"Lorenzo did a great job. All his guys were very attentive. Everything was done right on schedule. All the work was perfect. He did a great job installing my foundation, Belgium block driveway and major regrading of the property. I would hire him again in a heart beat."

"I contracted with Paragon Remodeling Group/Safe Trust roofing for the installation of three security/storm doors, replacement of a gable vent and a minor masonry repair. The job was off to a slow start with multiple concerns involving the installation of the doors (life is never perfect and things don't always go as planned). Tom Hemmerle, the owner of this company, was contacted. He came to our home, inspected the job, assessed the situation and offered definitive solutions. He took this small job as seriously as if it were a large construction project and made it clear to us he would have the it completed in a quality fashion and to our satisfaction, and he did so in a cordial and professional manner. The issues at the onset were more than resolved and our expectations were completely met. We are satisfied homeowners and would not hesitate to call on Paragon Remodeling Group/Safe Trust Roofing for future work. We highly recommend this company. Tom Hemmerle definitely has your back!"

"Amazing! Sabino was responsive, quick and is very knowledgeable. He detected and replaced a bad outlet and took the time to check other outlets on the same circuit. He also installed 2 new exterior light fixtures and replaced 4 light switches in the garage with wifi switches. Sabino took the time to check other outlets in other rooms to ensure they are correctly installed. Additional work has now been requested. Not only is he a great electrician, he's a good person. Well worth your time to inquire for your work."

"Roca Construction called me back in 20 minutes and showed  up at my house in less than an hour. We talked about all the problems/projects I had in mind. He gave me ideas and listened my ideas.  We decided to break the job to 2 different  jobs and do the steps and all the cement work first. Roca and his work men showed up at my house next morning around 8 am and started working.All the  workmen are  nice, polite, hard working and easy going. They returned every morning around the same time including Saturday and Sunday to get everything done. Roca has good ideas to solve problems and surprises that come about when you fix nearly 100 year old house he also has an excellent eye for detail. He has knowledge in many areas of building and fixing which is very handy. All the work turned out super and new brick steps look great and they match well with the existing stone front wall. I will be using Roca and his work crew again."

"Joe was a prompt and professional business man.  He started the job first thing in the morning and was finished in the early evening. He laid yellow Belgium blocks around the perimeter of my driveway and across the apron.   The Belgium blocks look absolutely beautiful and Joe's work was perfect.  He is definitely a perfectionist and I am thrilled at how beautiful it looks.   I had a picture in my mind of what I wanted it to look like upon completion and Joe's work met all my expectations.  I highly recommend him for any and all of your cement work and then some.

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.

Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.

Even if you think you know how to build a retaining wall theoretically, doing the actual work is a completely different story. There are lots of nuances in building retaining walls, and the slightest oversight can compromise their integrity. Therefore, we recommend you hire a pro to build, repair, or replace retaining walls.

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.

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.
