we are currently recieving estimates to paint exterior 5,000 sq ft 2 story colonial...we are being told they will power wash, sc****, minimally sand house, spot prime, and 2 coat paint house, and caulk and reglaze 42 windows.They will have to use 60 ft lift as well. Estimates are all over the place!!! ($5,000-$17,500...)We have been told by several companies that manufacturers warranties are not relevant to older homes. That older homes (unless they are completely stripped) will need to be painted every 6-9 years?!!! Is this true to anyone's experience? help!!! Someone- advice- experience- please!
