"RORHI completed our basement renovation. They did fantastic work, and all the contractors were highly professional: the framers, the insulators, the drywallers, the electrician, and the finishers. They went above and beyond to accommodate some special requests, like installing a commercial dehumidifier and finishing the walls of the storage closet, which were not part of the original scope, which greatly enhanced the finished look. We had a great experience working with Evan, Mike, and Matt (the initial estimator), as well as Inmer (finishes and framing), Eddie (painter), and the electrician. Despite minor miscommunications leading to necessary changes, they promptly addressed our concerns, sending someone immediately or the following day to resolve issues. Overall, we were impressed by RORHI's dedication and responsiveness, and we plan to hire them again for our next projects."

"We have been wanting to finish our basement for a very long time now but the prices we were given were too high! A friend of ours referred DCL to us and we thought we would give them a shot. The price was right so we started shortly after. They took care of all the paperwork and permits needed! Bob was there for the whole process discussing with us every step of the remodel! Very knowledgable and very well trained team! Our basement looks incredible and we enjoy spending time there! I would recommend DCL to anyone!!"

"Mike and the crew did an excellent job. Mike kept us informed, took care of getting necessary permits and worked with a plumber we hired to do other work on the house. The price was reasonable and Mike was able to make a few changes during construction at no additional cost to us. We are looking forward to working with Mike on other projects."

Basement Remodel FAQs, answered by experts

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
