"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."

"The estimator examined the basement walls and identified four cracks through which water might be coming in and gave a quote. We agreed to have the work done. One service man came and filled the cracks in less than the estimated time. The work involved surface patching the cracks on the inside of the wall, drilling approximately six holes through each crack and injecting a sealant into each crack. Since we haven't had a hard rain since then, we haven't had a real test of whether it holds water out.

"Chuck asked all the right questions before giving a quote and gave us multiple options to address the problem leaks. His serviceman, Josh, was courteous and professional, clean and efficient. They filled two basement cracks with the injection sealant and we are pleased with the results. I would use them again.
