Home Improvement Projects From a professional construction estimator: Make sure when you compare bids that you are comparing apples to apples. Go through each section to make sure the same work is being specified and the same materials. Some contractors like to give low bids and make it up in "extra change orders" which means changes to the original contract. If it's a large project, you'll most likely be seeing different subcontractors. Make sure these subs are quality contractors not the cheapest subs the general contractor could hire in order to make more profit. Anyone who's been around for a while shouldn't be doing these things but you'd be surprised what you run into. Quick Check List Before selecting a remodeling contractor, you should do the following: Plan your project from start to finish. Be specific in explaining exactly what you want. Be sure to approve any architectural plans that are involved before the contract work begins. Compare costs before making a financial commitment. Discuss bids in detail with each contractor. Ask the contractor for local references and find out if he or she is a member of a professional remodelers association. Contact your Better Business Bureau to learn how long a contractor has been in business. Find out if a contractor is insured against claims covering worker’s compensation, property damage, and personal liability. Check with state, county, or city housing authorities to be sure that a contractor meets all area licensing/bonding requirements.
