"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."

"J J Construction owner Khoa Ha completely replaced my upper and lower decks with composite. He solved many problems we were facing with the decks and designed a system to deflect rain water away from the house. The upper deck was 48'x12' and the lower deck 14'x21', also replaced existing stairs, added bench seating. and lights. In addition he also repaired/reflashed metal roof on the lower back of the house and address foundation concerns. His team were great to work with, hard working, professional and courteous. We could not be happier with the results of this 4 week project. I highly recommend J J Construction for any project. We will be using him on future projects as well such as house painting, and some interior remodeling in the coming year."

"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

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

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. 

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.
