Questions to ask before you hire in Livonia
The answers matter more on Livonia's older housing stock than any star rating.
- Are you licensed in Michigan, and what is your license number?You can verify any Michigan residential builder or maintenance-and-alteration license in the state LARA database before you sign.
- Is the cause groundwater, surface water, or a sewer backup?The fix is different for each. A contractor who diagnoses before quoting is a good sign; a one-size quote is not.
- What exactly does the warranty cover, and is it transferable?Get the transferable-vs-not answer and the exclusions in writing. A warranty is only worth the paper and the company behind it.
- Can you provide three recent local references?Nearby, recent jobs on similar older homes tell you more than a star rating. Ask to see the work.
