Finding the Right Insulation Contractor for Your San Diego Property
Proper insulation is critical for making your San Diego home or building more comfortable, energy-efficient, and safe year-round.
In this in-depth blog post, we go over the different types of insulation, average costs, expected energy savings, and tips for hiring the perfect insulation company for your next insulation project.
In fact, according to the EPA’s Energy Star program, adding insulation can improve a home’s overall energy efficiency by 10-15%, leading to hundreds of dollars in annual savings on cooling and heating bills. With proper installation and the right insulation R-values, the upgrade pays for itself within a few years.
The Benefits of Insulation in San Diego’s Climate
San Diego’s climate is mild, with average temperatures ranging from the low 50s in winter up to the mid 70s in summer. But even in this temperate region, proper insulation offers many advantages:
- Temperature Control – Insulation keeps homes cooler in summer and warmer in winter by preventing conditioned air from escaping. This can reduce the need for air conditioning or heating.
- Noise Reduction – Insulation helps block outdoor noise from traffic, neighbors, etc. This allows for quiet and privacy.
- Moisture Control – Insulation resists moisture buildup within walls, which prevents mold, mildew and rotting.
- Fire Safety – Certain insulation types like rock and fiberglass wool provide an extra layer of fire protection.
- Pest Resistance – Insulation deters pests like rodents or insects from nesting in walls and ceilings.
- Savings on Energy Bills – With proper insulation, HVAC systems don’t have to work as hard. This saves homeowners 10-15% on heating and cooling costs.
With the right insulation and contractor, you’ll enjoy ideal comfort and efficiency year-round.
Types of Insulation for San Diego Homes and Buildings
There are several major types of insulation suitable for San Diego’s climate:
Fiberglass Insulation
Fiberglass is one of the most common and affordable insulation types. It’s composed of small glass fibers bonded by resins. Fiberglass works well for walls, attics, floors, and crawl spaces. The pros of fiberglass include:
- Low cost (between $0.40-$0.50 per square foot installed)
- Effective thermal and sound insulation
- Easy installation for contractors
- Non-combustible and fire-resistant
Potential downsides of fiberglass are that it can absorb moisture over time if exposed and may cause skin irritation during handling. Proper installation and protective barriers are recommended.
Cellulose Insulation
Cellulose is made from recycled paper products like newsprint. It comes loose or can be sprayed into walls or attics wet and dries rigid. Cellulose insulates well against heat and noise. Benefits include:
- Low cost (approx. $0.50 per square foot installed)
- Contains borates as fire retardant
- Made from recycled materials
- Can fill small crevices thoroughly when sprayed
The drawbacks of cellulose are potential settling over time and vulnerability to moisture damage. Professional installation is key.
Spray Foam Insulation
Spray foam insulation starts as liquid components that expand and harden to fill cracks, crevices, and spaces. It excels at insulating and sealing. The pros of spray foam include:
- Expands to fill gaps thoroughly
- Prevents moisture buildup and pests
- Excellent insulation against heat and noise
- Durable material once hardened
Spray foam is costlier, running $1.50-$6.00 per square foot installed. It also requires professional installation.
Rigid Foam Insulation
Rigid foam insulation comes in boards of polystyrene, polyisocyanurate, or polyurethane. It’s commonly used to insulate exterior walls, roofs, foundations, and other surfaces. Benefits include:
- High insulation value even in thin sheets
- Blocks moisture from entering building envelope
- Easy to cut and install around pipes, wires, etc.
- Provides structural enhancement to building surfaces
Rigid foams do carry a moderate cost of $0.90-$1.50 per square foot installed. Joints must be sealed carefully during application.
Rockwool Insulation
Rockwool, also known as mineral wool or stone wool, is an insulation material made from volcanic rock and recycled slag. It comes in batts or loose fill and has excellent thermal and sound-insulating properties. Rockwool is non-combustible with a high melting point, making it highly fire-resistant. It resists mold growth and repels rodents and insects.
