I had both exterior wall and attic insulation. It was done over 2 days because I needed attic duct replacement first. Jeff & Carlos were on time, efficient & respectful both visits. The actual job time was fast with good cleanup. April was super explaining & estimating the work to be done. I'm glad to refer this awesome family-owned business to others. read more

April came out and did a very quick assessment and then within days I was able to get the team of two in my attic and insulation blown in. The job took 2 hours and then they were cleaned up and out. read more

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 require having my painters re-do the patches (at my own expense). J & L originally apologized when I told them about the miscommunication and showed them the emails, then they forgot to send me an invoice. A couple months later they re-sent the invoice and when I reminded them about the situation, they claimed 0 responsibility and completely denied any wrong-doing. ( I attached their response email as well) ***** If you feel comfortable working with a company that will throw you under the bus instead of admitting a mistake, then this is the company for you! ***** tl;dr Their contract explicitly states that their patches will be bad and you will need to have them redone, then when I asked about that part of the contract they explicitly told me the patches would not be visible. (refer to images for context) read more

We called J&L for a quote and within a few hours, Terry arrived for measurements and an estimate. Hands down, J&L had the best price compared to other companies. They came a week later, on time, and blew-in insulation into the attic of my 1950s home. Carlos and Joe worked very hard and cleaned up any mess they made before they left. Now as I write this, it is a 95-degree day and I can honestly say that our house is noticeably cooler. I should've done this sooner. read more

April came right out to give us a quote. She was able to schedule us in less than a week. Two guys came out to blow insulation in our south wall. Courteous, quick, cleaned up and done. Our house is much cooler. Thanks guys. You rock read more

They did a great job! The team was very professional, courteous, and did excellent work.

WEST WALL in our home was facing direct sun. Made the rooms very uncomfortable. Older home built in 1960. I checked into the local company in Lakeside and they came out quickly and assessed the situation. We were given a quote and the job was completed within about a week or less. Blown in insulation in the west facing wall. HUGE difference in the rooms on the west facing side. SO happy we spent the $$ to keep our home cool. We will have them come back to finish a room addition in the future. read more

I have done several renovation projects over the years. Keith and his team were among the best I have dealt with. They helped me through a complex case with title 24 against a tight project timeline. Great communication, showed up when they said they would, friendly, and finished quickly. Thanks! read more

Great job! Hired them to do blown in insulation in my walls. Turned out half my walls were insulated already(my fault, i didnt do a very good job of checking) they ended up giving me a discount from the original quote! Honest company, i highly recommend them. read more

Always a good experience with J&L. Used them many years ago on a reconstruction project at home, and just recently on an attic insulation upgrade. Always friendly, easy to work with and competitive. From Terry on the estimate, to Gary & Luis on install. Couldn't be happier! read more

These guys were good! On time, kind, blowing the insulation like pros and they cleaned everything up upon their exit. The price was fair too! Highly recommended! read more

Their estimator, Rob came to my home on Friday, June 26, 2015 at 10:30AM. We are doing a major remodel and I explained to Rob that the insulation job is holding up the HVAC, and electric work. Rob assured me that he would have the bid to me that same late afternoon. Here I am on Monday at 2:15, left 3 messages for Rob, no return calls. Spoke to the office gal at about noon and they don't know where their estimator is and they don't call me back. So I call them back and ask for the owner to call me. I feel like I'm begging for their business. Not the way it should be. Rob called me finally at 2:20 and said he had too many appointments on Friday and couldn't get mine done, but that he has it right in front of him. He said he would have it to me in 1 hour. I asked him why would it take an hour if you have it in front of you? He said well it's not written up yet. So, it's not done yet...................... read more

Very pleased with the work provided by J&L Insulation. Terry came to do the estimate and was very helpful and professional, explaining the situation in our attic and laying out what was needed. They did blown-in insulation into the attic which was previously un-insulated. We immediately noticed a difference in the ability of our house to stay cool and for the A/C to maintain cooler temps. The price was far better than any other company we asked, and the job was done promptly. read more

Are you kidding me?? These guys were beyond patient with me, made a couple mistakes.. came back to fix it and didnt charge me extra.. They had to come on 2 different occasions because the job required it as well. NO complaints.. and job exceeded my expectations. Not only that, I had another contractor screw something up.. and I asked them for some extra insulation.. and they brought it to me so I can fix the screw up my other contractor did! DO NOT GO ANYWHERE FOR YOUR INSULATION NEEDS, TRUST ME.. I"m not the easiest guy to work with .. and I know they gave me a good deal because the next estimate was $500 more! You guys rock! read more

Can't speak to any of the derogatory reviews but our experience was excellent! Here's what was top-notch: -Communication from the outset - all appointments kept -Price was in-line or lower than bidders I wouldn't hire -Patience when it took longer than expected -Care with all the new gadgets I had installed in my attic -Results - A great job well handled! read more

