"We just wrapped up a full bathroom remodel with D2A Construction and I'm beyond thrilled with how everything turned out. From the very first consultation, Dani was straightforward, attentive, and genuinely listened to what we were hoping to achieve. Our bathroom was old, cramped, and honestly kind of embarrassing. Now it feels like a luxury spa — seriously! Dani's crew was polite, professional, and always cleaned up at the end of each day (which I hugely appreciated since we have little ones at home). The tile work is flawless, the new shower layout is so much more functional, and the modern design they suggested works beautifully in our space. There were a couple of small hiccups (as expected with any construction), but Dani handled them quickly and kept everything on schedule. We never felt in the dark. Can’t recommend D2A enough. It’s rare to find a contractor who communicates well and actually delivers what was promised!"

"I’m still in awe every time I walk into my new kitchen. 1 Degree Construction made what I thought would be a stressful project feel smooth and even enjoyable. They helped me reimagine the layout to make it more functional, and their designer had some brilliant suggestions I never would have considered. The project manager was super organized and kept things moving in a timely manner, even when there were minor hiccups with a delayed countertop delivery (not their fault). The whole team was friendly, polite, and clearly cared about doing a quality job. I’ve already recommended them to two friends."

The cost of home remodeling is $50,000 for the average homeowner. However, this cost can range anywhere from $3,000 for a small project to $170,000 for a whole home remodel. Factors like project size, location, and room type all affect your overall cost. For example, bedroom remodeling costs are one of the least expensive projects, costing about $1,500 to $5,500 per bedroom. However, a kitchen remodel has a significant cost range, totaling anywhere from $14,500 to over $70,000.
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Yes, most states require home remodeling contractors to be licensed, and for good reason. Hiring an unlicensed home remodeling contractor could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
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.
