Before any demolition or the first nail is hammered, a good home remodeling contractor has already done a lot of work for you. Denver, like most cities and communities has specific building codes that must be followed. In order to have any additions to or remodeling of your home, you need the correct permits.
Not only are reputable home contractors experienced at a wide range of home remodeling techniques, they also have contacts with other home improvement professionals you might need like plumbers and electricians.
Each contractor should have insurance and warranty information available to you. Typically contractors provide a one year warranty on material and labor, check with the contractors to verify the extent of any warranty extended to you.
Be sure to talk to and visit at least three previous clients and utilize the Better Business Bureau at http://www.denverbbb.org. You should also insist on proof that the contractor is insured and bonded. Check with the insurance company that the contractor's policy is current.
After selecting a contractor, get a written contract detailing the work to be performed, the costs associated with each task and a timeframe with estimated start and finish dates. Sign a contract that protects against liens from subcontractors and consider these additional tips for the completion of a good contract:
*Warning: Beware of unscrupulous contractors that suggest you, as the homeowner, secure the permit in your name. The permit holder is legally responsible for the completion of the job to code standards.
