Spray Foam Insulation Installation
$5,000
They sprayed both of my attics in 2020 for $5000. There is a wall they did not spray in one of the attics and since they did not spray it - I have an issue with condensation from outside to this area (causing a pocket where moisture is getting trapped). I'm not the professional. It's not my responsibility to know where to spray and not spray. Lee should have noticed this would cause an issue over time but no one told us. I've had 2 roofing companies look at my roof and there is no issue with my roof. This issue is caused by condensation from 2 different temps meeting because they didn't spray this section. Lee and the general manager won't even come look at my issue to fully understand what I'm saying to them. He said it's over 2 years there's nothing they are willing to do. BEWARE.. they apparently don't know what will and won't cause issues down the road. Use a more professional company with better ratings and warranty behind their workmanship.

Gutter Covers and Accessories Installation and Replacement
$450
The only positive thing I can say about this company, is the price was very low. (450 vs. 1600 from other vendors). Unfortunately, that price was made up for in the lack of quality and professionalism received. When we hired this company, at my own mis-judgement, I paid in full since the amount of work was so low, assuming this simple project would be completed shortly. Lesson learned, I will never again pay in full for a job until it is completed with satisfaction. This company had our money for months before finally coming to our home to install the gutter guards we purchased. I followed up with our sales rep several times, each time met with an excuse of rain and being backed up. I'm not completely ignorant to construction services and I do understand being backed up. However, I don't understand or accept a lack of communication. The gutter guards were finally installed on a day when were having other work completed at the house. I emailed that week specifically to ask that I receive an advanced notice so that we could sort around the vendors coming to the house. Next thing I know, with no notice or discussion, the workers are installing the gutter guards. I discussed with both our vendors working at that time, and everyone was able to work simultaneously, so the work continued. I thought this was finally done and we could move on. However, I noticed in the corner of the house, the rain was gushing off of the roof and, through an upstairs window, was able to see the gutter guard was installed upside down. I contacted our sales rep who said he would open a ticket and resolve the issue. Another six weeks and several follow-ups passed before anyone came to the house. When someone did come to the house, it was not to correct the issue, but it was our sales rep to make sure I had not mistaken the installation. These are gutter guards people, they are either correct or they aren't. I stood and watched the sales rep attempt to reach the gutter level with a 6' ladder. Why? I don't know. But that attempt ended with zero progress. After further discussing, the sales rep still did not believe as made obvious by his discussion on why the rain my be coming quickly off the roof. So, at that point, I had to invite him into my home, take him upstairs and look through the window. It was only then that he agreed the gutter guards were upside down. I was told at this time, again, that a ticket would be opened. The next week, I saw someone accessing the roof through my bathroom window, again, with no advanced notice. I just shrugged it off and was thankful the work was being taken care of. However, when I checked, the gutter guards were STILL installed upside down. After another discussion, another rep and another week, the gutter guards were finally corrected. In the end, the gutter guards are correct and they work as they should. But the customer service and lack of communication through this company is unacceptable and will never recei

Need to call the customer more to update and communicate on timing of the project. I had to call 4-5 times to get things rolling.

New insulation and vapor barrier required quite a bit of cutting. I am pleased with the quality of the work done by Luke and Alesia. Renn was easy to work with; their quote was prompt and fair.

Blown In Insulation Install or Upgrade
$500
They were terrible at communicating. I had to call and follow up about 3 times to finally get the insulation work we wanted done scheduled. Then I had to follow up twice to find out what time the workers would come on the day we had picked. I was told 1pm, then they showed up at 9am and said they would come back later. They did not return later and I ended up having to reschedule for the following week. Once the work was actually done, it appeared good. But the poor communication was very frustrating and unprofessional.

Eric was excellent on follow up. The job was putting vapor barriers in crawl space and tack up the insulation There initially was a mix up on my request but it was quickly resolved. I had contractors call me and provide estimates but Reen was BY FAR the most economical. Would not hesitate to use again.
