Block Wall Repair & Installation in Tempe
What Are Block Walls?There are several varieties of masonry walls, each of which uses different materials or serves a unique purpose. A qualified masonry contractor can work with multiple masonry materials and construct and repair custom walls and fences to meet his or her clients' unique needs.
In terms of function, the most important distinction to note is between block fences and retaining walls. Both can be constructed from the same materials, but they serve different purposes and require unique engineering considerations. Retaining Walls A traditional retaining wall serves an essential purpose in the landscape: it holds soil in place to create a usable terrace in place of a steep slope. Installing retaining walls allows property owners to improve both the usability and the curb appeal of their lawns and gardens. Block Fences
A block fence serves a different purpose. Block fences are installed above-grade to provide privacy, security, and enhanced aesthetic appeal. In terms of function, they're closer to traditional fencing than retaining walls. |

Block Wall Installation
Block walls can add privacy, security, and curb appeal to any Tempe, Arizona property. Unlike traditional brick walls, decorative concrete block walls are a relatively new invention. Property owners who are considering a new installation can find out what they need to know to make an informed decision below.
Common Materials
Both retaining walls and masonry fences can be constructed using a variety of materials. This variety allows property owners to match their walls to their landscapes or buildings, so it's important to choose the right one. Common materials include:
These days, most Tempe property owners are opting for CMU walls. They're more affordable than brick or natural stone, and in the right hands, they can look just as good.
Bonding Options
Masonry contractors have a few methods for adhering blocks together. Each bond type looks a little different, so property owners sometimes request specific pattern bonds to enhance the aesthetic appeal of their walls.

Bonding Options
Masonry contractors have a few methods for adhering blocks together. Each bond type looks a little different, so property owners sometimes request specific pattern bonds to enhance the aesthetic appeal of their walls.
- Running Bonds - Running bonds feature the simplest pattern and consist exclusively of stretchers. As a result, they're also sometimes referred to as stretcher bonds.
- Header Bonds - Header bonds differ from running bonds in that the shorter face is exposed. A basic header bond features lines of blocks overlapped in the middle to create a zig-zag pattern similar to that associated with running bonds.
- English Bonds - English bonds require laying alternating lines of stretchers and headers. They're more complex to lay than the header or running bonds and require coin closers to break the vertical continuity of the corner blocks. English bonds are great for constructing masonry fences.
- Flemish Bonds - Flemish bonds are similar to English bonds, except that each line is constructed using alternating stretchers and headers. Walls that feature this bonding type offer unique aesthetic appeal, but they're also more difficult to construct.
- Stack Bonds - Stack bonds feature blocks loaded on top of each other with aligned bonds. They're not structural bonds and should not be used for retaining walls. For decorative masonry fences, stack bonds look great on contemporary-styled properties.
- American Common Bonds - Similar to the English bond, the common American bond features alternating lines of headers and stretchers. The difference is that the header courses are only inserted every five to six lines. American bonds require queen closers at the ends of header courses.
Benefits of Building CMU Walls
|
Of all the masonry materials available, CMUs are the most popular in the Southwest. CMUs can be installed like bricks and can feature any number of standard or non-standard bonds. Unlike traditional bricks, CMUs also come in a range of shapes and sizes, but property owners can learn more about those later. For now, let's look at the unique benefits of building CMU walls.
A well-designed concrete block wall is durable, weather-resistant, low-maintenance, sustainable, and beautiful. The ability to manufacture CMUs off-site also makes installation much easier and more cost-efficient, but those are just a few of the advantages associated with concrete block walls. Here are a few others that are worth noting: |
|
- CMUs are larger than traditional bricks, making them easier and more affordable to install.
- Property owners will have tons of options to choose from, including different shapes, sizes, and finishes.
- A CMU wall will be able to bear weight without cracking, making it a perfect solution for not just fencing but also retaining walls.
- Concrete is far more durable than traditional fencing materials like wood, metal, and even vinyl.
- It takes next to no maintenance to keep a concrete block wall looking its best.
- Concrete blocks are able to withstand all kinds of inclement weather, from hurricanes and tornadoes to fire and floods.
- There's no need to worry about insects and other pests, fungus, or mold.
- Concrete blocks out sound much better than traditional fencing materials and can be used to construct a more effective privacy fence even on a busy street.
- When installed by a professional block wall builder, a CMU privacy fence will perfectly complement its surroundings.
- If property owners eventually request block wall demolition, the concrete can be recycled and reused instead of getting sent to the landfill.
Types of Concrete Masonry Units
CMUs come in many different shapes. Most masonry walls feature primarily stretcher units and quoin corner units similar to those used in brick walls. However, there are also plenty of other more decorative options. They include:
- Stretcher-With-Score Units - This type of concrete block is identical in shape and size to traditional stretchers. The difference is, it features scoring that makes it look more like a brick. Stretcher-with-score units offer more decorative appeal, making them popular for retaining walls and fences.
- L-Corner Units - L-corner units provide a viable alternative to quoin corners. Their "L" shape offers a more finished appearance in walls that can be viewed from multiple sides.
- Bullnose Stretcher Units - Bullnose stretcher units are similar in shape and size to traditional stretchers but feature one rounded corner. They're perfect for the ends of multiple-block-thick masonry fences.
- Split Flute Units - Both stretchers and L-corner units can be fabricated in split 6 and split 8 flute varieties. These units feature fluted or scalloped edges, adding an extra element of decorative appeal.
- Split Wide Units - Split wide stretchers and corner units feature decorative patterned sections. The stretchers feature four sections per block, while the corner units feature three sections on one side and two on the other.
The Cost of Installing Masonry Walls
Block wall cost varies substantially from project to project since there are many factors that influence pricing. To give just one example, it typically costs more to install retaining walls than freestanding masonry fences per square foot of wall since it requires more substantial excavation and the installation of drainage solutions.
The average block fence cost is higher than that associated with cheaper, less durable fencing materials like wood, vinyl, and chain link. Factors that can influence the final cost of installing a new wall can include:
The longevity of block fencing helps to offset the initial investment, and most clients will see their property values rise after installing a new masonry fence.
Block Fencing Gates
Privacy and security fences always feature gates. Gate installation can occur either during the initial build or in an existing wall. It's important to hire a gate contractor who has experience working with CMUs, especially if the project involves building arches or other advanced masonry features. The gate installation cost will also vary based on the material used for the gate, the complexity of the stonework surrounding it, and the gate's size.

