Howard R.

Because of weather problems Lora and crew were here two weeks early. Scot and his helper cleaned out the trash in the crawl space and prepared to put down the vapor barrier. They did this job a bit out of order because of the COLD weather. The morning they started it was 16* ! Their first task was the vapor barrier. After that the spray foam insulation. Then the old insulation was removed and hauled away. Lora did the job in this order because of the COLD weather. She told me she would NOT leave us with no insulation for any amount of time with temperatures this cold. Lora cares about her customer and works very close with them . She even let me work with them a little bit. I'm an old retired Marine and still like to be involved. I don't think I got in the way too often. Her prices are very reasonable; there is no reason for negotiation. I'll definitely be calling Lora at Green River for any other needs around my home. Thank you Lora & Scot Howard, the Troll

A++ We could not be more pleased. Lora and her crew were great!! Lora and company went over and above to get us scheduled with short notice due to my husbands work schedule and have animals that needed to be out of the home as well as us. Communication was wonderful, we knew when they would arrive as well as explained all aspects of the work being done. They arrived on time, did an amazing job, they cleaned up everything. We wish everyone we have ever hired was as professional and did as good a job as Green River. We already know we will be hiring them again most likely more then once. If you looking to hire and honest and great company Green River is that company! Thank you all so much for an amazing job!

The work initially contracted was not completed: the pavers continue to be covered by a film (despite their contention that it would wear away); mortar splashes on the walls have not been cleaned. Secondly, the cover for the cellar entry is totally unacceptable. Although they claim that we never mentioned that it should be waterproof, that cannot be substantiated: it is clearly written on the paper we initially used to discuss the work to be done; I certainly mentioned it orally and reminded them that it was in the context of being waterproof that I mentioned how silly I was to buy the decking boards since they could not possibly be waterproof; and why would I replace a perfectly good cover, needing only painting, if some other additional quality was not needed. We had several discussions about the plywood and I certainly did sign a contract specifying plywood. However, I continued to believe that it would be waterproofed. It clearly is not since the plywood itself is warping. Furthermore, the workmanship is appalling. In addition, they have charged us for 17 windows, but there are only 16 and it is not clear that the window in the shop has been repairedd The two casements appear to have been repaired, although the material is already cracking; the two fixed windows between them do not appear to have been repaired. Furthermore, the driveway repair is barely acceptable: the surface is rough and is not the same level as that nearby. We contacted them because of an excellent rating on Angie’s List and because they listed their category as masonry. Although most of the remaining work was well done, the items above are far from excellent.

Green River does not feel that this customer has been fair in these reviews and disputes what has been said. We also don't think that it's fair for the customer to give two negative reviews for one contract. We have a more detailed explanation of our response on the other review from this customer. We also feel that Angie's List has pressured us to refund the customer's money in order to remove this review. This is wrong. We did the work and did a good job. This customer is not being reasonable. Thank you.

I would highly recommend Green River - they were professional, competent, and responsive. Lora Corder, who came to my house to work up a quote, was very knowledgeable and helpful. She promptly emailed me my quote with pictures of other work the company had performed. When it came time to schedule the work to be done, Lora was very responsive. On the day they did the work, they were right on time and finished all the work that same day. As a bonus, Lora was very familiar with the TVA eScore requirements for air sealing and insulation, and she immediately submitted my paperwork so that I could get my rebate. I will definitely use this company in the future!

The work on the walls and walkway were done well. However cleanup was not completed: there continues to be a film of mortar on most of the walkway; wash splashes on the walls were not cleaned and remain. The quality of the work on the driveway is poor, the repair being not much better than the previous status. The "deck" was to have been waterproof so that the area below stayed dry, but is only a piece of plywood, no seals anywhere, plywood is now warped; not, of course, waterproof; and the quality of workmanship is such that they should be ashamed. The window seals appear to have been replaced competently, but the cost seems excessive. They also charged us for one more window than exists. After work had started, the contact person was less than cooperative. The work was done in late summer/early fall. I paid the final bill in September while they were not yet finished (clearly irrational behavior on my part). In late November, we received a letter from them stating that they would not do the "add-on: work, that they had over-charged us for some part of the work but did not charge us for the proper number of windows, and included a check for the difference. I wrote back stating that they were not done for the reasons above and that the original count of the windows was correct. I have heard nothing since.

