We Install Marvin Windows

At MHX Designs, we understand the importance of quality, which is why we partner with a highly trusted window company — Marvin Windows. Known for their durability, beauty, and energy efficiency, these windows are an excellent choice for homeowners looking to upgrade their living spaces. With various styles and customization options available, Marvin windows offer the perfect blend of form and function.

Types of Replacement Windows

Our range of windows includes everything from practical single-hung windows to elegant bay windows. Each type of window offers distinct advantages in terms of aesthetics, functionality, and energy efficiency. During your free consultation, our window installers will help you choose the best option for your preferences and requirements.

Double-hung windows feature two sashes that slide vertically, allowing for excellent ventilation. Their classic design makes them suitable for almost any style of home, from historic renovations to contemporary new builds. Additionally, many of these windows offer tilt-in sashes for easy cleaning, making them a practical choice for homeowners. If you’re interested in a double-hung window install, don’t hesitate to contact our team!

Single-hung windows operate similarly to double-hung windows, with one significant difference: only the bottom sash moves, while the top sash remains stationary. This difference can provide slight energy efficiency improvements due to fewer moving parts and less air infiltration.

Both bay and bow windows protrude from the home’s exterior, creating a stunning visual impact and adding space to the interior of your home. Bay windows typically consist of three windows in a single frame, with a central picture window flanked by smaller windows at angles. Bow windows, on the other hand, feature four or more equally sized windows, creating a gentle, curved appearance. These windows not only enhance the curb appeal of your home but also provide expansive views and flood your rooms with natural light.

Casement windows are hinged on one side and open outward like a door, using a crank handle. They offer top-to-bottom ventilation and are known for their ease of operation. Due to the tight seal created when closed, casement windows are highly energy efficient, making them an excellent choice for homeowners looking to improve their home’s energy performance.

Sliding windows, or gliders, operate horizontally along a track, making them an ideal choice for windows above kitchen sinks or in basements. They provide ample natural light and ventilation and are available in a variety of sizes to suit different needs. Ask our window installation team about sliding windows today.

Window Replacement FAQs

The length of a window replacement project varies depending on the number of windows and the complexity of the installation. However, our team works efficiently to minimize disruption and complete the job as quickly as possible.

Absolutely. Installing energy-efficient windows can significantly reduce heat loss during winter and heat gain during summer, leading to lower energy consumption and cost savings over time.

Yes, we offer various financing options to make your window replacement project more affordable. Contact us for more details.

Replacing all your home’s windows at once is often more cost-effective and ensures uniformity in appearance, performance, and warranty coverage. It also minimizes disruption to your daily life by completing the project in a single phase. However, if budget constraints are a concern, you can have a window installer replace damaged or drafty windows now and save the rest for a later date.

You may need to invest in a replacement window if you’ve noticed the existing window is drafty, is difficult to open or close, has condensation between the panes, or has increased your energy bills. It’s also a good idea to replace any windows that are older than 10 years old to take advantage of advancements in window technology.

While spring and fall are often considered the ideal time to get new windows, you don’t have to delay your home remodeling project because we offer our window replacement services year-round!
