The cost of building a retaining wall for residents in Missouri might fall within the national average of $5,372, although the actual price can vary depending on several factors.
Your location will partly determine how much you need to spend on this project. For instance, masonry companies in Kansas City might charge differently from other cities. Most households usually pay between $2,890 and $7,854. Some might even have a budget of up to $13,000 for more massive walls in their landscaped gardens. Beginners should consider hiring a professional for this kind of task, as experts are more capable of knowing the right size for your property.
Common Materials
You could limit your spending by knowing the cost for different types of masonry materials. For instance, poured concrete is one of the most expensive with an average price of $20 per square foot. This is a great choice for those who want a durable and damage-resistant wall, along with a modern design. Cinder block can be an alternative for a lower price worth at least $10 per square foot, although it isn’t as strong as poured concrete.
On the other hand, gabion only costs at least $4 per square foot. However, it could also fetch for up to $40 per square foot depending on the type of filler. Homeowners who live near places with shifting soil, such as in coastal areas, should consider this. Since Missouri is an inland state, it might be better to use other materials.
The Cost of Labor
The hourly rate for contractors would also affect the total cost of building a retaining wall. If you plan to use poured concrete, it might cost you between $60 and $80 per hour on average for the professional work. The average hourly rate usually ranges between $53 and $58.
Take note that labor costs not only refer to installation. You might need to pay extra for the disposal of removed soil or have materials delivered to your house. The complexity of the project is another factor, as it will generally cost more in labor fees if you live in a place with a sloped terrain. A higher wall will also be more expensive, so be sure to know the right height to avoid overspending on materials and other expenses.
Estimating Wall Height
Some types of materials for retaining walls have a recommended height like cinder blocks, while others such as stone usually have a simple formula for its vertical length. Cinder-block walls should not be built beyond four feet.
Anything higher might be unpleasing to the overall landscape design. Stone walls are ideal when built for up to three feet. The caveat though requires you to find the right stones that fit well together. Otherwise, it would look sloppy and unfinished.
Choosing the right contractor for your retaining wall project would spell a huge difference in certain costs. A reliable service provider should be familiar with many kinds of masonry materials and which of these are the most suitable for your home.
