RCC Waterproofing Oshawa

In the spring I had my worst nightmare come true my basement leaked and flooded my crawl space ugh. Ramy from RCC came and I felt better talking to him and having his expertise in this area. I hired him immediately and when the crew came Darwin the crew supervisor was very confident and told me he would solve the issue. They found the leak, dug down to the weeping tiles and replaced it all. It was like watching the 7th inning stretch lol. They never took a break and when it was done they cleaned the area and swept the driveway. I would highly recommend RCC and Ramy and his team. It is a huge relief and I can sleep at night again without worrying about it flooding.

We hired RCC Waterproofing to fix ongoing water issues and mold buildup in our basement, and Nick and crew did an outstanding job on the outter foundation. The team was professional, thorough, and clearly experienced. Michael and crew properly waterproofed the basement and completely removed the mold, leaving the space clean and dry.

Communication from Daniel was clear throughout the process, and they cleaned up well after themselves. We’re very happy with the results and would definitely recommend RCC Waterproofing to anyone dealing with basement water or mold problems.

I had an amazing experience from start to finish on this project thanks to the RCC Waterproofing team. Daniel was the gentleman that came out for the assessment and quote. Chris was the assigned technician for my job. Daniel was very personable, professional and knowledgeable during the whole meeting. He spoke with passion and concern which gave me confidence. He recommended what I should do to meet my needs in the situation I had presented. I followed his advice and when all was said and done and job was completed there was a big sigh of relief and a big smile. When Chris arrived onsite for the service, and I met him I got the same feeling of passion from him as Daniel which gave me confidence from the start. He was very knowledgeable and thorough in explaining what he was about to do so I knew what to expect. When all was done I was very satisfied and my expectations were completely met. He was very personable during his stay and made me feel very comfortable and would not leave until the service he provided was to his high expectations which was great. All I can say is WOW!! Thanks Daniel, you made my day.
Thanks RCC Waterproofing team for providing an awesome service
“GREAT SERVICE”

Recently has my house waterproofed by RCC and I will admit that I was a bit scared on the process and the cost of this project. From the moment I was reasonably quoted right down to the day the work was completed I was explained everything.

From the moment the workers arrived they were absolutely professional and an absolute pleasure to speak to. They were very clean and made sure to have everything back to normal when they were done.

Although this is not a cost that any one wants to incur but unfortunately we sometimes have no choice. That being said if there is ever a reason for me to need any services from RCC I will not hesitate to use them again.

The team at RCC were fantastic. Justin S always responded quickly, was professional and educated me on the process. Once we decided to move forward the work completed by Chris I and his team was great. The took the time to protect our hardwood floors, were polite, courteous and efficient. Our job was done in two days and they left the work area spotless. There are plenty of options however I would only choose the professional team from RCC.

I highly recommend this company.. they give you options and evaluate the job and keep you informed about it as they were doing it..could of made it a bigger job just to get more money but just fixed what needed to be done.. appreciated that.. and people working there are awesome from Nicholas and secretary who helped me and funny nice Chris I ..they were careful of furniture they had to pass with tools and buckets and wall cover etc but always made sure they didn’t bang it.. and even watched that my dog was around..loved them.. I hope I never need them again but if I do that is who I will call..Thanks RCC .. and I must mention Lachate ..the only name I never got was Chris’s helper but he was great too

The work on my basement was completed on time and I was extremely happy with the results. George and Michael did a fantastic job. Nicholas called to follow up which i found very professional. Great work by everyone.

Someone came in to check crawl space and exterior, took measurements etc. I was supposed to receive a quote, never heard anything back.

I had a leak in my basement and called RCC to come and diagnos the problem. I did research on the internet and found great reviews on this company that has been in business for over 100 years. The next day Nicolas Theodorace waterproofing consultant arrived at my door. He was very friendly and professional and diagnosed three cracks in my foundation. He quoted a very resonable price for the repair, less than I thought it would cost and I agreed to the work being done. About a week later I met Jeffery and his crew who were also very friendly and professional. The four man crew took down the fence on each side of my house and even moved my garden shed. They hand dug down to the weeping tiles and did the repairs and then replaced the fence on both sides of my house and the garden shed. They did this in about seven hours or less, they worked like machines, I was so impressed by thier work ethic. I would not hesitate to recomend RCC to all of my family and friends and anyone with a wet basement. There is a reason this company has been in business for over 100 years and it is the people like Nicolas and Jeffery and his crew.

The guys just finished work on our property which only took them one day to do. Our foundation has been fixed and time will tell if its going to leak again. Just looking at the waterproofing process that was done, I think that we will be more than fine from here on out. This team was professional and followed the process to the tee. Great job RCC crew.

Even with the times being the way they are right now, RCC Waterproofing remained open and was able to come to our home and fix our basement. We had them do some underpinning in preparation for us selling our home and they did a fantastic job. They followed Covid safety procedures even. Im super happy they were open for business and Im super happy they help us. Thanks a bunch.

I'm glad I chose the wet basement people to take care of this basement leak! RCC was great!

By George Stoetes on Feb 29, 2020 Verified by Email

they didn't lie when they said they are one of the best waterproofing companies. RCC did a great job taking care of our leaky basement! Kudos to a job well done. Special thanks to rep George who coordinated everything.

Clean tidy and hard working. Those are the things that come to mind when I think about the RCC team. Good job crew.

George was instrumental in getting this waterproofing done. It was at 30 ft of waterproofing that need to get done and he was able to coordinate everything along with Roger and crew doing the digging and parging. It was a team effort. Everything was done flawlessly and I am very happy with the results :)

The work done by this group of gentleman is astounding. George was also a great person to work with through the process as he made it simplified. Waterproofing with these guys was easy and we are going to have them come back at some point to do the interior of our basement as well. Pricing was very reasonable too. I recommend these gentleman and company RCC very highly.

Thanks for coming in and assessing our problem. Professionalism all the way, thanks RCC.

By John Winters on Nov 20, 2019 Guest Review

An underpinning job was done with RCC over a couple of months and they did a good job. They emphasized making sure the place was structurally sound and worked with all the paperwork in mind. The job was not cheap but RCC was willing to work with us on the price and they offered us a competitive price. Thank you to all the RCC staff for the job and we recommend them if you need anything basement related done.

By Paula Jones on Oct 29, 2019 Guest Review

RCC has great pricing that was very competitive with the other companies. The thing that sold me was the lifetime warranty. When the crew members came to do the work, I knew we made the right decision just based on their friendly demeanors and work ethic. Overall a very good experience.
