I received 2 quotes from 2 contractors for this work. Evergreen was very punctual, always on time or at least reasonable. Every person interacted with was professional. The sales person came to the house and gave a quote that day. I went to the other company who had already been out and they sent their quote, it was cheaper than Evergreen. I discussed this competitive quote with Evergreen and we worked out some details, I was assured that the job would be done right ,and since the 25 year warranty is reassuring I went with Evergreen. I think in the long run I made the best choice since the 25 year warranty is awesome and the other cheaper company had only a 1 yr warranty, however I would not recommend Evergreen unless you plan on checking on all their work personally. I was very disappointed in the attention to detail of some items, but it was odd because some things were done with a high level of attention to detail while others were not, very conflicting. The Story: Scheduled for 2 Day job, 3 people, ~900 sq ft crawl space often having standing water when it rained a lot. 1st Day, Monday - Installation guys discovered that the designed water trenches were not going to work well, they gave me the option to install a 2nd sump pump at no additional cost instead of the additional trenching challenges/risks. It was decided to install 2 sump pumps on opposite ends of the home. (Note: Sump pumps need serviced yearly, the drawback is 2 pumps cost more to service than 1 pump....I think 2 cost around $160, but I will not know till next year) The workers were friendly, respectful, professional, and worked hard. 2nd Day, Tuesday - It was raining so they decided to delay digging the discharge lines since it would tear the lawn up more. They finished the basic installation and I reviewed it. We discussed several things which I had expected to be different and the workers happily confirmed they would come back to hit those spots when they came back to did the discharge line. Outstanding items were: Needed insulation on one wall near the entry, couple spots needed additional sealing in the cleanspace, that evening I discovered the inside discharge lines had several PVC joints which had not been glued, the standard discharge distance is 15-30 feet from the house but in our quotation process I had thought we had agreed to more, that evening the sales person and I talked and we agreed to a good compromise of 45 feet (I had wanted ~70 to get it behind my garage, 45 was better than 30). 3rd Day Thurs or Fri? - The third day was just a few minutes to fix the leaking pipes and seal the places in the encapsulation, this was done. 4th Day Saturday - They returned on that Saturday Morning for a couple hours and dug the trench and installed the 45 foot discharge lines, other inside PVC leaks had been discovered, those were repaired as well. Unfortunately it was also raining this day, there was no sod to put back on top the trench since it was so muddy, I requested they put down grass seed, this is not their normal procedure, but they agreed to come back. After they left more leaks in the PVC inside were still present. 5th Day Monday - They sent out another guy not on the install crew, he looked everything over and went back indicating the installers needed to fix their issues, he did not want to fix their issues and did not have the parts he needed. 6th Day Wednesday? - The original crew returned and fixed the PVC, fixed some issues with the discharge lines and seeded. They also completed the insulation which had been missing. They spent most of the day as a result of discovering that I had a worse water issue than they had initially thought, more trenching was performed under the cleanspace and the cleanspace was sealed up again. I felt much better about the attention to detail and quality of the job after this day so I paid them Thursday. Sunday - I found still one more leak in the PVC pipe inside the crawl space, and a very small amount of water still coming in where the new issue had been discovered and mostly resolved on the 6th day. 7th Day Monday? They sent a worker to go over everything with a fine tooth comb. Sunday (3 weeks after start)- It has only rained a little in the week since the final work (7th day) was done and I have not had the time to go down there and check everything out, if there is anything else significant I will have to edit this review and let you know. For now I think things are ok and I feel safe knowing Evergreen/basement systems/cleanspace has a really good warranty. I have been disappointed by their attention to detail, they had to come back a bunch, but in the end I expect a long lasting product, only time will tell. Again, everyone was very nice and professional, otherwise I would be hopping mad about this job and the time required of me to keep checking every time it rained but since they were easy to get along with I am patient enough to also recognize that mistakes happen and people learn from them. As a result I expect your installation to go much smoother than mine.
