    I am absolutely happy and so excited for my beautiful "awning" window in my kitchen above my white sink. It has totally opened up my kitchen like a brand new room! Now it is so light and bright it's my favorite room. Aaron recommended this type of window when he saw my older cracked window with dark wood and crooked screens! they installed my window so professionally and quickly and cleaned up afterwards! Wonderful work! You are the best.

    Schmidt Window and Siding did an awesome job installing the new windows. They were polite, professional and everything was super clean when they left. The windows will do a much better job with insulation and they look great! Thanks!

    The quietness is amazing! I live in the country near a railroad and my windows would rattle when the train went by. Now I don't even know when the train is moving!

    The whole job from start to finish was exceptional. Hats off to Schmidt Windows for everything.
