Make sure that the insurance premiums are paid up and that the insurance plan includes general liability and workers’ compensation coverage at the very least. You can also contact your local consumer protection agency to find out whether your state of residence has any mandatory bonding requirements for retaining wall building contractors.

  3. What Kind of Work Are You Specialized In?

    Before you build a retaining wall, you have to consider the following factors:

    • The type of soil on your property
    • The intended location and function of the retaining wall

    These factors determine the type of retaining wall that will be best suited for your property, and the type of material that can be used for building it. The most common types of retaining walls are listed below:

    • Gravity Retaining Wall – this type of retaining wall uses its sheer weight and mass to hold back soil or any other materials. It is the most basic type of retaining wall and can be built using a wide variety of materials which include pavers, bricks, unmortared stones, and dry-stacked stones
    • Cantilevered Retaining Wall – These types of retaining walls typically have steel bars run through them, and they are sometimes referred to as reinforced retaining walls. Cantilevered retaining walls are generally attached to a slab foundation in the form of an “L” shape. This slab goes under the soil, and the weight of this soil holds it down, thereby preventing the retaining wall from tipping forward and falling. Additional vertical wings can also be added to the retaining wall’s foundation slab to provide extra strength and rigidity. Cantilevered retaining walls are typically used for commercial buildings
    • Anchored Retaining Wall – this type of retaining wall uses anchors attached to it by cables that are then driven into the earth to support its weight. Anchored retaining walls can be used to provide additional support to the other types of retaining walls
    • Sheet Piling Retaining Wall –this type of retaining wall is typically used in situations where space is an issue, and it basically involves driving a thin wall made from materials like steel, wood, or vinyl directly into the ground. Sheet piling retaining walls can only be used in areas that have soft soil

    Always find out the type of retaining wall that your contractor is specialized in building and make sure that this type of retaining wall will perform the functions you require from it. Even though many professional retaining wall building contractors near you are generally capable of building all types of retaining walls, you should always get confirmation on this from your contractor.

  4. Who Will Do the Work?

    Always make sure that your retaining wall building contractor informs you of the exact number of workers that will be involved in building your retaining wall, including any apprentices or subcontractors. This way, you can ensure that everyone involved in the project is properly licensed, insured, and bonded per the requirements of your state of residence. It is also a good idea to find out from your retaining wall building contractor whether the involvement of any additional workers will have any effect on your bill.

  5. Do You Offer a Warranty?

    A warranty is a guarantee that the provider of a good or service offers to the person that pays for this good or service. Professional retaining wall building contractors near you would typically offer their clients a type of warranty known as a workmanship warranty. The specific name that this warranty is referred to may vary by the contractor, but it usually covers the cost of any building defects in the retaining wall for a specified period.

    Warranties can be offered orally, in writing, and they can also be implied. Regardless of how they are offered, these warranties are usually legally enforceable, therefore, it is always a good idea to request a written copy of any warranty that you are offered. This way, the warranty's terms and conditions, as well as the circumstances under which the warranty can be voided, are stated clearly.

  6. Will This Job Require a Permit?

    One reason why you should always hire a professional contractor when you want to build a retaining wall is that these contractors generally know the permit requirements for different types of projects. A permit is an official government approval that you must obtain before you can carry out a home improvement project that will significantly alter the footprint of your home. Permits are typically required for retaining walls that exceed a particular height, and this height varies by location. For example, in Seattle, Washington, you do not need to obtain a permit to build a retaining wall that will not exceed four feet, while in Branford, Connecticut, no permit is needed as long as the retaining wall is less than three feet.

    In Philadelphia, Pennsylvania, a permit is not required for any retaining wall that is not higher than two feet measured from the lowest level of grade to the top of the wall where no surcharge is supported, as long as the retaining wall does not impound certain types of liquids. In National City, California, a retaining wall building permit will not be required provided that the retaining wall does not exceed three feet, does not have any vehicular loading present, and has a level backfill.

    Note that any professional retaining wall building contractor near you would know the specific permit requirements for your locality. However, you may also contact your city’s building department to confirm this information for yourself.

  7. Will You Provide References?

    You should always ask the retaining wall building contractor that you intend to hire to provide you with references. According to the Federal Trade Commission, any credible contractor should be able to provide you with no less than three references. Contact these individuals and find out what they think about the contractor. If you feel that their opinions may be biased, you can also utilize the services of third-party websites like Better Business Bureau, Yelp, and Google Review to get opinions and reviews of clients near you online on your retaining wall building contractor.

  8. Do You Have a Business License?

    In the United States, any business that has less than 500 employees is considered a small business. Many retaining wall building contractors are either employed by or own businesses that belong to this category. These businesses are typically required to obtain a business license that allows them to operate in a specified area.
