and equipment, and worked until the job was done. They were extremely courteous, were careful with my driveway and property, and did a great cleanup. A class act!

  • Angie’s List I used Bonomi Landscaping & Tree Service for landscaping last fall. I looked for companies on Angie’s list and Bonomi had good ratings. The guy who came was very nice and I was very happy with the company. The price was on par with what we wanted. Sometimes the owner also came and he was very hands-on. I will definitely use them again. They were good with time and they did not take longer than the time they specified to finish the job. The quality of work is also good.

  • 3 Year Warranty Tim and his company built two Unilock stone walls along my driveway with matching stairs. One wall was terminated by a curve into the hill for a nice effect. I had 4 other contractors bid and Bonomi was the only one who provided a notebook with photographs of their actual work in the area. Also impressive was the 3 year warranty which no other bidder had. One year after the initial work one wall needed a little touch-up and Bonomi very professionally responded to correct at no cost.  For the entire construction time the crew was very professional and courteous.

  • Our Goals and Budget Tim built a small, brick patio and installed a retaining wall with a post column. They also did additional landscaping, planting trees and shrubs. The job took three days. The amount was reasonable for the work. The owner was very flexible in making sure we achieved the goals we wanted. He made up two to three different estimates. We were able to agree on a suitable design within our budget. There was a delay in getting the work done due to the weather; we received a discount for this. Overall, his service and responsiveness was very good. He was very good with responding to emails. He dropped off the brick at our home to make sure we liked the color. The men did not bother us, were pleasant, and did their own thing.

  • Professional and Polite Designed and built a raised stone patio with sitting wall and pillars down to a larger curved stone patio with decorative band. Left the property in good condition including planting grass where grass was disrupted. Very professional and easy to work with. I am very pleased with the work. They worked hard but were enthusiastic and polite.

  • Just What We Hoped For! The folks who came out from Bonomi Landscaping were friendly and very good at their work. They planted both tall and short shrubs and many flowers in our very large backyard. They also put in large accent landscaping stones and a pathway. The end results are wonderful and just what we had hoped for. It is like looking at a whole new yard. Their prices were reasonable for the work done and I will call them back for any other work I need done. I have already referred them to several friends and neighbors.

  • Highly Recommended Tim’s company removed old concrete and put in new Unilock paver walkway and patio in small space. From the estimate to the work, the paver crew was great. Tim showed up for the estimate on time and sent a quote very soon after. They started before the estimated start date and finished before the estimated finish date. All of the crew were polite and courteous. Every day, they left our back yard in a clean state, even when they were in the middle of the project. We were very pleased with the end product and they even took care of some things that I didn't think of that were not included in the original estimate. These guys were all very professional and I would highly recommend Tim and his crew for any projects of this type.
