Types of windows to consider for your home
Choosing new windows isn’t just about style but also about function, comfort, and energy savings. Master Seal installs a full range of window styles to match any DC home, including:
Double-hung windows
These are a popular choice for traditional DC homes. Both sashes slide up and down, making them easy to clean and great for airflow.
Casement windows
Hinged at the side, casement windows open outward like a door. They offer excellent ventilation and energy efficiency.
Slider windows
Perfect for modern homes, slider windows glide open horizontally and are ideal for wide window spaces.
Bay and bow windows
Looking to make a statement? Bay and bow windows add architectural interest and extra light to living rooms or front-facing spaces.
Picture windows
These large, fixed windows frame a beautiful view and let in lots of natural light—perfect if you don’t need the window to open.
Custom shapes
Need something unique? We offer specialty windows to fit unusual sizes or design preferences.
Different homes call for different styles. That’s why we offer expert consultations to help you choose the best fit for your space, your budget, and your goals.
The benefits of new windows
Still on the fence about replacing your windows? Here’s what a new window installation can offer:
- Better energy efficiency: Modern windows with double- or triple-pane glass and insulated frames help reduce drafts and lower your heating and cooling bills.
- Improved comfort: No more chilly air creeping in during winter or heat waves seeping through in summer. New windows help maintain a consistent indoor temperature.
- Noise reduction: Live near a busy street or metro line? Quality windows help muffle outside noise, giving you more peace and quiet.
- Increased home value: Buyers love upgrades that improve curb appeal and cut energy costs. New windows can be a strong selling point.
- Enhanced security: Newer locks, tempered glass, and reinforced frames all make your home more secure.
- Easier maintenance: Today’s windows are designed to be user-friendly, with features like tilt-in sashes for easy cleaning and durable materials that resist wear.
In short, investing in window installation in Washington, DC, isn’t just about looks—it’s about long-term value, comfort, and safety.

Frequently asked questions about window installation
How long does it take to install new windows?
Most standard window installations take about 30 to 60 minutes per window. A typical home with 8–10 windows can often be completed in just one day. Larger projects or specialty windows may take a little longer.
Do I need to be home during installation?
We recommend that someone be home during installation, especially at the beginning of the project, to answer questions and ensure access. Our team is respectful, clean, and efficient, so you can go about your day while we work.
Will my home be exposed to the outside?
Only briefly. We remove and replace windows one at a time to limit exposure to the elements. Your home will stay secure and comfortable throughout the process.
What if my home is historic or has older window frames?
No problem. We’re experienced with older and historic DC homes and can recommend window types and installation methods that preserve the look and integrity of your architecture while delivering modern performance.
Do I need to prepare anything before the installers arrive?
Just a few simple steps help things go smoothly:
- Clear any furniture or decorations near windows
- Take down window treatments (like blinds or curtains)
- Disable any alarm sensors on the windows being replaced
- Make sure pets are safe and secure
We’ll take care of everything else.
Can I replace just a few windows, or do I need to do them all?
You can absolutely replace just a few. Whether it’s one drafty window in your living room or a full-home upgrade, we’ll tailor the job to your needs and budget. Many homeowners start with the worst windows and phase the project over time.
