    Do not work with this contractor. I hired them to perform site work for a manufactured home. The owner/principle argued with me at every step. His methods of performing work are unorthodox, to say the least. The company is in need of cash flow, and they bill whenever they need some, unlike most reputable contractors I've worked with who bill monthly. His crew does sub-par work. The do not know how to pour concrete in wet, cold weather.

    What a smooth and professional operation. These guys are very skilled, polite and really know their stuff. Chuck explained the process in laymen terms which is great because I don't know much about septic. I know how to repair Mac and PCs - going on 27 years. Nevertheless, all went better than planned and expected. The big hurdle was the mountain rock they had to break through to get to the sewer on Northshore Rd. Amazingly they broke through quickly. They took the overwhelm the job with equipment and crew approach which worked very well and fast. Even the permit official was impressed.

    They did a fairly good job at the things they did, but they never returned to finish the job and never responded to any of our requests to finish and therefore, we had overpaid for the work that was done since the contract was NEVER competed despite many requests!