Block Wall Repair
Brick, CMU, and other forms of masonry are far more durable than traditional fencing materials. Unfortunately, that doesn't mean they'll last forever. Thankfully, a brick wall repair contractor can restore an existing masonry fence or retaining wall to its former glory.

It's always best to address problems with masonry walls as soon as they arise. Putting off block wall repair will only complicate the situation and increase the cost associated with restoring the masonry.
Most property owners can tell when their retaining walls and block fences are on the verge of failure. However, the earlier warning signs can be a little trickier to spot. Look for:
|
A block fence repair contractor can inspect the structure and identify underlying problems that could be causing the masonry to fail. In some cases, improper site preparation and drainage could be to blame. In others, age alone can lead to the deterioration of mortar and blocks. It's only once the contractor has identified the underlying problem that the masonry repair process can begin.
Factors That Lead to Premature Wear
The most common cause behind premature masonry wall failure is improper installation. A wide variety of site conditions can also impact the speed at which mortar and brick, stone, or concrete begin to deteriorate. In Tempe, they may include:
Factors That Lead to Premature Wear
The most common cause behind premature masonry wall failure is improper installation. A wide variety of site conditions can also impact the speed at which mortar and brick, stone, or concrete begin to deteriorate. In Tempe, they may include:
- Nearby Land Use - Masonry walls on properties located close to major roads or rail lines may experience more ground vibration. Over time, the vibration can damage the joints, leaving the wall in need of mortar repair. Nearby excavations can also have an impact on masonry walls in that they can lower the local water table, causing issues with soil quality beneath the walls.
- Nearby Vegetation - Most property owners in Tempe, AZ don't have to worry about local vegetation overtaking their masonry walls. However, introduced species can still become problematic. Ivy and other climbing vines are commonly used in landscaping, but they can penetrate mortar joints, sometimes causing substantial damage.
- Excess Moisture - Excess rain and humidity aren't common problems in Arizona. However, an unusually rainy season can cause problems with masonry walls. It can encourage efflorescence, cause cracks, and, if there is enough rain, even impact soil conditions around the wall. Most moisture problems can be solved by improving the drainage around the site, but damaged masonry may need to be repaired.
What to Expect During the Repair Process
The first step any qualified masonry contractor will take is to thoroughly inspect the structure to identify the extent of the damage and its potential underlying causes. If the wall or fence was properly installed and the deterioration is primarily a result of advanced age or acute damage, it can probably be repaired. If the damage is a result of improper site preparation, shoddy workmanship, or the use of low-quality materials, the wall may need to be replaced.

