The Ranking
Our top 5 general contractors in Hamilton
Hamilton is a city of old houses and big plans. Century homes in the lower city and Dundas, postwar bungalows on the Mountain and newer builds in Stoney Creek and Ancaster all hit the same wall sooner or later: the work no longer fits one trade. A rear addition, a legal second suite, a load-bearing wall coming out or a full gut down to the studs means design drawings, permits, inspections and half a dozen trades that have to show up in the right order. That is the job of a general contractor, and it is a different job from swapping out a kitchen.
Ontario does not issue a general provincial licence to residential general contractors. Building permits come from the City of Hamilton's building division, and structural work, additions and many basement projects need one. HCRA licenses builders of new homes, and Tarion warranty covers new homes rather than most renovations, so on a renovation the checking is yours. Before you sign, ask for a written and itemized contract, a current liability insurance certificate, a WSIB clearance certificate, the name of whoever applies for the permit and books the inspections, and a warranty on labour in writing. The City of Hamilton can tell you what your project needs before you commit.
The five companies below work out of real offices in Hamilton, including Stoney Creek and Ancaster. We looked at Google rating and review count, whether the company has a working website and a staffed address, which general contracting services it actually describes (whole-home work, additions, design-build, permits, custom homes), and what its photos show. Most of them also appear on our home remodeling list, since the best Hamilton renovators often run full projects, and each profile says where a company publishes little about licences or insurance so you know what to ask for.
