Astaneh Construction vs Ace Build Contracting: which fits your home addition or second storey?
Both of these contractors show up as strong options for a home addition or second storey project, and both carry near-perfect reputations, so the choice comes down to fit rather than a big quality gap. This comparison looks at how each handles the specific demands of an addition or storey add, like permits, structural coordination, and staying in touch over a multi-month build, based on our methodology.
The differences that matter
- Permits and inspections in-house. Ace Build Contracting explicitly handles permits and inspections as part of its service, which matters directly for additions and second storeys that require structural sign-off; Astaneh's data doesn't call this out as a stated service.
- Project management style. Astaneh leans on a named project manager (Rana) for daily communication and site coordination, while Ace runs on a system of weekly photo updates and same-day responses, useful for owners who can't visit the site often during a long build.
- Track record on larger, multi-trade jobs. Ace's review history specifically references full-home extensions and legal basements across Mississauga, Etobicoke, Burlington, and Toronto, giving more direct evidence of second-storey-scale work than Astaneh's, which centers more on kitchens, basements, and whole-home gut renovations.
- Licensing and liability documentation. Ace is described as HCRA-licensed with $5M liability coverage stated outright, a detail that matters for a project involving structural changes and new floor loads; this specific figure isn't part of Astaneh's listed facts.
- Review volume and consistency. Ace has more reviews overall (147 vs 118) and a slightly higher volume sub-score, though Astaneh edges it on rating and recency sub-scores, so both show active, current client bases.

What reviewers say
Astaneh Construction
Reviewers consistently report stress-free renovations completed on time and on budget. Hamed and his team, particularly project manager Rana, combine clear daily communication with honest pricing and meticulous work.
Home and kitchen renovations, basement finishes, and whole-home gut jobs all drew five-star praise. Subcontractors are vetted and respected. One photographer noted Hamed's rare combination of organization, high materials standards, and reliability across the construction field.
Ace Build Contracting
Reviewers consistently report smooth projects with strong communication: weekly photo updates, same-day responses, and clear pricing for any changes. Leadership by Abbi and the broader team earned trust even from busy homeowners managing major additions and renovations. Work spans kitchens, bathrooms, legal basements, and full-home extensions in Mississauga, Etobicoke, Burlington, and Toronto, with craftsmanship praised for framing, drywall, cabinetry, tile, and finishes.
Projects stay on timeline and budget, sites remain clean, and permits and inspections are handled as part of the service. Even a kitchen cabinet manufacturer trusted them as partners. The only concrete detail missing from reviews is response to budget overruns or delays-none were mentioned across 18 reviews, suggesting either rare occurrence or happy resolution.
Which should you pick?
Pick Astaneh Construction if
- You want a tight, named point of contact (project manager) coordinating the job day to day
- Your project is closer to a whole-home renovation or gut job alongside the addition
- You value a contractor with a flawless 5.0 rating and vetted subcontractor relationships
Pick Ace Build Contracting if
- Your addition or second storey needs heavy permit and inspection coordination handled for you
- You want documented liability coverage and licensing specifics upfront
- You're located in Mississauga, Etobicoke, Burlington, or Toronto and want a firm with direct experience in full-home extensions there
Verdict
For a home addition or second storey, the deciding factor is how much of the permit and structural process you want the contractor to own outright. Ace Build Contracting states this directly, with permits, inspections, and $5M liability coverage called out, plus a track record that includes full-home extensions, which maps closely to addition-scale work. Astaneh Construction is the stronger pick if you want a dedicated project manager driving daily communication and your project leans more toward a whole-home renovation than a pure structural add. Both score within half a point of each other, so this is a fit decision, not a quality gap.
