"Tim and his crew are amazing. They built me an awesome deck!! From the beginning of the project to end I was thoroughly impressed. His quote was timely and fair. I’ve heard of so many horror stories about contractors so i was so pleasantly surprised at how great this experience was. The work began quickly and the workmanship is incredible. These guys know what they’re doing. Tim is so professional. He is prompt, he communicates everything in detail and really pays attention to detail in the work. He’s also a really nice guy. His crew is polite and work so hard. They’d get here and never stop working. Maybe 5 minutes to eat a sandwich. I plan to hire Tim for future projects. No question about it! Highly recommend."

"Did a wonderful job and takes pride in his work. He was adding a railing to the stairs and replacing stair treads and discovered problems with the raisers. Replaced those as well and provided a competitive price for the amount of work that was completed. We had specific concerns about having this done quickly. Gavin assisted in making sure that he was able to complete the stairs on time despite the additional work. We were happy with the work and outcome."

Basement Remodel FAQs, answered by experts

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

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.

While bathrooms and kitchens are nearly equal in terms of renovation difficulty, kitchens are the most challenging. Kitchen design, layout, electrical, and plumbing needs all depend on each other for the success of the entire project, and mistakes early in the project can cause trouble later on.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.