Service Provider Response

Response to Complaint (Note: Attachments mentioned have been provided to Angie's List, as they cannot be uploaded here). Dear : [Removed members name], Green River is very regretful that you are unhappy with our work. As we do with all our customers, we have striven to provide you with the very best service. It is our belief that our work was in full accordance with the signed contracts and was of good quality and workmanship. However, after beginning work for you, it became evident that we were unable to meet your expectations, and we elected to not perform the remaining contracted tasks as a result. As to your specific complaints, we installed new gaskets on 2 casements and 17 double hung windows. However, there was a billing mistake due to information you provided. You initially told us there were 4 casements and 16 double hungs that needed re-gasketing (copy attached). We used this information to establish the invoice before work was done. After your initial complaint, which was before all work was complete, I came back and recounted each window that had been re-gasketed. I determined we had re-worked 2 casements and 17 double hungs. The invoice was corrected on November 11, 2015 and a refund check was issued along with a letter of explanation (copy attached). As for your complaint about the price for working on the windows, it was provided to you in an estimate prior to your acceptance of the work and you agreed to it. We feel it is reasonable based on time and materials required to do the work and you must have felt so also or you would not have signed the contract. You have complained that the concrete patch on the driveway does not match the existing surface and is not much better than what was there before. Attached are before and after photos of the work. The concrete we replaced in the driveway was cracked and had sunken in to create a big pothole. We sawed it out, and added metal dowels as reinforcement which we tied in to the existing to prevent it from sinking. We gave it a broomed finish as stipulated in the contract document. It would not have been possible to achieve a perfect match due to the age and condition of the existing driveway surface and this was stated in the contract documents. You have complained that the patio area at the entrance to your home was not done to your satisfaction. This area was rejuvenated by first being power washed and then being given a new grout coat by floating the entire area. We were very careful not to get any residual material on the windows, walls or door. However, please be reminded that you had water sprinkler repair men and HVAC repair men and others walking across the area while we were attempting to conduct the repair and after it was complete, and we had no control over their conduct. Before and after photos of our work are attached. As you can see in the photo, we protected these areas during work, and there is no residual material on them. As for the continuing bleeding, resulting in a film on the mortar that you are complaining about, I did not see any evidence of this when I returned to discuss your complaint. You have complained that the cellar cover is unacceptable. Before and after photos are attached. The cellar area was given a new cover in accordance with your specific instructions with respect to materials and method and with the contract documents. Please be reminded the documents called for a plywood cover painted white, with a trapdoor in the center. It was your desire not to install the cover over the top of the brick wall, which we recommended so that water would be kept out. Instead, despite our best efforts to convince you otherwise, you made us install it inside the wall, so that there was a gap. It was also your desire to install a trapdoor in the center of the cover, which again, we recommended you not do because it lets water in. It was also your desire not to install roofing material on the cover, although we highly recommended it in order to keep water out and protect the materials used. We warned you the material would fail as a result. As for you paying us in full before work was done, we were paid for the work we did on the original contract and on the change order work at the times that work was completed. We wish you the very best and hope that these answers help to clarify this situation. Thank you.

We bought a house that we knew had humid crawl space. The previous owner didn't even have vapor barrier. Green River, LLC was one of the crawl space experts we asked to come out to evaluate and recommend remedies. Other companies just looked at the crawl space and recommended costly remedies including encapsulation and dehumidifier installation. Lora was very different in that she spent over an hour evaluating crawl space and house exterior systematically. She suggested that water entering from gutter into crawl space was a factor. She sent me a detailed proposal to extend gutters and encapsulate crawl space (includes spray foam, placing thick vapor barrier, removing humid fiber glass insulation, conditioning crawl space, duct insulation, and shutting vents.) The price was reasonable for such an extensive work and less than what other companies quoted. Lora always let me know when they are coming out to do the work. She spent significant amount of time supervising the workers. She was considerate to have a port-a-potty brought in so they don't need to use our indoor restroom. Everything went very well and they always cleaned up nicely. Duct insulation qualified for $200 rebate from TVA. TVA person who evaluated was very impressed with their work and said Green River always does great job. If we need a contractor in the future, we will be contacting Lora. She is responsible, spends time to explain, and returns communication promptly. I can highly recommend Green River, LLC.

We moved into a "new" house that only had a few inches of nasty insulation in the attic; the heating and cooling bills were very high. We had Green River give us an estimate that was lower than some of the well-known competitors in our area so we went with them. They did a fantastic job, answered all of our questions, and cleaned up very well after the job was done. We also had no trouble passing the TVA energy right inspection once they were done. Our electric and gas bills are significantly lower now, too! I would use them again in a heartbeat.

