3. Rostica Renovations
5 (52 reviews)score 89/100
Rostica stands out for an engineering-minded approach and in-house millwork, which reviewers say lets Emin's team take on custom requests that other contractors turn down. Support doesn't stop at handover either: the team is credited with resolving issues years after project completion.
- Engineering-minded design and problem-solving approach
- In-house millwork cuts costs and delays
- Long-term warranty support after the project wraps
- Keeps noise and mess to a minimum on-site
Watch out: Review volume (52) is solid but smaller than the top two, so the sample is a bit thinner.

5. BuilDMaker Renovations
4.9 (31 reviews)score 80/100
BuilDMaker earns strong praise for Marcos's tile and marble installation, with most reviewers highlighting on-budget delivery and respectful conduct in occupied homes. One serious 2021 incident involving water damage and a dispute over liability is worth weighing against the otherwise positive record.
- Expert tile and marble installation
- Punctual and budget-conscious on most jobs
- Strong subcontractor coordination and advice
- Attentive to fine detail work
Watch out: A 2021 water damage incident and the owner's refusal to involve insurance left a client displaced for over two months; ask directly about liability coverage before signing.

6. GiGi's Home Improvements & Renovations
4.6 (9 reviews)score 63/100
Luigi's work draws consistent praise for craftsmanship and honest pricing among repeat clients, though the review base is small and hasn't picked up recently. Recent reviews read as consistently professional even though one early estimate request reportedly went unanswered.
- Meticulous attention to detail
- Honest pricing and straightforward advice
Watch out: Only 9 reviews and no recent activity, plus one complaint about an unanswered estimate and a rocky initial site visit.
