HVAC Ductwork
his is a system of pipes and channels that distributes heated or cooled air from an HVAC unit throughout a building. Made from materials like sheet metal or fiberglass, ductwork is essential for a home's air circulation and temperature control.
Drill and Fill Wall Insulation
This insulation method involves drilling small holes into exterior walls and injecting insulating material, like cellulose or foam, into the cavities. It's an effective way to insulate walls in existing homes without having to remove the drywall.
Attic Cleaning & Decontamination
This process involves the removal of old, contaminated insulation, rodent droppings, and debris from an attic. After cleaning, the area is sanitized to eliminate any remaining bacteria or odors, preparing the space for new insulation or other uses.
Radiant Barrier Insulation Installation
A radiant barrier is a material that reflects heat, typically made of a highly reflective aluminum foil applied to a substrate. When installed in attics, it significantly reduces radiant heat transfer from the sun, helping to keep the home cooler.
Crawl Space Dehumidifier Installation
This involves placing a dehumidifier in a crawl space to control moisture and humidity levels. It helps prevent mold and mildew growth, wood rot, and pest infestations, protecting the home's structure and improving indoor air quality.
Crawl Space Waterproofing
This process involves measures to prevent water from entering a crawl space, such as installing drainage systems, vapor barriers, and sump pumps. It protects the home's foundation from moisture damage and prevents structural problems.

What Our Customers Say
Noemi

Alex K
Trustindex verifies that the original source of the review is Google. Sergey and his team recently installed an attic fan and radiant barrier insulation in our attic, and the experience was outstanding. From my very first conversation with Sergey, I knew he was the right person for the job. He is a highly professional and experienced contractor who truly cares about quality and attention to detail. Not many people are willing to work in an attic at 140 degrees and still take the time to deliver such precise, high-quality work—but Sergey and his crew did exactly that. I honestly can’t thank them enough. These guys are rock stars—the best contractors I’ve ever worked with
Svetlana Nisanova
Trustindex verifies that the original source of the review is Google. Sergey, Haime, and their team just completed the soffit vents installation at our 3-story home in Beverly Hills, and I couldn’t be more impressed. These guys aren’t afraid of tough jobs—in fact, they take on the work that most other companies shy away from. I had about seven different companies come out, and every single one either refused due to the risk or quoted over $20k for the job. When Sergey came for the estimate, he stood out immediately. He was professional, detailed, and truly cared about doing the job right. His team carried out the soffit vent installation with precision and professionalism, all while treating my home with respect. What really gave me peace of mind is that Sergey and his crew are fully licensed and insured—a huge plus when dealing with a project of this scale. If you’re looking for a contractor in Los Angeles with real experience, professionalism, and the courage to take on challenging jobs, Sergey and his team are the best choice.

After we reviewed a few local vendors, we decided to move forward with Sergey and his crew. With Sergey expertise and his team, we were able to complete the project in timely manner and on time. The crew worked efficiently and with great care, ensuring that the installation was completed to the highest standards.

Roman Ignatyev
Trustindex verifies that the original source of the review is Google. I recently had the pleasure of working with Sergey and his team to address a pressing issue in my home – moisture problems in the crawl space. The excessive moisture levels had become a significant concern, not only affecting the overall structure of the house but also impacting our health and comfort. The musty smell and dampness had become unbearable, and I knew I needed to find a reliable solution. That’s when I hired Sergey and his team, and I couldn’t be happier with the outcome. They were professional, fast, and extremely experienced contractors who took care of the problem with ease.
