Founded in 1983, J&L Insulation has provided high quality insulation for over 30 years to the greater San Diego area. Specializing in new home construction, room additions, existing homes, residential and commercial remodels and light commercial insulation applications- we pride ourselves in servicing our customers needs with the highest quality standards.

Our employees are skilled and equipped with the most up to date equipment, products and technology in the industry. Our company is a certified Johns Manville Insulation Contractor.
Services
This phase includes constant monitoring and interaction. We keep an eye on budgets to ensure the lowest costs, stay on top of schedules for timely delivery and work closely with the design team to create your vision. The most common sound insulation in commercial construction is unfaced fiberglass batts installed in interior walls and demising walls.
A fiberglass batt is the most economical product to use when insulating a commercial building or insulating a tenant improvement. J & L Insulation offers our customers a Formaldehyde Free Fiberglass product that is unfaced, kraft faced or encapsulated. Our insulation installers take pride in the quality of their application process.
J & L Insulation can insulate enclosed cavity insulation of existing exterior walls, cathedral ceilings, ceilings between floors and interior walls with fiberglass loose fill insulation or cellulose insulation. Our crews would drill holes into the enclosed cavity and fill the cavities with either fiberglass or cellulose to attain the R-value of insulation you require.

J&L was super quick from the beginning when providing an estimate and installed even quicker! My second time doing business with J&L and i wouldn't use anyone else!

I was planning on painting my house so figured it would be good to insulate the walls from the outside before getting them fully painted. After emailing with them I was assured (more like mislead) that the patches done on the exterior walls would be very hard to see and I would be able to just paint them without having to re-patch even though their contract says they just do "rough patches" (email thread image attached). As you can see from the images, the patches were very poorly done and you could easily see the spot where it was patches (raised with a dimple in the middle), which lead me to

This is the second time I have used J&L. They are a great company and everyone that works there is right on top of things. Jeff and Joe came out and got my job done ASAP and it went as smooth as silk. I have already recommended them to others living in my condo complex. I highly recommend them for your insulation needs.

Great company to work with. I had insulation blown in my 2 attics. Estimate process was quick, 2 guys showed up with the truck on time. Everyone was professional. I would definitely use use their services again. Prices are very reasonable too. Before you buy insulation and rent the machine from a local hardware store, check them out. Chances are that you will pay the same or less with them.

I did not work with this company but they were referred to me by a local HVAC company. I called first thing in the morning to speak to someone about cost to remove and install insulation in a residential attic. The woman told me that there was nobody in right now and they were out on appointments but should be back by 3:00. I left my name and number and asked for a call back. Checked back with them at 4:30 and was told everyone was gone for the day. The woman told me that she said I was going to call back. I informed her that was not the case (not that it was that big a deal) but I left her with

J&L did our exterior walls. They showed up on time and completed the work on time. We also just saw them on another job in Pacific Beach doing more great work.

I would give 0 stars if I could. I scheduled work months ago. They failed to show up to the first appointment with less than 24 hours notice. They failed to show up to the second appointment with no notice. Unprofessional, unreliable, and disrespectful of their costumer's time. Its now almost winter and my kids rooms still aren't insulated because of their unreliability.

Consistently the least expensive quote ($1000 cheaper than the local warehouse store) for me and now they have insulated 2 of my homes. I couldn't be happier with their quality and service. Their installers both times were cheerful and professional and both time went the extra mile to do great work. I am always concerned about someone stepping through the drywall or not reaching for the hard to get at a tight spot, but I am really impressed with this company and don't hesitate to recommend them. They used cardboard and plastic to protect my wall corners and furniture from the hose and also to keep
