Highlights
- Basement specialist — gym and full basement builds praised
- Walks clients through it — options and inspections explained
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.

Ken is awesome! He helped us build a new gym in our basement and it looks incredible. He had great ideas that we didn’t think of that made the final product much nicer. He even helped me carry some furniture upstairs and helped install an umbrella anchor plate on our deck. Ken is very nice and easy to work with. He will get the job done no matter how tough!

KA is awesome to work with. Fully finished our basement and helped with the layout and talked us through each step in the inspection process. Highly recommend using them for a remodeling. Looking forward to them redoing our kitchen as well!

They are very professional, thorough, and efficient. They walked us through all of our options and discussed the pro/cons of each one. They made sure we understood the work they were going to be doing and answered all our questions.
