"

They actually hung some paintings for us because we have like a two-story wall.  We live in a raised ranch, so there?s a big wall that goes from the ground level up to the ceiling of the first floor, along the stairwell, and I wanted a painting hung up at the top of that wall.  And so I called Tom and said well who do you know that can do this and he said well we do that.  I said okay.  So he sent a couple of guys out, not only did they hang the painting, they re-hung paintings that were kind of crooked.  They just took care of hanging things that required going up a ladder, like a two floor ladder, a two-story ladder.  What they did was up a scaffolding and just did it that way, which is not something that a homeowner can do.  I just keep going back to LOPCO for everything.

"Adelino Soares did incredible work on my retaining wall, building a new structure that is sturdy and beautiful. I was so thrilled with his work that I hired him to perform two additional jobs. He just finished replacing my front steps, and we're currently contracted for a backyard patio. On all of his jobs, Mr. Soares was honest, professional, and a joy to work with. He gave straightforward comments and fair estimates, and the quality of his work is difficult to understate. I highly recommend him as a contractor, as a professional, and as an expert stonemason."

"In a word - perfect! This is the biggest project I have had done on my house, and it is hands-down the best contractor experience I have ever had. To start, communication was fantastic. John, the owner, is prompt in replying to calls, emails, and texts. He proactively kept me in the loop with everything that was going on. It took a few months to get a permit from the town, and he gave me status updates weekly up until they were ready to start. At that point the crew, including John's son Jake, were on-site daily for about 4 weeks. I live by the bay, so they took extra steps to prevent mud runoff from the excavation by containing their work with hay barriers and silt fences. It was fun watching the demo, then the wall go up bit-by-bit each day. On inspection day, the town inspector commented that their work was a perfect example and he will document my specific wall as an example of "how to do it right". Talk about peace of mind! Throughout the project, John was supportive of last minute choices of things like paver style/placement, and it was no problem to take apart and remove a stair base that I decided I wanted in a different spot. I need to sum up by saying working with Greenskeeper was an absolute pleasure. I was very well taken care of, got exactly what I wanted, and the results are stunning! They will be back in the spring to seed grass where they worked, and I have already worked with John to plan a large backyard project and side yard project for next year."

Retaining Wall Installers FAQs, answered by experts

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

The lifespan of a retaining wall varies based on its material, installation quality, maintenance, and local climate, with an average range of 20 to 100 years. Retaining walls made from durable materials like concrete, stone, and brick generally last a minimum of 50 years. Concrete walls typically last between 50 and 100 years, while brick can last for over a century in ideal conditions. Timber retaining walls can last from 20 to 40 years, depending on the wood quality, and pressure-treated wood walls average around 30 years. It is important to note that a retaining wall can fail prematurely if it was poorly constructed, for example, with inefficient footings or without necessary rebar reinforcements.

There are contractors specifically trained in the design and construction of retaining walls. Retaining wall contractors are skilled at dealing with the soil on your property and assessing what kind of drainage should be installed. They will recommend the best materials to use for the project and can handle the processing of permits by local authorities.

While vinyl is the least costly material for building a retaining wall, the most cost-effective method is to use wood or concrete blocks for a DIY retaining wall under 2 feet tall. Wood is inexpensive but lasts 20 years or more with care. Concrete can cost a little more but is stronger and will last longer with less maintenance.

Regular inspection for issues like cracks or leaning and ensuring drainage stays clear.
