Marco Construction Ltd — Red Seal GC for Renovations, Additions & Basements in Grimsby, ON
Marco Construction Ltd. is a general contractor run by a Red Seal licensed General Carpenter, operating out of 6 Aspen Drive in Grimsby’s residential grid south of the QEW. The shop’s positioning is trade-led — Red Seal carpentry first, with licensed subcontractors folded in for mechanical/electrical scopes — which tends to show up in the framing, trim and built-in details where homeowners first notice the difference between a carpenter-run GC and a pure project-management shop.
Services
- Full-scope kitchen renovations (demo, layout, cabinetry install, finish carpentry)
- Bathroom renovations, including full-gut rebuilds and accessibility modifications
- Basement finishing — framing, insulation, mechanical rough-in coordination, finish work
- Additions and second-storey builds tied into existing envelope and roof lines
- Residential and light-commercial reno-scope work
Service Area
Grimsby, Beamsville, Lincoln, Niagara-on-the-Lake, St. Catharines, Burlington and Oakville — essentially the QEW corridor from Niagara Region through to Halton.
Why it’s on home.renovation.reviews
We listed Marco Construction because the directory already has carpenter-led options in Grimsby (Davies Home Improvements) and because homeowners doing a basement or bathroom in a 1970s-80s Grimsby subdivision tend to flag the same questions about trim-return quality and cabinet alignment — a Red Seal-led shop is worth naming separately. HomeStars and Houzz profiles both carry positive trade-quality notes.
