Here’s how to get solid information
Concrete projects can be very simple or very complex, but no matter the scale and scope, you should choose a concrete contractor who is properly vetted. Before signing any contracts and breaking ground on that new driveway, run through his handy list of important questions to ask any concrete contractor.
Your contractor should be insured so that you don’t end up liable or responsible for any damage that should occur over the course of the project. Insurance requirements vary from state to state, so check with an insurance agent to fully understand what should be included in your contractor’s policy.
Similarly, each state will have its own requirements for contractor licensing. The licensing ensures that your contractor has proper education, training, and required licenses to do the work.
Ask your contractor how long they’ve been working in the concrete industry and if they have taken on similar projects—you don’t want your home to be a first try at something brand new.
It’s important to look at a portfolio of the contractor's past work to ensure that they can complete the job you want them to complete in the way you want—ask to see photos of similar projects. Some contractors may have a website with photos, others may simply collect them on their smartphone or be able to show you on their laptop or tablet.
References are a great way for you to confirm that the contractor’s work was not only up to snuff but that they were responsive, handled roadblocks well, and were overall pleasant to work with.
When it comes to concrete manufacturers, quality can vary. For instance, a less reliable source might sell concrete that’s prone to cracks. Learn where your contractor sources their concrete and do your research to know if it’s a product you want in your home.
Based on the scope of the project, your contractor should be able to give you a sense of how long it will take to complete. Smaller projects, such as driveways, might be completed in a few days, while large projects could take several weeks.
They should also provide you with an estimated start date, which will depend on the other projects they are working on.
Some concrete work requires demolition, which can damage lawns, landscaping, and other outdoor features. Ask about any suspected risk to your home.
Permits can add time to any home project. A local concrete contractor who is familiar with the area should know the kind of permits required and how long it will take to get them.
The contractor you hire might choose to outsource the role of project manager, and it’s important you know who will be working on your home and who you should be communicating with every day in case anything goes wrong. Any established, trusted contractor should be able to answer this question easily.
By asking this question, you should be able to find out if the removal of any existing materials is included in the quote; some projects will require total removal and replacement of existing pavement.
In addition, your contractor should tell you if the cost includes the curing of concrete—many residential concrete contractors do not cure the concrete immediately after it is placed. This is not often a big problem; concrete is very forgiving and sometimes doesn’t show any signs of wear without curing. That said, curing can prevent concrete cracks (crazing) and keep your concrete durable for longer. Ideally, curing will be included in the final price—if the contractor says it isn’t, see how much it would be to add it.
Establishing when payment should be made and how will provide important clarity and help you agree to terms that work for both you and your contractor. You might find some contractors require a deposit while others don’t. You might also be able to work out incremental payments for larger projects.
You should always ask your contractor to provide proof of their payment to the concrete supplier; this is important, as an unpaid concrete producer has the right to put a lien on your property until the payment has been processed.
Reputable contractors will offer warranties on their concrete installations as an added guarantee of their work. Be sure to review the fine print of the warranty; some make the process of qualifying for the warranty very difficult.
Walking or driving on the concrete before it is set could cause it to crack. Have your contractor give you advice as to when the concrete will be secure and able to withstand pressure. Many will tell you to wait at least three—but ideally seven—days before driving on the surface.
