We all know good insulation can save you hundreds of dollars in heating and cooling costs over a year, but once you’ve determined that you need it, what’s next? Your first thought might be to install it yourself. Maybe you watched a couple of YouTube videos, priced out a few rolls of fiberglass, and figured, “How hard can it be?” We get it—DIY projects can be satisfying. But before you climb into the attic with gloves and goggles, let’s talk about what proper insulation installation really takes.
At Custom Insulation, we’ve spent over 20 years helping homeowners and contractors across Idaho and Eastern Washington get insulation right the first time. So here’s the scoop: sometimes DIY works. Other times, not so much.
The Allures (and Limits) of DIY
DIY insulation has its place, especially if you’re just sealing up a small drafty corner or insulating a shed out back. It can save some money upfront, and there’s a certain pride in doing it yourself. But that’s where the advantages tend to slow down.
Pros of DIY Insulation:
- Lower initial cost (at least on paper)
- Immediate scheduling (you can start whenever you want)
- Personal satisfaction from completing a hands-on project
Cons of DIY Insulation:
- Lack of access to professional-grade materials and tools
- No thermal imaging to detect hidden problem areas
- Higher risk of gaps, compression, or overstuffing, which can reduce effectiveness
- Safety risks—the attendant dangers of crawling around attics and handling hazardous materials
- No warranties or guaranteed performance
Many DIYers don’t realize that improperly installed insulation can actually worsen energy efficiency. If it’s not fitted correctly or if air sealing isn’t done properly beforehand, you’re basically wrapping your home in a patchy sweater. Warm air escapes, cold air gets in, and your utility bills start creeping up.
What the Pros Bring to the Table
Professional insulation requires both hard work and precise knowledge. At Custom Insulation, we don’t just stuff batts in your walls and call it a day. We use thermal imaging technology to identify heat loss and pinpoint exactly where insulation is needed. Whether it’s a brand-new build, a renovation project, or an older home in need of a comfort upgrade, we bring the tools and experience to get the job done right.
Pros of Professional Installation:
- Expert installation tailored to your home’s structure and needs
- Use of cutting-edge tools like thermal cameras and blower door tests
- Access to higher-quality, energy-efficient materials
- Compliance with local building codes and energy standards
- Guaranteed workmanship and warranties for peace of mind
Cons of Professional Installation:
- Higher upfront cost (but with long-term energy savings)
- Need to schedule and coordinate with a crew
But here’s the thing: with a professional, you know the job’s done right. No guesswork. No missed spots. No awkward Saturday afternoons spent sweating in a crawlspace.
The Long Game: Comfort, Efficiency, and Value
When it comes to insulation, what you really want is year-round comfort and lower energy bills. That’s where the real value lies. Professionally installed insulation pays off over time by reducing your heating and cooling costs, improving indoor air quality, and extending the life of your HVAC system. In other words, it’s not just about stuffing walls; it’s about creating a healthier, more comfortable home.
