How Long Does it Take to Remove and Install a New Window?
When it comes to upgrading your home with new windows, one of the most common questions homeowners ask is, “How long will the installation take?”
Replacing your windows is a significant home improvement project, and understanding what to expect helps you plan accordingly.
At Phair Windows in Leicester, we want your renovation project to be as seamless as possible. Whether you’re replacing a few old windows or upgrading your entire property, we aim to make the process quick, smooth, and hassle-free.
Let’s take a closer look at the timeline for a typical window installation and what can affect how long it takes.
How Long Does a Window Installation Take?
On average, a window installation can take anywhere from one hour to half a day, depending on the complexity of the job.
This means that for a home with, say, 10 windows, the whole job might take two to three days, depending on the size of the team and the type of windows being fitted.
However, every home and every project is unique. A straightforward replacement takes less time than a complex installation that involves structural changes, unexpected issues, or bespoke frames.
At Phair Windows, we always start with an on-site survey, so our installers can give you a realistic timeframe before any work begins.
Factors That Affect Installation Time
Several key factors can influence how long a window installation can take. Understanding these helps set realistic expectations and avoid surprises on the day.
1. Number of Windows
The most obvious factor is simply how many windows you’re replacing. A single window replacement typically takes a couple of hours, but a full house replacement can take one to three days, depending on accessibility, team size, and weather conditions.
2. Type of Windows
Different styles of windows vary in complexity.
- Casement and tilt-and-turn windows tend to be quicker to install.
- Bay and bow windows, or those with custom shapes, take longer due to their structure and extra sealing work.
- Sash windows, common in period homes, require more detailed fitting to preserve original aesthetics.
3. Property Type and Accessibility
A ground-floor installation is, of course, far quicker than an upstairs or hard-to-reach window. If scaffolding or special equipment is needed, that adds time to the process. Larger properties or those with unusual designs may also take a little longer to complete.
4. Condition of Existing Frames
If your old window frames and surrounding walls are in good condition, installation will go smoothly. But if rot, damp, or structural damage appears after the old window is removed, repairs will need to be carried out first, which adds extra time.
5. Weather Conditions
Good weather is ideal for installing windows, especially in the UK, where rain and wind can sometimes cause delays. While our fitters can work through light rain, safety and quality always come first, so adverse weather may extend the process slightly.
Step-by-Step Window Installation Process
To help you picture how things unfold, here’s what the typical process looks like when you choose Phair Windows:
1. Pre-Installation Survey
Before installation day, one of our friendly surveyors visits your property to take detailed measurements and check for any issues. This ensures your new windows are made to measure and fit perfectly.
2. Preparation
On the day of installation, the team arrives and decides the most efficient order for replacing the windows.
3. Removing Old Windows
Your existing windows are carefully removed to avoid damage to the surrounding plasterwork and brickwork. Any old sealant or debris is cleaned away to prepare the opening.
4. Installing the New Windows
The new window frame is fitted, levelled, and secured into position. Our fitters check alignment, insulation, and sealing to guarantee a snug, efficient fit.
5. Finishing Touches
Once all windows are installed, we apply exterior sealant, fit any internal trim or beading, and clean up thoroughly. Before leaving, the team performs a full quality check to make sure everything works perfectly.
6. Final Walkthrough
You’ll be invited to inspect the installation and ask any questions before we leave your home neat and tidy.
How to Prepare Before Installation Day
A little preparation can help the day go smoothly and allow installers to work efficiently:
- Move furniture or ornaments away from the windows.
- Take down blinds or curtains.
- Clear access routes both indoors and outdoors.
- If you have an alarm system, notify your provider in case sensors are being removed.
These small steps can save time, protect your soft furnishings, and help your installation stay on schedule.
Quick Summary of Installation Times
| Window Type | Average Time Per Window | Notes |
| Casement | 1–2 hours | Straightforward installation |
| Sash | 2–3 hours | More detailed fitting |
| Bay/Bow | 4–6 hours | Extra structural support needed |
| Full House (8–12 windows) | 1–3 days | Depending on accessibility and team size |
