There are important criteria to consider when thinking about the replacement or installation of windows and doors.


Most windows manufactured today are dual-pane to be more energy efficient and soundproof. The quality of the spacer — the piece that separates the pieces of glass — is important, and the better quality windows use argon gas between the panes to increase insulation. A poor quality spacer will fail in a few years, allowing air and moisture between the panes.



Vinyl frames do well in Hawaii as they insulate and provide protection from salt corrosion. Ensure the frames are chambered for strength and are resistant to UV rays.

If you stacked up all the brands of windows and put the heaviest at one end and lightest at the other, the heavier window will generally be better in quality; metal reinforced inside, thicker glass and vinyl.

Better quality windows use “neat” glass that allows water to sheet off the glass and not leave water spots. The rain or a hose will keep your windows clean.


While Diamond Head Windows & Doors carries many brands of windows, in its 20-plus years of installing windows, the Amerimax brand has proven to be the best in quality and value for money. The company ships directly from its factory in California, eliminating any middlemen and additional costs to you.



As important as product quality is, ensure that the company measuring and installing your windows are professional. Buying windows from one entity and having a subcontractor install them can lead to problems if there is a leak within five years. Diamond Head Windows only uses its own employees, who have years of experience in installation. The company can handle any aspect of your job, including expanding your existing windows or handling dry rot or termite damage.


Diamond Head Windows offers a lifetime warranty on both product and installation. If your window leaks within 10 years, call the company for repair or replacement at no charge to you.



Amerimax offers a lifetime installation that includes frames, glass, hardware and even screens. Diamond Head Windows also has a lifetime accidental glass breakage warranty. If it is a manufacturing defect, the company will do the work of getting the window manufactured and replaced, for as long as you live in your home.
