Double hung windows are a popular choice for homeowners due to their versatility, ease of use, and the possibility of improving air circulation in the house. This article aims to provide a comprehensive analysis of double hung windows and guide potential buyers through the installation process.

What are Double Hung Windows?

Double hung windows have two sashes (the part that holds the glass in place) in the window frame that move up and down independently. This design provides flexibility as you can open either sash according to your needs. The upper sash can be opened to let hot air escape, while the lower one can be opened to let cool air enter.

Advantages of Double Hung Windows

  • Ventilation: With two operational sashes, double hung windows offer improved ventilation. As warm air rises, you can create a natural flow of air by opening the top sash slightly.
  • Easy Cleaning: The ability to tilt both sashes inward makes cleaning easy, especially for second-story windows.
  • Versatility: Double hung windows fit most architectural styles from traditional homes to modern designs.
  • Energy Efficiency: When closed, double hung windows form a tight seal, preventing heat or cool air from escaping.

Installation Process

The installation process for double hung windows involves multiple steps:

  1. Measurements: Proper measurements are crucial for window installations. Measure the height, width, and depth of the window opening.
  2. Ordering: Choose your desired style and order your replacement double hung window according to your measurements.
  3. Removal of Old Window: Carefully remove the old window without damaging surrounding areas.
  4. Installation of New Window: Place new window into open space ensuring it is level before securing it in place with nails or screws
  5. Insulation & Sealing: Apply insulation around all gaps and then seal the area with caulk.
  6. Installing Trim: Finally, install the interior and exterior trim.

It is highly recommended to hire a professional window installer if you are unfamiliar with the techniques and safety procedures associated with window installation. Despite the extra cost, this ensures a flawless finish and appropriate fitting of your double hung windows.

Double hung windows are an excellent choice for those looking for a blend of functionality and traditional style. By understanding what they have to offer and how they are installed, homeowners can make an informed decision when updating their windows.


Slider windows, also referred to as gliding windows, are a popular choice among homeowners for their simplicity, modern style, and space-saving design. This type of window opens horizontally, sliding along the window frame’s length. They are an excellent option for areas where you may have limited vertical space but plenty of horizontal space.

Features of Slider Windows

Here are some noteworthy features that make slider windows an attractive choice:

  • Ease of Use: Slider windows are incredibly easy to operate. They slide open from side to side, making them perfect for areas hard to reach or where lifting would be difficult.
  • Great View: Since slider windows typically have fewer muntins (the strips separating panes), they offer a larger unobstructed view compared to other types of windows.
  • Efficient Ventilation: As they can be opened half their width, slider windows provide excellent ventilation.
  • Durable: With fewer moving parts than conventional designs like double-hung or casement windows, slider windows usually have longer lifespans.
  • Energy Efficient: Many contemporary slider windows come with energy-saving features like double glazing and Low-E glass coatings that reduce heat transfer.

Installation Process for Slider Windows

The installation process for slider windows can vary depending on factors such as the existing window size and framing condition. However, here is a general step-by-step guide:

  1. Measurement: The first step is to accurately measure the existing window opening to ensure your new window will fit perfectly. Always measure width at three points: top, middle and bottom; height at two points: left side and right side; then use the smallest measurements.
  2. Removal of Old Window: Remove the old window carefully without damaging surrounding structures.
  3. Prepare the Opening: Clean out any debris in the opening area and repair any damage to the frame or sill.
  4. Window Installation: Carefully lift the new window into place, ensuring it sits snugly into the opening. It should be level and square in the opening.
  5. Securing the Window: Once positioned correctly, secure your window using screws through the jamb. Be sure not to overtighten them as it could warp the frame.
  6. Sealing: To ensure your window is weatherproof, use a high-quality exterior-grade caulk around the window’s perimeter.
  7. Interior Finishing: Finish up by installing trim around your new window on the inside of your home if required and patch up any gaps with foam insulation.

Though this process may seem straightforward, for best results, you may want to consider hiring a professional installer who has experience with slider windows. Professional installation will not only ensure that your windows are installed correctly but also validate any warranties provided by the manufacturer, maintaining their value over time.


