Called Giroud out for an estimate on removing two large pine trees in our yard. Their quote came back $3,000 higher than two other reputable tree-removal companies in the area, so be very wary . They quoted almost $5k and others are doing the same work - take down trees, haul away debris and grind stumps -- for less than $2k. Maybe they leave gold plated stump grindings behind? I can't figure it out...
