Other estimates came up with..your doors are "custom $$$" .."we can replace but $$$".."here's our cost $$$"...yada yada...When Tony from K&J Windows came to our home..every word he said was sensible and the cost was reduced because Tony thought about our "custom sized" replacement French doors and came up with a solution. A line of windows & doors that they install (good quality Simonton) that could still be considered a STOCK size. This, fortunate for us reduced the price significantly. It was so good we almost thought it was too good to be true! Just as he said from the second we said YES to our order, to the scheduling and to the install..there was not one kink, question or problem. The installers (John & his brother) were prompt & worked extra long to do our job in one day! With their respectfulness to our home, the cleanliness and their skill ..well let me say we are so proud and happy to have our new sliding patio doors. The quality, the ease, the retrofit on the install in our old 1980's replacement worked. Even with the surprise that our old french door were built into the old frame of an old imbedded slider they did what was necessary to bring things up to par ..they went above and beyond to do our job as if it was there own home. The pleasure was all ours. Thank you
