Services
Fiberglass Batt Insulation
Fiberglass batt insulation offers an economical solution for thermal and acoustic control in walls and ceilings. Our formaldehyde-free batts ensure energy efficiency and indoor air quality. Installed without gaps or compression, this method suits new construction and retrofit projects, enhancing comfort while meeting R-value requirements.
Cellulose Blown Insulation
Cellulose blown insulation fills enclosed cavities in existing walls, attics, and floors using eco-friendly recycled materials. Our process involves drilling small holes and injecting insulation to achieve desired R-values. This method improves energy efficiency and reduces noise transmission in residential and commercial spaces.
Acoustical Insulation
Acoustical insulation minimizes noise transfer between rooms and floors using unfaced fiberglass or mineral wool batts. Ideal for offices, restrooms, and conference rooms, this service enhances privacy and comfort. We ensure proper installation to maximize sound absorption without compromising structural integrity.
Air Sealing
Air sealing identifies and seals gaps in building envelopes to prevent energy loss and drafts. Combining this with insulation improves HVAC efficiency and indoor air quality. Our technicians use advanced techniques to address leaks in windows, doors, and wall cavities for lasting results.
Radiant Barriers
Radiant barriers reflect heat away from buildings using foil-faced materials installed in attics or walls. This service reduces cooling costs in warm climates by blocking radiant heat transfer. Paired with proper insulation, it enhances year-round energy efficiency for residential and commercial properties.

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

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
