Should I Replace Windows & Siding At the Same Time?

Both windows and siding are susceptible to various issues over time, often necessitating replacement. If you’re considering refreshing your home’s appearance with new windows and siding, it’s essential to contemplate both window replacement and siding installation. Pairing these upgrades ensures that your home’s aesthetics harmonize, resulting in a cohesive overall look.

Simply, the answer is yes 

Aesthetically, replacing your windows and siding at the same time is a great idea. In this manner, both design aspects contribute to the overall aesthetic. Sleek and beautiful windows surrounded by faded and battered siding are not an ideally good match. It is recommended to replace these pieces all at once to keep them appearing coherent. On a more practical level, this is also true. Jointly replacing windows and siding helps your contractor to properly lay the capping around your windows before installing your new siding. This is important because capping is a construction process in which a sheet of aluminum or vinyl is fitted over the external frames of your windows. This creates a moisture barrier that strengthens the seal between your windows and the wall, protecting the interior of your home against leaks and water damage. When done correctly, window capping can also help to extend the life of your siding by directing water away from the exterior.

The sequence of installation

When window capping is installed beneath the window frame, it extends beneath the siding as well. As a result, the ideal sequence for these tasks is to replace the windows first, followed by the siding installation. By getting new replacement windows first, you’ll prevent potential damage to your new siding later. To install windows, your contractor has to install a moisture barrier that goes around the window and that barrier needs to go behind the siding as well. That means the contractor might have to cut into your new siding to do that or remove the siding and reinstall it after. In the case that you are unable to take on both significant projects at the same time due to budgeting or other foreseeable reasons, you should consider prioritizing the windows first. Since contractors usually install the windows before the siding, you will still be following the best project sequence. However, if your siding is seriously damaged to the point of posing a safety or security issue, you should address it right away. Dented, decaying, or hole-filled siding will not benefit your energy efficiency or weather protection. By contacting a professional and reputable contractor, you may avoid future issues.

Improving the energy efficiency of your exteriors through multiple projects 

Another reason to replace your windows and siding at the same time is that they can both have an impact on your home’s energy efficiency. Windows, in particular, can prevent conditioned air to escape via the frames and joints, while siding serves as a protective layer against extreme heat and cold. When seeking to preserve energy, your efforts must be a whole-home endeavor. If air and moisture are entering your home through cracks in your siding, it is not ideal to replace your windows with energy-efficient Low-E glass windows because its benefits will not be utilized.

A siding replacement also provides a chance to increase the insulation of your home. Rigid foam insulation and housewrap put beneath vinyl siding can increase the R-value of your walls, making you less susceptible to drafts and varying weather conditions. This, along with better-performing windows, may dramatically lower your energy costs, especially if you live in a location with harsh summers or severe winters.

Preparing your house for greater energy performance may necessitate a number of adjustments, but the savings on your energy costs will more than compensate. If you truly want to improve your home’s energy efficiency, you should contact a professional energy auditor. They may assess various components of your property and advise you on what to replace and which concerns are the most critical. After all, any home improvement is an investment and this way you can ensure you are getting the most out of your time and money.

Windows are essential for both keeping your home aesthetically appealing and weathering out any storm. There are some signs to look out for when you need a window replacement. Such signs may include, windows rattling when it is windy outside or you feel your home becomes drafty with warm air in the summer months or cool air in the winter months. Other signs to look out for are excessive condensation on your windows or they become fogged. In the case that they are no longer functioning as intended and you need to prop up your windows open because they can not stay open on their own. All are telltale signs that a window replacement is recommended.


The siding of your home can set you apart from your neighbors as well as function as a protective layer from all kinds of weather conditions. Through the years your siding can experience a great deal of wear and tear and there are a few signs to look out for that may indicate you need a siding replacement. Such signs may include, your current siding looks weathered and constantly needing new paint, or the current siding has extensive insect damage or dry rot.

Siding and windows have an effect on the overall structure of a home. They protect the inside from weather damage and improve a property’s curb appeal, which can increase its resale value. The majority of homeowners repair their siding and windows at the same time because it enhances efficiency, convenience, and curb appeal. It can be preferred to replace both windows and siding because homeowners only have to deal with one contractor. When you upgrade both your windows and siding at the same time, you will save time and money.
