When it comes to making your home more energy-efficient, comfortable, and cost-effective, insulation plays a major role. But with so many options out there—and so much conflicting advice—it’s no wonder homeowners have questions. We hear these questions every day. That’s why we’ve created this in-depth guide to answer the most common insulation questions people search for online. Let’s get into it.
1. What types of insulation are available for homes?
Home insulation comes in many forms, and each type has its own pros and cons. The most common options include:
- Fiberglass Batts: Pre-cut panels that fit between studs and joists. Affordable but less effective at sealing air leaks.
- Blown-In Cellulose: Made from recycled paper, this is good for attics but can settle over time.
- Rigid Foam Boards: Provide good thermal resistance but are best for new construction.
- Spray Foam Insulation: Expands to fill every crack and gap, offering unmatched air sealing and energy efficiency.
At Quirozave Spray Foam, we specialize in closed-cell and open-cell spray foam. Homeowners often ask, “Which insulation is best for energy savings?”—and spray foam consistently outperforms traditional types thanks to its high R-value and moisture resistance.
2. Does insulation really lower my energy bill?
Absolutely. Insulation acts like a thermal barrier, keeping heat in during the winter and out during the summer. When installed properly, insulation reduces the workload on your HVAC system, extending its lifespan and lowering your monthly utility costs.
With spray foam insulation, those benefits are amplified. The air-sealing qualities mean fewer drafts and more consistent indoor temperatures. In fact, many of our clients see a noticeable drop in their energy bill within the first 30 days. According to the U.S. Department of Energy, proper insulation can reduce heating and cooling costs by up to 20%.
3. What should I look for in an insulation contractor?
Hiring the right contractor can make or break your insulation project. Here are the top things to look for:
- Licensing and Insurance: Always work with a contractor who is licensed and insured to protect your home and your investment.
- Experience and Expertise: Look for a team that specializes in the type of insulation you need—especially spray foam.
- Transparent Pricing: You should receive a detailed quote that includes materials, labor, and any prep or cleanup work.
- Reputation and Reviews: Check Google, Yelp, and the Better Business Bureau.

4. Can I add spray foam over old insulation?
One of the most common questions we get is whether spray foam can be installed over existing insulation. The short answer: Yes, but it depends.
If your current insulation is dry, free of mold, and not compacted, spray foam can often be applied directly over it to improve performance. However, if there’s any sign of moisture damage, pest infestation, or mold, it’s best to remove the old insulation before spraying.
Our team conducts a thorough inspection before beginning any project to ensure you get the best possible results.
5. Does insulation need maintenance?
Most homeowners are surprised to learn that insulation doesn’t require ongoing maintenance—especially spray foam. Once installed, it stays in place for decades without settling, sagging, or degrading.
That said, we do recommend periodic inspections every few years to check for any signs of:
- Water Damage
- Rodent Activity
- Ventilation Issues
We offer follow-up services for customers who want peace of mind that their insulation is still performing at its best.
6. How long does spray foam insulation last?
Spray foam insulation is known for its longevity. Unlike fiberglass or cellulose that may need replacement after 15–20 years, spray foam can last over 30 years when properly installed. It doesn’t compress, sag, or deteriorate over time, which means you get long-term value from a one-time investment.
7. Is spray foam insulation safe for my family and pets?
Yes. Once cured, spray foam is non-toxic and does not release harmful gases. During installation, we recommend vacating the area for 24 hours to allow the foam to fully cure. After that, it’s perfectly safe—and can even help improve indoor air quality by sealing out pollutants, allergens, and dust.
8. How much does spray foam insulation cost?
Costs vary depending on the size of your home, the type of spray foam used, and whether old insulation needs to be removed. On average, homeowners can expect to pay between $1.00 and $3.00 per square foot for professional spray foam installation.
Keep in mind: while spray foam has a higher upfront cost than fiberglass, the energy savings and durability make it a smarter long-term investment.
