Sealmaxx did an excellent job...they were timely, efficient, courteous and professional. Sealing and staining costs about 3 times what normal staining alone costs but is well worth it since they have a 25 year unlimited warranty. Worth every penny. We highly recommend their service. Right now the deck looks as good as new. I could not believe the change in its appearance. David and his crew are true professionals...they were on time and their work exceeded my expectations.
