"Jackie Chow was the initial representative we met and he performed an initial inspection and thoroughly explained all of the different options and costs. There were no pressure tactics. Once we had analyzed the info and notified them that we wanted to proceed, the project was scheduled within 10 days. On the day of installation, Hugo and his crew arrived early and began tenting the work area to the entrance/exit points. They removed the old insulation, cleaned and sanitized the attic, sealed the ducts where necessary and re-installed new R38 batt insulation. When finished, the cleaned up the area and were on their way in about 5 hours. No fuss, no mess. I would definitely recommend Insulation Labs"

"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"This business is great to work with! They showed up early and got right to work. They laid down protective plastic as we have blown insulation that gets everywhere. They installed attic and subfloor. I thought they would be here all day. They were down in about 3 hours. Quality work, professional and very informative and clean!"

"Me and my husband live in a condo in Los Angeles. About 6 months ago the neighbors upstairs rented their condo. The new neighbors are a family with two kids who are very sweet, but like to wake up early and throw stuff on each other. (At least thatâ s what itâ s sounds likeâ ¦) we talked to a few different contractors, most have offered us to inject insulation to the ceiling. We tried it, as it was not expensive, but, this did almost nothing. My husband who has very light sleep kept waking up every day at 5, what made our life very difficult. We did some due diligence and realized we need a much serious approach. When we talked to Eli at ELM, we understood right away thisbis the right contractor for us. His level of knowledge exceeded everyone else's, and he was wiling to make everything as clear as possible for us. The price wasnâ t cheap, as the construction included demo, installation of many materials and even lowering the ceiling. The project took about 2 weeks and we could see the difference right away. We could barely hear any thing!! What a huge difference! The crew were cleaning after every day of work and were very professional. I highly recommend ELM (make sure Eli is meeting youâ ¦.) for every Sound Proofing project. Thank you Eli (and pedro!)"

"It was a pleasure to work with Charlie and the folks from Lancaster. They installed a radiant barrier and R38 fiberglass batt insulation in our attic (which had a little bit of some old insulation in it). They gave us a great bid, and they completed the work quickly and efficiently. They were very respectful while here, and did a great job cleaning up."

"I’m extremely satisfied with their service! We hired them to do the clearing and installing for the new insulation in my attic a few months ago. It was very easy to set up an appointment over the phone. Adam, the owner, was very helpful every step of the way. They worked super fast to help install the insulation and disposed of the previous one. Great job and thank you guys!"

FAQs for batt, rolled or reflective insulation install or upgrade projects in Altadena, CA

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
