PROFESSIONAL VERANDA WATERFLOW PROTECTION
Professional treatment of a blockage in a patio gutter (gutter) concerns three basic points: causes, treatment, and prevention.
Causes of a clogged gutter
Patio gutters usually become clogged due to the accumulation of leaves, branches, mud or other foreign bodies (such as soil, plastics) in the siphons or sinks. Over time, these materials condense and create a barrier, preventing the flow of water. More rarely, the blockage can be due to burst pipes or incorrect system design. Below is a detailed presentation of the causes of clogged patio gutters, based on our experiences from real cases:
Natural materials and organic residues
- Leaves and plant debris: A major cause, especially on patios with pots or trees. Leaves, pine needles, flowers or branches accumulate in the spout or pipes, creating a blockage.
- Soil and mud: From pots or atmospheric pollution, they form silty deposits that reduce the flow cross-section and lead to complete blockage over time.
- Plant roots: In older installations, roots can penetrate pipe cracks, blocking flow.
Human use
- Daily activities . Cleaning the terrace with a broom or water pushes garbage (trash, cigarettes, plastics) towards the gutters. Watering plants carries soil and biological residues into the siphons.
- Incorrect disposal of materials . Throwing waste (e.g. paper, plastic packaging) directly into the gutters.
- Using chemical or “homemade” solutions . Attempting natural methods such as Coca-Cola, vinegar or salt may accelerate the accumulation of sediment.
Structural issues and defects
- Incorrect pipe slope . If the drain pipe does not have sufficient slope (>2%), water does not drain, allowing solids to accumulate.
- Insufficient pipe diameter or incomplete grate . Narrow pipes or protective grates with large holes allow debris to enter easily.
- Age or frost damage . Cracks in old pipes (mostly metal) allow dirt to get in. Frost can cause them to burst, increasing the risk of blockages.
Environmental impacts
- Severe weather events . Storms carry large amounts of leaves/trash at once, overwhelming drainage capacity.
- Animal presence . Bird nests, dead insects or rodents obstruct flow, especially in unused gutters.
- Dust and sandstorms . In urban areas with high air pollution, dust creates viscous deposits.
Other factors
- Insufficient maintenance . Lack of regular cleaning (especially before the rainy season) allows blockages to gradually accumulate.
- Relationship with the architecture of the building . Vertical gutters on ground floors are more vulnerable to soil accumulation, while horizontal gutters on upper floors tend to become blocked by leaves.
For effective treatment, regular inspection of outlets and pipes (especially before rain) and installation of fine-textured filters are recommended . In cases of frequent episodes, evaluate the revision of the system (slope, materials).
Professional treatment for blocked gutter
Our professional technicians primarily treat blockages with specialized high-pressure mechanical cleaning, which breaks up the blockage and removes deposits from the pipes. In cases of serious blockages or access to hidden areas, a drain endoscopy camera may be used for accurate diagnosis, followed by mechanical cleaning with specialized tools. These techniques require expertise and equipment for effectiveness and safety without damaging the system.


Accurate Diagnosis with Sewer Camera
A special camera is inserted into the pipes to identify the exact location and nature of blockages (roots, sediments, cracks). We also check the slope, diameter and general condition of the pipes. With this process we achieve documentation of damage before/after the intervention (evidence material).
Gutter Cleaning & Unclogging Methods
- Hydraulic pressure (Hydrojet) :
∙ High pressure pumps with specialized heads.
∙ Adjustable nozzles for different pipes (PVC, metal).
∙ Decomposition of sediments/roots without pipe damage. - Electromechanical steel :
∙ For dense obstacles (e.g. stones, metal objects).
∙ Spiral hooks “grab” and extract the obstacle.
Preventive practices to avoid clogged gutters

To prevent future blockages, it is recommended to regularly clean the balcony siphons and the drain hole from leaves and debris, especially before the rainy season. The installation of protective siphons with a fine mesh or special filters intercepts solid materials before they enter the system. Also, periodic inspection and light cleaning with pressure water can maintain the efficiency of the drainage. In cases of frequent problems, it is worth considering optimizing the slope of the pipes or changing materials (PVC) to improve flow. For effective solutions to complex drainage issues, advice from our specialist technician ensures correct diagnosis and intervention.
CONSEQUENCES OF A CLOGGED VERANDA DRAIN

- Overflow & Standing Water
The most immediate problem is the accumulation of water on the terrace due to zero drainage. Standing water creates a slip hazard, causes permanent moisture and damages the floors (wood, tiles, concrete), leading to delamination or cracks. - Structural Damage
Continuous exposure to moisture corrodes materials (magpie, reinforced concrete, metals). On terraces with solar exposure, stagnant water accelerates floor wear due to thermal expansion/contraction. - Biological Hazards
Standing water becomes a breeding ground for mosquitoes and other insects. In addition, moisture feeds mold and fungi on walls/ceilings, affecting air quality and health (allergies, respiratory problems). - Building & Property Damage
Moisture can corrode supports, cause damage to cabinets or patio furniture, and even penetrate the interior of the building (damage to upholstery, insulation, electrical installations). - Financial & Aesthetic Cost
Repairing structural damage or replacing floors is expensive. At the same time, water stains, mold and accumulated trash reduce the aesthetic value of the property.
CAUTION : The longer the blockage is delayed, the more wear and tear and damage will occur. Professional intervention is necessary to prevent the problem from escalating.
