A new concrete driveway, patio, or walkway is a significant and lasting investment in your home. It enhances curb appeal, improves functionality, and adds to your property’s overall value. The success of this investment, however, depends almost entirely on one crucial decision: the contractor you choose to hire. The quality of the materials and, most importantly, the skill of the installation will determine whether your new concrete is a beautiful, durable surface that lasts for decades or a source of cracks, spalling, and frustration for years to come.
The process of vetting and choosing a contractor can feel overwhelming. A low price can be tempting, but it is often not a reliable indicator of long-term value. To protect your investment, it is essential to ask the right questions. A true professional will not only have confident and transparent answers but will welcome your diligence as a sign of a serious homeowner. Arming yourself with these key questions will empower you to identify a trustworthy, high-quality partner for your project.
#1: Are You Properly Licensed and Insured?
This is the first and most important question you should ask, and the answer is a simple yes or no. In Pennsylvania, any contractor who performs more than a certain amount of home improvement work per year must be registered as a Home Improvement Contractor (HIC). This registration is your first layer of assurance that the business is legitimate and accountable to the state.
Equally critical is the issue of insurance. A professional contractor must carry two types of coverage. The first is general liability insurance, which protects your property from any accidental damage that might occur during the project. The second is workers’ compensation insurance, which is absolutely essential. This coverage protects you, the homeowner, from any financial liability if a worker is injured on your property. If you hire an uninsured contractor and someone gets hurt, you could be held personally responsible for their medical bills. A reputable contractor will be able to provide you with a current certificate of insurance proving they have both of these policies in place. A failure to provide proof of either licensing or insurance is an immediate disqualification.
#2: Can I See a Portfolio and Speak to Recent References?
A confident contractor with a long history of quality work will be proud to show it off. A professional website with a gallery of completed projects is a great starting point, but you should dig deeper. Ask to see a portfolio of work that is similar to the project you are planning, especially if you are considering decorative options like stamped or colored concrete.
Even more valuable than photos are the experiences of past customers. Ask the contractor for a list of recent, local references that you can contact directly. It is important to ask for recent projects, as this will give you the most accurate picture of the quality of their current crews and processes.

When you speak to a reference, go beyond a simple “Were you happy with the work?” Ask specific questions about the experience. Was the crew professional and respectful of their property? Did the project stay on schedule and on budget? How was the communication with the project manager? Was the site left clean at the end of the job? Speaking to a past client is one of the best ways to get an unfiltered look at what it is like to work with a particular company.
#3: Who Will Be Performing the Work?
It is important to understand who will actually be on your property every day performing the work. Some companies operate with their own full-time, in-house crews, while others may rely heavily on a rotating cast of subcontractors for different parts of the job.
There are significant advantages to working with a company that uses its own employees. An in-house crew typically means that every member of the team has been trained to the company’s specific standards of quality and professionalism. There is a higher level of consistency, accountability, and communication within the team.
You should also ask who your primary point of contact will be throughout the project. A professional company will assign a dedicated project manager or foreman to your job. This individual will be responsible for overseeing the work, answering your questions, and ensuring that every aspect of the project is executed according to the plan. Having a single, clear point of contact is essential for a smooth and low-stress construction experience.
#4: How Do You Prepare the Sub-Base?
This is a technical question, but it is one of the most important questions you can ask, as the answer will reveal a great deal about a contractor’s commitment to quality. The concrete slab itself is only as good as the foundation it is poured upon. A poorly prepared sub-base is the number one cause of premature cracking, settling, and failure of a concrete driveway or patio.
The proper preparation of a sub-base is a multi-step process. It begins with the complete excavation of the area, removing all topsoil, clay, and organic matter down to stable, undisturbed ground. The next and most critical step is the installation of a layer of compacted aggregate, which is typically a specific grade of crushed stone. This stone base provides a stable, load-bearing foundation and, just as importantly, ensures proper drainage underneath the slab.
Finally, the sub-base must be meticulously graded with a proper slope to ensure that water will run off the surface of the finished concrete and away from your home’s foundation. A contractor who gives a vague answer to this question or who plans to simply pour concrete on top of the existing dirt is not a professional and should be avoided.
#5: What Concrete Mix and Reinforcement Will You Use?
Not all concrete is the same. The strength of a concrete mix is measured in pounds per square inch, or PSI. A simple sidewalk might only require a 3,000 PSI mix, but a residential driveway that needs to support the weight of vehicles, especially in a climate with freeze-thaw cycles like Pittsburgh’s, should be poured with a stronger, more durable mix of at least 4,000 PSI.
It is also essential that the concrete mix is air-entrained. An air-entraining agent is an additive that creates billions of microscopic air bubbles within the concrete. These tiny bubbles act as relief valves, giving the small amount of water that is absorbed by the concrete a place to expand when it freezes without damaging the internal structure of the slab. This is a critical feature for any exterior concrete in our region.
You should also ask what type of reinforcement will be used within the slab. Reinforcement, which is typically either a steel wire mesh or a grid of steel rebar, does not prevent concrete from cracking, but it provides crucial tensile strength. It holds the concrete tightly together, preventing any cracks that do form from separating, shifting, or heaving.

