It's really up to you. If you have the skills then it might be cheaper overall especially if there are other home repair projects that require professional expertise as well, so consider hiring someone else instead of juggling multiple tasks at once yourself! Either way, always remember to get estimates first before making any final decisions because prices can vary considerably depending upon what’s being done and how skilled/experienced your chosen contractors are in general. Remember too that old materials like bricks or flues may come with additional fees attached since they will work best when installed by experts who know their trade inside out!
