DIY vs. Professional Concrete Sealing: What’s the Difference?

Are you debating whether to tackle concrete sealing on your own or hire a professional? Understanding the key differences between the two options can help you make an informed decision. In this article, we will explore the benefits and drawbacks of DIY concrete sealing versus hiring a professional contractor. Whether you’re looking to save money, ensure a high-quality finish, or simply want to know the best approach for your concrete surfaces, we’ve got you covered.

Benefits of DIY Concrete Sealing


When you choose to seal your concrete surfaces on your own, you can save a significant amount of money compared to hiring a professional. DIY concrete sealing kits are readily available at home improvement stores and are typically more affordable than hiring a contractor.


DIY concrete sealing allows you to work on your own schedule and at your own pace. You won’t have to wait for a professional to come to your property, potentially causing delays in your project timeline. With a DIY approach, you have the flexibility to seal your concrete surfaces whenever it is most convenient for you.

Customization options

When you decide to seal your concrete surfaces yourself, you have the freedom to choose the type of sealer and finish that best suits your preferences. DIY concrete sealing kits come in a variety of formulations and finishes, allowing you to customize the look and protection of your concrete surfaces to meet your specific needs.

Drawbacks of DIY Concrete Sealing

Limited expertise

One of the main drawbacks of opting for a DIY approach to concrete sealing is the limited expertise that most homeowners have in this area. Concrete sealing requires a certain level of knowledge and experience to ensure that the job is done correctly. Without this expertise, there is a risk of making mistakes that could compromise the effectiveness of the sealant.

Risk of improper application

Improper application of concrete sealant is a common issue when attempting to seal concrete surfaces without professional help. This can lead to uneven coverage, missed spots, or over-application, all of which can result in a less effective seal. Additionally, using the wrong type of sealant or applying it in the wrong conditions can also lead to poor results.

Time-consuming process

Sealing concrete surfaces can be a time-consuming process, especially for those who are not familiar with the necessary steps and techniques. From cleaning and preparing the surface to applying multiple coats of sealant and allowing for proper drying time, DIY concrete sealing can eat up a significant amount of time and effort. This can be a hassle for homeowners looking for a quick and easy solution to protect their concrete surfaces.

Advantages of Professional Concrete Sealing

Professional expertise

When it comes to sealing concrete, professionals have the knowledge and experience to ensure the job is done correctly. They understand the specific needs of different types of concrete and can tailor the sealing process accordingly. This expertise results in a longer-lasting and more effective seal.

Quality of materials

Another advantage of hiring a professional for concrete sealing is the quality of materials they use. Professionals have access to high-quality sealants that are not typically available to DIYers. These professional-grade sealants provide better protection against water damage, UV rays, and other elements that can degrade concrete over time.

Guaranteed results

Perhaps the most significant advantage of hiring a professional for concrete sealing is the guaranteed results. Professionals stand by their work and offer warranties or guarantees on the quality of their sealing job. This means that if there are any issues with the sealant or the application process, the professional will come back and fix it at no extra cost to you. This peace of mind is invaluable when it comes to protecting and preserving your concrete surfaces.

Disadvantages of Professional Concrete Sealing

Higher cost

When opting for professional concrete sealing services, one of the main disadvantages is the higher cost associated with hiring professionals. While DIY concrete sealing may require some investment in materials and tools, hiring professionals can significantly increase the overall cost of the project.

Scheduling constraints

Another downside of professional concrete sealing is the scheduling constraints that come with relying on external services. Scheduling an appointment with a professional concrete sealing company may not always align with your timeline, leading to delays in completing the project. This can be particularly frustrating if you have a tight deadline or need the concrete sealed quickly.

Limited customization

Professional concrete sealing services may offer limited customization options compared to DIY projects. When hiring professionals, you may have less control over the specific products used, the sealing techniques applied, and the overall design of the finished result. This lack of customization can be a drawback for those looking to achieve a specific aesthetic or functional outcome with their concrete sealing project.

Factors to Consider When Choosing Between DIY and Professional Concrete Sealing


When deciding between DIY and professional concrete sealing, one of the key factors to consider is your budget. DIY concrete sealing kits are often more cost-effective upfront, as you can purchase the materials and tools needed for a lower price compared to hiring a professional contractor. However, it’s important to weigh the cost of potential mistakes or improper application when opting for the DIY route. Hiring a professional may cost more initially but can save you money in the long run by ensuring the job is done correctly the first time.

Time constraints

Another factor to consider is your time constraints. DIY concrete sealing projects can be time-consuming, especially if you are not familiar with the process. You may need to set aside several hours or even days to properly clean, prepare, and apply the sealer to your concrete surfaces. On the other hand, hiring a professional contractor can save you time and hassle, as they have the experience and tools to complete the job efficiently and effectively.

Project complexity

The complexity of your concrete sealing project is also an important consideration when deciding between DIY and professional sealing. Simple sealing projects, such as applying a basic sealer to a small patio or driveway, may be suitable for a DIY approach. However, if your project involves intricate patterns, multiple surfaces, or specialized sealants, it may be best to hire a professional contractor who has the expertise and equipment to handle the job properly.

In conclusion, when choosing between DIY and professional concrete sealing, consider your budget, time constraints, and the complexity of your project to make an informed decision that will result in a durable and long-lasting seal for your concrete surfaces.


In conclusion, deciding between DIY and professional concrete sealing ultimately comes down to the scale of the project, level of expertise, and desired outcome. While DIY sealing may be a cost-effective option for smaller areas or those with experience in similar projects, professional sealing offers a higher level of precision, durability, and long-term protection. By weighing the pros and cons of each approach and considering your specific needs, you can make an informed decision that will ensure the longevity and aesthetics of your concrete surfaces.
