    Mrs. Philpin, Haverfordwest, November 2017

    Various coppicing and hedge reduction work
  • “Really impressive company. Right from the start we had excellent customer service, a prompt visit from a knowledgeable tree surgeon who gave trustworthy advice on our trees, including recommending leaving one of our big, old beech trees as there was no need to remove it. They sent their insurance certificate as standard when they sent the quote & dealt with any necessary permissions without us needing to be involved. The work itself was hassle-free, quiet, organised & carried out by a highly skilled team. We had two huge (100ft) fir trees removed which were both very close to buildings, but they had them both down, stacked & all brash chipped within a day, leaving the place clean & tidy. We have restricted access too, but that didn't cause a problem at all. Fair prices. Highly recommend & we'll be using them again in the future.”
