"Vic Johnson and his crew were extremely knowledgeable about construction in general, friendly and accommodating throughout the entire process answering a multitude of questions, pivoting when needed, helping educate us homeowners of the hows and whys, and bending over backwards to make things right...when work wasn't going to plan (and remodels never go perfectly as planned). They were fair, and provided an enormous value. I'd highly recommend Johnson and Sons for any remodel you may have."

"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 completed an extensive basement remodel in our 1924 home. The basement work included new framing/drywall, windows (including a large egress window), plumbing and electrical to support a main living space, new bathroom and new laundry room. We also updated our old forced-air HVAC and water heather to new mini-splits and a tankless water heater. This is our second major project with Ryan and we plan to work with him for many years to come. He's incredibly responsive and detail oriented and always plans phases of our projects to support our future plans. Ryan's expertise and quality of work is well worth the cost."

Basement Remodel questions, answered by experts

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

In addition to overseeing new home builds, construction managers work on large renovations and major remodels. For example, they may work with designers and oversee the construction of a finished basement, kitchen renovation, or a home addition. They may also oversee large-scale remodels, such as the update of a historic home. Construction managers step into small projects for more specific assistance, such as building budgets and compiling the team.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Kitchens and bathrooms are typically the most expensive rooms to renovate. The high cost is due to several factors, including expensive appliances like ranges, hoods, and refrigerators, as well as costly fixtures. The 'bones' of the room, such as electrical and plumbing, are also expensive to move or replace. Because of the vast amount of prep work, finishing, and specialized labor involved in a relatively small footprint, these projects can cost double or more than a living space remodel. Even when trying to renovate on a budget, kitchens and bathrooms will likely carry a hefty price tag.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.
