Sundek installed a new pool deck in July 2013. Great job, no issues, 100% positive. Our property seems to be more susceptible to ground expansion/contraction than usual, compared to our neighbors. Living in the house for twenty seven years I've seen more cracks develop in surfaces, from the garage floor, driveway, walkways, pool deck, and swimming pool walls than I ever thought reasonable even for South Florida. The houses here were all built at the same time, by the same builder in the late seventies. There's never been anything disastrous, but certainly noticeable. Our new Sundek installation was no exception. Hairline cracks appeared, grew larger with seasonal changes. Cracks in the original concrete base were noticed when two previous layers of material were removed/repaired prior to the Sundek install. Sundek's warranty covered any problems caused by poor application, defective material, etc. For obvious reasons, underlying issues not created by Sundek were not covered. When I called Corey at Sundek for advice he stopped by the following day for a look. He was surprised by the amount of cracks, some of which were three feet long. He spent some time examining the deck looking for areas that might not have been properly applied. We found nothing suspicious, no hollow spots, etc. I asked for any DIY suggestions, or a ballpark figure for patching and repainting the fifteen or so assorted cracks. He sympathized with my problem and explained that this was their busiest time with a backup of six weeks for work already contracted. If I could wait awhile until he had a crew in the area, he'd have someone come by and see what they could do. I agreed, and their was no discussion of payment at that time. About three weeks later, two of Sundek's men showed up, said they were finishing a job nearby and went to check the deck out. We walked the perimeter and found close to twenty cracks. After explaining what they would do, they got to work and spent about an hour in the ninety degree afternoon sun meticulously repairing and repainting all the damage. I'm sorry I didn't get their names because they were professional, neat, efficient and really good technicians. Sundek didn't charge anything for the work or materials, even though they could have, and I would have gladly paid to have the work done. I'm happy to recommend them as reliable, efficient and dependable. And a special thanks to Corey who really is a good guy. Sundek's customer care is second to none, and I appreciate their goodwill and after-the-sale service.
