The attic is the first place you should look when it comes to maximizing energy efficiency and saving money with insulation. Insulating your attic (including knee walls) is one of the easiest ways to make your home more energy-efficient.
As you probably know, hot air rises, making attics one of the biggest sources of heat loss in your home.

What’s the Best Insulation for California Attics?

Our southern California home insulation experts typically recommend radiant barrier insulation for attics. Radiant barrier insulation (or foil insulation) is a good option for attics because it increases your home’s ability to reflect, rather than absorb, the sun’s energy. The most cost-effective option would be to combine a radiant barrier with blown insulation.

However, there is no “right” type of attic insulation. We install a variety of insulation in attics:
  • Fiberglass insulation effectively stops heat transfer into a colder area (heat leaking out of your warm house into the cold winter air).
  • Cellulose insulation has similar qualities to fiberglass and is great for re-insulating all areas in your home, including the attic.
  • Radiant barrier insulation, as mentioned, helps your home reflect heat from the sun, keeping your home significantly cooler.
  • Spray foam insulation is extremely energy-efficient because of its high R-value and is great for insulating hard-to-reach places because of the liquid spray application.

Great company. I called them to fix or replace our attic vent that was not working since we moved in. It was easy to get an appointment. I got an appointment 2 or 3 weeks in advance because of my availability. I called them to confirm the morning of the appointment and they were set to go as agreed.
Roosevelt Gause
Resident of LA
Prompt, knowledgeable, and reasonable pricing. Provided four professional employees to complete: removal of old attic insulation, install new attic wall insulation, blow in fiberglass insulation between the floor boards, and blow in an over layer to achieve R49. Accomplished this work on a Saturday morning, in a little under 3 hrs. Awesome service.

Frequently Asked Questions​

Attic cleaning in the USA offers several benefits, ranging from improving indoor air quality to enhancing energy efficiency and preventing potential health hazards. Here are some key advantages:

  1. Improved Indoor Air Quality: Over time, attics can accumulate dust, dirt, pollen, and other allergens. These particles can circulate throughout your home, leading to respiratory issues and allergies. By cleaning your attic, you remove these contaminants, resulting in cleaner and healthier indoor air.

  2. Mold and Mildew Prevention: Attics are susceptible to moisture buildup, which creates an ideal environment for mold and mildew growth. These fungi can release spores that worsen respiratory conditions and cause allergic reactions. Cleaning the attic helps identify and address any moisture issues, reducing the risk of mold and mildew development.

  3. Energy Efficiency: Insulation plays a crucial role in maintaining energy efficiency in your home. Over time, insulation in the attic can become dirty, damaged, or compressed, reducing its effectiveness. By cleaning the attic, you can inspect the insulation, remove debris, and improve its performance, leading to better energy efficiency and lower utility bills.

  4. Pest Control: Attics often attract pests such as rodents, insects, and birds. These pests can damage insulation, wiring, and other structures, creating potential safety hazards. Cleaning the attic allows for pest detection and prevention measures, ensuring your home remains free from unwanted critters.

  5. Identification of Structural Issues: During the cleaning process, you may discover structural problems in your attic, such as leaks, damaged roof decking, or compromised supports. Identifying these issues early on enables you to address them promptly, preventing further damage and potential costly repairs down the line.

  6. Increased Storage Space: Attics are commonly used for storage, but clutter can quickly accumulate, making it difficult to locate items or use the space efficiently. Cleaning the attic allows you to organize and declutter, creating more usable storage space and making it easier to find and access your belongings.

  7. Home Value and Resale: A clean and well-maintained attic adds value to your home. When it comes to selling your property, a clean attic can impress potential buyers, as it demonstrates your commitment to home maintenance and care. It may also help streamline the inspection process and increase the likelihood of a successful sale.

Remember, attic cleaning can be a challenging and potentially hazardous task, especially if you encounter asbestos, mold, or other dangerous substances. It’s advisable to consult professionals or experienced contractors who can ensure a safe and thorough cleaning process.

A crawl space, on the other hand, is a shallow and unfinished area located beneath the main level of a house. It is typically a narrow space with limited headroom, just enough for a person to crawl or crouch. Crawl spaces are commonly found in homes built without a full basement or on sloped terrain. They provide access to utilities, plumbing, electrical systems, and sometimes offer limited storage space.

Crawl space cleaning refers to the process of cleaning and maintaining the area underneath a house that is accessible by crawling or crouching. Here are the benefits of crawl space cleaning:

  1. Moisture Control: Crawl spaces are prone to moisture issues, which can lead to mold, mildew, and rot. By cleaning the crawl space, you can identify and address sources of moisture, such as leaks or inadequate drainage. Proper moisture control helps prevent the growth of mold and mildew, which can improve indoor air quality and protect the structural integrity of the home.

  2. Pest Prevention: Crawl spaces often attract pests such as rodents, insects, and termites. Cleaning the crawl space involves removing debris and sealing entry points that pests may use to enter your home. This helps prevent infestations and reduces the risk of damage to the structure and insulation.

  3. Improved Indoor Air Quality: Crawl spaces can accumulate dust, debris, and allergens. Cleaning the crawl space helps remove these contaminants, reducing the potential for them to enter your living spaces and improving indoor air quality.

