Alesca stands out for pairing basement flood cleanup with detailed before-and-after photo reports on mold jobs in attics and crawlspaces.

• Detailed photographic before-and-after reports
• No hidden fees or pressure tactics
• Thorough containment and cleanup

Greg'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.

★★★★★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.

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

Services: flood water extraction, water damage restoration service

★★★★★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.

• Asbestos and vermiculite testing expertise
• Same-day or rapid scheduling
• Named technicians repeatedly praised for professionalism
• Large, well-established review base

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
• Named technicians praised for expertise and communication
• Full-service restoration from extraction through carpet replacement
• Insurance claim coordination included

★★★★★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

★★★★★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.

• Basement flood specialists
