"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 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."

"I couldn't be happier with the basement renovation completed by Gold Remodeling at our Kirkland home. before the remodel, the basement felt cold and unfinished. 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."

"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

Yes, you can add a kitchenette to a basement. However, you’ll have to consider the costs associated with basement kitchenettes. If you’re starting from scratch in an unfinished basement, you’ll need to account for brand-new plumbing, electrical, flooring, and more in addition to the cost of the kitchenette. If you’re putting a kitchenette in an already finished basement equipped with plumbing and electrical, you’ll save considerable money.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

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’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.
