When it's Time for Window Replacement

When old windows no longer enhance your home's architecture, protect it from the elements or filter noise it's time to upgrade windows. How do you start?

There are a myriad of factors to take into consideration. Let's break down the process to help you make your choice: style, energy use and the labeling, installation and price.

Energy Efficiency

One of the most common reasons homeowners decide to invest in new windows is to save energy. In fact replacing old, drafty windows can cut heating and cooling costs by up to 20 percent. Some people are disappointed when they discover that their energy savings do not make up the initial cost of new windows for a long period of time.

Window performance and operation should be a major consideration for any homeowner considering replacing their windows. A window that isn't functioning properly could increase home maintenance, costs for utilities, and the possibility of air infiltration or leaks. For instance windows that aren't able to move up and down or slide side-to-side correctly may require replacement because the frames have become warped or swollen due to excessive moisture caused by condensation and/or lack of proper sealing.

Another indication that windows need to be replaced is the presence of mildew or mold inside and outside the frame. This is typically a sign of failed seals or damaged weather stripping. The growth of mildew and mold that result from these issues can cause health and safety concerns for your family members if they are not addressed immediately.

New replacement windows will increase the security of your home as well as curb appeal and the value of resales. These benefits are enhanced if windows used in a renovation are energy-efficient as recommended by the National Fenestration Rating Council.

The efficiency of windows is measured by their U-factor. The lower the U factor, the greater the insulation capacity of the window. A U-factor less than 0.26 is a good rule of thumb. Besides the U-factor, other considerations for energy efficiency include frame material and design. Vinyl offers a durable, low-maintenance option, but will expand and contract as temperature changes, leading to leaks. Wood offers an elegant look and better insulation but requires regular maintenance. Aluminum is light and easy to maintain, however it is extremely heat-conductive and is a poor insulator.

To get the most benefit from replacement windows, homeowners must hire a professional contractor to install windows. A professional can help you select the appropriate windows for your home's style and climate zone, and also provide information regarding resales value and homeowner satisfaction.

Style

There's no denying that windows with new designs add to the value of a home. But when you start considering the styles, types and options available, it can become overwhelming. The choice isn't only about style or function -- choosing the wrong windows can actually detract from a home's resale value.

Window contractors have a variety of ways to replace old windows with more energy-efficient windows, based on the condition of existing frames. One of them is a pocket replacement, in which contractors take off the exterior frame but leaves the interior trim and sashes. Sash pack replacement is another method that's often recommended for older houses or areas with historic architecture where grills are needed. These are kits that come with wood or aluminum jamb liners and a replacement sash on both lower and upper halves.

The installation of a full-frame replacement window requires the removal of the existing frame and sash. This is usually recommended when the windows are damaged to the point that they're beyond repair. Full-frame windows are also recommended for homeowners who wish to change the type of window, for instance by replacing double-hungs by sliding or cases.

Search for replacement windows that bear the NFRC label. This label indicates the energy efficiency rating of the window. The higher the rating the more efficient the window is in energy use.

Before installing your new window, unlatch and take off the stops that keep the window in place. Be careful around the sill to avoid damaging the wood. If necessary you need to shim the frame. When the new window is in place then shim the top and bottom edges to ensure a tight fit. Then, apply caulk around the outside edge to seal it.

If the upvc window lock replacement you've chosen doesn't quite fit the opening, use foam-rubber backer rods to fill any gaps larger than 1/4 inches (0.64 cm). This is a much better choice than caulk, which can trap moisture and cause wood rot and mold. If your gaps are larger, you can add furring strips that measure 1 inch (2.5cm) to the existing frame. This will increase the height.

Budget

The initial cost of replacing windows is costly but it's worth it for the energy efficiency it offers and the increased comfort it provides to your home. It can also boost the value of your house and cut down on utility bills. Before you start your project, it's important to establish a budget to guide your spending decisions. Consider your household's needs for energy as well as the type of windows you would like to install. A reputable window contractor will provide insight into your expenses outside of your personal goals and provide suggestions to cut them down.

Window frame materials are one of the most important factors that influence replacement windows cost. Vinyl and aluminum are the cheapest options, while composite, wood and fiberglass frames are more expensive. Consider the benefits and drawbacks of each frame material to help you select the best option for your home. Wood windows, for instance, are more durable, provide superior insulation, but they require regular maintenance and are prone to water damage. Vinyl and aluminum windows are less expensive, however they're susceptible to rust and don't provide the same level of insulation as wood windows.

Your window replacement company may provide different methods of installation which could impact the overall cost. The most labor-intensive method is a complete frame replacement. This is where the entire existing window is removed and replaced with a new unit. This method is often advised when frames are damaged or rotted. It's also required for renovation projects that have a historical background. A cheaper alternative is to replace the insert window. During this process, the existing sash and operating hardware are removed, but the exterior trim and siding are left intact. The new window is then inserted into the opening, insulated and sealed.

When you do the work yourself, it is important to consider the cost of the tools. A caulk gun, shims that are waterproof and tape measure are necessary. Purchase shims of different thicknesses for your window sills head jambs and other heights. You'll require elastomeric sealant to fill in any gaps between the frame and casing.

Installation

Windows come in various shapes and sizes to match the architectural style of every home. There are a variety of choices, such as windows that are double-hung or single-hung sliding windows, bay, bows, casement circles, awnings, jalousie, egress and circle windows. They are also available in different materials and finishes. Some are insulated to improve energy efficiency.

If your windows are damaged, rotting or inefficient and inefficient, you can save money by replacing them with energy-efficient double-hung replacement windows. The process is fairly simple and the results are worth it. In addition to the savings in cost you will also enjoy the benefits of a brand new, beautiful window.

Before installing your new window, remove the screen and sash from the existing frame. This will make it easier to move the frame and also protect the window's materials. After the window is slid into place it's time to apply caulk along both sides of the frame and in the gap where there is any, using the recommended caulk for doors and windows.

Based on your personal preferences and the condition of your existing frame, you can choose to use either cedar or plastic shims to make sure that the window is placed correctly in the opening. Be careful not to over-shim your window as this could cause water and condensation within the frame to accumulate and cause the frame to degrade.

Your installer will ensure that the frame is level, plumb, and thoroughly caulked once the window has been put in. You can then reinstall any trim inside that was removed to fit the new window. Paint or stain the new window to match the colour scheme of your home. Be sure to seal and insulate the sill, jambs and flange on the outside of your home to further promote window performance.
