BEWARE of Denny Wiggers Landscaping, NJ Two years ago I hired Denny Wiggers of Denny Wiggers Landscaping in Paramus, NJ to put up a retaining wall for my home in New Jersey. The retaining wall collapsed and I have been fighting with Denny Wiggers and his company Denny Wiggers Landscaping in Bergen County New Jersey ever since to get the retaining wall fixed. Without a doubt in my mind...court action will be the next step. BEWARE OF DENNY WIGGERS. FRAUD WARNING...NEVER hire Denny Wiggers to handle any work for you, otherwise you will deeply regret the outcome. read full review »
