I had a BIG problem. My 60 foot poplar's center was diseased, and was growing in two directions, toward my house and toward my neighbor's house. I saw an ad in the Middleton Gazette for Treasure Valley Tree Company, plus one other company. They both diagnosed my situation, reaching similar conclusions.
I chose Mr. Armstrong and Treasure Valley Tree Company. He responded immediately to my call, and his bid was 25% lower than the other guy's. There was a snafu with the availability of some equipment. The job was postponed for one week, but the timing was not critical, so it was no problem.
Mr. Armstrong went above and beyond what was expected. He also cut down a smaller tree and trimmed down two stumps for no extra charge. He worked for two solid days in bitter cold temperatures. On the adjacent tree, in addition to the agreed trimming, he ended up cutting two more branches for aesthetic reasons, to make the remaining tree look balanced. When he was finished, the clean-up was perfection. You couldn't even tell he'd been there. He hauled away all waste, and threw the majority of wood over the fence for my neighbor, as arranged.
