"Ben not only replied immediately to my posting, but gave me a very reasonable quote based on the picture I had sent him of the damaged retaining wall. I suggested he might want to see the actual wall to make sure his price quote would stand, so he came over (on a Sunday!) and immediately said he could repair the wall right then! I am more than thrilled with the beautiful work he did and would hire him again for any type of stone work in the future."

"Apex Landcare is a skilled and friendly company to work with. Kenny and Cam are polite, clean, and knowledgeable about both interior and exterior projects. Their hardscaping work for me has held up beautifully and drains properly. Fall cleanup and tree/yard maintenance is very thorough and well priced. Smaller "honey-do" projects are no problem and the house is always left tidy. I would trust them with larger interior renos as well."

"Carl is enthusiastic, driven and very responsive.  He has a strong vision with creative ideas that are clearly a result of many years in the business...but also has some flexibility.  His crew showed up on time everyday as promised and worked all day long, often until it became dark.  They did a beautiful job.  We would highly recommend Waterscapes to others and will contact Carl regarding future exterior work.

"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."

Customers say: Quick response

"Mr. Dolloff was prompt in his response to our inquiry into landscaping projects we were considering. He gave us a free estimate on several projects. The cost seemed very fair and we had him complete a quarter of the entire project ~ grooming a hillside with severe erosion and creating a parking area for 2 cars. The hillside is beautiful. Exactly what we wanted and better than we expected. The parking area was not what I would call satisfactory. But in all honesty, they completed both jobs on time but unfortunately it was just the day before we got all that heavy rain the weekend of October 21st. We are planning for him to complete the other landscaping we need down and he offered to clean up the parking area as soon as the weather settles down."

"J. came and gave me a fair estimate. He did come back when there was no rain in the forecast and did a nice job filling in my cracks and sealcoating my driveway. I would recommend them. Other vendors I called did not even call me back or show up for an estimate."

Retaining Wall Installers questions, answered by experts

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

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.

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.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.