#6: Will You Handle All Necessary Permits?
For many concrete projects, especially those that involve a new driveway apron that connects to a public street, a permit from your local municipality is required. The process of obtaining this permit ensures that the project will be compliant with all local building codes and safety regulations.
A professional, licensed contractor will always handle this entire permitting process as part of their service. They know the specific requirements of the city of Pittsburgh or the surrounding Allegheny County municipalities, they know how to properly submit the plans, and they will schedule any required inspections.
You should be extremely wary of any contractor who asks you, the homeowner, to pull the permit for the project. This is a massive red flag. It almost always means that the contractor is not properly licensed or insured and is therefore not legally able to pull the permit themselves. It is an attempt to shift the legal responsibility for the project from themselves to you.
#7: What Is Included in Your Itemized Quote?
A legitimate quote for a concrete project should be a detailed, written, and itemized document. You should never accept a simple verbal price or a single, lump-sum number written on the back of a business card.
A professional proposal will break down all of the different costs associated with the project, allowing you to see exactly what you are paying for. It should include line items for the demolition and removal of any old concrete, the cost of the sub-base materials, the cost of the concrete itself, the labor for the installation and finishing, and the fees for permits and inspections.
This level of transparency is essential for several reasons. It allows you to accurately compare quotes from different companies on an apples-to-apples basis. It also protects you from any unexpected or hidden costs showing up on your final bill. The detailed, written quote is the foundation of your contract and your primary protection as a consumer.
#8: How Do You Address Weather Delays?
Concrete work is highly dependent on the weather. A project can be delayed by a sudden downpour of rain, and new concrete should not be poured if the temperature is expected to drop below freezing. Given the famously unpredictable weather in Pittsburgh, it is important to know how a contractor plans to manage these inevitable challenges.
A professional company will have a clear communication policy regarding weather delays. They should proactively contact you if the forecast is going to impact your project’s schedule and provide you with a clear plan for when the work will resume.
You should also ask what steps they take to protect the work if unexpected weather arrives. What is their procedure if it starts to rain on a freshly poured and finished slab? A professional crew will have plastic sheeting on hand to immediately cover the new concrete and protect the surface from being marred by the rain.
#9: What Kind of Warranty Do You Offer on Your Workmanship?
It is important to distinguish between two types of warranties. The first is a material warranty, which may be provided by the concrete supplier. The second, and more important, is the workmanship warranty, which is provided by the contractor who installs the concrete.

A workmanship warranty is the contractor’s promise that they have performed the work correctly and to the highest standards, and it is their guarantee to stand behind that work for a specified period of time. It typically covers major issues that arise from a faulty installation, such as significant cracking or settlement that is caused by an improperly prepared sub-base.
A contractor who is confident in the quality of their materials and their installation techniques will always offer a clear, written warranty on their workmanship. You should ask to see a copy of this warranty and make sure you understand what it covers and for how long. A company that is unwilling to provide a written guarantee for their own work is a company you should not hire.

#10: What Is Your Process for Site Cleanup?
The final sign of a true professional is the respect they show for your home and property. A concrete project, by its nature, can be a messy process. The demolition of old concrete and the operation of heavy equipment can have an impact on your yard and the surrounding areas.
A professional contractor will have a clear plan for site management and cleanup. This includes taking steps to protect your existing landscaping and the areas of your lawn that are adjacent to the work zone. The quote should specify that the contractor is responsible for the complete removal and proper disposal of all of the old concrete and any other construction debris.
At the end of the project, a professional crew will perform a thorough cleanup of the entire work area, leaving your property neat and clean. This final step is a powerful reflection of a company’s pride in their work and their commitment to providing a positive customer experience from start to finish.
Choosing the right concrete contractor is a major decision, and it is the most important factor in the long-term success of your project. By asking these ten critical questions, you can move beyond the surface-level price and gain a much deeper understanding of a company’s professionalism, expertise, and commitment to quality.
