Most reviews praise Simon and Nick's responsiveness, skill, and warranty honoring. Yet two stark complaints document a dispute where the business allegedly took payment for chimney/waterproofing work, failed to complete it, became uncontactable, ignored legal judgment, and never paid court-ordered damages. This sharp divide demands careful contract review before engaging.
