We called Radon Technology Aug 23. He came to our house
to give us a free estimate the same afternoon. We called two other companies, neither of
which came to the house to make estimates but did email quotes.
We elected to use Radon Technology because the price was competitive, the installer is the company owner, the proposal suggested sump pump depressurization followed by testing and further crawl space remediation only if the initial remediation did not lower the radon levels satisfactorily.
We were also able to more confidently evaluate the proposal he emailed us after having discussed alternative remediation methods with him when he came to our house.
They came, on time, on August 30 for the installation, which took about five hours. They made recommendations about the options for routing of the vent pipe.
All work was performed efficiently and neatly. He cleaned up thoroughly. They left a testing machine to operate a 48 hour test. They came back, on time, to check the results, which did lower the radon below maximum allowable level.
