Not sure if your tree is diseased? Afraid it’s dead? Or maybe it’s just grown too close to your house or become an eyesore. We provide a thorough, expert evaluation to figure out if removal of your big trees is necessary. If so, we strategically remove branches and then the trunk. You can keep cut-up branches for firewood, or we will haul them away.

The final step in removing a big tree is excavating the roots and stump. We provide stump grinding to prevent injury and infestation. Even if you’re an avid DIY-er, stump grinding can be difficult and dangerous without our expertise and heavy equipment. Let us do the dirty work. We’ll grind your stump and remove the wood chips, unless you want to keep them to use as compost or flowerbed lining.
