How can I verify a contractor’s past work and reputation?

For commercial property owners, facility managers, and those responsible for the maintenance and restoration of sizable assets, verifying a contractor’s past work and reputation is critical. Quality commercial waterproofing and masonry restoration require extensive technical know-how, proper planning, and a history of successful projects, especially in New England’s challenging climate.

Begin by requesting a list of relevant completed projects. Look for work on properties similar in size, complexity, and construction type to yours, such as institutional campuses, municipal buildings, historic structures, or multi-unit condominiums. Reputable contractors should be able to provide detailed project portfolios and references for recent commercial work.

Contact several references and ask about their experiences. Inquire about the contractor’s communication, ability to solve unforeseen issues, adherence to safety protocols, and the long-term performance of completed work. It is especially important to ask if the work addressed water intrusion, structural protection, or historic preservation effectively, given the significant impact of New England’s freeze-thaw cycles, heavy precipitation, and salt exposure on building envelopes.

Review online resources such as industry association directories, public project bid results, and local trade publications for mention of notable projects or industry recognition. For public or institutional projects, you may be able to confirm contractor performance through procurement offices or state databases, which may list qualifications, compliance data, or DCAMM certification if relevant.

Examine the contractor’s technical approach. Experienced companies take time for thorough inspections, document existing conditions, and provide detailed restoration plans. They should also specify use of appropriate materials and manufacturer-approved systems suited to the building’s age, envelope type, and regional weather. If their recommendations are vague, cover only surface-level fixes, or lack references to long-term maintenance, this may signal inexperienced or commodity-focused contractors.

A reputable firm should also be transparent about licensing, insurance, and safety compliance. For complex or historic structures, inquire if the contractor can show prior experience with similar preservation challenges and awareness of the specific risks posed by freeze-thaw cycles, wind-driven rain, and other New England hazards.

Thorough verification safeguards your asset and supports long-term building performance, structural resilience, and water management. While past successes do not guarantee identical outcomes, demonstrated expertise, trusted references, and a process-oriented approach are strong indicators of a contractor’s capability and professionalism.
