Wirmax Wise
An energy renovation with a single contract
Wirmax Wise is a complete solution for housing companies and commercial properties that cuts the amount of purchased energy by up to 60–70%. The parts of the energy renovation are designed, delivered and maintained by a single supplier, so the board does not need to assemble the whole from several separate procurements.
You receive one fixed-price quote, and project management comes from one company. We deliver Wise solutions in the Uusimaa region.
For you, who make decisions about the property
For the housing company board
The board needs a reliable basis for decision-making. We survey the property's technical systems, and you receive a clear quote showing the investment, schedule and options before any decision is made.
For the property manager
You get one contact person who handles the matter from start to finish. You always know how the work is progressing: completed work is documented digitally, resident communications are agreed together and our emergency service responds to faults 24/7.
For the real estate manager
Several properties in the care of one partner with an annual technical maintenance contract. Remote monitoring and preventive maintenance keep conditions and energy consumption under control, and every property's maintenance history is documented.
Why choose Wirmax
Building services, done better – that is our promise. This is how we work on every housing company project, from a small maintenance call to a large contract.
All building services under one roof
HVAC, electrical, heat pumps, automation and security technology from one partner. Around 100 building services professionals take care of the property's HVAC, electrical, automation and telecom (LVISAT) technology, so the board does not need to assemble the whole from several separate procurements.
What we agree, we deliver
When we agree on the price, schedule or scope of work, we stick to it. If something changes, we tell you before you need to ask.
You know where things stand
Completed work is always documented digitally, and we report on the progress of maintenance work through our own app. The property manager does not need to chase us.
Responsibility stays with us
When needed, we bring the right experts together on the same issue, but the housing company does not need to act as project manager. We also deliver large contracts with full responsibility.
Experience in renovation construction
We have more than 20 years of experience in housing company pipe renovations and renovation projects, and our customer satisfaction is 4.5/5.
A step ahead of problems
Remote monitoring and preventive maintenance keep the technology in good order, and in the event of a fault our emergency service responds 24/7. We fix the cause, not just the symptom.
