★★★★★5 (49 reviews)score 87/100

Direct Waterproofing Inc holds a perfect 5.0 rating across 49 reviews, the second-highest score on this list. Every review over the past year describes the same result: leaks found, foundations sealed, and basements staying dry through storms afterward, with clear explanations and fair pricing along the way. This is the pick for a wet or musty basement rather than a fresh flood emergency.

• Consistent long-term results, basements stay dry after storms
• Honest, transparent pricing
• On-time arrival and thorough cleanup
• Deep experience with foundation cracks and seepage

★★★★★5 (126 reviews)score 84/100

PuroClean carries the largest review base on this list at 126 reviews and a 5.0 average, with reviewers describing same-day assessments and next-day removal of wet materials. Staff handle insurance calls directly and document the work for claims, which speeds up the process. The composite score sits a bit lower than the raw rating would suggest because recency and verification data lag behind the review volume.

• Same-day on-site assessment for floods
• Full insurance claim handling
• Next-day removal of wet materials
• Courteous crew that explains each step

Services: flood water extraction, 24 7 emergency response, fire smoke restoration, structural drying dehumidification

★★★★★5 (4 reviews)score 71/100

On Side Restoration Services has just four reviews on record, all five stars, describing efficient sewage cleanup and water damage work with minimal disruption to the property. That's a small sample, but what's there is consistently positive on professionalism and timeliness.

★★★★☆4.2 (37 reviews)score 66/100

WINMAR's Markham location carries a 4.2 rating across 37 reviews, with plenty of praise for fast emergency mitigation and strong project management on bigger jobs. A portion of reviewers describe follow-up lapses and unresponsive project managers that left repairs unresolved for months, which pulls the sentiment score down from where the initial-response reviews alone would put it.

• Fast emergency crew deployment
• Experienced project managers on larger jobs
• Clear communication during the initial response
• Insurance claim support

Services: flood water extraction, fire smoke restoration, insurance claims assistance, sewage cleanup

★★★★☆3.8 (26 reviews)score 64/100

Renolux Restore Group earns praise for same-day emergency dispatch and coordinating multi-crew jobs, with some reviewers noting its insurance quotes run lower than preferred-vendor pricing. Its 3.8 rating across 26 reviews reflects a real split, though: a cluster of complaints centers on unexpected charges and scope disputes once work is underway.

• Same-day emergency response
• Coordinates multiple crews on large jobs
• Insurance partnership experience
• Quotes can run lower than preferred vendors

Services: flood water extraction, fire smoke restoration, insurance claims assistance, water damage restoration service

★★★★★5 (2 reviews)score 61/100

MapleTrust Restoration Inc has only one review on file, a five-star account of mold containment work that praises clear explanations and safety-focused containment. That's not enough evidence to rank with confidence, but the one detailed account is a genuinely good sign.

• Professional and efficient on-site
• Thorough containment and cleaning

Services: 24 7 emergency response, fire smoke restoration, flood water extraction, water damage restoration service

★★★★★5 (5 reviews)score 57/100

FixMastersGTA has five reviews, all five stars, but they describe drywall repair, painting, tile, and bathroom renovation work rather than water damage mitigation specifically. It reads as a capable general contracting crew by those accounts, just without direct evidence yet on flood response or drying work.

• Professional, efficient crew
• Attention to detail on finish work

Services: flood water extraction, water damage restoration service

★★★★★5 (1 reviews)score 51/100

SoS2u Emergency Services Water Fire Mold has a single five-star review on record, which isn't enough to build a reliable read on consistency. The name points to combined water, fire, and mold emergency coverage, but there isn't yet a track record of reviews to back that up in Markham.

• One review on file rates the work five stars
• Positions itself as a combined water, fire, and mold emergency responder

Services: flood water extraction, 24 7 emergency response, fire smoke restoration, insurance claims assistance

score 32/100

Unionville Property Services has no Google reviews yet, so this listing rests on the company's own claims: licensing, insurance, and seven-day-a-week availability for water extraction and structural drying across Markham and York Region.

• Says it's licensed and insured
• Offers emergency water extraction seven days a week
• Structural drying and dehumidification services listed

• Says it operates seven days a week

Services: fire smoke restoration, flood water extraction, insurance claims assistance, sewage cleanup

score 28/100
