Services
Attic Cleaning
Our professional attic cleaning service removes rodent droppings, contaminated insulation, and debris to eliminate health hazards. We perform complete sanitization and disinfection while maintaining strict safety protocols. This essential service improves indoor air quality and prepares attics for insulation upgrades, addressing both immediate contamination and long-term home health.
Insulation Replacement
We install premium R-38 batt insulation to optimize thermal performance and soundproofing. Our experts replace old, ineffective materials with high-quality fiberglass insulation that meets Title 24 building codes. This energy-efficient upgrade maintains consistent indoor temperatures while reducing utility costs by up to 30% through improved thermal resistance.
Rodent Removal
Our comprehensive rodent removal service includes exclusion, sanitization, and proofing. We eliminate existing infestations, repair damage, and install preventive measures to stop future intrusions. The process includes full attic disinfection to remove contaminants, ensuring safe living conditions while protecting property value through permanent exclusion solutions.
Ductwork Replacement
We specialize in complete duct system replacement and repair using high-grade flexible ductwork. Our licensed technicians address leaks, contamination, and inefficiencies that compromise air quality and system performance. New duct installations improve airflow efficiency, reduce energy waste, and eliminate musty odors from mold and debris accumulation in aging systems.
Radiant Barrier
Our radiant barrier installation reflects up to 97% of solar heat transfer in attics, significantly reducing cooling costs. This energy-saving solution works by reflecting radiant heat rather than absorbing it, maintaining cooler attic temperatures that translate to lower indoor cooling demands and improved HVAC efficiency year-round.

I'm very happy with their professional attic insulation and radiant barrier installation work. From estimate to job completion, both the inspector and the crew showed great attention to detail and professionalism. What a tough job for them to use large vacuums to get rid of all the trash from my attic! I recommend them to any homeowners who want to have a clean attic and a more energy-efficient home.

Mark from the Attic doctors told me about this "comfy combo." I was like, okay, lets' do it. He replaced the old insulation with the brand new R-38 Owens Corning and installed the radiant barrier with a "free" gable vent exhaust fan. I was shocked at how good the workers were and how good the change-out worked. This small local company rocks!

Attic radiant barrier installation is the game-changer for my home! Our house in Lake Forest is so hot during summer, and we're tired of paying high electricity bills and running Air Conditioning 24/7. I called the attic doctors for help. Mark came to our house the same day and gave me his honest opinion. No pushy sales techniques at all. He was very straightforward and knowledgeable. We hired his company to replace all the existing super thick 20 years old blown-in insulation with new batt insulation.

The crew of 4 completed the whole project in 7 hours! Impressed by their quick turnaround and quality insualtion&radiant barrier services. It does reduce the heat in the attic quite a bit! Our house is much cooler!

I was looking for an insulation contractor and an HVAC contractor near me in Irvine, and I found the attic doctors. They can take care of both my attic cleanup and ductwork replacement work at once, which is why I chose them. I've always preferred to work with a smaller company where I can communicate directly with the owner. Everything went smooth and they use high-quality insulation and ductwork material. I appreciate their fast, 5 star quality insulation services. I am glad that I can support small business owner in Orange County like Mark.

My son has asthma, so I must be careful where and what I do in the house. Mark from The Attic Doctors told me to clean up all the contaminated blown-in insulation, install new R-38 batt insulation instead and install a Whole House Air Purifier to keep the indoor air clean and without harmful pollutants. It was a good move. The attic cleaner and attic insulation installer were so fast to get the complete attic upgrade project done in less than one day.

I appreciate their professionalism and excellent customer care. After about two months of using the air purifier, I noticed the difference, and I'm glad I moved forward even though it was not a small expense.

I am so glad that I found such a great insulation contractor for my total attic cleanup and insulation reinstallation. I was beyond shocked to see what was up in my attic all these years! Scary! Should've got all the old, contaminated insulation removed a long time ago! The owner Ron and Mark are awesome! Hire them and you will not regret it!

This was a tremendous experience. Ive lived here for 9 years, and Ive never watched a company work so effortlessly achieve a desired result. All three of the workers knew what they were doing: Installing the Condenser in the backyard, putting the furnace and coil in the attic, as well as mounting a new Nest stat in the hall area. This AC upgrade was a gem. The smartest move Ive made in years. I would recommend the Attic Doctors to anyone.

Extremely professional contractors! I am very pleased with the end results for my home. Attic is very clean with new R-38 batt insulation and I appreciate all the hard work these guys have done for us! I notice that our indoor air quality has been better.

I hired The Attic Doctors to redo my attic cleaning and insulation replacement for my home in Placentia. The inspector, Ron, found out that my ductwork was damaged from rodents intrusion. They were very prompt and productive. I didn't want to spend days on any home improvement projects if I didn't have to, and that's why I chose the best insulation contractor to perform the job in a timely manner.

They used super large vacuums to get rid of all the old blown-in insulation and did an excellent job on rodent proofing so that I would never have to deal with rats again! I appreciate their attention to detail and commitment to delivering the best material and service with such a quick turnover time!

This review is overdue as we had Mark out to help with our attic in January, but now that we're in the middle of summer we can 100% say that this was a great investment! Mark was great to work with. Him and his team were able to get our attic cleaned, add radiant barrier and insulation so quickly and efficiently. We're very happy with what they did for us, our house is much cooler!

I called and spoke with Mark on a Tuesday afternoon. I asked him for a quote for a specific type of insulation for me. He then told me that unfortunately they don't do it and he wouldn't recommend it. I asked him why... he gave me advice and that there was another way to go about doing it. I then told him a quote I got from someone else, long story short he gave me excellent advise and even though I wasn't able to use his services this time I guarantee that when I need insulation done he will be the only one I call. He was more than helpful, I felt like I was talking to a friend and being that he is the one who owns the company I know I can trust them. Thank you Mark I really appreciate everything.

I was truly pleased with the attic doctors! Mark came out to our home and was very professional & wore his safety mask gave me a quote for the job we needed in our 1957 home to clean out our attic & and update insulation-with R-38 material & reflective radiant barrier. Also, the team-workers were very professional too! We needed to do this for a long time but wanted to get the best professional men for the job! Next we will need a new air conditioner & heater & will contact Attic Doctors for a quote. Thank for for a job well done!

Attic cleaning, removing old insulation, new insulation, new ducts. Prompt responses, straight forward, easy scheduling, great job. Can already tell new insulation has helped by AC running less. Would recommend to others. Thank you!

My husband and I are glad that we hired The Attic Doctors. Mark was very easy to communicate with and always answered my text and e-mail right away. He and his team removed old insulation and duct, cleaned up the entire attic (970 Sq.ft ) and installed new R38 insulation and R-6 duct. They were punctual and efficient and finished everything within 5 hours. We expected some mess since our insulation was really old, but it was a nice surprise that they didn't create any mess at all. They left our house clean! They are real professionals. We highly recommend them.

Working with The Attic Doctors was the best decision we ever made! Despite the fact that their price was a little higher than another company, we chose to work Marks team. They are not a large company, and I like the attention I got from this professional crew. Took care of my messy and dusty old attic insulation and did a great job on the new insulation installation. Would recommend them to my friends!

Since it has been so hot in Orange County this year, I called the attic doctors to give me an estimate for my attic insulation work. The price was very reasonable and they cleaned up my whole old dirty attic, installed new R-38 batt insulation. My house is cooler and cleaner now. Highly recommend this company to anyone who wants to complete the attic work.
