"Signed contract on May 8 for deck build.On May 12 rep came to my office to collect deposit of apprx $13,000. He said project team meeting on Wed & would update me then on start date etc. On Fri May 16 I had to reach out to him. He wrote the team had met & materials were ordered. An hour later he wrote back that he was misinformed & that his boss was going to call me next week. Despite this, dep check cashed. On Mon 5. 20 rep wrote back that they had forgotten certain costs & to proceed it would be $8,000 more. Not a typo. $8,000 more. No apology. Ridiculous, contract rescinded. I wrote that he could return my deposit at my office just as he had collected it. On Wednesday the 21st I got a text from "Tom," presumably the owner/boss, saying he would "drop a check in the mail" to my address. Today is May 30th, Friday, and still no check. Check at a minimum should have been overnighted. They owe me interest not to mention the deposit to hire a contractor who will honor contract. Bad."

Basement Remodel questions, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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. 

Assuming you are going for a full remodel for an average-sized basement with a reputable contractor, the process can take up to two weeks or more. Remember that basements have many stairs and often difficult access—it’s not like working in the entryway. The shuttling of materials, increased need for ventilation and safety precautions, and making sure everything can be removed through a doorway all increase time and cost.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.
