"HIired Serge Home Improvement, i for a partial remodel of the kids bath-new shower surround and flooring. During the time, I got the bid and he started work, the laundry room flooded and I asked if he could work on that too. Serge worked with the insurance adjustor and myself to bring the bid in at the insurance companies expectations. He had the laundry room up and running in a couple of days, with lovely new trim. This was a huge relief, as I had now washer for 2 weeks and laundry was piling up. Most of the bids I got for the bathroom work were in $15-$20K or more range. Serge's costs were reasonable and we agreed on what he'd provide and what I'd provide-tile and surround. When asked why the tub should be replaced he explained he wanted to make sure the plumbing was correct. He was right about that, the previous owner had "tiled" himself and done the plumbing. It was mess but Serge fixed it. Furthermore, he used lots of water proofing which gave me peace of mind as the kids splash like crazy. In 2 weeks, the bathroom was finished, and ready to use. I had him re-caulk my tub, and replace light fixtures in the dinning room and family room. It cost a small bit more than I budgeted, but having done remodels in the past I expected that. We are thrilled with the updated bathroom and new light fixtures. I a already discussing future projects with Serge. The best thing about Serge is his doesn't do mind doing projects on your house off and on. My previous contractor stopped taking my projects, because "projects to small and piece meal". Thankfully, Serge doesn't have that attitude."

"We hired Ryan with RCS to install a new sewer line for us. It was a huge undertaking that involved him drilling into *lots* of concrete and getting it connected to the city street. He was very communicative from the beginning and got the job done in a timely matter. I got 3 bids before going with him and can say that he is more than fair with his pricing. I would definitely recommend him to anyone for their sewer needs."
