"Matrix Basements used a bait-and-switch tactic on us. Their rep, Christopher Powers, promised a detailed ceiling paint job?including cleaning debris, taping off areas, and handling wiring. Based on that, we signed a contract. But during the plan review, the project manager said none of that was included and even claimed he?d never heard of it. We were told Matrix doesn't clean, doesn?t tape, and won?t touch any wiring. We'd have to prep everything ourselves?or live with overspray and debris being painted over. I asked to cancel the contract, but Matrix stopped responding. Now we?re stuck with an open contract, out a down payment, and no work done. They won?t reply or resolve it. Avoid Matrix Basements if you want honest, reliable service."

Basement Remodel questions, answered by experts

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

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.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary
