Can You Spray Foam Yourself? A Guide for Homeowners and Commercial Properties

Spray foam insulation has become a go-to option for both homeowners and commercial property owners due to its excellent ability to seal gaps, improve energy efficiency, and provide long-lasting insulation. While there are DIY kits available, the big question remains: should you take on the task yourself?


The short answer is, you possibly can – but hiring a professional is often cheaper and better in the long run, and here’s why.


DIY Spray Foam: Is It Worth the Risk?

The appeal of doing it yourself is understandable. DIY spray foam insulation kits are available for purchase and may seem like a quick and cost-effective solution. However, there are several factors to consider before deciding if it’s worth it.


Pros of DIY Spray Foam:

1. Upfront Cost Savings: On paper, purchasing a DIY kit appears cheaper. Kits typically range from a few hundred dollars for small areas to over a thousand for larger projects, seemingly less expensive than hiring a contractor.

2. Flexibility: If you have a smaller project or just a single area that needs insulation, you may feel like tackling it in your own time and at your own pace.


Cons of DIY Spray Foam:

1. Costly Mistakes: While the kit itself may be cheaper, mistakes made during application can be expensive to fix. Spray foam expands rapidly and can be difficult to control, especially for those without experience. Over-application can lead to bulging walls or damage to electrical wiring, while under-application may leave gaps, leading to air leaks and reduced insulation performance.

2. Health and Safety Concerns: Spray foam insulation involves the use of chemicals that can be harmful without proper safety equipment and ventilation. If applied incorrectly, it can emit harmful fumes or irritate the skin and eyes.

3. Lower Quality Installation: A professional knows how to apply spray foam evenly and effectively, ensuring complete coverage. In contrast, DIY installations may result in uneven foam distribution or missed areas, reducing the overall effectiveness of your insulation.


Why Hiring a Professional is the Smarter Choice

Although DIY might seem like a way to save money, the long-term benefits of hiring a professional far outweigh the short-term savings, particularly for larger projects like insulating an entire home or commercial property.


1. Superior Efficiency

Professionals have the expertise to ensure that every crevice and hard-to-reach area is properly insulated. When applied correctly, spray foam provides a superior air-tight seal, reducing heat loss and improving energy efficiency. This will reflect on your energy bills, whether you own a home or a commercial building, as effective insulation reduces the need for heating and cooling.


2. Cost-Effectiveness Over Time

While hiring a professional might seem expensive upfront, it’s an investment that can save you significant money down the line. A high-quality installation ensures long-lasting insulation, with fewer repairs or replacements. Moreover, improperly installed insulation can lead to bigger problems such as moisture damage or mould, which can be costly to fix, especially in commercial properties where the stakes are higher.


3. Expertise for Different Property Types

Whether it’s your home or a commercial building, each property comes with its own unique challenges. In commercial properties, insulation might need to accommodate different materials, complex structures, or high-traffic areas. Professionals are trained to handle these variations and know exactly what type of foam, technique, and safety protocols are needed for different environments.


4. Safety and Compliance

In both residential and commercial applications, safety is paramount. Professionals are equipped with the right protective gear, tools, and ventilation systems to apply spray foam safely. In commercial settings, this is even more critical as poor insulation installation could violate building regulations or safety codes, leading to fines or worse. Hiring a professional ensures compliance with all local regulations and building codes.


5. Warranty and Peace of Mind

Most professionals offer warranties on their work, giving you peace of mind that the job will be done correctly. If there’s an issue down the road, it’s typically covered under the warranty, and they’ll make the necessary repairs. In contrast, a DIY job leaves you to cover the cost of any mistakes or future problems.


Spray Foam for Commercial Properties: Why Going Pro Is Essential

While homeowners may be tempted by DIY spray foam kits for smaller projects, commercial property owners should almost always opt for professional installation. Commercial buildings have different insulation requirements due to their size, complexity, and usage. Professional insulation contractors have the experience to handle the demands of larger properties, including:


Building Regulations: Commercial properties are subject to stricter building codes, especially concerning energy efficiency, fire safety, and environmental impact. A professional will ensure your insulation meets all necessary standards.

Custom Solutions: Commercial properties often have unique needs, from insulating large warehouse spaces to office partitions. Professionals can offer tailored solutions that maximise efficiency and performance for your specific building layout.

Minimising Downtime: For businesses, time is money. Professional insulation contractors work quickly and efficiently, minimising the disruption to your business. DIY installations often take longer, which could lead to unnecessary downtime.



While it’s technically possible to spray foam yourself, it’s often far from ideal. The complexities and risks associated with DIY installations, especially for larger homes and commercial properties, mean that the potential savings are usually outweighed by the potential for mistakes, safety hazards, and lower-quality insulation.


Hiring a professional may come with a higher initial cost, but it guarantees a high-quality job that will perform well and last for years. Whether you’re insulating your home or a large commercial building, a pro will ensure you get the best results and long-term savings, making it the smarter choice for most people.
