Riser replacement, water, gas, and waste pipe systems in residential buildings. Materials with a lifespan of up to 50 years.
Water riser replacement
Vertical drinking water distribution throughout the building
Horizontal water pipe replacement
Horizontal distribution in basement areas
Waste riser replacement
Drain pipes from upper floors to the public sewer connection
Central gas pipe replacement
Safe gas distribution per current regulations
Hydraulic balancing of heating systems
Even heating throughout the building — no more cold radiators
Thermostatic valve replacement
Modern thermostatic valves for every flat
Boiler room reconstruction
From design to completion, including fault signalling
Is your SVJ planning a riser replacement or boiler room reconstruction? We take care of the entire project. From design through resident communication to handover. Materials that will last another 50 years, and documents for the committee meeting so you can make decisions based on clear information. For smaller repairs in individual flats, see plumbing services.
What Are Central Piping Systems and When to Replace Them
Central piping refers to vertical risers (water, gas, sewage) and horizontal distribution pipes in basement areas. In residential buildings from the 1980s and 1990s, piping was made from steel pipes with a 30–40 year lifespan. Most panel buildings in the Czech Republic are now past that point.
Warning signs: rusty water from the tap, banging pipes, damp patches on walls, frequent minor repairs. Preventive replacement is always cheaper than dealing with an emergency. A burst riser on the fifth floor floods every flat below it.
How Much Does a Riser Replacement Cost in a Residential Building
The price depends on the size of the building, the condition of the pipes, and the material chosen. Approximate figures:
- One riser: approximately CZK 60,000–80,000 excluding VAT (depends on the number of floors, material, and accessibility)
- Typical range for our projects: CZK 300,000–1,600,000
What affects the price: number of flats and floors, condition of existing pipes, chosen material (PPR, copper, stainless steel), scope of work within individual flats.

How the Entire Process Works
A pipe replacement in a residential building affects dozens of households. We have extensive experience with coordination and know how to minimise the impact on residents:
- Site visit and quote. We come, inspect the building, and prepare a quote with a timeline.
- Materials for the SVJ. Budget, schedule, technical description of the work. SVJ members get everything they need for a vote.
- Work in sections. Water supply interruptions are a matter of hours, not days. Residents are informed in advance.
- Resident communication. Notices, coordination of flat access, minimal disruption.
- Handover. Completed project with documentation, inspection reports, and a warranty.
Materials with a 50+ Year Lifespan
New piping should last at least another 50 years. We use:
- Press-fit copper: long lifespan, bacteriostatic properties, proven material
- Press-fit stainless steel: maximum durability, corrosion-free. For larger buildings (from around 60 flats), stainless steel pays for itself.
- REHAU / PPR systems: plastic piping, lower cost, still long-lasting
We recommend the right material based on the type of piping, water quality, and budget.
Hydraulic Balancing of Heating Systems
We offer hydraulic balancing even without replacing the pipes. If your building has cold radiators in one wing and overheated ones in another, balancing the heating system solves it.
At BD Milovice, we balanced the heating in two buildings, approximately 300 radiators. The result: even warmth throughout the building and lower energy consumption.
Materials for the SVJ Meeting
Decision-making in an SVJ takes time. Often months from the initial proposal to the vote. That's why we provide a clear budget, schedule, and easy-to-understand description of the work.
We can also attend the SVJ meeting in person to answer questions. We provide materials you can forward directly to the owners.
Why Choose Kotmel for Central Piping
Materials Built to Last 50 Years
Press-fit copper, press-fit stainless steel, REHAU and PPR systems. New piping should serve for decades — we don't cut corners on materials.
We Handle Resident Communication for You
A reconstruction in a residential building affects dozens of households. We prepare notices, coordinate the schedule, and minimise disruption.
Materials for the Committee Meeting
We provide a budget, schedule, and scope of work. Everything the SVJ committee needs for a vote.
How much does it cost?
The price depends on the number of flats, the condition of existing piping, and the scope of work. Every project is quoted individually after an on-site visit. Typical range for our projects: CZK 300,000 – 1,600,000.
