You shouldn’t wait too long to replace windows that are old. As your home ages, the windows will become outdated in appearance, and even more concerning, they will compromise your energy efficiency and structural integrity.

If it’s time to replace a window in your home or even replace all of them, you are likely wondering about the window replacement duration. How fast is the window installation? It can take a short amount of time to install windows, though the entire window replacement timeline can take much longer.

For homeowners needing window replacement in North Carolina, Pinnacle Home Improvements is the home improvement contractor you can count on for expert window replacement and window installation. In this blog post, we discuss the timeline for the entire window replacement project and factors that could impact the duration.

Understanding the Window Replacement Process

The window replacement process will always start with an initial consultation that includes taking proper measurements, followed by selecting and ordering windows, removing old windows, and installing new windows. Here is a more detailed breakdown of the steps involved in a window replacement project:

Initial Consultation for Window Installation Process

Homeowners with old windows should first set up a consultation for a window installation with a reputable window installer. Most companies will offer this initial evaluation for free, allowing you to understand the full scope of this project and the costs associated with it. Some call this the fun part, as you will be given a choice of window frames and materials, such as vinyl windows or aluminum, when you are having a full-frame installation. Some people choose wood window frames, though these require much more upkeep over the years to prevent wood rot. Wood also needs to be repainted every few years to keep it looking pristine.

Beyond choosing the materials for your frames, you will need to decide which new windows you want for your home. Some people choose to replace windows all at once, while others do one or two at a time. When making these choices, you will need to consider whether you want double hung windows, casement windows, picture windows, or even custom windows.

Since it can feel overwhelming to make these choices, your installer will explain the advantages of each type of window and the materials to help you make the best decision. Typically, you will be given a quote during this step. You can use this quote to compare and make an informed decision about which company to choose.

Measuring by the Window Installer

After selecting a window installer to work with, precise measurements will be taken for each of the window openings. In order for an installation to go smoothly, measurements must be precise. Many homeowners try to measure new windows themselves, though few realize that they need to take them from the jamb rather than the trim.

You can measure them yourself if you want to get a vague idea of the costs you can expect ahead of obtaining quotes, but professionals will be able to make sure that every metric is considered.

Ordering Replacement Windows

Before the installation process can begin, they will need to order your windows with the proper measurements taken by the installer. After you make your selections, the windows will be ordered from the manufacturer. A reputable company will handle this step for you, keeping you informed of where they are in the process.

Removing Old Windows and Replacing Them With New Windows

Before you replace windows, the old ones must be removed. Drop cloths will be placed around all the windows to protect your flooring. Broken glass and frames will be disposed of properly, and the window openings will all be prepared for the installation. It takes about an hour to replace one window, though it will depend on the type of window installed.

As windows are installed, new flashing needs to be added to protect your home. Caulking must also be added to ensure your new windows are sealed. The finishing touches are put on to get the windows level and ensure they are installed in accordance with manufacturer requirements and local building codes.

Factors Affecting the Timeline of a Window Replacement

The steps detailed above outline the process for installing windows, though many factors can make the project take more or less time than you expect. Here is a look at what can impact the timeline of your replacement.

Complexity of the Installation

If you only need to replace a single window, the project should go quickly. However, if you’re replacing every window in your house, it’s going to take longer. It will depend on the number of windows as well as the types of windows you’ve selected. Window size can also add to the complexity. In order to get a better estimate of the time it will take to replace your windows, it’s best to ask your installer what to expect during your installation.

Availability of Windows and Installers

You might be elated to have found a window installation company you can trust, but they may not have an immediate opening to start the next day. It could be several weeks before your installation begins. Additionally, the windows you have ordered may take time to arrive. Some types are more readily available, while others, particularly custom shapes and designs, will take longer to be delivered.

Full Frame Installation

If you need a retrofit installation, it is a faster process since it only requires the installer to replace the window by fitting it into the existing opening. However, a full-frame installation requires removing part of your home’s exterior, which takes much longer. Generally, that is only required for very old windows where every part needs to be replaced, though if you have an older home, it’s a possibility you need to be prepared for.

Difficult Accessibility

Single-story homes needing replacement windows are easier to work with in most cases because contractors don’t need to climb high to access them. However, any area that is blocked by heavy foliage, is higher up, or has large furniture blocking the way on the inside can add to the complexity of the replacement, adding more time to complete it.

Window Types and Materials

The type of glass, the frame material, the style of window, and the siding on your home’s exterior may also affect the timeline for your replacement. If you choose wood frames, a contractor needs to sand, prime, and paint them first before they can be installed. Choosing vinyl frames may make the process go more quickly.

Weather

Several factors involving weather can also prolong how long it takes to install your windows. Rain can put installers at risk of slips and falls, and it can also compromise your home’s structural integrity during installation should rain get inside. Some sealants won’t bond correctly when surfaces are wet, which will cause delays in completing the replacement.

High winds are another huge concern, as they make it harder to handle materials. When windy conditions are present, your replacement may be delayed, particularly if you are having them installed on a second story or higher. Temperatures that are too hot or too cold can also impact the materials, and contractors may need more time for completion to ensure that the openings seal properly and the job is done right.

Typical Time Estimates for Replacing Single vs Multiple Windows

If you only need a single window replaced, it will usually take much less time than replacing many at once. Still, certain factors can arise that make installations take longer. If you choose a single-hung window, it might take an hour or two. Casement or double-hung windows are more complex, and even if it’s just one, it could take two to four hours.

Again, the other factors previously mentioned may be present, such as the condition of your existing frames and the need to repair siding, as well as difficulty accessing the opening. Don’t forget that your window selections will need time to be delivered, and your contractor may not be available for a few weeks.

As for multiple replacements, if you have just a few windows, typically defined as a maximum of 4, most installers can complete it in one day once they have the materials. Larger projects consisting of up to 10 windows can take a full day with a whole crew. When you’re replacing 15 or more windows, it could take up to 3 days or even more, depending on complexity and how many installers are on the team.

Whether you have a small or large project, the types of windows, how accessible they are, the structural needs of your home, and the weather may add delays. It might be disappointing to learn that there are things that need repair first, such as your siding, but taking care of it first will ensure that your windows are placed with precision, sealed, and provide protection for your home for years to come.

The bottom line is that the timeline can vary, but a reputable contractor will inform you of potential issues that could arise before they begin working, allowing you to have a better idea of when it will be finished.
