The difference is that in most townships throughout Michigan, the construction of a retaining wall is not regulated by the building department or construction codes. The quality of the construction is solely based on the experience of the contractor or homeowner. In many cases, neither party has extensive knowledge, experience or training, and as a result, it is built with poor integrity, installed, and destined for failure.
If you are considering on hiring a retaining wall contractor, here are some questions I suggest you should ask.
- How many years have you been installing?
- What are the construction specifications that you follow?
- May I have a copy of your construction specifications?
- Are you licensed and insured to be working on my property?
- What is the warranty on the product?
- What is the warranty on the installation/workmanship?
- Where can I see some retaining walls that you have built?
- Do you own the equipment that will be used on my property?
Can I visit your place of business? This question is very important, and I highly recommend you visit the company facility. It is not uncommon for companies to be renting equipment and working out of their home. If a contractor is not fully vested in their company, then I would suggest you not invest in them! These contractors come and go out of business regularly.
