With over 40 years combined experience, we provide complete Basement remodeling and finishing services with Free estimates and no-nonsense pricing. We will give you the Basement you've always wanted by transforming your previously unfinished Basement into a usable and comfortable living area you can be proud of. We are known for constant communication and on-site project management.

"Our experience with Basic Basements was great from start to finish. Gail, the scheduling coordinator, was very responsive and helpful every step of the way keeping us informed about what work was going to be done next. John, our project manager, was great and made sure all the work was completed efficiently and on time. The work crews coming in and out were outstanding. They were very respectful of our home, worked nonstop until the work was finished, and did an excellent job cleaning up every day. The biggest, and only, headache we encountered was waiting for inspections from our town, which is completely out of Basic Basements' control. We are very pleased and would 100% use them again."

Second story addition building services FAQs

Many homeowners find adding a second story a worthwhile investment. It significantly increases their home's value and provides more living space to enjoy. It’s especially beneficial for homeowners with a limited lot size who want to add square footage without building out. 

The time required to build a second story depends on the size and complexity of the project. While most additions are completed within two to six months, some larger or more intricate designs may take up to a year. The permitting process, weather conditions, and material availability also affect the timeline.

Your budget, location, and lot size will determine if it’s best to build up or out. If you live on a lot with limited space, building up allows you to add square footage without taking up additional ground space. Building out is often best if you live in an area with zoning restrictions or want to live in your home while it’s under construction.
