"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 Ridiculous, contract rescinded.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."

FAQs for basement remodeling projects in Portsmouth, NH

While the terms remodeling, renovating, and finishing are often used interchangeably, there are some differences. Remodeling your basement transforms the space by changing its layout, adding new features, or altering its function. Renovating restores the existing space to like-new condition without major structural changes. Finishing converts an unfinished basement into a livable area with walls, ceilings, and flooring.

A full basement remodel typically takes two to six weeks, depending on the project's complexity and any unforeseen challenges. Factors like design changes, permitting, and material availability can affect the timeline, as well as the availability of the contractors you’re working with. Remember that the bigger the project, the longer it will take to complete.

Remodeling your basement is not just about gaining extra space—it's a savvy investment. You can expect around a 70% return on investment (ROI), comparable to other major home improvements like kitchen or bathroom remodels. Adding functional living space boosts your home's value and appeals to potential buyers. Plus, converting your basement into a rental apartment could provide additional income, increasing your return even more.
