Our 30 yr old skylight was leaking during the winter. Andy replied quickly with a fast quote and followed up with a site visit. Andrei is very pleasant and knows skylights very well. We arranged for the first sunny day, even in January, to replace our damaged skylight. In one day, Andy removed our old skylight, replaced ice shield, flashing, and installed a brand new curb and skylight. Excellent work. He took pictures of the entire process and cleaned the area as he worked. Very happy with Andy's Skylights.
