Installing uPVC windows can be a rewarding and cost-effective home improvement project. uPVC windows offer energy efficiency, durability, and low maintenance, making them a popular choice for homeowners. In this step-by-step guide, we will walk you through the process of installing uPVC windows, ensuring a successful installation that enhances the aesthetics and functionality of your home.
Steps to Install uPVC Windows
1. Preparation and Measurement
Before starting the installation, it is crucial to carefully check the new frame measurements against the survey size and the actual aperture sizes. The new frame should be approximately 10mm smaller than the opening to allow for expansion. Additionally, ensure that the new frame and glass are free from any obvious quality issues.
2. Removing the Old Frame
Using a sharp blade, break both the internal and external seals between the old frame and the building. If possible, remove any visible fixings without damaging the surrounding area. Once the frame is removed, clear away debris and old sealant from the opening.
3. Silicone Application
To prevent water and air leaks, carefully apply silicone along the cill up-stand and at both ends. This helps create a seal between the cill, frame, and surroundings.
4. Prepare the External Cill
Cut the external cill to size, ensuring it fits perfectly. It can be a straight cut or rebated if being fitted with projecting horns. Secure the cill end caps in place using a strong adhesive, such as super glue.
5. Placing the New Frame
Offer up the new frame and cill into the opening, using plastic packers to ensure the frame is level and plumb. Maintain an equal expansion gap around the frame to accommodate any movement.
6. Securing the Frame
Turn the frame over and secure the cill to the frame using appropriate uPVC screws. Use plastic packers between the frame and the building at all fixing points to prevent distortion when tightening the screws. Fix the frame in place, with fixings located approximately 150mm in from each corner and spaced at 600mm intervals. Avoid fixing within 150mm of any mullions or transoms. Ideally, use at least 2 fixings per side.
7. Installing the Glass
Offer up the glass and rest it on bridging packers, ensuring it is raised above the internal drainage channels. Insert plastic glass packers between the edge of the glass and the bridging packers to secure the glass in position and square it up in the frame.
8. Testing and Adjusting the Glass
Ensure the glass sits square in the frame and test the sashes to ensure they open and close correctly. Follow guidelines for “toe and heeling” the glass to avoid operational issues. If needed, insert additional glass packers in the top corner of the handle side to adjust the sash’s position.
9. Finishing Touches
Break off any excess packers, clean the frame and glass, and seal both inside and out with a silicone sealant. Apply masking tape to the frame for a neat finish and seal along the underside of the external cill. Finally, fit any trickle vents and refit the internal glazing beads in their original positions using a rubber mallet/hammer to tap them into place.
Hire A Professional Window Fitter
While the prospect of installing uPVC windows yourself can be appealing, especially if you have a knack for DIY projects, the task can indeed be quite daunting for some people. If you are unsure of your ability to handle the installation, or if you simply do not have the time or inclination, hiring a professional window fitter is an excellent option.
A professional window fitter will not only ensure that your windows are installed correctly, but they also usually include additional services within their fee. This typically costs approximately £100 per window, which can be a worthwhile investment considering the services you receive.
Firstly, the window fitter will conduct a survey of your existing window setup. This process involves careful measurements to ensure that the new uPVC windows fit perfectly into the space. They will consider any potential issues such as uneven sills or warped frames, which could impact the final result.
Once the survey is completed, the specifications are sent to the manufacturer to custom build your uPVC window. The window fitter usually manages this process, working closely with the manufacturer to ensure the window is made to the precise measurements and specifications.
Finally, once the window is ready, the window fitter takes care of the delivery process. The transportation of windows can be tricky due to their size and fragility. However, a professional window fitter has the necessary equipment and experience to handle the windows safely, ensuring they arrive at your property in perfect condition, ready for installation.
Additionally, hiring a professional window fitter often comes with a guarantee on the window installation itself. This typically lasts for three months and provides you with extra assurance on the quality and durability of the installation. Should any issues arise with the installation during this guarantee period, the window fitter is obligated to address and resolve them, usually at no extra cost.
In conclusion, hiring a professional window fitter can ultimately save you time, effort, and potential mishaps. It provides peace of mind knowing that your new uPVC windows will be installed correctly, efficiently, and with a backed guarantee, maximising their lifespan and performance.
