High-pressure jetting, blockage removal and root cutting - directly from the local provider in Schlieren. 15 min on-site in the city of Zurich, quote before dispatch, no middleman.
Backflow in the basement? Gurgling in the drain? Odour from the shaft? Describe the problem on the phone and we give you the cost before we drive out. No middleman, no surprise price.
The city of Zurich and the surrounding municipalities in the Glatt valley, the Limmat valley and both shores of Lake Zurich form, with roughly 1.6 million inhabitants, one of the densest service areas in Switzerland. Greentech Solutions has operated out of Schlieren since 2017 - 15 minutes to the inner city, under 25 minutes to the districts on the Zuerichberg, on the Gold Coast or in the Zurich Oberland.
Our clients are homeowners with blocked drains as well as property managers with apartment buildings in Wiedikon, Hoengg or Oerlikon, and municipalities with combined sewer lines that are decades old. What they all have in common: they want a reliable local provider who issues a quote before dispatch and does not run a middleman model with hidden mark-ups.
We serve the whole canton of Zurich with all 159 municipalities. The 12 cities below are the ones we visit most - all reachable in 25 minutes or less from our base in Schlieren.
Travel times from our Schlieren base.
Problems differ noticeably between neighbourhoods and regions. What we typically encounter:
Lines from 1880 to 1960, often with stoneware pipes. Typical findings: offsets, cracks and root ingress from old linden and chestnut alleys. Here a TV camera survey to SN EN 13508-2 before any major cleaning is useful, because pure high-pressure jetting can worsen the damage pattern when cracks are present.
Lime deposits from the hard lake water, root ingress from dense shore vegetation, and backflow during heavy rain in the steep slopes above the Seestrasse. Here we use specialised de-scaling nozzles and inspect the backflow protection as a standard part of every intervention.
Combined sewer bottlenecks during heavy rain, high groundwater tables infiltrating defective pipes, and grease residues from commercial and logistics operations around the airport. Here we combine high-pressure jetting with vacuum equipment for a complete cleaning.
Chemical and oil residues from former industrial sites, dense buildings with limited access, and old combined-sewer mains. Compact high-pressure equipment and experience with commercial wastewater are decisive. We document all interventions in line with the Swiss Water Protection Ordinance (GSchV) for the authorities.
The cost of sewer cleaning in Zurich depends on three factors: pipe length, degree of soiling and accessibility. Standard jetting in a single-family home is a different price range than a main line in a 40-unit apartment building or a toilet system in a commercial property.
We work the other way round: you describe the problem on the phone, we give you a written cost estimate before dispatch. No middleman mark-up, no surprise price on arrival. For larger sites or maintenance contracts we prepare a detailed quote on-site on request, at no cost and without obligation.
We ask on the phone: which fixture, since when, which symptoms. From that we pick the right technique - high-pressure jetting, vacuum cleaning or root removal with a specialised nozzle. Every blockage has its right solution.
Hair, grease, lime and foreign objects are the most common causes in the Zurich area. We clear them with 200-bar high-pressure jetting and a camera check. From Schlieren, 15 minutes to the city of Zurich, 24/7 including weekends and holidays. Quote before dispatch, no middleman.
Paper build-up, lime in the trap or foreign objects are typical causes. We clear most toilet blockages in 15 to 30 minutes with high-pressure and vacuum technology, which is gentle on ceramic and gaskets. After cleaning, an inspection check. SN EN 1610 certified.
For basin blockages the obstruction usually sits in the trap (hair, soap residue, jewellery) or in the stack. We clean mechanically or with high-pressure jetting, without dismantling the basin. Function and odour checks afterwards. Owner-run business from Schlieren.
In bath and shower drains the blockage often sits in the stack, where a plunger cannot reach it. Hair and soap-lime accumulate over years. High pressure at 200 bar reaches remote points without dismantling furniture or panelling. Quiet and documented.
Kitchen drains scale up with grease, food residues and detergent residues. Household remedies only address the surface, not the solid lime-grease layer that builds up over years. High-pressure jetting combined with a solvent process removes it completely. For commercial kitchens we also service the grease separator on a 1 to 3 month cycle, which is legally required. A drain check verifies the rest of the pipe run for defects.

PREVENTION BEATS EMERGENCY
No acute issue yet? We inspect your pipes with a CCTV camera — video and report included, no follow-up order required.
The cost depends on three factors: pipe length, degree of soiling and accessibility. Standard jetting in a single-family home is a different price range than a main line in a 40-unit apartment building. You receive a written cost estimate before we drive out, and there is no middleman mark-up.
From our base in Schlieren we reach all 12 Zurich city districts in 15 to 25 minutes, even during peak hours. For emergencies we are available 24/7, including weekends and public holidays.
Yes. Greentech Solutions is reachable 24 hours a day for the city of Zurich and the whole canton. In case of a pipe burst, blockage or backflow, call +41 44 500 92 05 - also at night, on weekends and on public holidays.
Yes. We support property managers, housing cooperatives and homeowner associations across the canton of Zurich. Maintenance contracts with consolidated billing per property, one point of contact, documented interventions on an annual plan.
Many lines in the old town, Aussersihl, Wipkingen and Wiedikon date from between 1880 and 1960. These old stoneware sewers often show offsets, cracks and root ingress. A TV camera survey with condition report is advisable before any major cleaning.
For single-family houses we recommend jetting every 5 to 10 years, for apartment buildings and commercial properties every 2 to 5 years. In Lake Zurich locations with hard water and dense shore vegetation, shorter intervals can make sense.
Yes, especially in neighbourhoods with mature trees - linden and chestnut alleys in the old town, shore vegetation on the Gold Coast, and parks in Hottingen and Witikon. We remove roots with specialised root-cutter nozzles, without excavation.
On steep slopes above the Seestrasse, heavy rain regularly causes backflow because the combined sewer system reaches its capacity limit. We recommend inspecting the backflow protection before every storm season - a camera survey reveals potential weak points.
Yes. TV camera surveys to SN EN 13508-2 are a standard part of our offering. You receive a digital condition report with damage classification, which is the basis for a well-founded rehabilitation decision.
Yes. We serve the whole canton of Zurich - from Schlieren to Winterthur, from the Gold Coast to the wine country. We reach Winterthur in 25 minutes, Uster and Wetzikon in 20 to 25 minutes.
Do not keep flushing, it makes the backup worse. Call +41 44 500 92 05. Together on the phone we decide: high-pressure jetting, root removal or emergency dispatch with camera. From Schlieren we reach all 12 Zurich city districts in 15 to 25 minutes, 24/7. Quote before dispatch, no middleman mark-up.
Stop flushing - a blocked toilet risks overflow. Household tools like a plunger only help with surface blockages. For deeper obstructions (paper build-up, lime in the trap, foreign objects), high-pressure or vacuum technology is needed. We resolve most cases in 15 to 30 minutes without dismantling anything.
That depends on your plumbing knowledge. Opening the trap is doable - be careful with gaskets and union nuts. If blockages recur, the actual issue usually sits further down the stack, where only high-pressure jetting or a drain snake helps. We clean without dismantling and check flow and odour afterwards.
In bath and shower drains, the blockage often sits in the stack, not in the trap - a plunger cannot reach it. Hair and soap-lime accumulate into solid plugs over the years. High-pressure jetting at 200 bar clears them without dismantling furniture or panelling. On request we run a TV inspection to confirm the cause.
Household remedies handle odour and light films, but not the hard grease-lime layer that builds up over years. That requires high-pressure jetting combined with a solvent process. For commercial kitchens we also service the grease separator on a 1 to 3 month cycle, which is legally required.
