Common Questions & Answers

Q: If I have my windows replaced now,how long can I expect them to last?
Get Answer:
A: Much depends on the quality of window you have installed and the options you select. A high quality replacement window properly installed should maintain its usefulness and efficiency for 35 years or more.

Q: How do I, as a lay person, know the difference between a high quality window and one of lesser quality?
Get Answer:
A: If you purchase the highest quality replacement window or one of a much lower quality at a much lower price, once installed, to the average eye, they will look the same. However, once installed these windows will be subject to expansion and contraction, excessive climates and other vagaries of the weather, including wear and tear from operation(raising, lowering,sliding). Because of this, it is important to see what the inside of the window frame looks like and what is built into its manufacturer to deal with these elements. It is also very important to examine the glass package of the window. This includes glass thickness, coatings, gas, and spacer material.

Q: How do I see the inside of the window frame and how will I know what to look for?
Get Answer:
A: Most window companies will furnish a cutaway sample for the customer see the inside of the window frame. They will also have a small sample window to explain and demonstrate how the window actually works.

Q: How do I know what type of glass packages bests serves the needs of my home?
Get Answer:
A: The answer is complicated and will require research from the homeowner. In central Texas, we have a very long cooling season, so Low-E glass is mandatory, as is Argon gas between the panes of glass. A silver coating is also highly recommended. A qualified replacement window contractor will have studies available for the homeowner to best make educated decisions as to glass options.
