Railing and coping for balconies and verandas renovationKakeru Koumuten Co., Ltd. is here to help!
What are railings and copings?
This page provides an explanation of railing and coping renovations and their costs!
A railing is the part of a balcony or veranda that serves as a handle, helping to prevent falls and accidents.
A coping is installed at the top of the waist wall of a balcony or veranda, as shown in the photo above.
The main role of the coping is waterproofing, and if the coping itself or the underlying structure deteriorates, it can lead to leaks.
While leaks in balconies and verandas are often thought to be caused by floor waterproofing or exterior walls, it is very common for leaks to originate from the coping, making it a crucial area.
Methods and costs for coping renovation
We will explain the repair and renovation methods for railings and copings by categorizing them!
30年以上
Over 40 years
※Costs can vary significantly depending on the shape, quantity, condition of the substrate, type of new materials, and size of the cap.
If you would like a detailed estimate, please feel free to contact us!
Estimates are completely free of charge.
We will explain the repair and renovation methods for handrails and caps by pattern!
1. Sealing Repair
Sealing Repair
We will repair areas prone to leaks, such as the joints of the caps, with sealing material!
In cases where leaks are caused by joints, this often stops the leaks!
2. Cap Painting
Cap Painting (3 Coats)
This involves painting metal caps, etc. The primary purpose is to enhance aesthetics and prevent deterioration.
If leaks are occurring, painting will not stop the leaks.
Painting aluminum caps is generally not recommended, but it can be done using a strong primer.
However, the paint on aluminum caps does not last long.
3. Metal Replacement (Galvalume Steel)
Galvalume Steel Cap “JFE Steel/Kiwami MAX”
This work involves processing and installing Galvalume steel sheet metal onto the existing cap!
It prevents leaks and is made from highly durable materials, making it a recommended renovation method.
The Galvalume steel used is “JFE Steel/Kiwami MAX”, which has an expected durability of over 30 years and comes with a 15-year coating warranty and a 25-year hole warranty, providing peace of mind with solid manufacturer guarantees!
A disadvantage compared to aluminum caps is that they are more prone to dents and holes caused by impacts.
4. Metal Replacement (Aluminum)
Aluminum Cap “Lixil/Handline III”
Aluminum caps are highly durable and resistant to impacts, making them the most suitable option for verandas and balconies.
They come in a variety of colors, including stylish wood grain designs, making them a popular choice.
A disadvantage is that they may not be suitable for complex-shaped caps.
5. Handrail Installation
Lixil/Bar Handrail
If installed simultaneously with the aluminum cap, you can also choose an integrated type!
It is also possible to add it later to the Galvalume steel cap.
If the substrate is corroded, substrate work will be necessary!
Corroded Substrate of the Cap
If the wooden part of the cap substrate is corroded, as shown in the above photo, it will need to be replaced, and costs will vary depending on the extent of the corrosion.
If leaks or instability of the cap occur, neglecting it will lead to further corrosion, so we recommend prompt cap repairs!
