Windows
Most people don’t often think about the windows on their home, yet can you imagine your home without them?
While the windows on your home should ultimately provide natural light, energy efficiency, and protection from the elements, they do much more. The fact of the matter is, a home with beautiful windows stands out. When you look at a home, your eyes are likely immediately drawn to its windows.
Get A QuoteBenefits of Window Replacement
Since window replacements offer a wide variety of benefits homeowners are putting this at the top of their priority list.
Ventilation
Proper air ventilation functions similarly to our lungs, moving clean air in and bad air (such as moisture, pollutants etc.) out. Without this circulation moisture can create mold and mildew which can lead to serious health issues. For example, an open kitchen window can allow smoke from cooking to escape just like an open bathroom window allows moisture (steam) to be released so it doesn’t stick to your walls and ceilings.
According to the Environmental Protection Agency (EPA), every year, a six room home collects an average of 40 pounds of dust containing up to 45 toxic chemicals. In fact, indoor air quality is 2-5 times more polluted than outdoor air.
Natural Light
Windows provide natural light and connect the indoors to the outdoors. According to a study performed by Building Technology Innovation, because natural light makes spaces look bigger, people are typically willing to pay more for a home with ample natural light.
Mental Health and Well-Being
Studies have shown that natural light has a positive effect on our overall health and well-being. Windows make us feel less confined, which has a direct effect on our mental health. In addition, natural light can also boost the production of Vitamin D and the release of serotonin, a natural antidepressant and mood enhancer.
Physical Health and Well-Being
Advances in modern technology have led to innovative window designs. Many windows now help prevent the accumulation of dust and allergens which can have an impact on our physical health.
Energy-Efficiency
Replacing old windows is one of the easiest ways to reduce energy usage. Strategic natural light can help reduce energy costs because it can brighten a space without using electricity. Many window brands have introduced energy efficient windows with airtight seals that help maintain your home’s temperature, help save on utility bills and reduce your carbon footprint.
Security
Without functioning windows, your home could be at risk for unwanted intruders, including thieves, insects and pests. Advances in technology have produced windows that contain advanced closing mechanisms meant to prevent break-ins. Older windows can be unlocked easily, making it easier for someone to enter your home.
Safety
Windows are now being manufactured to provide safety benefits if broken. Windows with tempered glass are designed to break into small, granular chunks instead of splintered shards to reduce the chance of injury. Laminated glass windows contain a polymer that holds the glass together if broken, which offers added protection against intruders.
Protection
When water leaks into a home, it will create mold and mildew growth. When not treated, this can lead to a host of problems. Replacing the windows in your home will help prevent unwanted water or moisture from seeping in, helping to keep your home, family and valuables safe.
Noise Mitigation
Windows serve as a sound barrier between the interior of your home and the outside. Many window manufacturers are producing windows designed to help reduce outside noise. However, the amount of noise reduction will depend on the window type, quality and installation.
Sustainability
Modern windows with advanced technology will increase sustainability. These innovations can reduce the time spent cleaning because they help prevent the accumulation of dust and allergens.
Value
Replacing the windows on your home may be one of the most cost-effective home improvement projects you can do. If you are looking to sell (or rent) your home, new windows will almost certainly boost its value. A well-maintained window should last 20-50 years and help to protect your most valuable investment - your home.
Curb Appeal
Windows have a primary purpose, to provide a great view. Older (or failing) windows eventually become discolored or damaged over time which can result in a distorted view and tired appearance. New windows can boost your home’s curb appeal and make your home stand out.
Variety
Modern windows come in a plethora of styles and offer features that can help make your home more functional and appealing. Windows are now available in virtually every shape, size and style with features designed to offer long-term benefits.
Maintenance
As with everything else in your home, all windows require upkeep. However, high quality modern windows dramatically reduce the amount of maintenance your windows require, saving you both time and money.
Ultraviolet (UV) Exposure
Modern windows are now available with tinted glass to reduce UV exposure. In fact, some manufacturers have produced windows that block up to 94% of the sun’s ultraviolet light which can help prevent interior paint and furniture from fading.
Warranty
Most new windows come with some sort of warranty benefit. Older windows typically are not under warranty. Warranties will vary depending on the manufacturer and type of window.
