"We hired Skytech Builders to renovate our kitchen and bathroom, and they sent Leo to manage the project. From the start, he was fantastic—an excellent communicator who really listened to our needs and took detailed notes during the entire consultation. Once we decided to proceed, Leo guided us through the material selection process, making everything run smoothly. Overall, it took about a month to plan and another month to complete the construction. We're thrilled with the results and will definitely reach out to them for our next project."

"We were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

Overall i would most likely hire them for further jobs."

"My partner and I have had the pleasure of working with Dan, David and the hardworking crew at LB Construction & Remodeling for our what is now an extensive home restoration and renovation project. I cannot express how thrilled I am with the results thus far. From start to finish, their team demonstrated an unparalleled level of knowledge, speed, and attentiveness that truly exceeded my expectations. Truthfully, I didn’t know where to begin with my project, so I was very happy when Angi.com recommended LB. Dan responded quickly and was able to meet me at the house and walk the entire site with me. I had recently purchased my house and it needed extensive repair from years of water damage, including repair and replacement of the wood framing, installation of proper drainage, and foundation work. What truly set Dan and team at LB Construction & Remodeling apart was their willingness to help me hash out the details and various plans for our projects. Dan and David patiently worked with me to explore different options, providing valuable insights and recommendations based on their extensive experience, such as navigating permitting, advising on order of operation. This collaborative approach made me the decision-making process easier and less stressful as I had never done anything like this before. The speed at which LB Construction & Remodeling worked on my projects was truly impressive. They efficiently managed their time without compromising on the quality of their work. Every step of the way, it was evident that they were dedicated to completing the project promptly, ensuring minimal disruption to my daily life. Not to mention their attention to detail and commitment to quality craftsmanship were evident in every aspect of the projects, particularly with the reframing and painting. One of the standout qualities of LB Construction & Remodeling is their exceptional attentiveness. Dan consistently paid close attention to my needs and concerns, making me feel valued as a client. An example of this was when I communicated how I wanted the trim around the windows to look, both inside and out. I sent Dan pictures to illustrate what I was expecting, and he listened to me, verified specifics of my ideas, and walked me through how they would be able to achieve the look easily. Their work was seamless and they captured my vision perfectly. Right from the get-go we felt a sense of trust with Dan and team and that really helped make this entire process enjoyable. I wholeheartedly recommend LB Construction and Remodeling to anyone seeking a trustworthy and skilled team for their home improvement needs. I am eager to continue our other home projects with LB Construction & Remodeling in 2024."

Basement remodels FAQs
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.
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.
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
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.
