"I have remodeled 5 homes and built one. With all my experience with contractors and subcontractors, I have never found one as reliable as Carson. He has helped my family with repairing older beach homes for the last three years. We have hired Carson to do a lot of jobs. He has completed all of them in a timely manner, using salt water resistant materials that will stand the test of time, and the end product demonstrates excellent craftsmanship. He helps us make decisions from 200+ miles away, staying on budget but producing excellent results. We haven't had to stress about overseeing the job as Carson treats our house as his own. We are beyond thankful for him, his team, and his attention to detail. My great grandfather built one of the homes in the 1950's and its withstood many Hurricanes. I'm so thankful that Carson can carry the tradition of excellent craftsmanship to our special place. As for specifics of this job, he built beautiful shiplap in our den, repaired our deck, replaced a rotten support beam with plumbing and electrical running through it, and painted our porch and deck. He did an incredible job."

"I've used cransten for two major projects now, first a partial basement finish and now installing built-in shelves and fireplace in my living room. Super super easy to work with, reasonably priced, the contractors they send out are communicative and professional. I can't say enough great things. I'll be back again when I'm ready for the rest of the basement to be finished."

"Quality of work seemed high until parts of floors came unglued, grout chipping in shower, areas missed paint in garage. 6 week project turned into 10+ weeks, WAY OVER PRICED! Sometimes workers wouldnt show the entire week. Had to have dry wall workers come back multiple times because they didn’t take mirrors or towel racks down just worked around them. Workers were nice and polite when at the house. Tons of miscommunication between myself and contractor. Very frustrating remodel job."

"They repaired the kitchen floor after a serious leak as well as repaired and replaced the subfloor foundational wood beams. We were stuck because we had to have the work done prior to an appraisal of the house in a week. Surprisingly they were able to move quickly and help us out. We were delighted with the professionalism of Chip and his foreman and all the workers! We were happy to share the house with them for a couple days and very pleased with the final work."

"My bathroom remodels performed by Intelligent Home Services were the best contractor experience I’ve ever had. They performed the work on schedule, were extremely communicative throughout the process giving me daily updates on work to be performed and when to expect the craftsmen to show up, and performed quality work all for a great price. They were even there for me when unexpected water damage due to my upstairs neighbor’s pipe led to me having to jump right into a master bathroom remodel one week after finishing the spare. The tile and drywall work were impeccable. Ben, the owner and licensed contractor, stayed involved throughout the process and made frequent visits to check out the work. I am a professional engineer who works with contractors regularly so I know good project management and construction services when I see them. If you’re looking for a contractor with knowledge and integrity who can perform quality work quickly and for a great price, then look no further."

Basement Remodel FAQs, answered by experts

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.

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.

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!

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.
