Homeowners are often discouraged by contractors from purchasing or supplying their own materials. This is to prevent the use of substandard products in the projects. Most plumbing and heating services will include in their contracts that the customer is responsible for any damage caused by the materials they have supplied. To avoid such scenarios, it is better to allow the experts to supply the materials. However, clients can discuss with the contractors if they have any preferences in terms of where the materials are obtained from. This way, the client can receive expert advice on their choice of suppliers and the quality of their products. We source our supplies from credible names in the business, and while we aim for a flawless delivery each time, we do take full responsibility for any damage caused in the course of the project.