Anatomy of a Window
While it is important to understand the types of windows available, it is equally important to understand the components that make them up.
The following helpful information describes various window components and their functions:
Apron:
The horizontal trim underneath the window sill.
Balances:
The mechanisms that counter-balance the sashes (typically spring loaded) so the sashes are easier to open and close.
Casing:
The decorative framing around a window that covers the space between the window and the wall.
Corbel:
A decorative support (bracket) jutting out from the wall (commonly found on oriel-style windows).
Frame:
The framework surrounding the perimeter of a window to keep it in place.
Glazing:
Another word for the glass in the window covered with a translucent coating to help manage the amount of light and heat penetration.
Grille (Muntin):
Decorative cross pieces that divide the window into panes to create a grid-like appearance
Head:
The horizontal piece that forms the top of the window pane.
Jamb:
The pieces that form the top, bottom and sides of the window head.
Mullion:
Vertical pieces that separate sections of glass on a window
Pane:
A plate of glass within a window frame.
Rail:
The horizontal part of a sash.
Sash:
The part of the window that moves up and down to open or close the window.
Sill:
The piece that runs along the window frame.
Stile:
The vertical part of the sash.
Stool:
The bottom horizontal shelf attached to the window sill where the sash descends (where plants and/or decorative items can be placed).
Well (Below Grade):
The area (typically a rectangle or half circle) that sits outside an egress window for protection.

Window Frames
A window frame is the stationary part of a window that is installed directly into the walls of a home. The frame encloses the window on all sides in order to hold the entire window in place. Proper installation is vital in order to prevent damage (or breakage) to the window panes. A window frame that is installed too loosely can allow water/moisture to seep in and penetrate the interior walls of the home. A window frame that is installed too tight can eventually dislodge the window panes as the window frame contracts over time.
Wooden window frames can be matched to an existing wood trim and are typically found in older homes.
Wood Window Frames

When Should Windows Be Replaced?
One of the most common concerns homeowners express is not knowing when to replace the windows on their home. There are several common issues that can indicate it may be time to replace your windows.
Increased Utility Usage
If you’ve noticed an increase in utility usage, it can potentially indicate that your heating and cooling system is working harder to maintain your home’s temperature because windows need to be replaced.
Condensation
Moisture accumulation inside of a window can indicate that the window seal is beginning to fail. The moisture typically presents itself between the window panes and can lead to a multitude of problems, including mold, increased energy consumption and leaks.
Fogging
Special seals hold windows in place and can eventually harden and crack (especially with vinyl window frames). When the window frame expands and contracts with fluctuating temperatures, it can lead to fogging.
Drafts
A draft may indicate that your windows are not insulating properly. This means that air is escaping and entering the home, which will impact energy consumption and can lead to leaks and a plethora of other problems (including the ability for insects and other pests to infiltrate your home’s interior walls).
Peeling
If you notice paint beginning to peel around your windows’ exterior, it can indicate that water has become trapped beneath the surface. This often leads to rot, mold and mildew forming in hidden crevices, which is a definitive indication that the windows should be replaced.
Decreased Function
If your windows have become difficult to open and close, it’s important to determine the cause. Decreased function can result from a number of issues, some of which are easily remedied (such as hardware replacement). Alternatively, it can indicate that the frame has rotted, which can lead to a multitude of issues if not addressed.
Considerations
Window replacement is a long-term investment. The type of window you choose will depend on a variety of factors, each of which are equally important.
Purpose
The windows in your home should not only boost your home’s curb appeal, but offer energy efficiency, comfort and safety. Before choosing a specific type of window, it’s important to consider the requirements of the space itself.
Moisture Barrier
Make sure there is a moisture barrier in the crawl space under your home. The ventilation will help prevent moisture from being trapped, which can impact your home's structural integrity.
Window Sealant
The sealant used to help windows function properly can eventually harden and crack. When the window frame contracts and expands from temperature fluctuations, this can cause the window to crack or break.
Damage
Windows that have not been installed or maintained properly should be assessed regularly for damage. This could indicate that some, or all windows need to be replaced or repaired.
