uPVC windows are a preferred choice in Saudi Arabia for heat and sound insulation, but they occasionally face some issues, such as leaks, difficulty in opening and closing, and external noise.
At Home View Saudi Arabia, we are keen to provide our customers with practical solutions to these problems in a simplified manner. This article reviews the most common uPVC window problems, and the available solutions to maintain comfort and ideal insulation in your home.
First – The Problem of Leaking Windows: Causes and Remedies
Often, water or air leakage occurs due to a defect in the insulation around the window frame or blocked drainage channels (weep holes).
During window installation, gaps in insulation may appear, or damage to the rubber gaskets can occur; therefore, it is recommended to check the seals around the window regularly and replace damaged gaskets.
Additionally, blocked drainage holes lead to rainwater pooling inside the frame, and subsequently leaking inside.
Solutions for Window Leakage Problems
1 – Cleaning Drainage Channels (Weep Holes)
Use a soft brush or water from a hose with slightly strong pressure to remove dirt from the drainage holes, so that water flows outwards without accumulating inside the frame.
2 – Resealing the Frame
If the insulation was applied using silicone or insulating foam, new sealant silicone must be applied around the window edges after cleaning the old one. Use a high-quality special silicone like Dow Corning to fill any cracks.
3 – Checking the Filter Slope (Virtual Window Ceiling)
Ensure the window is slightly tilted outwards so that water does not pool. Incorrect installation with a downward tilt can cause water to stay at the edges.
4 – Ensuring the Frame is Secured
If the frame is loose, it must be firmly fixed with screws, and gaps around it should be filled with polyurethane foam (expanding foam) and then re-covered with silicone.
Bottom Line
Leakage is often due to seal failure or blocked drainage. Solutions begin with inspecting and cleaning the frame gaskets and resealing any gaps.

Tip
In the hot and dry Saudi climate, dust significantly affects window closure. Therefore, we advise conducting an inspection and cleaning of drainage holes at least every 6 months.
Second – The Problem of Difficulty Opening or Closing Windows | With Solution Steps
If windows become heavy to open or close with difficulty, this may be due to many reasons related to mechanical mechanisms. These include accumulation of dust and oils in the window tracks, or misalignment of hinges and their parts.
Additionally, problems can occur when moving the window in the case of a misaligned frame or loose hinge screws.
Solutions for Opening and Closing Window Problems
1 – Cleaning Tracks and Rollers
First, inspect the movement track if the window is sliding, and remove any dust or debris. Use a small hand vacuum or a soft cloth to wipe the tracks.
2 – Lubricating Hinges and Locks
After cleaning, apply a few drops of multi-purpose lubricant such as PMA Multi-Lube or WD-40 on hinges and rollers; this simplifies window movement and reduces squeaking.
According to Home View experts, it is recommended to use light lubricant or silicone spray for hinges and locks.
Important Warning:
Avoid heavy oil such as engine oils, as they attract dust and clump together.
3 – Adjusting Window Hinges
Most uPVC windows have adjustment screws (Allen keys) in the hinges. Using a suitable Allen wrench, you can adjust the hinge height and depth so that the windows sit perfectly inside the frame. This correction restores smooth access.
4 – Inspecting the Multi-Point Locking System
If windows are equipped with a multi-point locking system, ensure there is no defect in it. You may need to lubricate the locking mechanism or replace a part that appears incomplete if affected by rust or damage.
5 – Replacing Damaged Parts
If pull rollers are damaged (in sliding windows) or non-repairable hinges fail, it is best to change them with compatible original parts to maintain smooth opening.
With these simple procedures, the problem of difficulty in opening windows can be treated.
In Brief
Cleaning the tracks, lubricating moving parts, and adjusting hinges is usually sufficient to solve the problem without needing a full window replacement.

Third – Eliminating Noise (Sound Insulation Issues)
Some of our customers suffer from external noise passing through old or poorly insulated windows. The cause is often thin glass or insufficient sealing that allows sound to leak.
