While the answer varies depending on the project scope and property type, understanding the key factors can help you plan more confidently.
For a typical installation, an experienced fitter can usually install a standard window in about 1.5 to 2 hours, which means that a skilled team could install 6–8 windows in a full working day. More complex or bespoke projects, however, may take longer, and that’s perfectly normal.
At Mumford & Wood, our precision-crafted timber windows are designed to simplify installation. Here’s what affects the timeline - and how to keep your project running efficiently.
What Can Influence Window Installation Time?
1. Quantity of Windows
- A single replacement can often be completed in a morning or afternoon.
- Full-home window installations may take two to three days, depending on access and site conditions.
2. Window Design
- Casement windows are typically easier to install due to their straightforward structure.
- Sliding Sash windows can take longer due to their weight, balance mechanisms, and finer detailing.
- Custom or oversized windows may require extra installation time to ensure a perfect fit.
3. Building Style & Condition
- Older properties often pose additional challenges, such as uneven wall openings or non-standard sizes.
- Multi-storey homes and windows in difficult-to-access areas can also slow the process, requiring specialist equipment or scaffolding.
4. Removal & Preparation Work
- Time is needed to safely remove the existing windows and assess the condition of the openings.
- If the frames or surrounding areas need repair, your installer will need additional time to complete the prep work properly.
5. Weather Conditions
- Outdoor elements play a role. Wet, icy, or extremely cold weather can impact adhesives, tools, and overall working conditions, occasionally resulting in brief delays.
What Does the Window Installation Process Involve?
Step 1: Preparation: Installers will protect internal areas, remove the old window(s), and check that the opening is ready for the new frame.
Step 2: Fitting & Sealing: Your new timber window is carefully positioned, secured, and sealed. Any required adjustments are made to ensure it opens, closes, and locks perfectly.
Step 3: Finishing Work: Internal trims are added, sealant is applied, and the area is cleaned up, leaving your new window looking as though it’s always been there.
