"We had water loss in our house. In addition to the restoration work, we decided to do a broader remodel at the same time. We actually hired a different company that promised to make our house all new again, but we had a lot of delays and communication issues, and ultimately walked away from that company. We had already moved into temporary housing for the remodel, and needed another contractor to step in quickly. Johnson and Sons rose to the occasion and were able to get us back into our house quicker than the first company would have. Our remodel was basically the whole house. Floors, interior paint, all 3 bathrooms and the kitchen. The price was competitive. The timeline was good. The communication was outstanding, which was very important to us. Vic was always available to answer questions and proactive in letting us know what was going on. Jon and Tony were patient and willing to make adjustments as requested. We did discover an issue based on a previous contractor's faulty work, but Vic was quick to explain the situation and give us options and prices. We would definitely recommend them to others."

"JJ construction was my #1 choice for remodeling. I made my appointment with JJ construction. The person showed up on time and very thorough. We were very pleased by their expertise and their advice. However, I decided to sell the house as is. No work was done on my house. But I do recommend this company for future projects."

Now it's a comfortable space where our family spends time every day. the craftsmanship throughout the project was impressive, from the custom built-ins to the flooring and trim work. the crew worked efficiently and maintained excellent communication from start to finish. everything was completed with care and attention to detail. if you're considering a basement remodel, Gold Remodeling is absolutely worth calling."

"I hired Topaz Remodeling to replace my front porch, including tearing out the damaged surface, installing a proper drain (the original builder’s oversight caused major leaks), and repairing the resulting damage to the floor, hardwood, and basement. The owner’s communication was excellent, keeping me informed about schedules and progress. They even finished ahead of the estimated timeline. Omar, the project lead, was phenomenal. His recommendations elevated the final result, and his attention to detail was unmatched. The tilework is flawless, with precise measurements ensuring a polished look. The team delivered exceptional quality, turning a stressful situation into a seamless process. My new porch is beautiful and fully functional. I highly recommend Topaz Remodeling and will gladly use them again for future projects."

"I am very pleased with Renovate Construction. The original project was to completely redo one bathroom (replace existing fixtures in the same place) and add a shower to a very small half bath. During the project we discovered a few additional things that needed to be fixed (a gap in siding on the outside of our half bath was causing a leak, a leaky window in the basement meant that we needed to redo the drywall downstairs, and I asked to replace carpet on the upstairs with hardwood plus repaint the stairwell), and they were helpful and reactive to each new project. Everyone, whether the Renovate Construction crew or a subcontractor who worked on the project, was very good at their job. There were a few small mistakes, and they were fixed with no issue. Additionally, every person that I interacted with was professional, but more than that, they were nice to be around! That is so important when a crew is working in and around your home for weeks on end. Our project ended up being bigger than I had initially planned, for the reasons above, but the team stayed on time, on budget and in good contact with me throughout the process. I am pretty picky about fixtures and things, and they worked with me when I wanted some very specific tile, a customized sink, asked them to install vintage or Ikea elements, etc. We were having separate electrical work done at the same time, and they did a great job of coordinating with them as well. I loved their ideas and their work; I would definitely work with Renovate Construction on another project. I'm already dreaming of what my new kitchen will look like."

"Ryan and his team did a great job on our basement remodel. Communication was strong as was attention to detail. A concerted effort was made to keep the worksite clean. Like many renovations, it took longer than anticipated and we encountered a measurement hiccup that, while solved, could have been identified and addressed upfront"

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.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

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.

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.

Home improvements that increase value offer a high return on investment (ROI) and can enhance your quality of life. Upgrades to your home’s curb appeal often add the most value, with garage door replacement having one of the best ROIs at 93%. Other high-value exterior projects include replacing your front door, upgrading siding and roofing, installing a stone veneer, adding new windows, and landscaping. For interior renovations, a fresh coat of paint provides an excellent ROI. Major projects like a kitchen remodel or upgrading appliances and HVAC systems also add significant value, as potential buyers appreciate the peace of mind that new equipment provides.
