"Amanda was really very good!  At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it.  It was very clear that she knew her business and she gave me several ideas that I had not even thought about.  I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!

Basement Remodel FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

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

In addition to overseeing new home builds, construction managers work on large renovations and major remodels. For example, they may work with designers and oversee the construction of a finished basement, kitchen renovation, or a home addition. They may also oversee large-scale remodels, such as the update of a historic home. Construction managers step into small projects for more specific assistance, such as building budgets and compiling the team.

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!
