"Consequently, this increase is also a signal to the landlords to be more mindful of tenant safety and security, even if it means reviewing the warranties of Hampton Roads replacement windows they have had installed in the property. Section 55-248.13 of the Code of Virginia outright states that it is their job to “make all repairs and do whatever is necessary to put and keep the premises in a fit and habitable condition.” Since this obligation can become costly, it would benefit the owner or landlord of the rented property to have a warranty that can cover necessary long-term repairs. Most window warranties are quite comprehensive and detailed. Some may provide total coverage for 20 years, and some may only cover glass parts for 20 years and non-glass parts for 10 years. Usually, the warranties only protect the owner from physical damages that weren’t done deliberately, but reliable window manufacturers are known to extend this coverage to natural wear and tear."
