I had a very similar situation with 'Will Reno's' quite recently in which Will came by the house, looked at some work to be done on my fence and back porch, quoted me $8,000.00 for the work (plus HST but didn't give me an HST number), and took a $3,500.00 deposit for the work and then after taking a portion of the fence apart and leaving the garbage on the driveway, started making excuses as to why the job was bigger than he originally thought that it was and never finished what he started.
After numerous conversations he promised to pay me a portion of my deposit back which has never materialized. To date, all I've received are promises to re-pay me which he's missed each and every time that he's made them.
Other's in my area have had the exact same issues with this contractor as I have and many have yet to either see their money returned or their projects completed. Stay away from Will Reno's, Will Interiors and this contractor - you'll just be disappointed.
