A seemingly straightforward home renovation project for a New Jersey resident turned into a costly and time-consuming ordeal, underscoring the potential challenges of DIY improvements. Kaan Esendemir, an Enterprise AI Architect, aimed to modernize his aging garage with a budget of $500.
The garage, estimated to be over 70 years old, featured concrete block walls that were deteriorating and allowing water to seep in, alongside visible cracks and stains. Esendemir planned to skim coat and paint the walls himself, hire an electrician for additional outlets and security lighting, and have a professional apply a self-leveling concrete layer over the existing blocks to avoid a full concrete job.
He initially anticipated the project would take minimal time and cost around $500, with his own labor contributing to the savings. However, the project, which began in April 2025 after being conceptualized in late 2024, stretched over several months, with Esendemir experiencing a loss of motivation and the garage remaining unusable for an extended period. He finally completed the renovation in September 2025.
Unforeseen Costs and Labor Challenges
Esendemir encountered significant physical demands, completing only about 20 percent of the wall renovation himself before needing to hire professionals to finish the work. This reliance on external labor, combined with unexpected additions like cabinets and workbench elements, significantly increased the final cost. In New Jersey, professional installation of a new concrete layer over existing garage walls can range from $1,000 to $4,500, depending on the area and preparation required.
Ultimately, Esendemir spent over $2,000 on the project, far exceeding his initial $500 budget. This figure included electrical work, materials, labor, and the added garage features. He also incurred an additional $200 expense to improve the aesthetic and safety of the electrical work by concealing exposed wires.
Broader Renovation Trends
Esendemir's experience reflects a broader trend in the U.S. remodeling market, which remains robust at over $600 billion, according to Harvard University's Joint Center for Housing Studies. This sustained activity is attributed to an aging housing stock and a prevailing preference among homeowners to renovate rather than relocate, especially given current housing market conditions.
Experts also point to the "lock-in effect" as a contributing factor, where many homeowners with low mortgage rates are reluctant to move and face higher borrowing costs. Consequently, renovations become a more appealing alternative to purchasing a new home.
Despite the challenges, Esendemir ultimately found the completed project to be worthwhile, resulting in a cleaner, more functional garage space. However, he acknowledged underestimating the project's scope and offered advice to other homeowners: thorough advance preparation, potentially using AI renderings for visualization, detailed homework on contractors and materials, and avoiding purely cosmetic choices without considering practicality. He also stressed the importance of securing necessary labor before starting.
