What recent reviews say

Groundworks earns trust through staff who explain work thoroughly, arrive on time, and leave basements and crawl spaces cleaner than they found them. Foundation repairs, waterproofing, and sump pump installs run smoothly; financing helps homeowners commit to fixes they have delayed for years. One reviewer noted sales pressure during initial consultation, though staff concern for their situation prevented losing the sale.

The company pairs thorough assessment with crew experience. Foremen like the team, the team, and the team manage complex repairs without delays or budget overruns. A homeowner found their severe foundation damage stabilized by the crew where other contractors had only suggested teardown and rebuild. Another verified foundation slope correction that competitors had missed entirely.

Most work centers on hardwood refinishing, repair, and installation rather than water damage restoration, though reviews confirm the team handles flood-damaged flooring well. Repeat praise goes to the team and the crew for staying in touch, showing up on schedule, pricing fairly, and leaving floors looking flawless and sites spotless. One unhappy client cited poor finishing technique, crew inexperience, and owner unavailability on their job, suggesting service quality may depend on which team member handles your work. Water damage jobs mentioned involved buckled kitchen floors and 1950s hardwood restoration after water exposure. The team replaced damaged sections, then sanded and stained the entire floor to match. Work is fast and priced reasonably, though warranty and long-term durability details do not appear in reviews.