Solutions for Sound Insulation Problems in Windows
To get rid of annoying sounds, we recommend the following:
1 – Sealing Gaps Around the Frame
Any small gap between the frame and the wall can transmit sound. Use acoustic silicone or rubber weatherstripping (EPDM) around the window to ensure a tight seal.
2 – Replacing Glass with Insulating Panes
If old glass leads to echoes and noise, you can easily replace it with a double glazing unit of two layers, or even 3 layers, or tempered (soundproof) glass.
This increases window thickness and effectively reduces noise.
3 – Improving the Seal
Check the insulation gaskets and ensure they are intact without tears. Worn gaskets cause air flow and noise. If necessary, reinstall new high-quality gaskets like EPDM.
4 – Additional Tips
Thick curtains or internal sound absorption barriers can also be added. Generally, the thicker the window (profile thickness and double glazing), the better the sound insulation.
In Brief
It is important to know that sound insulation is effective in good-quality uPVC windows equipped with double glazing.
Any gap in the seal means hearing noise. Consequently, solutions focus on filling gaps and installing sound insulators.

Timeline for Inspection, Periodic Maintenance, and Prevention of uPVC Window Problems
Regularly caring for windows is the best investment to prevent most of the previous problems. uPVC maintenance does not require complex tools; a bucket of water and mild soap, a soft cloth, and lubricating oil are enough.
Below is a summary table of basic maintenance steps and their frequency:
| Step | Description | Frequency |
| 1. Cleaning with water and soap | Wipe the frame and glass with a mild soap solution to remove dust and debris | Once every 3 – 6 months |
| 2. Lubricating hinges and locks | Apply a few drops of lubricating oil (such as PMA Multi-Lube or WD-40) when hearing any squeak | As needed when squeaking occurs, and can also be applied during every cleaning |
| 3. Inspecting and adjusting the frame | Check the tilt in the window and adjust hinge screws if necessary | Annually or when a defect is noticed |
| 4. Replacing damaged parts | Replace any handle or cracked rubber gasket immediately to avoid loss of insulation | As per condition |
| 5. Inspecting holes and channels | Clean drainage holes and tracks of dirt; apply water repellent if leakage occurs. | When water leaks, ideally every 6 months |
By adhering to these simple steps, your windows will work efficiently throughout the year, and you will avoid costly repairs later.
Common uPVC Window Problem Solutions: Repair or Replacement?
When your windows face deep failures, many may wonder: Is it worth repairing or does it require replacement?
As experts explain, repair is often sufficient in early stages. For example, a broken handle can be easily changed, and minor cracks in the frame can be bonded with special adhesives, while large dents or frame warping may necessitate replacement.
However, if the double glazing is damaged and heat insulation is lost, there are techniques that allow replacing only the glass unit without changing the entire frame.
In short, uPVC windows are repairable to a large extent, and should only be fully replaced in rare extreme cases.
These easy solutions to usual problems have enabled window maintenance to be done by yourself in many cases, but professional specialized maintenance remains a good option, especially if windows are old or the problem is complex.
Engineers and technicians of Home View Saudi Arabia are always ready to provide consultation and implement necessary maintenance or repair services to ensure the best results for our customers.
FAQs about uPVC Window Problems
How to repair damaged uPVC?
Self-repair is possible for small surface cracks only. Start by cleaning the crack with an alcohol cleaner, then use a two-part uPVC repair compound to fill the crack.
After the compound dries, sand the excess until the surface is level. This method is temporary and does not return the window to brand new, but it prevents the damage from worsening. If cracks are large or the window frame is deformed, it is best to call a specialized technician or replace the entire unit.
What are the disadvantages of uPVC windows?
Despite their advantages, there are some important points regarding uPVC windows:
First, sensitivity to thermal expansion and contraction; high temperatures may cause short-term expansion in the material and loss of seal tightness.
Second, the range of design and colors is limited compared to wood or aluminum. They may also cost slightly more initially.