Called J&L for a quote and within 2 hr Terry was at my house he was very nice and explained everything to me, Carlos and Julian from J&L came and they added insulation batts and blown in insulation to my existing old insulated attic, they worked very hard in the heat and did a great job, Carlos showed me the attic when he was done they very clean they placed plastic on my floors and vacuum when they finished the work, will definitely recommend them read more

Here's what I wrote to my sales rep, Terry, upon completion of my 2100SF attic blow-in fiberglass job on July 22, 2019: "The team did a great job today. Jeff and his assistant were very professional, conscientious and polite. It was a pleasure having them do the work, which looks great. Thank you J&L and Terry. An all-around excellent experience working with you." Plus, J&L's price was better than competitive. Here's my rundown: My attic had some insulation, 6-8" with some low and some bare spots. I wanted to take the level to at least the recommended R38 to increase comfort and cut down on costs both summer and winter. J&L inspected on the same day I called, Wednesday before the long 4th of July, 2019 weekend. Terry checked my attic space, measured, and confirmed my choice of chopped blown-in fiberglass was a good one given the conditions in my fairly cramped attic. We would blow in R30 of additional material on top of existing insulation and fill in the low spots. Terry said it would be a day before I got the estimate; I told him to enjoy his weekend and get it to me Monday. The estimate showed up promptly on Monday, July 8. Other contractors I spoke with weren't even close to the price J&L offered. Based on their bids, I had been seriously considering doing the job myself. J&L's very reasonable bid meant I wouldn't have to climb into the attic. We scheduled the installation at a convenient time. Chad called on the Friday before the Monday installation to confirm. Jeff and his assistant showed up promptly as scheduled and did a thorough job. We took a look into the attic together; he was receptive to my remarks concerning a few details and covered all the bases perfectly. Jeff encouraged me to take a good look upon completion, which I did, and coverage was a clearly uniform, and depth of fill was confirmed by rulers that J&L had stapled at regular locations throughout the attic. Clean up was thorough. Wouldn't know they were in my attic at all, but for the cooler temperature in the house this afternoon. Everyone I spoke and worked with at J&L was very pleasant. And did I mention the price? WINNER. read more

I had j & l come in and install new blown-in cellulose in the attic and also blow it into existing exterior walls. Terry came by to provide the estimate and he was able to answer all of my questions throughout the process. The guys that came to do the work were really professional and courteous. This is not a clean process by any means. If you decide to blow your walls, be prepared for lots of dust. These guys covered everything and did the best they could to contain the dust. They just finished the job yesterday, but the difference in the comfort of my home is immediately noticeable. The walls are no longer cold and my heater ran only twice the entire night. Previously it would fire up once or twice and hour on a 40 degree night. I'm looking forward to seeing how my SDG&E bill is affected. As a bonus, noise from the exterior is dramatically less as well. These guys delivered on both service and price and would recommend them to anyone. read more

Added some insulation to exterior walls and attic of our 1950's home. J&L were not only timely and professional but also very reasonably priced. We could not be happier with the results! read more

Joe & Jose came to put in insulation. Although I personally didn't go into the attic to see the job, they were respectful and courteous of our home. They took about 3 hours. read more

