Ultimate uPVC Window Installation Checklist: What to Check After Installation
Installation of uPVC windows is a planned process that takes place in stages. The installation team handles most of the technical work, but homeowners should be aware of what to look for on installation day to ensure everything goes smoothly.
This list provides homeowners with guidance on what actions and inspections to conduct during the uPVC window repair process. These checks ensure the windows are operational and installed correctly.
Preparing the Site
The area is checked and cleaned to make sure the windows fit properly before they are put in. Workers protect the areas around them while they drill and fit by covering them.
This early work helps things go smoothly during the installation.
What homeowners should look for:
- There is no trash in the window openings
- Nearby surfaces are safe
- Check the measurements before you start working.
Frame Placement and Alignment
Before the uPVC window frames are permanently attached, they are positioned within the apertures. Now, the frame’s alignment is checked to make sure it is straight in the wall.
Ensure that the frame is level on all sides. At this point, you can make any changes you want before the frame is permanently attached.
What homeowners should look for:
- The frame looks level and straight
- No tilt or slant can be seen
- Before drilling, check the alignment
Fixing the uPVC Window Frame
Fasteners secure the frame in place once it has been properly positioned. These fasteners are used in a few places along the frame to hold it in place.
People who own homes can tell if the fixing was done evenly and not just at the corners.
Things that homeowners should look at:
- A lot of fixing points have been used
- The frame feels strong and safe.
- No wobbling after fixing

Sealing Space Between the Frame and Wall
After the frame is in place, the space between it and the wall must be sealed. Sealant is used to fill in holes and keep water and air out. Sealing that isn’t even or is broken can hurt how well it works over time.
Things homeowners should consider:
- All the gaps are filled in
- The sealant looks neat and smooth
- There are no more open holes
Gasket Slots and Drainage Slots
Homeowners can see the gaskets when the window is open. To keep the house warm and clean, they should fit evenly around the sash. Also, make sure the drainage slots (weep holes) are open and clear so that rainwater can drain away.
What homeowners should look for:
- Gaskets are intact and evenly spaced
- No parts of the gasket are loose or twisted
- The drainage slots are clear
Glass Installation and Beads
Once the frame is secure, the glass panels are put in place. Beading holds the glass firmly in the frame. Homeowners can check if the glass is level and the beading is even.
What homeowners should check:
- The glass is stable and doesn’t move
- The beading fits perfectly
- Ensure no gaps around the glass
How Shutters Work and Move
After the window is put together, the shutter is opened and closed a few times. If the movement is smooth, the alignment and fit are correct.
Homeowners should check the movement of the shutters themselves to make sure there is no noise, friction, or stiffness.
What homeowners should look at:
- Easy to open and close
- No scraping or pushing back
- When closed, the shutter lines up correctly
Hardware
During installation, the handles, hinges, and locking systems are all checked. Locks should engage and release easily, without applying force.
Homeowners should try out the locking system themselves to make sure it is simple to use and comfortable.
What homeowners should check:
- Proper working of locks
- Handles work well
- No extra force needed
Final Cleaning
After the uPVC window frames are placed, the protective films are taken off. The area is cleaned up of installation debris, and the glass and frames are cleaned.
A clean finish means that the installation work is finished and ready to use.
What homeowners should look for:
- Protective films are taken off
- Cleaned frames and glass
- The area around the window is clean

Last Check Before Signing Off
A final review is done before the installation is considered complete. Homeowners can check again to see how the windows work, how they lock, and how they look overall.
At this point, the installation team is still there, so you can voice any concerns you may have.
What homeowners should check:
- All windows work fine
- The quality of the finish
- Before signing off, questions are answered
