1. Define the job before requesting bids
Write down what is failing, what outcome you want, the rooms or systems involved and any timing constraints. Contractors cannot price the same job if each receives a different description.
2. Confirm the company is real
Compare the business name, website, phone number and address across the company's own website, its public profiles and any contract it sends. Watch for newly created lookalike websites or a salesperson who refuses to identify the legal business.
3. Check the credentials the work requires
Colorado requirements can vary by trade and local jurisdiction. Ask which license, registration or permit applies to the project, then verify it with the relevant city, county or state authority. Do not accept a screenshot as the only proof.
4. Verify insurance directly
Ask for a current certificate of insurance and contact the listed agent when the project carries meaningful risk. The business name on the policy should match the company signing the contract.
5. Compare written scopes, not just totals
A useful estimate identifies materials, quantities, preparation, cleanup, exclusions, payment schedule, warranty and who handles permits. A lower number may simply omit work included elsewhere.
6. Read recent critical reviews
Look for patterns in complaints about communication, change orders, cleanup, warranties and unfinished work. One angry review matters less than the same problem repeating over time.
7. Control the payment schedule
Avoid paying the entire project before work begins. Tie payments to clear milestones and keep records of invoices, receipts, change orders and messages.
8. Get changes in writing
Verbal agreements are easy to misunderstand. Any change in cost, material, scope or completion date should be documented before the changed work proceeds.
9. Keep the final walkthrough specific
Create a punch list, photograph unresolved items and confirm how warranty requests should be submitted. Do not rely on “we will come back later” without a written plan.
Use directory rankings as a starting point
A strong rating and review history can help narrow the field, but it cannot replace verification and a clear contract.
