Maloney Construction Inc.

Maloney Construction Inc. provides specialized foundation services to residential and commercial clients across a wide range of counties, including Marin, Sonoma, San Francisco, San Mateo, Alameda, Solano, Mendocino, Lake, Sacramento, and Napa. Founded in 1996, the company has developed a reputation for solving complex foundation challenges, with a specific focus on helical pier installations and comprehensive foundation repairs. Led by Sean Maloney, Maloney Construction is committed to honest pricing and effective communication, ensuring clients are well-informed about the work required and the associated costs.

Maloney Construction’s project approach emphasizes direct engagement with clients, problem-solving, and technical precision. The company is particularly noted for its work with helical piers, which extend support to structures where traditional methods may fall short. This expertise enables them to address unique foundation issues, such as securing homes that are at risk of sliding downhill, a task that remains challenging for many contractors.

The company has achieved Diamond Certified status, reflecting its high ratings in Quality and Helpful Expertise. However, while this certification is a positive indicator, it does not eliminate the need for due diligence. Potential clients are advised to:
- Request a detailed project proposal, including load capacity tests and material requirements.
- Confirm the company’s licensing, insurance coverage, and relevant experience in specific project types.
- Engage in a thorough discussion about the costs involved, especially in relation to soil conditions and structural demands.


Maloney Construction’s commitment to transparency is evident in its approach to pricing. Unlike some contractors who may initially underbid and issue change orders later, Maloney Construction provides clear, upfront pricing based on a comprehensive assessment of the project. This ensures clients have a realistic understanding of the investment required to maintain and enhance their property’s structural integrity.

The company’s operational model includes personalized client interactions, with Mr. Maloney taking an active role in project oversight. This involvement ensures that quality control remains high, and clients receive the most effective solutions tailored to their specific needs.
