Frequently asked questions

What are the benefits of an energy efficient window?

Energy efficient windows have a lot of benefits, including lower energy bills and carbon footprints, improved temperature control, protection from UV rays, noise reduction, and reduced maintenance. They can also reduce energy costs by up to 40%.

How effective will my new windows and doors be for noise cancellation?

Low-E, argon-filled, double pane windows have better sound control than standard single and double pane windows. Dissimilar glass panes (i.e., two panes with different thicknesses) block different frequencies, making them even more effective. These types of windows can have the same sound transmission class as a building exterior or laminated glass.

What is the difference between a window replacement and a retrofit?

A full window replacement is performed when there are issues with the existing frame (e.g., wood rot), you want to improve energy efficiency, or you want to change the frame style. It involves removing and replacing the entire window frame and its hardware. A retrofit, however, only involves replacing the window sash and panes. As a result, it’s cheaper, and it’s usually done when the frame and trim are in good shape and you just want to replace the glass.

Account Manager

No Fees.
No Obligation.

We act as the marketing department for our contractor partners. Instead of spending advertising dollars on Google and Facebook, they hire us to put them in contact with clients like you.

Contractors have more time to focus on customer needs and projects rather than finding their next job. Most importantly, you get access to the best contractor for your project.