Slider windows, also known as gliding windows, are a great addition to any home. They are trendy, aesthetically pleasing, and offer effortless operation. This guide will take you through the key features of slider windows and provide you with a comprehensive guide to their installation process.

Features of Slider Windows

Slider windows have several key features that make them popular among homeowners. These features include:

  • Easy Operation: Slider windows glide along a track and require little effort to open or close. This makes them an excellent option for areas where accessibility may be an issue.
  • Great Ventilation: With slider windows, you can open half of the window area for ventilation. This is more than double-hung or casement windows where only part of the window opens.
  • Wide Views: Since slider windows do not have a vertical sash in the middle like double-hung or casement windows, they offer wide uninterrupted views.

Installing Slider Windows

The installation process for slider windows can be broken down into several steps:

Step 1: Preparing for Installation

Before starting the installation process, it’s necessary to prepare your work area. Remove any curtains or blinds from your existing window and clear the area around it. Measure your window opening to ensure your new slider window will fit.

Step 2: Removing Old Window

Use a utility knife to cut through any paint or caulk around your existing window. Remove any screws holding it in place and carefully lift it out of its frame.

Step 3: Preparing The Opening

Once old window is removed, clean up the opening by removing any debris or old caulk left behind. Check if the opening is square by measuring diagonally from corner to corner in both directions; if measurements are equal then it is square.

Step 4: Installing The New Window

Place new slider window in the opening and make sure it’s level by using a level. Once leveled, secure it into place by screwing it to the frame.

Step 5: Sealing The Window

Apply a bead of caulk around the exterior of the window to seal it against weather and drafts.

Step 6: Finishing Up

Install any necessary hardware provided with your slider window. You can then put back your curtains and blinds.

Considerations During Installation

During installation, keep in mind that:

  • Proper measurement is crucial for a successful install. If the window doesn’t fit properly, you may face issues with sealing and insulation.
  • Always check if the installed window operates smoothly before sealing it.
  • Hiring a professional for installation may be a good idea if you are not comfortable doing it yourself.

By understanding these features and following this guide, installing slider windows can be an effortless task. Whether you opt to do it yourself or hire a professional, rest assured that you are making an excellent choice with slider windows. They will not only improve the overall aesthetic of your home but also provide great ventilation and unobstructed views.

Bay and bow windows are a beautiful architectural feature that can add light, space, and character to a home. These windows extend outward from the home’s exterior wall, creating an appealing visual interest from the outside and adding extra living space on the inside. However, installing these types of windows requires some special consideration. This guide will provide a comprehensive overview of how to install bay and bow windows in your home.

The installation process for bay and bow windows involves three main steps:

  1. Preparation
    Before you begin, it’s important to measure the window opening accurately. This will help determine the size of window you’ll need, as well as any additional materials required for installation. You should also prepare any necessary tools at this stage – including a drill, level, tape measure, screws, shims and caulk.
  2. Installation
    The first step in the installation process is to secure a support system for the window since bay and bow windows are heavy due to their size and construction. These systems can include cable support systems or knee braces that provide structural integrity. After securing the support system, it’s time to install the window itself into the opening. It’s crucial to make sure that it’s level because an improperly installed window can lead to problems down the line such as leaks or difficulty in operation.
  3. Finishing Touches
    Once your new window is securely installed, you’ll want to add finishing touches like trim or moulding around the interior of the window to give it a clean finished look.

Installing bay and bow windows aren’t simple DIY (Do It Yourself) tasks due to their size, weight and complexity involved in installation process; hence professional help is often recommended. Here are some factors that affect cost when hiring professionals:

  • Size: Larger windows require more labor and materials hence tend to cost more.
  • Location: If the window location is hard to reach, this can increase labor costs.
  • Window type: Bay windows are typically less complex and cheaper to install than bow windows.
  • Old Window Removal: The cost to remove and dispose of old windows can also affect the overall cost.

Bay and bow windows are a wonderful addition to any home, enhancing its aesthetic appeal and value. Their installation, while complex, can be made smoother with careful preparation and by hiring experienced professionals. Lastly, remember that quality materials are key in ensuring a successful installation and long-lasting results.
