Retaining Wall Construction in Aberdeen
Aberdeen's unique landscape poses significant challenges to homeowners, particularly when it comes to soil erosion. With heavy rainfall and snowfall averaging 35" and 45", respectively, the ground can shift and settle unevenly, leading to slope instability and costly repairs. Building a retaining wall is not only aesthetically pleasing but also a practical solution to prevent further damage.
The median home value in Aberdeen is $225,100, with many homes built in the 1950s. As the foundation of these homes has already begun to set, any additional stress from soil erosion can exacerbate existing problems. A well-designed retaining wall can help mitigate this risk, ensuring that your yard remains level and secure for years to come.
A retaining wall constructed using interlocking block or natural stone can add significant value to a property in Aberdeen. With homes built over 60 years ago still requiring maintenance, it's essential to invest in long-lasting solutions like retaining walls. The cost range of $3,000-$10,000 may seem daunting, but the benefits far outweigh the expense, especially considering the potential for costly repairs down the line.

DIY vs. Call a Pro
Retaining walls under 3 feet tall are manageable DIY projects using interlocking landscape blocks. Excavate a level trench, add compacted gravel base, stack blocks with construction adhesive, and backfill with drainage gravel behind the wall.
Call a professional when:
Hire a professional for walls over 3-4 feet tall (may require engineering and permits), walls supporting structures, walls on steep slopes, or natural stone walls requiring skilled masonry.
