Check out the construction of this wall. Lath and plaster were commonly used in construction in the United States up until the late 1950's. After that time, drywall began to replace lath and plaster construction.
If your house has lath and plaster walls that means that your pipes (unless they have been updated or replaced) are probably 60 years old or more.
Working with these old pipes takes practice and skill. Luckily, Anthony has been working in South Park and the surrounding areas for over 20 years and has a TON of experience with these older systems.
If you have an old house, give us a call, we are happy to help.
