I have used this company for over 10 years and would NOT use anyone else. Lance takes pride in his work and is respectful while in your home. He, and his staff are courteous and professional. Always dressed neat and clean (a huge plus). I have had him install showers, sinks, faucets, and even a full kitchen and bath remodel - the gamut. Everything is on point with this company.
