Should You Rent or Buy a Spray Foam Machine?
When I first looked into insulating my garage, I didn’t realize how big the decision would be: should you rent or buy a spray foam machine? I thought it would be a simple pick grab a rental, finish the job, done. But the deeper I went, the more I realized this decision isn’t just about equipment. It’s about time, cost, skill, and your long-term goals.
Spray foam insulation is rapidly gaining in popularity in Canada, especially with higher energy costs that we are experiencing, coupled with bitter cold winters. Natural Resources Canada estimates that over one-third of the energy used in most homes can be lost through poorly insulated walls and ceilings. That’s a big reason many homeowners and contractors are switching to spray foam, it seals air better than almost anything else.
But, whether to rent or buy the machine for that job? That’s where things get tricky. Let’s walk through it together like I had to, so you can make the right call the first time.
Why More Canadians Are Turning to Spray Foam Insulation
Before we talk about machines, let’s talk about why spray foam insulation is such a big deal in the first place. More and more people across Canada are choosing it because it saves energy, lasts long, and stops drafts better than fiberglass or cellulose.
- It creates an airtight seal that blocks moisture and cold air.
- It helps lower heating and cooling costs by up to 50% annually.
- It prevents mold growth because it doesn’t hold water.
- It adds structural strength to walls and ceilings.
And let’s be honest, our winters aren’t getting any easier. Whether it’s your basement, garage, or attic, a proper spray foam job can seriously change your comfort level. This surge in demand is why many homeowners are wondering if they should start doing their own insulation jobs.
But before you go shopping for tools, we’ve got to look at what it really costs to own the equipment.

Understanding the Cost of Buying a Spray Foam Machine
Let’s break it down: buying a spray foam machine is a serious investment. These aren’t tools you grab off a hardware store shelf. They’re professional-grade systems that come with a bunch of parts and a price tag to match.
Here’s a quick cost breakdown:
- Entry-level spray foam machine: $5,000–$10,000
- Professional-grade rig with heated hoses: $15,000–$35,000
- Spray gun and nozzles: $500–$1,500
- Protective gear + ventilation setup: $300–$1,000
- Maintenance and repairs: Ongoing, expect $500/year minimum
If you’re a contractor doing jobs regularly, this could pay off. But for one-time DIYers? That’s a heavy load to carry.
Also, keep in mind:
- You need space to store the equipment.
- You’ll need to clean and maintain it regularly.
- You need to understand how to operate it safely.
So again, it comes down to your long-term use. If you’re doing one attic, buying might not make sense. If you plan to do five houses? Now we’re talking.

When Renting a Spray Foam Machine Makes More Sense
Now let’s flip the script. Renting might be the smarter choice if you’re only doing one project or trying spray foam for the first time. Should you rent or buy a spray foam machine really depends on how big the job is and how often you plan to do it.
Typical rental spray foam packages include:
- The machine
- Spray gun and tips
- Heated hoses
- Startup guide or basic training
- Safety equipment (sometimes)
Here’s the good part:
- Rental cost: $350–$700 per day (depending on your region)
- You don’t need to maintain or clean it after
- No long-term commitment
- You test the waters before buying anything
A lot of homeowners who just want to insulate a crawl space, rim joist, or garage wall find that renting is just right.
Still, it’s not perfect:
- Availability may be limited during peak seasons.
- You’re on a deadline, most rentals are 24 or 48 hours.
- If something breaks, you might be liable.
But if you just want to do one or two jobs? Renting is way easier on the wallet.

When You Should Consider Buying Instead
Now, if you’re a contractor or you plan to do multiple insulation jobs, buying might actually save you money. You have full control. You work on your own schedule. And you don’t have to worry about equipment availability.
Let’s say you plan to do five homes this year. Each rental might cost you $500/day. That’s $2,500 right there. A low-end rig might cost $6,000, and you could use it again and again. Now it starts to make sense.
Here’s when buying is smart:
- You run an insulation or renovation business.
- You plan to use spray foam multiple times a year.
- You want to expand your service offerings.
- You have staff who can be trained to use the machine.
It’s also easier to get consistent results when you own the same equipment. Every rig feels a little different, so when you know your machine inside and out, you get cleaner jobs and better customer reviews.
Key Questions to Ask Before You Decide to Rent or Buy a Spray Foam Machine
Still unsure what to do? Here are some of the questions to help you decide whether you should rent or buy:
- How many projects do you plan to complete in the next 12 months?
- What’s your budget for equipment vs. rental fees?
- Do you have time to learn how to use and maintain a machine?
- Are you comfortable with DIY tools and safety gear?
- Do you have space to store a full spray rig when not in use?
- Are you doing this as a hobby or planning to make an income from it?
If most of your answers lean toward “one project, limited budget, no storage,” go with a rental.
If your answers lean more like “multiple jobs, future income, comfortable with tools,” buying is worth considering.
Conclusion: Choose What Matches Your Needs
At the end of the day, the answer to whether you should rent or buy a spray foam machine really depends on what you’re trying to achieve. Renting is perfect for small, one-off jobs or trying it out before going all in. Buying makes sense for long-term users, professionals, or ambitious homeowners who see multiple uses down the line.
