Reassuring and trust worthy.. He put my worry at ease the day we met.. I couldn't get hold of others and most were full of canceled appointments . The entire FREE estimate and job bill was on time and extremely organized. His knowledge of the trade was impressive and his sweetheart of a worker accents him well and we didn't need to worry about personal items or a mess left behind.. these guys are the best . I highly recommend.
