"This project was for three bathroom remodels in a 1960 single level ranch - the bathrooms hadn't had much updating.  There was extensive wallpaper in two of them which had to be removed (this is a terrible job!) followed by wall prepping.  The powder room proceeded without any problems and was done quickly. The guest bath required a few changes that were unexpected, such as moving the door frame to accommodate a 32" tub instead of the 30" originally in place, and moving the vanity light box.  Greg and Donnell were always happy  to do whatever I wanted, and offered advise and tips along the way when unexpected things came up. 
The en suite bathroom was a big mess from extensive water damage that we didn't know about.  When Greg took down the tiles parts of the wall completely collapsed from water damage (and everything looked great on the outside).  The wood beams were rotten, the sub floor under the shower tray was rotten and almost completely unsupported, and once Greg removed the tile flooring we realized that all of the sub floor had water damage and needed to be replaced.  Greg was suspicious and went into the crawl space under the house to determine if additional damage was evident, and it was.  This is a 1960 ranch house that has a strange support structure with support beams further apart than is typical.  The entire bathroom was essentially unsupported with the exception of two screw jacks in place (we knew about this from the home inspection but it wasn't clear the extent of previous damage).  Greg built an entire new support structure under the bathroom & shower.   As an add on we had Greg insulate our water pipes and replace some of the fiberglass insulation under the house.

I was so pleased with the work and the overall attitude of Greg and Donnell that I decided to have them install two new skylights.  Right after purchasing the house I tried to have skylights installed but was told by the contractor that he couldn't install them because the HVAC ducts were in the way (they are flexible plastic, not metal).  When I mentioned this to Greg he laughed and said of course the ducts could be moved, they're flexible and extenders can by installed if necessary (it wasn't).  Now I have two beautiful skylights thanks to Greg & Donnell!

Overall I really appreciated the communications between Greg, Donnell, and me.  We typically used text messaging which I find very convenient, and they could send me photos along with questions while I was at work.  I am a bit of a control freak and Greg and Donnell were OK with my need to know what was going on, and immediately if problems arose.  I plan on having them back in the early winter to replace an ugly stone fireplace facing and do some work on my kitchen."

Basement Remodel FAQs, answered by experts

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

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

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.
