"This was a complex project with a lot of moving parts.
Several thousand square feet of patio, complicated pool coping and a significant amount of reconstruction. The land I gave Carl to work with was ugly and unstable.
I give Carl an A for time and price because of the value he brings to the table. Not because he's the cheapest or the fastest sprinter.
Some significant challenges materialized over the course of the job that added time and cost to the project. The great thing is Carl rolled with the punches, reacted fast, didn't compromise quality, and never asked for more money.
This was not an easy piece of land to work with. A 40 year old pool patio on shaky foundations.
His foreman/mason Eddie is the only person I trust to do anymore work on my hardscape/landscape. His ability, attention to detail and work ethic is unquestionable.
Carl brings 30 years of experience to the table; great design ideas, flexibility, problem solving, vision..........value!!
Additionally, Carl has a fantastic network of partners that are just as reliable.
I would be happy to provide a reference to all serious buyers.

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

They worked with us when scheduling to have the work completed as soon as possible. I recommend them to everyone."

"Kris and Bob made a master piece for a walkway and stairs using materials we have wanted to display for many years. They were prompt and extremeely curtious of my landscaped areas. Available to answer any questions or concerns regardless of time of day or night. They are both exceptionally creative and go way above and beyond our expectations so much that we would be honored to have them come back to do several other projects for us."

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.

Yes, to build a retaining wall, a permit is required. Similarly, any repairs or modifications to an existing retaining wall require permits. If the planned wall measures higher than 4 feet, most municipalities require designs and permits come through a licensed engineer. In some locations, if the wall is shorter than 4 feet, a permit may not be required. For the requirements in your area, contact your local government.

Rebar is a steel support that goes inside concrete to prevent structural damage over time. Concrete is susceptible to impact, weight, and tension. By inserting rebar into the concrete during the installation, you can help extend its lifespan and avoid hazardous situations where the foundation of your home gives way to tensile forces.

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.

Options include concrete, stone, brick, and wood, tailored for specific design needs.
