The frequency of re-waterproofing uPVC doors and windows depends on several factors, including the quality of the original installation, the products used, and the environmental conditions they are exposed to. Generally, uPVC doors and windows should be inspected and potentially re-waterproofed every 5 to 10 years. However, more frequent maintenance may be necessary under certain circumstances.
Factors Influencing Re-Waterproofing Frequency
1. Quality of Original Installation: A well-installed uPVC door or window with high-quality sealants and gaskets will generally require less frequent re-waterproofing.
2. Exposure to Elements: Windows and doors exposed to harsh weather conditions (e.g., heavy rain, high winds, or extreme temperatures) may require more frequent inspections and maintenance.
3. Type of Sealants and Gaskets: The durability of the materials used for sealing, such as silicone sealants and EPDM gaskets, can affect how long the waterproofing remains effective.
4. Environmental Factors: Homes in coastal areas, for example, may experience more rapid deterioration of seals due to salt air and humidity, necessitating more frequent re-waterproofing.
5. Wear and Tear: Frequent use and opening/closing of windows and doors can wear down seals and gaskets, potentially leading to leaks.
Recommended Maintenance Schedule
1. Annual Inspection: At least once a year, inspect all uPVC doors and windows for signs of wear, damage, or leaks. Pay special attention to the seals, gaskets, and weatherstripping.
2. Re-Waterproofing Every 5-10 Years: Generally, it’s advisable to reapply sealants and replace gaskets every 5 to 10 years, depending on the condition of the existing materials and the factors mentioned above.
3. After Severe Weather Events: If your area experiences a severe weather event, such as a storm or heavy rainfall, inspect your uPVC doors and windows for any damage or leaks and address any issues promptly.
4. Spot Maintenance as Needed: If you notice any gaps, cracks, or signs of water ingress, reapply sealant or replace gaskets immediately to prevent further damage.
Conclusion
Regular inspection and timely maintenance of uPVC doors and windows are crucial to ensure they remain watertight and function effectively. While re-waterproofing is typically needed every 5 to 10 years, it’s important to monitor their condition and address any issues as they arise. By doing so, you can extend the lifespan of your uPVC installations and maintain a comfortable, dry indoor environment.
