## The honest read

KA Building and Remodeling is a Waltham general contractor that's been finishing basements, building stairs and railings, and adding porches and decks since 1986, with Ken as the name reviewers keep coming back to.

In a May 2026 review, a homeowner credited Ken with turning their basement into a home gym, adding design touches they hadn't considered and even helping install an anchor plate on their deck. A December 2025 review described a full basement finish where Ken walked the client through the layout and the inspection process step by step, with a kitchen project already lined up next. Earlier reviews, from 2022 and 2024, describe the same pattern — thorough walkthroughs of the options and trade-offs before work starts.

A reasonable pick for a basement remodel or a smaller carpentry job — stairs, railings, a deck; ask for a couple of recent references before committing to a larger project.

**Strengths:**
- Basement specialist — gym and full basement builds praised
- Walks clients through it — options and inspections explained
