Desa Contracting and Restoration
4.9 (92 reviews)score 89/100

Desa Contracting posts the strongest composite score in Markham on the back of 92 reviews averaging 4.9 stars, with reviewers repeatedly pointing to fast callouts and a clean, well-managed worksite. What stands out is the insurance handling: multiple accounts describe the team stepping in to coordinate with adjusters and even push back on slow preferred vendors to keep a claim moving.
- Fast response to water damage calls
- The team directly with insurance companies
- Clean worksite and attention to detail on ceiling and drywall repair
- IICRC certified, handles condo-to-finish restoration
Services: sewage cleanup, flood water extraction, structural drying dehumidification, insurance claims assistance
PuroClean
5 (126 reviews)score 84/100

PuroClean has the most reviews of any name on this list, 126 at a full 5.0 average, with a consistent thread of same-day arrivals and next-day material removal after basement floods. The confidence read is marked low despite the volume because the sentiment and recency sub-scores trail the top pick, so weigh the sheer number of positive reviews against a slightly less recent sample.
- Same-day on-site assessment for floods
- The team full insurance claim documentation and calls
- The team equipment and contractor scheduling
- Staff explain each step and keep to their timeline
Services: 24 7 emergency response, fire smoke restoration, sewage cleanup, flood water extraction
WINMAR Property Restoration Specialists - Markham
4.2 (37 reviews)score 66/100

WINMAR draws real praise for rapid emergency mitigation and strong project management, particularly when an experienced lead is assigned to the job. The 4.2 average across 37 reviews reflects a mixed record though: alongside the positive accounts is a smaller cluster describing unresolved damage and unresponsive project managers dragging on for months.
- Fast emergency mitigation crew
- Strong coordination on larger restoration projects
- Transparent insurance claim support
- Clear communication that reassures customers under stress
Watch out: A handful of reviewers report unfinished follow-up work and a project manager who went quiet for months.
Services: fire smoke restoration, insurance claims assistance, flood water extraction, sewage cleanup
RENOLUX RESTORE GROUP
3.8 (26 reviews)score 64/100

Renolux Restore Group gets called out for same-day dispatch and smooth coordination across multiple crews on bigger jobs, with some reviewers noting lower insurance quotes than the preferred-vendor alternative. The 3.8 average from 26 reviews is weighed down by a real pattern of billing complaints, so this is a case where the emergency response is solid but the invoice deserves scrutiny.
- Same-day emergency dispatch
- The team multiple crews on large-scale jobs
- Insurance partnership experience
- Quotes that reviewers found lower than preferred vendors
Watch out: Scope creep and unexpected charges come up often enough to ask for a full breakdown before work starts.
Services: fire smoke restoration, insurance claims assistance, flood water extraction, water damage restoration service
MapleTrust Restoration Inc
5 (2 reviews)score 62/100

MapleTrust Restoration shows up here on the strength of one detailed five-star review describing careful mold containment, clear explanations, and a safety-first approach. With only two reviews total the confidence rating is low, so this is a promising early signal on a specific job type rather than a proven track record.
- The team and certified
- 24/7 emergency response availability
Watch out: Only two reviews exist so far, both need to be weighed as an early signal rather than a track record.
Services: 24 7 emergency response, fire smoke restoration, water damage restoration service, flood water extraction
SoS2u Emergency Services Water Fire Mold
5 (1 reviews)score 51/100

SoS2u rounds out this list with the least review data of the group, a single five-star review and a composite score well below the others. It's included as an active emergency responder covering water, fire, and mold in Markham, but there isn't yet enough evidence to judge it against the more established names above.
- Single review on record is a perfect 5 stars
- The team water, fire, and mold emergency calls
Watch out: Only one review exists, so there isn't enough evidence yet to judge consistency or reliability.
Services: 24 7 emergency response, fire smoke restoration, insurance claims assistance, flood water extraction
