Installing Energy-Efficient Vinyl Windows for Milwaukee Customers

Are you considering renovations to your home? Keystone Builders Inc. in Milwaukee, a member of the National Association of the Remodeling Industry (NARI), is your choice if you value quality and experience. Upgrading to vinyl windows can improve your comfort and reduce energy costs, raise your home’s neighborhood profile and increase its value. Whether you have a mid-century modern house with nonstandard windows or want improved energy efficiency from the original builder’s installation, we have the types you need.
  • Accent or picture windows
  • Casement
  • Glass Block
  • Single-hung
  • Double-hung
  • Skylights
Vinyl refers to the type of coating on the frame. Unlike wood, it doesn’t warp and never needs to be painted. Double hung offers two sashes that usually both open. The glass block lets in light but protects your privacy. Skylights let you gaze at the stars but keep out the weather. We even offer custom-made options to meet your sizing needs. Our energy-efficient windows come with weather stripping, welded corners, insulated glass and a lifetime warranty. In business since 1954, we offer our customers only the best products.

Form Meets Function for Enhanced Performance

Going with an Energy Star-rated replacement product is an investment that can reap years of dividends. Some of the benefits include:​
  • Enhanced curb appeal
  • Reduced energy costs
  • Thermal protection for your home
  • Maintenance-free
  • Large selection of colors
Just as important as the product you select is the company you choose to work with. This is a significant, visible improvement to your home. You want a partner that will clearly explain your options, evaluate what will work best for your situation and use trained and experienced installers. Our A+ BBB rating and six decades in business reflect our deep commitment to quality and your satisfaction.
