Extensions- 17 Dec 2023
Very poor experience, we employed Advance to build a 2 Storey extension unfortunately we had to terminate the contract of the company at first floor joist level due to consistent issues in regards to quality of build, not reading the drawings or spec leading to incorrect materials being used or sub standard materials for the project. Protection of property and general onsite cleanliness including leaving constant food and drink on our property. We had numerous issues with labour being onsite it was a build during winter that comes with its own problems however even good days were consistently missed with no communication from the management. We had to get numerous people out to review the build as it didn’t appear the onsite management understood the basic standards and requirement for the build. Finally after agreement and release of final pay the company refused to pay the scaffolding company for the works done on our property leaving ourselves with the further issue of scaffolding after we had paid. Whilst the company gave a cheap price it was just not worth the subsequent stress and issues caused by Advance construction and their poor onsite management.
