We were impressed with all of our interactions with Euro Star, from choosing and ordering the doors via Igor, to the meticulous on-site work by Danny and his associate, and the excellent response by Danny and Alex to a minor glitch discovered after the doors had been installed. (The manufacturer had omitted a portion of the screen latch; Danny informed Alex; Alex came over and installed the missing piece the same day we called.)
Danny also identified the source of our decades-long problem of water coming in at the basement ceiling and running down the wall during heavy rainstorms: In '94 when the patio doors were first installed, the contractor slanted the concrete stoop *towards the house*, and his caulking was insufficient to repel the water that spilled over the gutter and splashed onto the stoop during torrential rainstorms. (The eavestrough and downspout specialists we had in a few years ago failed to identify this error, and needless to say, their 'solution' did not solve the problem of water coming in.) Danny not only corrected the true of the door frame, he ensured that the caulking was absolutely thorough. (It looks terrific too.) No water has come in during subsequent rainstorms. He also wasn't satisfied until the doors were running perfectly smoothly and easily; they now open and close with fingertips, whereas previously both hands and considerable oomph was required to get them open.
We have no hesitation in highly recommending Euro Star Windows and Doors.
