Each step along the way we felt well communicated with and valued as a customer. Competitive pricing and overall all a great value. We had planned on doing a west facing wall but after showing Dave around at our problem areas and weighing the return on investment we decided on the attic. The first team removed all the old insulation with a giant vacuum, the took about 5 hours, the next team came the following day and sprayed in the new foam. There was one little issue that caused damage to the ceiling. They handled the issue like a professional company. They quickly let us know about the issue and had a repair scheduled the same day. Look at the pictures they did a great job!

This company seems to have communication issues? I had the salesman make an appointment at his…read moreinitial visit. He called the office and they gave me an install date. A few days later the same lady called and wanted to make an appointment date? Then, they were going to come the Friday before to install a cover on an attic fan we have. They called Thursday to install an attic stairs? I told them it was only an enclosure. She said it was not needed to come then, they would do it during the insulation install? A half hour later they called back and wanted to come anyway to make the enclosure. She told me she would call in the morning with the time of arrival. At 8:30 my doorbell was ringing, they were already here? Never got a call? The guys arrived in unmarked car and pickup truck (looked like their own vehicles?) It was raining hard so I let them use my garage to cut their materials but they had to go to the local big box store to get them! They did a good job and left. The guy even made a cover for me to cover the fan in the winter months but left it off as the sealant was still wet, he did not want to get cover stuck. On install day I finally got a text saying they were on their way at 8:45am. A marked truck showed up this time pulling a trailer. He said another crew was also on the way. He said they would go up and start the air sealing (I was not getting air sealing?) and install the baffles. He had to call the shop to find out there was no air sealing! They went up to install baffles and I told him about the cover the guy left off. After a bit they came down and said they were done, just waiting on the other crew? I went up the ladder to see the work they had done, they got the baffles up but glued on the cover to the enclosure! I told him the cover was supposed to be removable, he said he would remove it and clean off the glue. Once the guys showed up with the insulation blower it only took a few moments before their machine broke down. They attempted to fix it with no luck. They finally left and came back with a rental from a big box store? They tried again, the stuff was moving slow but it was now at least moving. That did not last long! It finally quit blowing altogether and another guy brought some other insulation. That did not work either, so they went back to the store and got another unit. It finally worked. When they were done I went in to get a check to pay them. When I came out the guy had the ladder up to the attic already closed and was cleaning up. It was now 5:30 pm and I was leaving early the next morning to be gone for 5 days. I never got a chance to check out the final job? Everyone was tired so I thought It would be fine, I'd look when I got home? Once home the following Sunday I did not get to look, Monday was a blizzard outside, Tuesday I had appointments and had out of town visitors arriving. I finally looked the the job on Wednesday. Boy was I disappointed. At least one of the baffles had already fallen down, one was completely plugged with insulation and most of the bays were not even full of insulation! I sent an e-mail to the salesman, he answered he was sorry and would let the office know. I never heard from them in two days? I sent another e-mail to the office directly on Sunday evening, as of Monday night I still have no reply? I paid the bill in good faith an ddid not demand they put the ladder back up to inspect the work. Nobody else inspected the kids work either that sprayed the insulation? The job Is not done and they don't seem to care to call back?? I would not recommended his company!

I am leaving this review to caution anyone from working with JB Custom. I got a quote and was…read moreassured by the person who came out to my house that they would be respectful of my budget and would come up with a quote based on what services I needed prioritized. We agreed on a plan and budget, which included ripping up carpet and laying down LVP flooring, along with drywall repair, paint and installing fans in the bathrooms and repairing any drywall that was damaged as a result of that installation. Before the project started, I asked if the baseboards would need to be removed and was told no. During the process of ripping up the carpet, they did in fact have to remove the baseboards, which was not discussed with me, and I was told they would do their best to keep that extra expense "at cost" and "as close to our original quote as possible." Also, hardwood floors were discovered. I had a conversation with them about what it would mean to refinish the hardwood floors instead of laying LVP and I was told it would save me money. They sent me a "change order" for this, which was roughly $1000 less than my final balance due, so it seemed I was saving $1000. It was an ADDITIONAL 5k. This was not clarified for me until after that part of the project was finished. The entire scope of my project was not complete, because I had to ask them to stop working on the house due to already exceeding my budget, repeated delays, confusion about whether they were hiring an electrician for part of the project, and unfinished work. While I was waiting for clarification on the additional 5K charge, the owner reached out to me to have a conversation about the project - he left a voicemail which I returned. He never tried to call me again. After several conversations with JB, I was told they would refund the cost of the baseboard (their mistake) but they did not offer to make any other adjustments to my total due for work that was completed. I can only come to the conclusion that I was deliberately misled. I agreed to hire them because I wanted to get all of my projects completed at once to save time. I am left with unfinished work that exceeded my budget by a few thousand dollars, and at square one with my bathroom fans and and other finishing work that needs to be done.

They quoted me approx $6000 for the total job. After the first few days we immediately saw so many red flags and was disappointed. Olivia, the project manager was rude, unprofessional and did not communicate with her own team and us properly. The crew would arrive at my house asking us what needed to be done. So once they reinstalled new drywall I could not believe how jacked up it was. Nothing was level! I complained and yes they came back to fix everything that I pointed out but what if I didn't say anything? The owner told me he would have given us a discount after all of this and I get the remaining balance sent in an email and Nop, no discount.

Before Erik left he gave me an estimate for attic and basement (Healthy Homes) as well the walls from (Cozy Walls Insulation.) They were out here the following week to complete the job! I have HORRIBLE allergies that can cause my eyes to swell shut to causing vertigo. I was concerned that the smell of foam spray would be an issue.

We run a blower door test and thermal imaging scan before and after the job, so you see exactly where your home was losing air and heat, and what changed once the work was done. Most contractors ask you to take it on faith. We measure it. As a Focus on Energy Trade Ally, we can also help you capture the state rebates your project qualifies for.

Then I brought in a couple of "mom and pop" type companies and really liked this one. Scheduling was a little tricky due to the season but we ended up getting it figured out! Helpful tip, it needs to be under 80/85 degrees for attic work, so this might be a great summertime project for people with flexible summer schedules like teachers or retirees or a great fall/spring project. Definitely would hire again and will recommend to neighbors. Thanks!
