Installation time for underfloor heating depends on the system type and the scale of the project. A single-room electric mat or cable installation can typically be completed within one working day. Larger electric installations across multiple rooms may take two to three days. Hydronic systems require coordination with screeding, plumbing, and flooring contractors, a full installation across a larger home can take several days to a week.

For new builds, the ideal time to install underfloor heating is during the screed or subfloor stage, before tiling or floor coverings are laid. Retrofitting is possible but more disruptive and costly. Cape Decking works closely with homeowners, contractors, and architects across Cape Town to align installation with your project schedule.
