At ContractorNearYou.com, we built our platform on a single, unwavering promise: to empower homeowners with the most accurate, hyper-local, and up-to-date home improvement information possible. Arguably, the most important part of that mandate is around setting contractor cost expectations when homeowners are in market to improve their home.
Relying on unspecific averages can be a recipe for budget disasters. Our proprietary estimation algorithm actively tracks micro-economic shifts, calculating cost multipliers down to the city and zip code level every single month to ensure you know exactly what to expect when purchasing contractor services near you or project materials, then rolling that up to the city, county, and state levels.
This month, our data revealed some notable upward shifts in several Counties in California. As labor demand for contractors near you and local economic factors fluctuate, certain areas are seeing the cost of home improvement projects rise faster than the rest of the state.
Here is a look at three examples of the top markets experiencing the largest month-over-month (MoM) cost increases, and what those percentages would actually mean for your wallet.
