  • "Very honest and professional company, I called JT and within 2 days he sent their amazing crew to my job site. I am extremely happy with their knowledge and fast response, JT always answers his phone and his customer service is fantastic. Will definitely use them for my future projects!"

  • "OJ Insulation was recommended by our excellent plumber. JT, the estimator, was very professional and easy to work with. The crew arrived as promised and did a very nice job. The second story of our 1930 Spanish home is noticeably cooler after installation of a radiant barrier and R38 batts in the attic. We hope we can get a rebate too. Thanks OJ.

  • "My construction company used OJ Insulation based on a recommendation from a colleague and we couldn't be happier. They scheduled our job within a couple days and the install went perfectly. Their prices are tough to beat and their communication and willingness to work around our ever-changing schedule is what stands out. We've used several insulation companies in the L.A. area over the years and O.J. Insulation will be our company of choice moving forward."

Here are some samples of what our customers are saying about our superior service:

"Over the last year and a half, I have worked with O.J., John & Eddy @ Willows, Hampshire, Mission Lane & now here @ Lugano. Wish I had you all on my other jobs! You are all, definitely my Insulation contractor of choice! Deservingly so, you’ve earned it!"

Robert – Beaumont, CA

"Crew was on time, did a good job. Inspected the house before and after to make sure no damage was done during insulation. Cleaned up after work was completed. Entire job was done in 2 1/2 hours."

Sam – Long Beach, CA

"I had radiant barrier installed. I had to do a little of my own legwork with regard to tax credit and product information. Otherwise the estimator and crew were very professional and the price was very competitive."

– Huntington Beach, CA

"Friendly and on time. Seemed honest and accurate. No problem with sticking to price quote. Job done quickly. They cleaned up pretty well after the job but I had to vaccuum up some leftover dust and dirt. Solid experience overall."

Scott – Sherman Oaks, CA

"Outstanding! A five star rating."

Anthony – Sylmar, CA

"They were on time, efficient and had a great price."

Limer – Long Beach, CA

"I just wanted to tell you, the crew that was sent out did a wondeful job. Oscar and the other two gentlemen arrived on time, worked unbelievably hard in sweltering heat to remove the old blow-in insulation and to install the replacement insulation. They were all very courteous and cleaned up after themselves. Most importantly, there was no damage to my very old, fragile ceiling, which I greatly appreciated. I would certainly recommend your company and the crew you sent to any of my friends, family, and neighbors."

Tracy – Orange, CA

"I would recommend OJ Insulation without thinking twice. They set an example of how business should run. Thank you the great service."

Carol – Los Angeles, CA

"I'm very satisfied with the service and customer care from your staff. I'll refer your company to all of my connections for insulation services. Thank You!"

Steven – Cypress, CA

"The crew was prompt, polite, neat and very fast. Will definitely recommend your company. Not only do we notice less heat from that afternoon sun, but the freeway noise is also less noticeable."

Phyllis – Pasadena, CA

"Your representative is a pleasure to work with. He has always been very thorough and knowledgeable."

Commercial Construction Company – La Jolla, CA

"Very satisfied on all counts. Will use you again and recommend you to others."

Mark – La Habra, CA

"Wanted to reach out and thank you for an excellent job on our home. We had 5 bids for this job which was removal of very degraded over 30 year old cellulose in our attic and installation of R 38 Batt insulation. From the first call with Mark I could tell this was the company for us. He answered questions, was professional and helpful. Todd in scheduling was helpful also and oh my goodness the crews were so hard working. It ha been very hot and the attic is a dirty difficult place to work but they never complained, worked all day, did an excellent job and we feel so much better knowing our attic is as it should be now and we don't have to worry about things up there. thank you to everyone who helped us with our job, we greatly appreciate your expertise and excellence!"

Kim – Chino, CA

"This company is amazing. Very professional and time management is awesome. Not only did the worker (please forgive me I forgot his name) but he walked me through the whole process and did an awesome job even cleaned up the residue afterwards. GREAT COMPANY will definitely be calling and referring them from now on!!! Way to go OJ Insulation from the initial viewing of the area to be worked on, to setting my appointment and to the finished product. Very happy customer!!! "
