For us to replace your plumbing lines, bear in mind that unless your floors and walls are already exposed for renovation, we will have to open them up. That is if you are wanting to use copper pipe. The other pipe option is PEX. It’s flexible, so it can be fed into the walls without opening them up. Also, it’s a far more affordable option. Not only installation costs, but also material costs, are lower with PEX pipe. On average, PEX piping costs half of what copper piping does. Also, it is more energy efficient and burst-resistant than copper.