If they've been paying attention, property owners should already have a basic understanding of what masonry contractors look for during an inspection. They try to find not just signs of damage but also the potential underlying problems that could be to blame.
The length of the inspection will vary based on how large the wall is and the extent of the damage. When it's over, property owners can expect to get the inspector's professional opinion about how to proceed. In most cases, property owners will need to schedule repairs in advance to ensure that the contractors have the time to source CMUs, bricks, or other stones that will match the existing wall. |

When to Repair vs. Replace Block Fences
After a full inspection, a qualified masonry contractor will offer his or her professional opinion about whether it's worth making repairs instead of replacing the section of fence or even the entire wall. If property owners are working with reputable contractors, they should feel confident taking that advice at face value. Here are a few of the factors that contractors take into consideration before making their recommendations:
It is also relevant to note that masonry contractors won't always be able to find blocks that are a perfect match for the existing wall or fence. Age, weathering, and availability of materials can all affect whether the patch will stand out from the existing wall. Those who want a perfect match may need full masonry restoration.
Property owners who aren't sure whether to repair or replace their walls or fences should trust the advice of their contractors. Reputable masonry repair contractors will offer unbiased advice about the best course of action given their clients' unique situations.
The Difference Between Masonry Repairs and Restorations
Masonry repair refers to the process of diagnosing and addressing structural problems such as cracks, missing blocks, or deteriorating mortar. Masonry restoration is a more involved process that can require removing blocks, replacing mortar, and sourcing period-appropriate materials that match historical properties. Full restorations often take longer and cost more than basic repairs.
How to Prepare for Repairs
The most important part of preparing for masonry repairs is to find a qualified contractor. Following the inspection, as described above, the contractor will give the property owner a quote and a timeline for project completion. Financing may be available for qualified buyers. If the property owner chooses to go through with the repairs, a contract will be drawn up, and both parties will sign on the dotted line.
Once property owners have taken that step, they can rest easy knowing their walls are in good hands. All they'll need to do prior to the repair date is clear a space in the driveway for the contractors' vehicles and remove any lawn ornaments, furniture, toys, and other personal property from the work area.

Frequently Asked Questions About Masonry Walls
Anyone interested in installing a new wall or repairing existing masonry will have a chance to ask the contractor questions before agreeing to the service. That said, property owners can also learn from others' experiences. They can find answers to some of the most frequently asked questions about block wall installation and repairs below.
How Much Does It Cost to Install Block Wall Fences?
The average nationwide cost of installing a concrete wall is $10 to $15 per square foot. However, there are too many factors that influence labor and material costs to make generalizations about the price tags associated with any particular job. The only way to get an accurate estimate is to contact a specialized contractor.
How Long Do Block Fences Last?
With proper installation and maintenance, block fences can last a lifetime. It's common to see structures built with CMU units from the middle of the last century that are still in pristine condition. Block fencing is no exception.
Do Property Owners Need Building Permits?
In Tempe, building permits are required for any wall that exceeds six feet in height. All walls are also subject to review by the Development Services Manager. Masonry contractors can help their clients obtain the relevant permits and submit documents for review.
Will the Wall Require Concrete Footings?
Most masonry walls can be built on bases of compacted gravel as long as the soil has been prepared properly prior to the installation. In areas where soil instability may become a problem, contractors may need to install concrete footings prior to building the wall.
Are Block Walls Environmentally Friendly?
There's good news for Tempe property owners who want to do their part for the environment. Block retaining walls and freestanding fences are quite environmentally friendly, even when constructed from man-made CMUs. They're long-lasting, don't pollute the surrounding environment, and can be recycled should a future property owner decide to remove the structure.
Can Gardeners Plant Flowers or Shrubs Near the Walls?
It's fine to plant annual flowers or small shrubs near retaining walls and fences. However, property owners should avoid planting trees or large shrubs with spreading root systems in close proximity to their walls. The roots can disrupt the soil and cause problems over time.
Can an Existing Wall Be Extended?
Experienced contractors should have no problem extending an existing masonry wall. Just keep in mind that height extensions may require a building permit if the wall is already close to six feet tall.
Why Should Property Owners Hire a Masonry Contractor?
It may be tempting to assume that since the blocks come pre-fabricated, installing block fencing is a simple matter. In fact, installing fences and retaining walls takes a good deal of specialized skill, knowledge, and experience.
There may be engineering or site concerns that property owners would overlook, and the average Tempe resident has no knowledge of how to properly mix and apply mortar. The bottom line here is that the only way to wind up with a beautiful, long-lasting fence is to hire a specialist.
What Kind of Maintenance Do Block Fences Require?
The only routine annual maintenance block fencing requires is cleaning. Make sure to use products designed for cleaning concrete and test them on small areas before applying them to the entire fence. Beyond annual cleaning, all concrete walls need is periodic resealing. Experts recommend resealing the walls every few years.
