"Excellent job on the window tinting project. The quality of the work is top- notch, clean precise and professionally done. The tint not only enhanced the look of the home but has reduced the glare and heat, just as I had hoped. Cassandra was respectful of our space and left everything spotless after the job was done. I’d highly recommend to anyone looking to upgrade their home Windows. Outstanding work with a fun personality!!"

Windows questions, answered by experts

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

When specifying window sizes, manufacturers use a standard four-digit code system. The first two numbers represent window width, and the last two represent window height. For example, a window with a code of 2917 has dimensions of 2 feet, 9 inches wide by 1 foot, 7 inches high. Windows with even dimensions include zeros as placeholders. For example, a window that is 5 feet wide by 2 feet high would have a code of 5020.

Bay windows and garden windows differ in both size and window angle. Garden windows are smaller than bay windows and extend from the house at 90-degree angles, creating a box-like shape. Bay windows, often much larger than garden windows, consist of three windows set at 25- to 45-degree angles to jut out from your home.

Storm windows are well worth the cost, especially if you live in an area that experiences extreme weather, like hurricanes, a lot of snowfall, or high winds. These windows not only help keep you and your home safe during a storm, but they can also save you thousands in storm and window damage costs.

Windows provide light and a view of the outdoors without the inconveniences that the outside world can come with, like noise, rain, snow, and unpleasant scents. Vinyl windows also provide energy efficiency thanks to their insulating properties, keeping your home at its coziest temperature no matter what season it is. They’re also excellent noise dampeners, so your interior space can stay calm and quiet.
