Why Houston costs more than the rest of Texas
Houston carries roughly a 8% premium over the Texas statewide figure. Three things drive that gap. Metro wages run above the state average, and labor is about 50% of this bill. Permitting and inspection are slower and more expensive inside city limits. And site access is tighter, which means smaller equipment, more hand work, and sometimes street permits for deliveries.
Statewide, Texas averages $6.06 to $12.12 per sq ft, against $6.54 to $13.09 inside Houston. Suburbs on the metro fringe usually fall between the two.

Permits in Houston
A residential permit for this work typically runs around $450 in Texas, and metro jurisdictions like Houston usually sit at the upper end of that range with longer review times. Permit cost is rarely included in a contractor quote, so add it separately. Confirm scope with the Houston building department before work begins.
Hiring in Houston
Get three written, itemised quotes from licensed and insured contractors, and make sure each specifies the same dimensions and the same grade of material. In a metro market, the cheapest bid often reflects a thinner specification or a crew travelling in from outside the area rather than a genuine saving. Ask for local references and check that the licence is current in Texas.