Quality
Economy windows tend to be of lesser quality, which can have a direct impact on its lifespan. In addition, economy windows tend to lose their seal within the first few years, which can lead to condensation and operational issues.
Installation
Windows that have not been installed properly almost always lead to problems. Poor installation can result in hidden problems such as gaps where water can become trapped, leading to rot and mold.
Window Replacement
Your windows endure continuous exposure to the elements. Did you realize that your home's windows play a vital role in insulating your living space? Windows directly affect insulation as they represent openings in the structure of your home.
One of the most common concerns for many homeowners is trying to figure out when it’s time to replace the windows on their home. In fact, many homeowners have no idea how old their windows are.
Regardless of how old the windows in your home are, issues can pop up at any time.
If your home is starting to feel colder in the winter and warmer in the summer, you notice persistent drafts, or if your windows feel cold to the touch in cooler weather, it may be time to replace your windows.
Common Indicators That It May Be Time To Replace Your Windows Include, But Are Not Limited To:
- One or more of your windows have become difficult to open or close (especially windows with wood frames.)
- You feel drafts (cold or warm air coming in around the window frame.)
- You can hear the wind whistling.
- Light can be seen through gaps in the window frame.
- Your energy consumption has increased.
- Condensation/moisture accumulation on the inside of a window (especially if you notice moisture pooling on the windowsill.)
- Noise (older windows don’t offer a lot of sound insulation while modern windows are made to absorb sound.)
- The unique seals securing double panes tend to harden and develop cracks over time, a consequence of the frame expanding and contracting due to temperature fluctuations.
- Improper installation (many unqualified contractors use incorrect measurements or install a window not made for the particular opening or a window of subpar quality, which eventually results in the infiltration of wind, pests and water.)
- Decaying window frames (exposure to moisture can result in rot and in some cases, the growth of mold.)
Reducing the amount of air that can leak into or out of your home is a great way to lower your monthly heating and cooling costs and can increase your home’s comfort.
There are many factors that impact a window’s insulation properties:
Window Frame Material
The materials of a window frame play an important role in its insulation properties. For example, vinyl frames offer better insulating properties versus wood, which can rot over time, especially if exposed to moisture. In addition, the wood can warp, due to fluctuations in temperature which can also make the window harder to open and close.
Glass
The insulating properties of a window are significantly influenced by the type of glass used. For instance, single-glazed/paned windows are less effective at insulation compared to double or triple-glazed/paned windows because they lack the capacity to incorporate an air layer between the glass sheets. This air layer serves as an additional barrier to heat transfer.
Seals/Weatherstripping
When windows are properly sealed, they prevent air leakage which helps to insulate. Weatherstripping enhances the sealing because it seals off any gaps between the window and the frame.
Window Coatings
Windows with ‘low-E’ (low-emissivity) improve insulation because they reflect heat radiation. This reduces the need for additional heat because the heat is not able to escape the home.
Double or triple glazed/paned windows with low-E coatings can reduce heat loss by 70% versus single pane windows.
Implementing the following tips to seal air leaks and enhance insulation can contribute to reducing heat flow through your home, but it's important to note that these are not long-term solutions and won't yield the same results as having your windows replaced and installed by a licensed professional such as Honey Do Men:
- Caulk and weatherstrip any doors and windows that leak air.
- Have foam gaskets installed behind outlets and switch plates.
- Replace single glazed/paned windows with more efficient double or triple glazed/paned, low-E windows.
- Caulk and seal air leaks where plumbing, electrical wiring or ducting comes through walls, ceilings, floors and soffits over cabinets.
- If you notice discoloration on your ceiling paint and carpets, it may indicate air leaks on wall/ceiling joints or wall/floor joints.
- Replace your exterior door thresholds with ones that have pliable sealing gaskets.
- When your fireplace is not in use, make sure the flue damper is closed tightly.
- Use foam sealant on gaps around baseboards, windows or anywhere air can leak out.
In short, if it’s time to replace your windows, the investment will likely result in big savings on your monthly energy bill.
Depending on the type of window (and proper installation), a window will typically last 20-50 years. While many economy windows come with lifetime warranties, they are of lower quality because they are mass produced in standard sizes.
