Warranty

The manufacturer warrants that there will be no leakage in the concrete structure for a period of 10 years from the date of installation. This includes the seal where the two (2) units are joined.

The warranty does not include moisture that may appear from time to time in the form of condensation, commonly due to temperature variations, humidity, etc. Neither does the warranty include water that may enter the structure through the door or ventilator. Small cracks caused by expansion and/or contraction which do not create a leakage or structural problem are not covered by the warranty.