- Does not absorb moisture
- Repels water
- High performance, even when moisture is present
Rockwool is a bit pricier, averaging $1.00-$1.50 per square foot installed. It requires careful handling during installation to avoid skin irritation.
Wood Fiber Insulation
Wood fiber or cellulose fiber insulation is made from wood chips, recycled paper fibers, or other plant materials. It is available as loose-fill, wet spray, rigid boards, or natural fiber batts. Wood fiber insulation is moisture-resistant and uses natural binders rather than chemicals. It provides great insulation from both temperature and noise.
- Fire-resistant, natural flame retardant
- Sustainable and contributes to the reduction of environmental CO2
- Water repellent
Wood fiber insulation is more expensive than traditional options, averaging $1.50-$2.50 per square foot installed. It requires expert installation to achieve proper density and prevent settling.
Reflective Insulation
Reflective insulation contains sheets of aluminum foil that reflect radiant heat rather than absorbing it. This lightweight material can be used in walls, attics, and crawl spaces. The pros of reflective insulation are:
- Low cost ($0.35-$0.75 per square foot)
- Lightweight and easy to install
- Effective at reducing radiant heat gain/loss
- Can be combined with other insulation types
On its own, reflective insulation has a lower R-value than other types. It also requires a small air gap to function properly.
By weighing the pros and cons of each insulation type, you can select the right material for your specific project. A knowledgeable contractor will make recommendations based on your home layout, climate, and budget.
Average Costs for Insulation in San Diego
According to data from Angi, homeowners pay an average of $1,819 to have insulation installed professionally. However, insulation costs can range widely from as low as $498 up to $4,400 depending on factors like:
- Type of insulation material used
- Location and accessibility of installation areas
- Square footage needing insulation
- Age and condition of your home
- Additional repairs or upgrades performed
Angi also provides some typical price ranges for different insulation materials installed per square foot:
- Fiberglass – $0.30 to $1.50 per square foot

Energy Savings from Insulation in San Diego
In addition to comfort benefits, adding insulation provides significant energy savings in San Diego’s climate. According to the Energy Star program of the EPA, air sealing and increasing insulation in attics, floors, and walls can improve overall energy efficiency by 10-15% in typical U.S. homes.
For the average San Diego home, this can mean annual savings of:
- 10-15% on heating and cooling costs
- 5-10% on total annual energy bills
- Hundreds of dollars saved per year
With proper installation and the right insulation R-values for your home, the upgrade pays for itself within a few years through lower energy bills. Then homeowners continue reaping rewards.
Professional installation also improves the lifespan of insulation. Poor installation often lowers real-world R-values. A certified insulation contractor will ensure your project meets its full potential for energy savings.
Tips for Hiring the Best Insulation Contractor
Finding the right insulation contractor is important to getting the benefits mentioned above. Follow these tips when selecting an insulation pro:
- Verify licenses and certifications – Contractors should have an active license if required by your state or municipality. They should also have manufacturer training and certifications for the products they install.
- Look for extensive experience – Ask prospective contractors how long they’ve been installing different types of insulation. Look for many years of firsthand experience.
- Request references and reviews – Quality contractors should be happy to provide references from past insulation jobs. Look for reviews on Google, Yelp, Angi, and other sites too.
- Get multiple project quotes – To find the best value, get quotes from at least three top-rated local contractors. Compare materials, costs, timelines, and energy claims.
- Discuss optimal materials and R-values – A great contractor will recommend the right insulation types and thicknesses for each part of your home to meet energy codes.
- Consider credentials – Many insulation companies have staff with advanced certifications like BPI or RESNET. These demonstrate in-depth building science expertise.
- Look for proper licenses and insurance – Appropriate liability and workers compensation coverage protects you and is required in most states.
By vetting insulation contractors thoroughly and comparing quotes, you can find the perfect partner for your project.