Quote Estimator Lady came to house, was friendly and seemed knowledgeable. Stated they use tarps and plastic to keep the insulation removal and install contained, and from dirtying the walls and floors (which is not what actually happened). We wanted our insulation removed because we know we had a rat problem and lots of droppings. Estimator Lady said she didn't think we needed it removed but would quote it anyway. The quote was in-line with one other quote we received; our third quote was a specialty vendor and was $2k more. We choose to move forward with the removal and install of new insulation based on other's reviews of the company. Removal I was immediately put-off by the customer service of the removal team. I answered the door and Guy A asked if he could use the bathroom. Then a second guy asked to use the bathroom. There was no real introduction or discussion of how the job was going to work. I asked Guy A if he would be using tarps to protect the floor, he said they do but he forgot them. I said he could borrow mine. This was irritating because Estimator Lady said they use lots of tarps to protect the floor and walls from the hoses and to keep things clean. Then I asked Guy A about the plastic that goes around the attic entry, he said he's never used it before. Again, this was irritating because Estimator Lady said they put an ET type protector thing around the opening to keep everything clean. Third, Guy A asked if he could borrow our step ladder since he only had an 8 foot ladder, sure. At this point I was concerned the job was not going to go well. Later that day, Guy A asked to borrow our duct tape because he ran out. I called and left a message with the company's answering machine, voicing my concern. I did not get a call back from them regarding these issues. I knew there were rat droppings in the attic, and I am certain Estimator Lady did not warn the workers of this. I could here them gruffing and swearing in frustration in the attic about rat droppings, and how he's going to run out of bags. After the initial issues, I could hear them vacuuming and making progress. It seemed as if they were spending a good amount of time making sure everything was removed properly. Although in the end my husband would give them a B- for effort in the removal. They worked until about 2:30pm and did about ¾ the removal. Guy A said he needed to leave for the dump so they could get there by 4pm.He said they would be by in the morning to finish up and the install guys should take 1-2 hours. Later the Project Manager called and said they will finish the removal on Day 2, then spray the decontamination spray, let that sit over the weekend, then come back for Day 3 to blow-in. I asked, so you can't do it all tomorrow and he said he has two trucks one is already going one way and the other going the other way, then I started to say something, and he cut in...okay thanks bye (in not those words), but I felt cut off and it was weird. I called right back, got a voicemail box, and left a message to call me about Day 3. Project Manager called back and said he was having phone issues, but I still felt like I was being put-off. Install of new insulation Day 3 was a scheduling issue. At 6:50am Project Manager called, asked to confirm they are blowing-in R30 fiberglass, I said yes. This was irritating because I would assume the Project Manager should know what the job entails. Then he asked what time he said he would be there. I said 8, he said unfortunately he won't be able to get here until 11am. He had one job cancel, one job change, now has to do one before me, etc. I said so there is no way you can be here at 8, no. I had to re-arrange my work schedule to be there for the whole day instead of the half day as expected. They arrived about 11:30, set up plastic on floor and hoses, and did a quick look around house for vents and recessed lighting to make sure they insulated around these areas. Took about 2 hours, and they ended up being pretty clean inside, although I did sweep the garage and driveway of insulation when they were gone. My husband hasn't had a chance to crawl up in the attic to check out the install job. Final Thoughts They did an okay job for an expected price. Their customer service could be much better, an introduction when I open the door, and a description of how the process works is important. All materials and supplies should be provided by the contractor, and service should be provided as promised (keeping the house clean and protected). They could have been more detailed in the removal. As far as I can say, the insulation is working, which is expected. I would not recommend them to friends. You never know what you are going to get when you try new contractors despite all the reviews you read. read more

J&L Insulation provided attic and wall insulation for our small-to-medium sized house. The office and on-site personnel were friendly and cooperative. They worked around our schedule which involved other work being completed on our residence. The on-site folks were effecient, quiet (as possible with the blower) and picked up after themselves. Price was not inexpensive but competitive. I would use this group again, and would recommend them to others. read more

J and L insulation is a really good company to go with when considering insulation. I had them remove an attic full of insulation to have an AC unit installed and then I used them to put new blown in insulation in. They showed up on time. Didn't leave a mess and their prices are really good. I would recommend them to anyone who needs insulation. read more

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. read more

J&L insulated the attic of my home recently. They gave an excellent quote, and even adjusted it lower when there were sections of the attic they couldn't get to. They showed up as promised and did a pretty good job of keeping the place clean. read more

At least five contractors gave me a bid for the work that I needed done: about 1000 square feet of insulation under my floors, and one wall between living space and an unfloored crawl space. J&L's estimate was by far the most well-thought-out and understandable, and was a reasonable price compared to the ones that were much higher and much lower. Getting the estimate required two visits, and this was after it came to me that they or I may not have specified the work properly. After the second visit I was certain they and I could be happy with the bid. My work also required removal of insulation that had been improperly installed, and the installation of both blown-in and batt insulation. They got the work done on the schedule promised, and their staff were friendly and professional. The technicians did have to be asked to clean up after themselves more than they had done without asking, but they did that cheerfully and well. That points up how good an idea it is to be present before and during, as well as at the end of a job. read more

I needed to source insulation not commonly available at big box stores for a wine cellar I was building and these guys pulled through. High quality, formaldehyde and dye free fiberglass insulation at a discounted price, available in no time at all. I can't speak for their installation services but I plan to use these guys again to source insulation for a major home remodel I'm currently doing. read more

We are very happy with our new attic insulation. J&L was prompt and professional. We were given good advice about the recommended scope of the project. Their prices were very reasonable. We noticed the difference in comfort right away. We are confident that we will be much more comfortable this coming summer. read more

J&L Insulation insulated both our new home and then our two story new garage. They were an excellent rate, showed up as promised and completed the jobs as promised. They left the property clean. They gave us some good advice on how to achieve our goals and save some money. Very professional. I am in Julian and it can be challenging to get quality contractors to come up and I highly recommend J&L Insulation! read more

This is a follow-up to my review of their estimating and quote appointment, which was excellent. They performed the work this morning and it went quickly and smoothly.

The install techs destroyed my crushed rock parking area with their huge Truck and trailer. They dug huge holes in the rock and dirt burning out their tires trying to get out of an area they should have not entered in the first place. The install and customer service was great and I would have given them 5 starts if they didn't do damage to my driveway parking area. read more
