We hired South Gate Insulation Pros for an attic upgrade and were very pleased. The team was professional, provided a fair and clear quote, and completed the work efficiently. They did a great job sealing air leaks before adding new insulation. Our home is now much more comfortable, our energy bills are lower, and the house is noticeably quieter. Reliable, quality work from a great local company.

From quote to cleanup, everything was smooth and professional. I wish we had done this sooner!
Next level services worth every penny, thanks to this company.
Outstanding service from a company that truly brightened our home's efficiency. We had an older attic with very little insulation, and the Bright Sky team transformed it. Their quote was clear and competitive, and the installation crew worked efficiently with great attention to detail. They ensured the insulation was evenly distributed and that all vents were clear for proper airflow. The improvement in comfort is immediate—no more drafts and our HVAC system runs much less frequently. Highly recommended.

Our experience with Norwalk Insulation Pros was exceptional from start to finish.

The finished work is neat, even, and exceeds building codes. Our house is noticeably quieter and holds temperature perfectly. It’s clear they take pride in their craft and customer satisfaction.

Living in a historic Compton home meant dealing with high energy bills and uneven temperatures. After careful research, we chose Compton Insulation Pros, and it was the best decision for our home. Their holistic approach—air sealing before insulating—is what sets them apart. Our home is now draft-free, and our HVAC system runs efficiently. The team was punctual, polite, and extremely proficient. I cannot recommend them highly enough.
Exceptional quality from a local business. The office staff was helpful and responsive, and the field crew was phenomenal. They took time to explain the insulation options and helped us choose the best solution for our budget and goals. The installation was flawless, and our home feels like a new, well-sealed envelope. I've already referred them to family. A truly reliable and expert company you can trust.
The level of detail and care this company provides is remarkable. They didn't just add insulation to the attic; they meticulously sealed every wire penetration, plumbing stack, and gap in the top plates first—the critical step that many skip. Our home's ""building envelope"" is now truly sealed. The comfort improvement is immediate and profound. Thank you for your honesty and fantastic workmanship!

The crew arrived on time, worked efficiently in the brutal attic heat, and were incredibly respectful of our home. They installed a deep, even layer of fresh insulation and pointed out several areas where they did extra air sealing. The difference in our home's comfort was immediate, and our next energy bill was significantly lower. Highly recommend this local, reliable company.

They were very easy to work with, they documented all the work. In less than a week I had someone evaluate the work needed and complete. They were also way more affordable than 2 other companies I contacted prior to them.
This company is highly professional. They are punctual, professional, and efficient in their work. They removed old attic insulation, sealed air leaks around vents and lighting, and installed new rodent-proof insulation. The courteous workers handled everything, and our house was very clean when they left. I highly recommend this company.
These guys are so amazing they show up on time. They do a good job and the price was good. I highly recommend them because they are licensed and they use all the professional tools and equipment.
