J L.: Joseph and his crew did a fantastic job from start to finish. Our ADU unit was completed beautifully, including two bathrooms, a kitchen, and a complete roof replacement. The craftsmanship is excellent, the team was professional and respectful, and the worksite stayed clean. We're extremely happy with the results and highly recommend them!
Remove The Old. Install The New. Breathe Easier.
Complete attic insulation removal, sanitation, and installation — plus a free AC duct inspection with every job. See the difference in our before & after gallery below.
10 Photos — See The Difference
Every attic we touch goes from dirty and degraded to clean, sanitized, and properly insulated. Here are five real before & after transformations from our projects.
Old yellow fiberglass was compressed and dirty — we removed it, sanitized the attic, and installed fresh blown-in cellulose.

Attic Insulation In Action
See how we remove old insulation, sanitize, and install fresh R-30 or R-40 — plus a free AC duct inspection.
Benefits Of New Attic Insulation
Old insulation doesn't just underperform — it can actively harm your home. Here's what removing the old and installing new insulation does for you.
Lower Energy Bills
Proper attic insulation can reduce heating and cooling costs by up to 20% — paying for itself over time.
More Comfortable Home
Eliminate hot and cold spots. Your AC and heater won't have to work as hard to maintain a steady temperature.
Healthier Indoor Air
Old insulation traps dust, allergens, and contaminants. Removing it improves the air your family breathes.
Pest & Rodent Prevention
Old insulation is a nesting ground for rodents and pests. A clean attic with new materials deters infestations.
Moisture & Mold Control
Old insulation absorbs moisture and grows mold. New insulation with proper ventilation keeps your attic dry.
Increased Home Value
An energy-efficient attic with proper R-value is a selling point that boosts your home's resale value.
R-30 vs R-40 — Which Do You Need?
The R-value measures insulation's resistance to heat flow. Higher R-value means better insulation. We'll help you choose the right level for your home and climate.
R-30 Insulation
Mild & Moderate Climates
R-30
R-Value
R-30 is the recommended minimum for most California attics. It provides excellent thermal resistance for homes in mild to moderate climates, keeping your home comfortable year-round while meeting Title 24 energy code requirements.
Installed Thickness
Approx. 10–12 inches
- Meets California Title 24 minimum for most zones
- Reduces heat transfer by up to 70%
- Ideal for single-story homes in temperate areas
- Blown-in cellulose or fiberglass batt options
- Cost-effective energy upgrade
R-40 Insulation
Hot Summers & Cold Winters
R-40
R-Value
R-40 is a premium insulation level for homes that experience extreme temperature swings. The extra depth provides superior thermal resistance, keeping your home cooler in summer and warmer in winter — and reducing strain on your HVAC system.
Installed Thickness
Approx. 14–16 inches
- Premium thermal protection for extreme climates
- Reduces HVAC wear and extends system life
- Ideal for two-story homes and hot attics
- Maximum energy savings — up to 20% lower bills
- Recommended for homes with AC ductwork in the attic
Not sure which R-value you need? We'll inspect your attic and recommend the right level based on your climate, home size, and energy goals — at no cost.
From Old To New — Step By Step
Free Inspection & Assessment
We inspect your attic, measure existing insulation depth, check for damage, contamination, and moisture issues — then provide a written recommendation.
Old Insulation Removal
We safely remove all old, contaminated, or degraded insulation using HEPA-filtered vacuums — containing dust and debris inside the attic.
Complete Cleanup & Sanitation
The attic floor is swept, vacuumed, and treated with an antimicrobial sanitizer to kill bacteria, mold spores, and neutralize odors.
Air Sealing & Gap Repair
We seal gaps, cracks, and penetrations around pipes, wiring, and recessed lights to prevent air leaks before installing new insulation.
AC Duct Inspection
While the attic is open, we inspect your air-conditioning ductwork for leaks, disconnections, and damage — and re-seal as needed at no extra cost.
New Insulation Installation
We install your chosen R-value (R-30 or R-40) of new blown-in cellulose or fiberglass, evenly distributed to the proper depth and density.
AC Duct Inspection Included
While your attic is open and clear of old insulation, we inspect your air-conditioning ductwork — at no extra charge. Leaky ducts can waste up to 30% of your AC's airflow, meaning your system works harder, costs more, and cools less.
We check every connection, joint, and boot for leaks, disconnections, and damage — and re-seal as needed so your new insulation works hand-in-hand with an efficient HVAC system.
Finance Your Insulation Project
Attic insulation qualifies for PACE financing through Renew Financial — no money down, repaid through your property taxes. Also eligible for financing through Chase, Wells Fargo, and Foundation Finance.
