What Our Customers Say
Posted on Annette W.Verified I can't say enough good things about WC Decking. Probably one of the best experiences I have ever had with a contractor. Franklin, who came to do my estimate spent over an hour with me and answered all of my questions. The estimate provided was very thorough and included all possible scenarios. I knew that it was going to be a big job because we had a waterfall from our sliding door into our living room the last big rain (coming from the upstairs balcony). I had 4 other people come to take a look and only 2 of them even got back to me with an estimate. Pretty sure the job was over their head. Not WC Decking. They know what they are doing!!! Big shout out to Deion in the office, who was very communicative, Luis, the foreman who came to the property several times and answered all of my questions. And finally, to Kevin & Julio, my team who worked very hard and put up with me watching them work occasionally. They were always on time, cleaned up after themselves, and did a fantastic job. If you have leaking balconies, don't waste your time with anyone else...hire them already!Posted on Sharon C.Verified WC Deck & Waterproofing did an outstanding job at our condo building from start to finish. The entire team was a pleasure to work with and extremely helpful in executing the complicated process of restoring and waterproofing our twelve balconies and four rooftop patios, (many that were leaking into the condo units below them), and also the rear of building concrete and foundation. The team includes Business Owner, President and Licensed contractor Franklin Castillo, President of Operations Luis Aguirre, Foreman's Esvin Orellanna and Marcos, and Project Manager's Kimberly Paz, Suany Caceres and Massiel AguirreI. They provided courteous, professional and prompt service and would often go the extra mile to meet our HOA's individual needs. Any issues that did come up were handled promptly and professionally. They provided timely communication and updates and were very knowledgeable in handling all the different construction needs of our project. They also worked very clean and the pricing was very good. The balconies and rooftop patios and new concrete and foundation look absolutely beautiful and most importantly, no longer leak into the units below! All did a fantastic job in every aspect and our HOA could not be happier and we highly recommend them!!!Posted on Mark P.Verified The estimate was scheduled promptly and the representative was very knowledgeable and gave me plenty of details and ideas to mull over before making a choice with other companies. The installers then came in and were clean and they did the work properly and communicated their schedule and ended up doing a fine job. I would recommend them to anyone requesting a deck.to be resurfaced.Posted on Sparka Lee H.Verified wonderful job, good customer service someone came and cleaned up all the "aftermath of the work" ! the decks are beautiful, they are an upstanding company, i would recommend!Posted on April R.Verified I contracted West Coast Decking to remove and replace the deck system on one of our balconies. They did a fantastic, professional job from start to finish. The company was a pleasure to work with. I will definitely use them again on future projects and I highly recommend them.Posted on Andrea S.Verified This is the best company I have ever worked with!!! Always on time, great advice, they go above and beyond. Pricing was more than fair, and the job was beautiful!! I highly highly will recommend them anytime!!!Posted on Norma G.Verified West coast decking are awesome, And professional. Job was excellent didn't have any issues. The job was quick.Posted on Laguna U.Verified We are pleased with Deck Waterproofing. Their employees were diligent and professional. They showed up on time and began the job as promised. We rate them highly. It did take a week to match the color of my stucco to the original shade, but overall, I wish more contractors were like them.Posted on Karen C.Verified Excellent quality work with rapid, clear and professional communication. My job ended up being much more involved than anticipated due to unforeseen problems. Frank was very patient and knowledgeable regarding explaining the problems, and both Jose and Alex very clear in showing me issues and solutions. Kimberly was exceptional in coordinating technicians and communication. Overall, a very high quality company both in terms of product quality and customer relationships.Posted on Steven W.Verified Highly recommend West Coast Deck Waterproofing. As a general contractor I know the difference between quality and shoddy workmanship. West Coast's crew was meticulous, efficient and knowledgeable. They always showed up on time and they took their work seriously. I couldn't have been more pleased