  4. Energy Efficiency: Proper insulation and sealing in the crawl space contribute to energy efficiency in your home. Cleaning the crawl space allows for the inspection and repair of insulation, sealing air leaks, and ensuring proper ventilation. This helps reduce energy loss and can lead to lower heating and cooling costs.

  5. Structural Integrity: Regular cleaning and maintenance of the crawl space enable early detection of structural issues such as foundation cracks, wood rot, or sagging beams. By addressing these issues promptly, you can prevent further damage to the structure and ensure the long-term stability of your home.

  6. Odor Control: Neglected crawl spaces can emit unpleasant odors due to stagnant air, moisture, or decaying organic matter. Cleaning the crawl space, removing debris, and addressing moisture issues can help eliminate or reduce these odors, improving the overall indoor environment.

  7. Increased Property Value: A clean and well-maintained crawl space reflects positively on the overall condition of your home. When selling the property, a clean crawl space can enhance its appeal to potential buyers, potentially increasing its value and facilitating a smoother transaction.

Remember, crawl space cleaning can be a challenging task, and it’s often recommended to consult professionals or experienced contractors who specialize in crawl space cleaning and maintenance. They can ensure a thorough cleaning process and address any specific issues or concerns related to your crawl space.

Rodent proofing in home attics involves specific measures to prevent rodents from entering and infesting the attic space. Here are some steps commonly taken for rodent proofing in attics:

  1. Inspect for Entry Points: Carefully inspect the attic for potential entry points that rodents can use to enter, such as gaps, holes, cracks, or openings in the walls, roof, eaves, vents, or around utility penetrations. Look for signs of gnawing or chewing, as rodents can create their own entry points. Take note of any areas that require sealing.

  2. Seal Entry Points: Use appropriate materials to seal identified entry points in the attic. Use caulk, expanding foam, or other suitable sealants to fill gaps and cracks. For larger openings, use wire mesh or hardware cloth to cover the area and secure it tightly in place. Pay close attention to areas where different building materials meet, as they can be vulnerable points of entry.

  3. Insulate Pipes and Wires: Rodents can use utility pipes and wires as pathways to enter the attic. Insulate these elements using pipe insulation or wire guards to create a physical barrier and prevent rodent access.

  4. Seal Attic Vents: Ensure that attic vents have proper covers or screens in place to prevent rodents from entering. Use mesh or hardware cloth with small openings that rodents cannot squeeze through, while still allowing for proper ventilation.

  5. Trim Tree Branches: Trim back any tree branches or vegetation near the roof or attic openings. Overhanging branches can provide rodents with easy access to the attic. By keeping the branches away from the house, you eliminate a potential pathway for rodents to enter.

  6. Maintain Proper Storage: If you use the attic for storage, store items in sealed, rodent-proof containers or elevate them on shelves to prevent rodents from reaching them. Avoid storing items directly on the floor, as it can provide hiding places for rodents.

  7. Professional Pest Control: In cases of severe infestation or persistent rodent problems, it may be necessary to consult a professional pest control service. They can provide expert advice, identify any overlooked entry points, and implement more advanced rodent proofing techniques specific to your attic.

Remember, rodent proofing in attics is an ongoing process, as rodents can find new entry points or overcome existing barriers. Regular inspections and maintenance are important to ensure the effectiveness of rodent proofing measures in keeping the attic space rodent-free.

Air duct repair is necessary for several reasons. Here are some of the key reasons why air duct repair may be needed:

  1. Air Leakage: Over time, air ducts can develop leaks or gaps due to aging, poor installation, or damage. Air leakage can result in significant energy loss as conditioned air escapes through the leaks instead of reaching its intended destination. Repairing air duct leaks helps improve the efficiency of the HVAC system, reduces energy waste, and lowers utility bills.

  2. Inadequate Airflow: Damaged or poorly designed air ducts can restrict or obstruct the airflow, leading to uneven heating or cooling throughout the building. Repairing or modifying the air duct system can ensure proper airflow distribution, improving comfort and temperature control in all areas of the space.

  3. Poor Indoor Air Quality: Air ducts can accumulate dust, debris, allergens, and other contaminants over time. If not properly maintained or repaired, these particles can be circulated into the living spaces, contributing to poor indoor air quality. Repairing and cleaning the air ducts helps remove accumulated pollutants, ensuring cleaner and healthier indoor air.

  4. Mold or Mildew Growth: Moisture issues within the air duct system can promote the growth of mold or mildew. If left unaddressed, mold spores can spread through the ducts and into the living spaces, potentially causing respiratory problems and other health issues. Repairing and addressing moisture sources in the air ducts helps prevent mold and mildew growth, ensuring a healthier living environment.

  5. Pest Infestations: Damaged or poorly sealed air ducts can provide an entry point for pests such as rodents, insects, or birds. These pests can cause damage to the ductwork, leave behind droppings, and introduce allergens or pathogens into the airflow. Repairing and sealing the air ducts helps prevent pest entry and maintain a hygienic and pest-free HVAC system.

  6. System Efficiency and Longevity: Air duct repair and maintenance contribute to the overall efficiency and lifespan of the HVAC system. By ensuring proper airflow, reducing energy loss, and addressing any issues promptly, repaired air ducts help the HVAC system operate more efficiently, reduce strain on the equipment, and potentially extend its lifespan.

It’s important to note that air duct repair can be a complex task and is best carried out by trained professionals. They have the expertise and tools to identify and address specific issues within the air duct system, ensuring proper repairs and optimal performance of the HVAC system.
