Why Replace Your Windows?

Energy Efficiency

Energy Efficiency

​By installing windows with low-e coatings, your windows will now block 99.9% of uv rays, reject thermal rays before they can make the room feel super-heated, and protect your floors, furniture, and artwork from bleaching. We also recommend utilizing argon/krypton gas to fill the glass pack. These gasses are denser than air, acting as insulators to keep our air conditioning inside our homes.

New windows significantly reduce external and unwanted noise to allow a quieter existence inside your home. Most windows, original to the home, often have balance failure, which can make operating the windows difficult or non-operational. Window replacement will ensure ease of use, guaranteed operation, and upgraded balance system technology for years to come.



Wilco windows are not only made to be looked through but also to be looked at. Bring back sharp visibility and solidly constructed frames to add finishing touches to your home. No more “fogginess” due to condensation or discolored glass or frames due to harsh UV rays and mineral deposits. Our knowledge can help you express your design creativity.


How Much Can You Save?

Take your highest utility bill in the summer, subtract your lowest bill in the winter, and you can typically save 40% on that number.

Calculation developed by the window industry when you upgrade from a single panel aluminum window to a modern energy efficient unit.

There Are Four Primary Materials Used in Frame Construction, and each has unique Considerations

Aluminum Frames

Aluminum is strong and lightweight, allowing for a narrower frame with clearer glass. Modern, thermally broken aluminum windows offer a sleek, contemporary style, especially in the darker color options.


Aluminum used to be the most cost-effective option for replacement windows. However, to meet energy guidelines for most big cities, aluminum windows need to be thermally broken. This process involves bifurcating the frame, injecting it with resin, and reassembling it. This negates any cost savings and makes the window more expensive than a typical vinyl offering.

Vinyl Frames

Vinyl is extremely energy efficient, low maintenance, and affordable. This is why 85% of our clients choose a vinyl window package. It offers the most flexibility around style and customization in the market, whether specialized shapes, sizes, or operational detail.


While vinyl is thermally inert and highly energy efficient, the frames must be thick to build them strong enough. Some homeowners notice a loss of clarity in the glass when transitioning to a vinyl package.


Fiberglass/Composite is reputable for its strength. Being 11x stronger than vinyl allows for a slimmer frame design with clearer glass. Large sizes are easily accommodated with energy efficiency comparable to vinyl—dark color pallet options, with color through the product versus painted.


Cost is on the high end and style availability is limited. Special shapes can be difficult to manufacture.

Wood Frames

Who doesn’t appreciate the look and feel of real wood? The color options are endless, whether you prefer paint or stain. There is low exterior maintenance, great hardware selections, and durable, energy-efficient options.



Cost. Retrofitting presents challenges and requires interior trim and the loss of sills.