Why won’t my uPVC windows close properly?
The problem is usually due to a misaligned frame or damage to hinges and locks. First, check that the window is completely closed and handles work, as some multi-point systems need to be closed gradually.
Then inspect the hinges; their screws may be loose or need an angle adjustment. Lubricate hinges and locks with light oil, then adjust with an Allen key until the frame sits in place.
In difficult cases, it may require replacing part of the locking system or a frame support.
What is the best lubricant for uPVC windows?
We recommend special light oils, such as silicone spray or precision oils for lubricating hinges and locks. Avoid heavy oils (like engine oil) because they attract dust and hinder movement over time. Generally, clear silicone oil is safe and leaves no sticky traces.
How to improve old uPVC windows?
Insulation and maintenance can be enhanced in several stages; replace old rubber gaskets and insulating strips (EPDM) with new ones to prevent any leakage.
If units include double glazing but are in poor condition, or part of it is missing and the remainder is single glass, consider replacing them with modern heat and sound insulating double units.
Refill the frame perimeter with silicone to ensure a tight seal, and use polyurethane foam to fill gaps between the wall and frame. You can also hone hinges and locks periodically to maintain efficiency.
How to fix uPVC window scratches?
Minor surface scratches can be treated gently; clean the area, then use uPVC smoothing paste and colors can be chosen with special touches (colored samples available) to fill the scratches.
Wipe away the excess, then leave it to dry. For deep scratches, the procedure may take longer, and marks may remain slightly visible. Unfortunately, there is no permanent solution for major scratches other than replacing the damaged part of the frame.
Can you repair old uPVC windows?
Many window failures can be repaired such as replacing rubber gaskets, glass, or hinges, but they require skill and knowledge of the window system.
If mechanical parts are good, maintenance and improvement are sufficient for years. However, if frames are cracked or significantly warped (due to excessive heat or impacts, for example), full replacement may be better than continuing repeated repairs.
How to fix a loose uPVC window frame?
A loose frame means the frame is no longer firmly fixed in the wall opening. For remedy, unscrew the framing screws in the frame, then press the frame well and reinstall it in its correct position.
Retighten the screws firmly with a suitable screwdriver. If a gap remains between the wall and frame, you can fill it with polyurethane foam (expanding foam) and then trim the excess.
Finally, seal final gaps with external silicone for a tight seal.
How to adjust old uPVC windows?
- Adjustment includes setting hinges and locks and maintaining parts.
- Use an Allen key to adjust hinges so the window sash becomes perfectly balanced inside the frame.
- In many systems, the window closure angle can also be adjusted by inserting a small screwdriver into the adjustment hole in the track.
- Ensure the handle aligns in the middle of the frame during closure.
- Furthermore, lubricate hinges and locks regularly, and replace any worn or cracked parts to ensure the window works smoothly.
How are uPVC windows repaired?
uPVC windows are repaired according to the type of problem. For example:
- Loose closure problem is solved by adjusting hinges or the multi-point locking system.
- Difficulty opening or friction is treated by cleaning the track and lubricating rollers and hinges with light silicone oil.
- Air or water leakage is treated by replacing the rubber gasket or reapplying insulating silicone around the frame.
- Glass problems such as cracking or condensation between panes usually necessitate replacing only the double glazing unit without changing the frame.
Can you repair peeling uPVC window frames?
uPVC usually does not peel because it is not painted, but faded spots or chalky lines may appear due to the sun or unsuitable cleaning materials. This can be repaired by:
- Cleaning the surface with a solution dedicated to uPVC.
- Using uPVC Restorer (specialized polishing cleaners) to restore color and shine.
- In severe cases, the surface can be covered with a special thermal Foil Wrap for windows, which is a practical and inexpensive solution compared to changing the full frame.
In General, uPVC Window Problems are neither many nor major!
The solutions above show that it is possible to repair most uPVC window failures easily without replacing the entire window, provided regular maintenance is performed.
