It's time to replace your old windows if they are no longer able to protect your home from the elements, filter noise or enhance the architecture. But where do you start?
There are a lot of things to take into consideration. We'll break down the factors to help you choose: style, energy usage and labeling, installation, and cost.
Energy Efficiency
One of the main reasons homeowners decide to invest in new windows is to cut down on energy consumption. Replacing old windows that are drafty with new ones can lower heating and cooling costs up to 20%. Some people are disappointed when they discover that their energy savings will not make up the initial cost of their new replacement windows for a long period of time.
Window performance and operation are important aspects to be considered when replacing windows. A poorly functioning window can increase the cost of maintenance, energy bills, and also the risk of air infiltration or leaks. For instance windows that do not move up and down or slide side-to-side properly may need replacement because the frames have swollen or warped due to excessive moisture caused by condensation and/or inadequate sealing.
Mold or mildew on the outside and inside of the frame is another sign that it's a good time to replace your windows. This is typically an indication of a failing seal or damaged weather stripping. The growth of mildew and mold that result from these issues could create health and safety issues for your family if they are not addressed promptly.
Replacement windows can also enhance your home's security, curb appeal, and the value of resales. These benefits are enhanced if windows used in a renovation are energy-efficient according to the National Fenestration Rating Council.
The U-factor is a measure of the energy efficiency of windows. The lower the U-factor, more insulating power the window is. A U-factor that is less than 0.26 is an ideal rule of thumb. Other than the U-factor aspects to consider when evaluating energy efficiency include frame material and design. Vinyl is durable and low-maintenance, however, it is prone to contract and expand as temperatures change. This can cause leaks. Wood is classic and provides better insulation but requires regular maintenance. Aluminum is light, easy to maintain, and it conducts heat efficiently.
To get the best results, homeowners should work with an experienced window installation professional to ensure that replacement windows are installed correctly. A professional can assist you in selecting the best windows for your home's style and climate zone, and can provide you with details on the resale value of windows and homeowner satisfaction.
Style
New windows will always add value to a home. It isn't easy to look through all the various types, styles and configurations that are available. The choice isn't only about style or function -- choosing the wrong windows could detract from a home's resale value.
Window contractors use a variety of ways to replace old frames with more energy-efficient ones depending on their condition. A contractor can replace the frame on the outside by a pocket replacement. The interior trim and sashes are left intact. Another option, usually suggested for older homes or older areas with strict requirements for grilles, is a sash pack replacement. These are kits that come with aluminum jamb or wood liners and a replacement sash for the upper and lower halves of the window.
A third method is to install windows with a full frame, which require removing the entire existing frame and sash. This is recommended when the existing windows are beyond repair. Full-frame installations are also recommended when homeowners want to change the type of window, such as by replacing double-hungs by sliding or cases.
Search for replacement windows that bear the NFRC label. The label identifies the energy-efficiency rating of the window. The higher the rating the more efficient the window.
Before installing your new window, loosen and remove the stops that hold the window in place. Work with care around the sill to avoid damaging the wood. If needed, shim the frame. Once the window has been installed, shim both the bottom and top edges to ensure a snug fitting. Apply caulk to outside edge of the window to ensure it is sealed.
Fill any gaps greater than 0.64 cm (0.24 in) with foam-rubber backing rod. This is a better choice than caulk, which can trap moisture, leading to wood rot and mold. If your gaps are wider then you can add furring strips of 1 inch (2.5cm) to the frame. This will increase the height.
Budget
Window replacement is a significant investment however the energy efficiency and improved home comfort it provides makes it well worth the initial cost. It also improves the value of your home and can help lower your utility bills. It is essential to establish a budget before you begin your project to guide your choices. To help you determine the appropriate amount, take into consideration your household's energy consumption and the type of windows you'd like to install. A reputable window contractor will provide insights into your costs outside your personal goals and make suggestions to minimize them.
Window frame materials are one of the most important factors that influence replacement windows cost. Vinyl and aluminum are the most affordable alternatives, whereas wood, fiberglass and composite frames are more expensive. Consider the advantages and disadvantages of each type of frame to help you determine which one is the best fit for your home. Wood windows, for example, are more durable, provide superior insulation, but they require regular maintenance and are susceptible to water damage. Vinyl and aluminum windows are less expensive, however they're susceptible to rust and don't offer the same level of insulation as wood.
Your window replacement service will provide a variety of installation techniques that impact the your overall cost. The most labor-intensive method is a complete frame replacement. This is where the entire window is removed and replaced with a new unit. This is usually recommended if the frames are damaged or have rotted. It's also required for historical renovation projects. Insert windows is a cheaper option. During this process, the existing sash and operating hardware are removed, but the exterior trim and siding are left intact. The new window unit will be inserted in the opening, insulated and sealed.
If you are doing the work yourself, it is important to take into account the cost of the tools. A caulk gun, shims that are waterproof and a tape measure are essential. Buy shims of various thicknesses for window sills, head jambs and other sizes. Also, you'll need caulk made of elastomeric to fill in any gaps between the frame and casing.
InstallationWindows come in various shapes and sizes, to fit the architectural style of every home. Options include single-hung, double-hung sliding bay bow, casement circle, garden, awning, jalousie and egress windows. These windows are available in different materials and finishes. Some are insulated to improve energy efficiency.
Replace your old, inefficient windows with energy-efficient double-hung windows to save money. The process is easy, but it's worth the effort. You'll also reap the benefits of having a beautiful, new window.
Before installing your new window, remove the screen and sash from the current frame. This will ease the manipulation of the frame and prevent any damage to the window's materials. After the window is moved into position, you'll need to apply caulk around both sides of the frame and around the gap, in the event that there is one, use the caulk recommended for doors and windows.
You can choose to use shims made from plastic or cedar according to your preference and the condition of the frame. This will ensure that the window is seated correctly in the opening. Be careful not to over-shim the glass window replacement, however, as this may cause condensation and water to build up inside the frame and cause damage to the material.
After the window is set the installer will make sure the frame is level, plumb and caulked thoroughly. You can then put back in any trim inside that was removed to make room for the new window. Paint or stain the new window to be in keeping with the color scheme of your home. Be sure to seal and insulate the jambs, sills and flange on the outside of your home to enhance the window's performance.
