Check reviews before requesting an estimate
Before contacting a local contractor, spend ten minutes reading their Google reviews. A trustworthy business usually has a rating above 4.2 stars and at least thirty recent reviews. Be cautious of perfect ratings with no written comments: they may come from questionable profiles. Pay particular attention to negative reviews to see whether the contractor responded and handled the issue professionally.
Check other reputable review platforms and local business listings too. If a contractor appears nowhere online, they may simply be new — but it is worth asking how long they have been operating and requesting references before you book.
Request at least three itemized estimates
A serious estimate should describe the exact work, quantities, material brands or references, labor separately from materials, and the expected schedule. Be wary of a vague total that gives you no way to understand what you are paying for or what happens if the scope changes.
Ask for every line item: an electrician should list the number of outlets and breakers, while a plumber should identify fixtures, pipework, and any service call charges. Compare three estimates on those details, not just on the final total.
Verify licensing and insurance
Ask whether the contractor holds the licenses, permits, and trade certifications required for the work in your area. For electrical, plumbing, structural, and other regulated jobs, the right credentials are a practical sign that the business understands the applicable safety standards.
Request proof of current general liability and trade insurance, plus a legal business name and registration details you can verify through your state or local registry. A legitimate business should provide a written estimate and invoice. Do not pay a large deposit to someone who cannot document who they are or how the work is insured.
