Why Builders Will be Moving to uPVC Rainwater Gutters in 2026
For a homeowner, the monsoon is a season of mixed emotions. While the cooling rain is a relief from the heat, it also brings a silent threat to the most expensive parts of your house: the exterior finishes. We spend lakhs of rupees on premium weather-shield paints, designer wall tiles, and elegant landscaping, only to watch them deteriorate year after year.
The culprit? Rainwater overflows.
When your roof lacks a high-performance gutter system, or if you have installed an inferior, low-capacity pipe, the water doesn’t just flow away. It overflows, splashes, and seeps. At Besguard, we’ve seen how this “uncontrolled water” can age a new house by ten years in a single season.
In this article, we’ll explore the specific ways rainwater overflow destroys your home’s beauty and why a professional uPVC gutter system is the only permanent solution.
The exterior paint of your home is its first line of defense. However, even the most expensive “weatherproof” paint has a limit. When rainwater overflows from the roof, it doesn’t just hit the wall; it saturates it.
Constant water flow creates a “soaking effect.” Moisture gets trapped between the paint layer and the cement plaster. As the sun comes out and the wall heats up, this trapped moisture turns into vapor, creating pressure that causes the paint to bubble and eventually flake off.
Have you noticed dark, vertical streaks on the walls of buildings? These are caused by dust and pollutants on the roof being washed down in concentrated streams during an overflow. These stains are often permanent and require a complete repaint to fix.
Many modern homes in Kerala and across India use stone cladding or ceramic wall tiles for aesthetics. These are held together by adhesives or cement mortar.
Rainwater overflow is the enemy of these installations. When water constantly pours behind the tiles through tiny gaps or grout lines, it weakens the bond. Over time:
You might notice a “hollow” sound when tapping them.
In extreme cases, the weight of the water-logged tiles causes them to fall off entirely, posing a safety risk and leaving an ugly patch on your elevation.
Overflowing water brings out white, salty deposits from the cement (efflorescence), which crystallize on the surface of your beautiful tiles, making them look dull and aged.
Damage doesn’t only happen from the top. When water falls from a height of 10 or 20 feet because there are no gutters, it hits the ground with incredible velocity. This creates a “splash-back.”
This mud-filled water hits the bottom 2-3 feet of your home. This is why you often see the base of beautiful houses covered in brownish-red mud stains and green algae. This constant dampness at the base leads to “rising damp,” where moisture travels upward through the wall, ruining your interior wallpaper and wooden cupboards on the other side.
In tropical climates, moisture equals life for all the wrong things. Overflowing water keeps your walls damp for extended periods. This creates a perfect breeding ground for:
These organisms eat away at the organic components of your paint.
The green slime that makes your home look neglected and slippery. Beyond aesthetics, mold spores can enter your home through windows and vents, triggering allergies and respiratory issues for your family.
At Besguard, we analyzed why traditional gutters fail and lead to overflow. Most “local” gutters are too small, they sag, or they clog. We engineered our uPVC Rainwater Systems to be different.
Our gutters aren’t just round pipes cut in half. The Besguard “Square-Line” or Trapezoidal design is scientifically engineered to carry a much higher volume of water. This ensures that even during a heavy Kerala “mini-cloudburst,” the water stays inside the canal and moves toward the downtake pipe, rather than spilling over the sides.
One of the biggest causes of overflow in cheap gutters is “sagging.” When a gutter bends under the weight of water or heat, it creates a low point where water pools and eventually overflows. Besguard’s Internally Reinforced (IR) Ribs provide the longitudinal strength needed to keep the gutter perfectly level for decades.
Metal gutters rust, and cheap plastic becomes brittle. Besguard uses high-grade uPVC that withstands the harsh Indian sun. It doesn’t crack or warp, meaning the “overflow protection” you buy today will still be working 10 or 15 years later.
An overflow often happens at the joints if they aren’t seamless. Our precision-engineered fittings and rubber gaskets ensure a watertight seal, so the water goes exactly where it’s supposed to away from your walls.
Repainting a medium-sized house can cost anywhere from ₹50,000 to ₹2,00,000. Replacing damaged wall tiles or fixing structural dampness can cost even more.
Installing a Besguard Rainwater Gutter system is a fraction of that cost. It is an investment that pays for itself by doubling the life of your exterior paint and preserving the “showroom look” of your home.
