Replacement Window Types

Window Installation and replacement is our specialty! Whether you are looking to replace old and tired paned windows, vinyl windows, wood windows, casement windows, fiberglass windows, or aluminum windows, our professional installation techniques will have you covered no matter the type of window.

Wood Windows

Wood windows have been in use for hundreds of years. In fact, the very first window ever seen on a church was made from wood. Wood was chosen because it is flexible and can be easily cut into different shapes.

Wooden windows generally come with three panes: one large pane that acts as a vent and two smaller panes that act as insulation — this type of window is called a ‘ventilating sash’. The larger pane sits between the two smaller ones and slides up or down to let air flow through the building while still protecting it from rain and other forms of water damage.

Vinyl Windows

Vinyl windows are a type of window that is made out of vinyl, which is a soft and flexible plastic. It can be easily molded into various shapes and used to make many different types of products. There are many reasons for this choice in materials – including the fact that vinyl is strong but also lightweight, easy to work with, inexpensive, long-lasting, and durable. However, it is also not as easy to recycle; but new vinyl windows are manufactured with 95% recyclable materials. They are also more efficient than most other windows, due to their low emissivity.

Vinyl windows are usually preferred to aluminum or fiberglass-clad wood because it is easier to work with and more durable than both of these materials. Vinyl is also often less expensive than other types of windows, but this depends on the specific type of vinyl window that is being purchased. When the vinyl window has better insulation and energy-efficient features, it can also be more expensive.

Double Hung Windows

Double-hung windows are a type of window that is made up of two sashes, one above the other. These windows are usually installed in pairs or groups with each sash opening to the opposite side. They are an excellent choice for many reasons including their ability to provide great ventilation and light control. Double-hung windows also offer plenty of design options that can suit any home decor style, personality, or budget.

Double-hung windows have been around since the early 1800s but it wasn’t until after World War II that they became popular due to the increasing demand for energy-efficient buildings. Today they are still widely used because they meet LEED requirements and look great on almost all homes!

Fiberglass Windows

In contemporary times, fiberglass windows have emerged as a highly favored choice for window replacements. From designers and engineers to project managers, an increasing number of professionals endorse fiberglass for window upgrades, praising its affordability, durability, and ability to elevate both comfort and aesthetics.

Fiberglass stands out as a resilient and adaptable solution, maintaining its performance from the initial installation through the long haul. These windows offer a premium return on investment, ensuring that every dollar spent is well justified.

Storm Doors

Your front door and storm door are the focal point of your home, they are the doors that take the most abuse and most use. At Big Box stores in Northern Colorado, they carry low-quality construction-grade doors. They also like to hide pricing. The price you see on the floor is the base price, add in all the delivery, measure fee, warranty, hardware, and anything else you may need, and that low price tag became much higher in a hurry.

New Entry Doors

If you're a typical homeowner, your front door has endured numerous seasons and faced years of wear and tear. Instead of enduring another winter with an old and deteriorating entrance, consider replacing it with a new entryway. Upgrading your front façade can substantially enhance curb appeal and increase the value of your property. Installing a new door and entry system is also a simple way to give your home a more modern and appealing look.
