Hi, I own a leasehold flat and the roof is being done. After putting the scaffolding up the roofer told us that the chimney also needed doing and gave us a very expensive quote and told us unless he did the work all of the roofing cost would lose its guarantee. I could just about buy the argument that he couldn't see the chimney properly until the scaffolding is up but now he says my velux windows have to be replaced. Again his quote is very high and again he says if I don't use him the whole job will not be guaranteed. I feel like I'm being blackmailed. It was the freeholder who agreed to the terms of the contract. Does anyone know if I have any rights here? I have quotes from other firms to repair the windows at almost 1/10 of the price! Thanks