We recently contracted with Green River LLC to do some energy upgrades on our house that would be applicable to the TVA eScore program. We air sealed the attic and the crawl, insulated knee walls and attic entry door, added attic insulation, sealed ducts in the attic and crawl, encapsulated the crawl (floor and walls), and other miscellany. Let me tell you about our contractor. The quote we got was the most thorough, detailed, and professional I have ever seen. The price was absolutely competitive. I had several questions about the project and the TVA program, so I exchanged a few emails with Lora (one of the principals). Her replies were very timely and answered 100% of my questions. The contract was signed, the work was scheduled, and the crew showed up at the exact time I had been told to expect them. The crew was excellent. They were here every morning and got right to work. They answered all of my questions and were always friendly and professional. The work done was just beautiful. This crew is obviously highly experienced and cares about producing great results. The materials used were of the highest quality. As an example, when I asked Lora about the vapor barrier material, she told me about the ?Stego? that they use. You can look that up - I think it?s some high-quality stuff. In summary, Green River is a company that earns an A+ from me, and I would never hesitate to employ them again or to recommend them to family and friends!

Great. Because of Charlene and Lora's knowledge, we were able to get our house back up to par / code. We've all heard how men hate to ask for directions but being an old, crusty retired truck driver, even I needed to ask for help / directions. I would not hesitate, and will, use them on upcoming projects.

Lora bent over backward to help me navigate the miasma of estimates on additional work for air sealing and insulation. She even went so far as to make an 'apples to apples' chart that explained how the various bids compared. I am looking forward to working with Green River in the not too distant future!

Description of Work
I received requested third party advice about work that had been done by another vendor. Lora was very thorough and professional. She noted that I should request the work be completed properly and took photos, sending me copies with a detailed explanation of why the work was substandard, since I had no way to articulate what her experienced observation had found. I highly recommend this company.

I was very impressed with Green River's quality of work. They are very knowledgeable about a wide variety of construction issues, not just energy improvements, and they show great attention to detail. They explained all of the steps in the process to me, in a way that was easy to understand, and they presented many options without pressuring me. I own a 100+ year old home, and they understood the history of its construction and the best ways to improve it. The energy improvements made a big difference in my comfort level upstairs during the summer and in my energy costs during the winter.

Lora and Charlene with green river have been a joy to work with. They are very helpful in planning and explaining their process and how it will help the house long term. Green river did rehab work on my basement, including insulating the basement and repairing existing ducts. I would trust these knowledgable women!!

They were very professional and knowledgeable, using state-of-the-art techniques to increase the energy efficiency of my house. They discussed various options and the advantages/disadvantages of each as well as the cost differences. They discussed each phase with me so that there were no surprises. The subcontractors they chose were skilled in their area, respectful of my property, and diligent in completing the work. The TVA inspection following the crawlspace work was highly complimentary of the quality of the work. I am extremely happy with the energy star metal roof that was installed and pleased that the leak around the stone chimney is finally fixed. Overall, this was as painless a home improvement project as I could hope for.

Description of Work

Project started early on 8/24. Completed initial work on schedule 10/4, with a slight extension beyond to apply another coat of paint because they weren't happy with coverage. Another extension to add roofing work, once this issue was discovered. All work complete as of 10/21. Charlene has 25 years experience as a general contractor and it shows. She and her partner Lora are professional and responsive. They can be tough and will tell you what is and is not possible or practical. They can also take general direction and decide details themselves. But can also accept ideas and details you may propose to them. Communication was handled via phone calls, emails, and texts. Very responsive to all media. This was my Dad's house in Knoxville and I live in Georgia. Most of the contact was remote and they were good at sending pictures so I could keep abreast of action. I needed very few trips to handle this project. Either Charlene or Lora was present at the job site whenever subcontractors were working. The one time this rule was broken, they fired the guy. When we started, this house was not possible to sell. Our initial buyer backed out when he saw the inspection report. I learned of Green River from my realtor who had a positive experience with Lora doing an energy audit and refit for her. So I sent them the inspection report and commissioned a design only. They produced the drainage system design and made recommendations and I ended up hiring them for the entire job. As a result of their work, we are now listing the house at $30,000 more than we were on the first try. I have no doubt we will sell it quickly. Every one of the red flags in the original inspection report has been cleared. Green River specializes in projects with an environmental component--hence the Green in their name. They treated my house to the full measure of EPA rules. Primary concerns were potential for lead paint and asbestos in the wiring. They used asbestos-rated vacuum procedures and took great care to follow the rules regarding lead paint, based on the age of the house.
