## The honest read

Knollmeyer Building Corp. is a North Andover general contractor established in 1991, working across commercial and institutional construction, restoration, building-envelope repair, roofing, masonry, waterproofing, renovations, and construction management. Its own site says the company has completed more than 2,857 projects and lists historical building restoration, concrete repairs, parking-garage waterproofing, historical roofing and masonry, interior fit-outs, and new construction among its services.

The company has a substantial construction history and appears on project and industry pages as a general contractor. A 2018 Banker & Tradesman report named Knollmeyer as the general contractor for a 111-unit East Boston development, while IIBEC reported that the company hosted a New England chapter event in North Andover. Its Google profile is 3.4 stars from five ratings, and the two quoted reviews are both one-star comments: a January 2026 reviewer said, “I'd seek elsewhere,” while an October 2022 reviewer called the company disrespectful to the surrounding community.

Ask for references and a detailed written scope for the specific restoration, envelope, roofing, masonry, or waterproofing work under consideration, particularly where the project involves occupied buildings or complex coordination. The company is best suited to owners seeking an established commercial or institutional contractor with broad building-envelope and renovation capabilities; confirm the project team, schedule, and responsibilities before signing.

**Strengths:**
- Long operating history — established in 1991
- Broad construction scope — restoration, roofing, masonry, waterproofing
- Project scale — reports more than 2,857 completed projects

**Concerns:**
- Recent review — January 2026 reviewer said they would seek elsewhere
- Community concerns — October 2022 review cites disrespectful conduct
