"It couldn't have gone better. We have been through two previous landscapers who were unreliable expensive and vanished on us. These guys are reliable and did a fabulous job on stage 1 of the new landscaping. We look forward to stage 2 and an ongoing relationshipship. They are helping turn our home into a valuable property and we are very satisfied. Thank you Tyler and Darcy, from Ed and Esther Beck"

"In late fall, I noticed that a piece of a stone wall abutting my driveway had broken off and was drifting into the driveway. Concerned that the wall would fall into the driveway, I contacted Quinn Brothers Masonry. They came out within two days, assessed the situation and gave me an estimate. The work involved taking down both walls, knocking off old mortar on the stones, and removing ivy. After the walls were taken down, protective covering was placed on the exposed dirt, and drainage pipes and gravel were installed. They then rebuilt the walls, using the original stones. While rebuilding the walls, Patrick Quinn advised me that my stone house foundation had been compromised by paint and old mortar. I authorized additional work to restore the foundation. The paint on the stone foundation was removed and the old mortar was taken out. Then, the entire foundation had new mortar installed. I am extremely pleased with the results and will definitely hire them again."

Retaining Wall Installers FAQs, answered by experts

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.

Small retaining walls still require a foundation of some kind, typically a concrete footing. This helps to ensure the wall is structurally sound and prevents the ground from shifting over time, especially during those winter freeze/thaw cycles. The footing helps spread the weight of the wall and the load it carries over a larger area of the ground, thus assisting with stability. This is true of small retaining walls, larger rock garden walls, and the like. 

Poured concrete is often the cheapest material for a retaining wall, costing around $6 to $8 per square foot. Other budget-friendly options include vinyl and landscaping timbers, which range from $10 to $15 per square foot; landscaping timbers are particularly well-suited for DIY projects. Untreated timber and railroad ties are a step up in price, starting at $15 to $25 per square foot. Natural stones can also be a cost-effective choice if you can source them from your own property, but they can be expensive to purchase. High-end materials like steel are typically the most expensive but offer superior durability and aesthetics.

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.

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.
