A general contractor warranty is the best way to know that construction will be done correctly and in accordance with the design and cost estimate. If problems arise during construction, the contractor who signed the warranty will reimburse his customer for the damage. A contractor`s warranty is a typed or handwritten document completed and signed by the contractor that guarantees that the construction project will be prepared professionally and without major defects and meets the safety and quality standards generally accepted by the construction industry. The purpose of this document is to ensure that the contractor provides services to the best of his ability with the right materials. It is possible to add a contractor`s warranty to the construction contract signed by the owner of the construction project and the contractor before the start of the work. However, it is recommended to create a separate document to state in writing the contractor`s responsibility for the construction or repair of the project using the best possible equipment, materials and labour.
