I get a lot of people bringing me frames that have had an accident or age has not been good to them. I really enjoy doing restoration work but it is tricky to give a price for, the cost of materials is easy but the amount of time it takes is always the difficult thing! Also, I often open up a frame (which depending on the previous framer can take between 5-25 minutes) and realise that just replacing a mount isn’t going to be enough, often there is damage to the backing board, issues with how the artwork has been attached etc. Then when it comes to resembling things you often find older frames are not very square – modern framing tools make getting angles right a lot easier – which leads to having to tinker with the mount, backing board and glass. What I normally do is try and give a maximum cost then charge for materials and hourly rate.
