At the beginning of September this year Geico Builders started backyard renovation which is contains structural retaining wall about 220 lnf, pavers, composite deck Trex, staircase with beautiful fountain.

"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!"

"Every remodeling project comes with surprises, and ours was no exception. Instead of making excuses, Builders Group came up with practical solutions and kept the project moving. They were honest about costs, transparent about timelines, and handled every challenge professionally. That’s the kind of contractor you want on your side."

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"We needed an additional office space within our home. The concerns were removing an existing fireplace and hearth and replacing the hardwood floor to match what was already there, removing the chimney and patching the roof, moving a heating vent and again, patching the hardwood floors to match, adding an interior door, and moving lighting and electrical outlets. David was onsite everyday to either do the work himself or oversee the work by his subcontractors. They do quality work. The floors look great, the new wall is perfect, the roof was done well, the new interior door was installed well and looks like it was always meant to be there. Also, the work site was always cleaned up at the end of each work day. David is also very flexible, easy to communicate with, seems to truly care about your project, and works with contractors who do quality work."

Basement Remodel questions, answered by experts

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

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. 

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!
