When you’re planning home upgrades—like new siding and windows—it can be tricky to know which project to tackle first, particularly if you’re being thoughtful with your budget. Windows and siding both make a big impact, but in many situations, starting with new windows is a smart move.
Fresh windows not only boost comfort and energy efficiency, but they also ensure your siding installation fits perfectly around them. So, if you’re deciding where to begin, window replacement is often the best first step. Let’s take a closer look at why.
Why Windows Are Generally Replaced Before Siding
New Window Installation Impacts Siding
Many window installations include installing a moisture barrier around window frames to prevent water intrusion. This barrier reaches under your siding, meaning your installer will need to cut into or remove portions of your new siding while windows are being installed. If you have siding installed before windows, your contractor may have to disturb new materials, which will cost you more money and potentially cause damage to your replacement siding.
You’ll Save Money Installing Windows First
The primary reason windows are replaced first is the capping (the protective layer around window frames that is made of aluminum or vinyl). This sheet of material is placed over your window frames, and it keeps moisture from penetrating your home. When siding is removed, capping can become damaged. If siding is replaced before windows, you’ll need to do the capping twice (during siding replacement and once more when you get new windows). It will cost you more if you replace siding before windows.
8 Factors That Impact Your Decision on Whether to Replace Windows or Siding First
1. Do You Spot Signs of Moisture Infiltration on Your Siding?
If your current siding is old and worn out, you may see signs of warping or peeling on various panels. If that is the case, replacing your siding first will safeguard your home from undergoing major problems. Once siding becomes compromised, the longer you wait to replace it, the bigger the repair needs get. It’s smart to attend to it as quickly as possible to bypass costly hassles.
2. Is Your Home’s Integrity at Risk Due to Siding Issues?
If your biggest investment’s protective layer is cracked, rotting, or missing, water can infiltrate quickly and lead to mold, rot, and insulation damage. If left unattended, this scenario can eventually lead to structural issues, compromising your house’s integrity. It’s not worth the risk to put siding replacement off. If your siding is making your property vulnerable to major issues, it’s vital you have it replaced promptly.
3. How Old Are Your Windows?
If your windows are more than 15-20 years old, it’s essential to replace them first. Today’s windows deliver exceptional energy efficiency, insulation, and protection from water infiltration. They also bolster your home’s safety from intruders, making them worth the investment.
4. Are Your Windows Drafty?
If windows have gaps that allow chilly air to seep in each winter, making your home uncomfortable and causing your HVAC unit to work harder (and wear out quicker) just to keep your house cozy, then replace them first.
5. What Type of Window Replacements Are You Planning?
Some replacement windows can be installed from your interior without disturbing your siding. This can create some flexibility for the order in which you plan your home upgrades. But keep in mind, if you’re having new construction done, it’s better to install windows first, leaving siding for the end of the build. This will allow siding to be a stunning finishing touch to your new home.
6. What Will Your Budget Allow?
If you need to choose between windows and siding, and your budget is of primary concern, window replacement is more cost-effective. New windows will improve your home’s comfort level and lower your monthly utilities.
7. Have You Reached Out to a Contractor about Your Exterior?
Working with a trusted, local contractor who can give you advice based on your home’s current condition is an essential ingredient in a successful outcome. Professional contractors can help determine what should be replaced first.
8. What Is Your Preferred Timeline for Replacement?
There’s no mystery about it; exterior upgrades affect your daily routine. So, if you want the least interruption to your schedule, have siding and windows replaced at the same time.
Depending on the number of windows you need and the complexity of your home, windows take 1-3 days to replace. Siding may take 1-2 weeks to replace, but a lot of factors affect the timeline such as the type of repairs needed when your current siding is removed. If you opt for factory-finished siding panels like Hardie’s ColorPlus® Technology or pre-primed panels, they will need to be painted after they are installed, adding several days to your timeline.
