Measuring Windows for Replacement in Thornhill

Whether you are planning to replace old windows or simply upgrading to something more energy-efficient, knowing how to measure your windows properly is key. Measuring windows can seem tricky if you haven’t done it before, but with a bit of attention and care, it is quite manageable. Taking accurate measurements helps make sure the new windows fit perfectly and perform well. Doing this in Thornhill means you also have to factor in weather and building styles common to the area.

Before starting, it is good to have a tape measure, a notepad, and a pencil handy. You’ll want to measure the width, height, and sometimes the depth of your current window’s opening. Always measure the window opening from inside where you plan to install the replacement window. This is because the replacement usually fits inside the current opening rather than on the outside of the wall.

How to Take Measurements

Begin by measuring the width of your window opening in three spots: the top, the middle, and the bottom. Windows and frames can shift or settle over time, so checking multiple points helps find the narrowest spot. Use the smallest of these three numbers for your width measurement. This practice prevents ordering a window that won’t fit properly into a smaller section of the opening.

Similarly, measure the height in three places: the left, center, and right sides of the window opening. Again, take the smallest measurement to ensure the new window fits securely within the space. This careful measuring protects against issues that might appear when new windows arrive and require adjustments.

Sometimes, window depth matters, especially if you’re switching to a window with a thicker frame or better insulation. Measure from the inside edge of the wall (where the window will sit) outward to the external wall or siding. Although less commonly required for all replacements, a proper depth check guarantees the new window will not stick out awkwardly or require extra framing work.

Things to Watch Out For

While measuring, avoid including trims or decorative moldings because these do not affect the size of the window opening itself. Only the actual rough opening, the part inside the wall, is necessary for ordering new windows. You may need help removing screens or existing units if their presence makes it difficult to see the full opening.

Be aware that walls and window frames in older homes in Thornhill may have slight imperfections due to settling or warping. Taking precise measurements accounts for these little quirks. If your measurements differ by more than a quarter of an inch between points or appear uneven, it might be best to ask for professional assistance. This can prevent fitting problems after delivery.

Another important point is to measure windows in dry conditions. Wood and some frame materials can expand or contract depending on temperature and humidity. Measuring on a rainy or highly humid day might cause inaccurate numbers. Always check for any trouble spots like rotting wood or water damage during your inspection as well, since replacing windows with hidden damage may require additional work.

Choosing Replacement Windows in Thornhill

Once you have measurements ready, the next step is choosing the right style and materials for your replacement windows. Everest Windows and Doors offers a variety of options that are suited to the unique climate and homes in Thornhill. Various window styles like casement, double-hung, or sliding are available along with energy-efficient glass options that help reduce heat loss through the cold Ontario winters.

It’s wise to visit the window and door options page provided by Everest Windows and Doors to see what features might suit your needs. These options include different materials such as vinyl, wood, or aluminum frames, each with their own benefits and maintenance requirements.

You may also want to learn about the overall process of professional installation to make sure your new window will perform at its best. The information page maintained by Everest Windows and Doors offers helpful details that prepare you for what to expect during installation, so your experience goes smoothly from start to finish.

When to Get Help

While it is completely possible for homeowners in Thornhill to measure their windows by themselves, some situations call for extra help. If your windows have unusual shapes or sizes or your home has older construction with uneven openings, assistance from professionals can save time and worry. Consulting with a trusted company like Everest Windows and Doors will provide expert advice and precise measurements. They can also help with selecting the best windows that suit your preferences and local weather conditions.

Remember, proper measurement is the foundation for a successful window replacement project. When measurements are right, your new windows will fit perfectly, look great, and create a comfortable environment year-round. By following these simple ways to take your own measurements or relying on trained experts, you can enjoy the benefits of new windows in your Thornhill home for many years to come.

Types of Windows

If you are experiencing any of the problems listed above, it may be time to get new windows. But the question is, which windows are right for you? With so many to choose from, it can be difficult to make a decision.

In this section, we will review the windows that are available so that you can make an educated choice.

Awning windows lift out from the bottom of a window to open at a 45-degree angle. The angle works to protect the home from rain and other elements. They also provide the ultimate in airflow making them ideal for kitchens, bathrooms and other areas that are prone to mold and mildew due to humidity.
To ensure your awning windows are doing all they can to boost your energy efficiency while protecting your household, be sure to look for features like multi-point locking systems and fusion welded corners that will keep out water and air. A multi-chamber construction is also recommended for its ability to increase thermal efficiency, while providing insulation, durability and noise minimalization.

Casement windows have a crank that allows them to open to a 90-degree angle. The opening provides optimal airflow within interiors.
Triple sealed panes and an optimal number of internal air chambers will ensure the ultimate in energy efficiency while keeping the elements out. An advanced locking system is also recommended for providing safety and security.
casement window

Double slider windows have two panes that move along a track. They open on either side to overlap each other to let air in. They can also fully open into the house to make cleaning easy and provide ultimate air flow. Their ability to provide ventilation makes them ideal for humidity hotspots such as kitchens and bathrooms.

