"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."

"Everyone at Renovate was excellent to work with, communicated well, and obviously cared about doing quality work according codes and rules. Our project had a couple surprises (asbestos!), and we ending up spending more than we thought, but the whole team made it a positive experience, and we would love to work with them again on the next phase of our basement!"

"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."

"I highly recommend A to Z Remodeling We were looking to remodel our kitchen in a timely fashion. From our initial meeting with Shay was the Project Manager. He was alway available to lend a helping hand, answer our questions and concerns and very personable. To the following people on A to Z team we thank you. To Rick who did our framing and made the impossible happen. To Bruce who did our plumbing. To Anatoli for his expertise in tile work. And last but certainly not least Gary. Gary did our finishing work. He worked above and beyond our expectations. He has a work ethic like no other. All of these skilled gentlemen are an asset to this company. It was a pleasure working with each and every one of them."

Basement Remodel questions, answered by experts

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

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.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.
