Best water damage restoration companies in Hamilton
This list ranks Hamilton's water damage restoration and basement waterproofing companies by their earned composite score, built from rating, review volume, recency, and sentiment (see our methodology). Most of these businesses cover the full range of the job: basement waterproofing, sump pumps, mold remediation, and emergency flood extraction, so they're ranked together as one list rather than split by narrow specialty.
Fire and smoke damage cleanup is judged separately, since it calls for different equipment and expertise: see our best fire & smoke damage restoration list. A few names below do fire rebuilds too, but they're ranked here on their water damage and waterproofing track record.
Picks are ranked by score and relevance to water damage restoration service, so a lower overall score can rank higher here.

Aquatech Basement Waterproofing Hamilton
5 (114 reviews)score 92/100
Every one of Aquatech's 114 reviews is five stars, and several customers report their waterproofing systems still performing well over a decade later. It's a solid choice for homeowners who care less about speed and more about a fix that actually lasts, backed by fair, transparent quoting.
- Same-day or next-day quotes and scheduling
- Transparent, detailed pricing upfront
- Thorough site cleanup after work
- The team verified still dry years after installation

Alesca Inc
5 (70 reviews)score 90/100
Alesca stands out for pairing basement flood cleanup with detailed before-and-after photo reports on mold jobs in attics and crawlspaces. Reviewers describe same-day quotes, work starting within 24 hours, and pricing that holds close to the original estimate. The review base is smaller than the names above it, so treat it as a strong but slightly less proven pick.
- Same-day quotes and site visits
- The team photographic before-and-after reports
- No hidden fees or pressure tactics
- Thorough containment and cleanup
Services: fire smoke restoration, flood water extraction, mold remediation, water damage restoration service
Absolute Mould Remediation Ltd.

Work spans basements and attics across older housing stock, with a personal, follow-up-driven approach.
- Family-run with deep mold remediation expertise
- Transparent communication from quote through completion
- Spotless cleanup plus prevention guidance

The Hamilton Plumber
5 (47 reviews)score 87/100
The Hamilton Plumber earns praise for arriving within hours of an emergency call, even evenings and holidays, and for backing up estimates with video proof of the work. The team technicians get repeat mentions for troubleshooting tricky jobs like main sewer backups and frozen pipes.
- Emergency response typically within 1-2 hours
- Fair, transparent pricing
- Video documentation of the work performed
- The team technicians available for follow-up
Watch out: This is primarily a plumbing outfit, so water damage work sits alongside general plumbing rather than being a dedicated restoration specialty.
Services: flood water extraction, water damage restoration service
Greg's Plumbing and Heating Inc.
4.7 (270 reviews)score 85/100
The team's has the largest review base on this list by far, 270 reviews at a strong 4.7 average, with most customers reporting quick dispatch and fair rates on water heater, drain, and fixture jobs. That scale is a real advantage, though it comes with an occasional service gap worth knowing about.
- Fast, often same-day dispatch
- Staff troubleshoot extra issues without upcharging
- Service calls include the first hour of labour
- The team, well-established track record
Watch out: One reviewer reported a fixture that leaked shortly after installation and difficulty getting a follow-up response, so confirm warranty terms on installation work.
Services: flood water extraction, water damage restoration service
Classic Basement Waterproofing Hamilton
5 (28 reviews)score 85/100
Classic Basement Waterproofing keeps a perfect five-star record across its reviews, with customers describing quick, tidy work at reasonable prices. It's a good fit for a straightforward basement leak or patch job rather than a large-scale waterproofing overhaul.
- The team on schedule
- Fast turnaround on repairs
- Thorough cleanup after the job
- The team, fair pricing
Watch out: Its review count is smaller than the top names on this list, so there's less history to judge it against.
Services: flood water extraction, water damage restoration service
Renotown
4.9 (32 reviews)score 84/100
Renotown handles the rebuild side of water damage as much as the cleanup, coordinating subtrades and restoring homes to like-new condition in a matter of weeks. Insurance companies assigning them jobs directly is a meaningful trust signal, and reviewers single out named project managers for staying reachable throughout.
- Insurance companies assign jobs to them directly
- The team managers available for every call
- The team typically completed in weeks, not months
- The team subtrades like flooring and asbestos removal without markup friction
Services: flood water extraction, fire smoke restoration, water damage restoration service, insurance claims assistance
RCC Waterproofing Hamilton
4.5 (93 reviews)score 80/100
RCC gets consistent praise for crews who show up, explain the work clearly, and finish basement waterproofing or foundation crack jobs within one to two days at prices customers call competitive locally. The composite score is pulled down by a real pattern of complaints earlier in the sales process, so it's worth knowing before you call.
- Transparent, detailed pricing
- Fast completion, typically 1-2 days
- Thorough site cleanup
- Same-day response to quality concerns once work starts
Watch out: A number of reviewers describe slow initial estimates and spotty communication before the job begins, so push for a firm timeline upfront.
Services: flood water extraction, water damage restoration service
Restoranation Environmental Services Inc.
4.9 (170 reviews)score 88/100
Restoranation covers ground most competitors don't, combining asbestos and vermiculite testing with mold and water damage work, and 170 reviews back up a pattern of prompt, fairly priced service. The team technicians get repeat praise, though one recent review describes a job that fell short on execution and follow-up.
- Asbestos and vermiculite testing expertise
- Same-day or rapid scheduling
- The team technicians repeatedly praised for professionalism
- The team, well-established review base
Watch out: One recent review describes incomplete asbestos containment and trouble reaching the business afterward, so ask how they handle post-job concerns.
Services: flood water extraction, mold remediation, water damage restoration service, insurance claims assistance
First General Hamilton
4.3 (65 reviews)score 76/100
First General handles the parts of a flood that go beyond drying: content packing, furniture storage, and carpet replacement, with named staff praised for responsiveness and insurance coordination. Its composite score sits lower than others here because of an assessment dispute that dragged on, worth factoring in.
- Rapid emergency response
- The team technicians praised for expertise and communication
- The team-service restoration from extraction through carpet replacement
- Insurance claim coordination included
Watch out: One homeowner felt a damage assessment didn't reflect their property's actual condition and communication on it was slow to resolve.
Services: 24 7 emergency response, flood water extraction, structural drying dehumidification, water damage restoration service
Pro Waterproofers
4.8 (42 reviews)score 71/100
Pro Waterproofers gets real praise for sharp diagnostic work and crews who finish on schedule and within quote. But sentiment here is mixed rather than uniformly positive, and the composite score reflects it, so this pick carries more risk than the others on this list.
- Thorough, knowledgeable diagnosis
- On-time work completed within the original quote
- Fair pricing
- Quick initial inspections
Watch out: Two reviewers describe a coating that failed to stop water intrusion and weeks of unresponsiveness on warranty and insurance paperwork after a $12K job.
Services: flood water extraction, water damage restoration service
SERVPRO of Hamilton, Mohawk
5 (5 reviews)score 70/100
SERVPRO's local branch gets uniformly positive marks from the reviews it has, with customers describing fast response and stress-free basement flood drying. The sample is just five reviews, though, so treat this as a promising but lightly tested option compared to the rest of this list.
- Same-day response to emergencies
- Basement flood specialists
Watch out: Only a handful of reviews so far, so there's much less of a track record here than the other names on this list.
