Big Window Installation Project in Grayslake, IL


Installing windows in your home is a big step. Even though it will provide multiple benefits, having strangers working inside your home can be uncomfortable. That is also one of the many reasons why hiring a professional and trustworthy company is essential. According to IBISWorld, there are over 25,986 businesses inside the window installation industry in the United States, but you can narrow that number down with many filters, starting with location.

Hiring the right window and door installation company comes with multiple factors to consider. Some of those factors are the quality of their previous work,  the commitment they reflect, their reputation, the quality of the products they install, communication between them and the client, and how much order and safety they have with their workflow. Particularly since the Covid-19 outbreak, the safety factor has gained more importance when hiring people to work in your home.

Whether you need to replace old windows or install a new one, choosing the right company to do the job is vital, especially for your pocket. You don’t want to pay double due to a bad installation or because you got scammed.

As mentioned earlier, upgrading your windows will provide multiple benefits, especially if you get energy-efficient ones.

Selecting New Windows

We quoted them a great rate on our most popular and highest quality window – the 8000 series.

The 8000 series are double-hung windows, which are optimized for year-round comfort and energy savings. They feature an argon gas-filled chamber between the panes for insulation. The panes themselves come with three low-E coating layers to reflect heat while allowing light to pass through.

The 8000 series windows come in 6 standard interiors and 5 standard exterior color choices from white to cherry or royal brown.

If none of the standard colors are doing it for you, there is also a large assortment of designer finishes and colors to match any décor.

For this project, they chose white for the exterior.
