We present an axiomatic approach to combination theorems for various
homological properties of groups and, more generally, of chain complexes.
Examples of such properties include algebraic finiteness properties,
$\ell^2$-invisibility, $\ell^2$-acyclicity, lower bounds for Novikov--Shubin
invariants, and vanishing of homology growth. We introduce an algebraic version
of Ab\'ert--Bergeron--Fr\k{a}czyk--Gaboriau's cheap rebuilding property that
implies vanishing of torsion homology growth and admits a combination theorem.
As an application, we show that certain graphs of groups with amenable vertex
groups and elementary amenable edge groups have vanishing torsion homology
growth.