Sliding windows with optimal internal air chambers will be ideal for providing thermal efficiency and insulation.
single and double slider window

Double hung windows feature one pane under another. Both panes can be moved up or down on the track to allow the window to open from the top or bottom.

Double hung windows are a popular design and a favorite among homeowners. Elegant updates in recent years have made them a trendy option for homeowners. A multi-chamber construction will further provide structural integrity.

Because the windows have a flat exterior, they are ideal for patios, walkways and other areas that may be impeded by windows that open outwards.
double hung window

Single slider windows are a variation of double slider windows. Like the double slider variety, they open by sliding along their track, however, they open from one side only. If you like sliding windows, they are a more affordable option.

When low-E or low emissivity, glass is used, it results in the emission of low levels of radiant thermal energy. When combined with a krypton gas insulation, these windows can achieve optimal energy ratings.

single slider window

Single hung windows vary from double hung windows in that only the bottom pane will move when opening the window. They provide a classic style that works well in most interiors.

For the ultimate in energy efficiency, look for windows with a multi-chamber construction and an Energy Star rating.
single hung window

End vent slider windows have a fixed pane in the middle and two sliding windows on either side that move inward toward the center open. They are a good alternative to double slider windows that are better suited to smaller spaces. They also make a good option for those looking for a cost-effective alternative to casement windows.

In most cases, the middle pane will release to open inward to make for easy cleaning while letting in some much-needed fresh air.

Picture windows are stationary windows that don’t open. Rather, they are meant to let light in, provide a view and work as a decorative element within the home. They are often paired with other types of windows like fixed casement, double hung or side slider.

Get answers to your
frequently asked questions

How do I accurately measure my windows for replacement?

Measure the width from the inside of one jamb to the inside of the other jamb at three different heights: top, middle, and bottom. Use the narrowest measurement for width. Similarly, measure the height from the inside of the sill to the inside of the head jamb at three points: left, center, and right. Use the narrowest height measurement to ensure the new window fits properly.

What tools do I need to measure windows for replacement?

You will need a steel tape measure, a notepad or digital device to record measurements, a level to confirm straightness, and a step ladder if your windows are elevated. Precision is key, so avoid using cloth tapes that can stretch.

Can I measure my windows myself or should I hire a professional in Thornhill?

While it’s possible to measure your windows yourself following proper guidelines, hiring a professional ensures accurate measurements, avoids costly mistakes, and provides expert advice tailored for Thornhill’s climate and regulations.

When is the best time to schedule window installation or repair in Thornhill?

Spring and early summer are optimal for window installation and repairs due to mild weather conditions. However, scheduling can depend on your specific needs, urgency of repair, and contractor availability. Avoid extreme cold or heat for best results and material performance.

What are common types of windows to consider for replacement in Thornhill?

Common window types include double-hung, casement, sliding, bay, and picture windows. Selecting the right type depends on your home’s architectural style, energy efficiency goals, and personal preferences.

How long does window installation typically take?

Standard window installation for a single unit usually takes 2 to 4 hours, depending on window size and complexity. Full-home window replacement may take several days. Repairs are variable depending on the damage extent.

What should I expect during a window installation process?

Expect removal of old windows, preparation of the opening including checks for damages, precise fitting of the new window, insulation, sealing, and finishing. Professionals will clean up debris and ensure proper operation before completion.

How can I ensure energy efficiency with my new windows?

Choose windows with Energy Star ratings and low-emissivity (Low-E) glass. Proper installation and sealing to avoid air leaks is equally important. Consult local Thornhill climate recommendations for optimal insulation values such as U-factor and solar heat gain coefficient (SHGC).

What are signs that I need window repairs?

Signs include draftiness, condensation between glass panes, difficulty opening or closing, visible cracks, water damage around the frame, and increased energy bills. Prompt repairs prevent further damage and maintain comfort.

Do I need permits for window replacement in Thornhill?

Permit requirements vary depending on local bylaws and the scope of the work. Minor repairs usually do not require permits, but full window replacements or structural modifications often do. Check with Thornhill municipal offices or your contractor to comply with regulations.

How do I measure for window depth during replacement?

Measure from the interior wall surface to the exterior wall surface to determine window depth. This measurement helps to select windows that fit flush with wall thickness and allows for proper flashing and insulation.

What are the benefits of professional window installation versus DIY?

Professionals ensure precise measurements, proper sealing, adherence to building codes, and carry warranties. They also have experience managing unexpected issues during installation, resulting in better performance and longevity.

How to prepare my home for window installation?

Clear furniture and valuables near installation areas, protect flooring with drop cloths, and arrange access routes for installers. Inform neighbors if disruption is expected and ensure pets and children are safe and away from work zones.

What types of window repairs are commonly performed in Thornhill?

Common repairs include sash replacement, glass pane replacement, weatherstripping, frame repair, hardware adjustment, and addressing seal failures to improve insulation and functionality.

How can I find a reputable window and door installation company in Thornhill?
