"Kevin called me the same day I posted the pro request. I scheduled him to come by to do a quote two days later and hired him at that point. Kevin replaced a scary exterior electrical outlet and power cord that powers a pool pump. The power cord was coming out of the ground and arcing and the old outlet was melted around a socket. Not good. Kevin fixed it right up and replaced and greatly improved the whole set up, including installing an exterior outlet and switch that are both protected by the weather. Very impressed and will hire Kevin again."

"Eastern Maine Drainage was quick to assess our problem and Nate was able to set up an appointment within a few days to remedy our drainage issue. He was on time, communicated clearly, and was tidy with his work. Since I was at work while he was installing the new sump pump and drain line, he kept me in the loop about his progress. He had a detailed estimate that he stuck to, and he even deducted the cost of some PVC when he realized he didn't need as much as he initially planned. I would recommend him to anyone needing work in their basement."

"I highly recommend Octagon Cleaning and Restoration. We recently purchased a house on the water and discovered that we had a mold issue in our basement. Matt and his crew were professional, informed us what needed to be done and completely eliminated the mold and the musty smell. Matt was very responsive to my texts, answered all my questions and a great representative of Octagon."

"Everything went wonderfully with this company. They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work. Once they started, the team (three people came) worked together like a well-oiled machine. One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring. Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues. They cleaned up after themselves very neatly. They also replaced the light switch with a dimmer switch at no extra cost! Well within my budget, and came in even lower than their original (FREE) estimate! I would highly recommend this company to anyone in the Bergen County area.
