I think that Paul provided a great, no pressure sales experience. Even though there were issues with the windows, I am satisfied with my experience.

Review of Kohler Bathroom Design Service by

· Mount Clemens

JoHanna was professional, prepared, and knowledgeable. She helped mw with the Kohler product line while working with the other elements I wanted included in my design. If not for JoHanna's help, I'd probably still be looking for fixtures etc!

Review of Glass Guru of Macedonia by

· Garfield Heights

From first interview to written estimate to finished project, this company provided service beyond what I expected. Crew arrived on time and worked until project was completed. Workmen answered questions, explained what had to be done and why. A good experience at reasonable cost.


I need to replace the insulation in my attic , can I install faced fiberglass insulation over the existing vapor barrier.
Jul 2, 2019
No need for s econd mositure barrier which is what the paper-face is. Just roll out unfaced insualtion atop the existing. Or, as an option, rent a blower and use loose-fill insulation. 
I just change my water heater, it is 50 gallons big, the thermostat is on letter "c" one level less that very hot. Why water gets cold in the middle of shower?
