Material selections can move the budget faster than anything else, with current material allowances landing around $1.02 to $1.70 per sq ft.
Labor complexity is the next major swing factor, with installation or trade time currently averaging $0.79 to $1.32 per sq ft.
Smaller consumables still matter, because supplies are contributing about $0.27 to $0.45 per sq ft.
Specialty tools, access equipment, cleanup, and disposal can add another $0.18 to $0.30 per sq ft.
Scope changes, premium finishes, difficult access, demolition, and permit requirements can push the total toward the high end of the range. Cleaner access, standard finishes, and bundled work often keep the job closer to the low end.
Get multiple itemized bids, ask contractors to separate materials from labor, and confirm what is included before you compare totals. Scheduling during a slower season and bundling adjacent work can also reduce mobilization costs.
Keep specifications tight before work starts. Change orders are one of the fastest ways to blow past the original budget, especially when material lead times or specialty trades are involved.
DIY can make sense when you already own the tools, understand the prep requirements, and can tolerate schedule risk. Hiring a pro is usually the better move when mistakes would affect finish quality, code compliance, waterproofing, structural performance, or warranty coverage.

Find a pro to do thisUse the calculator range of $2.26 to $3.77 per sq ft as your baseline, then compare that against the time, tool rentals, material waste, and rework risk you would take on by doing the project yourself.
Most install rigid insulation jobs start with site review, measurements, and material confirmation. From there the crew usually handles preparation, core installation or repair work, cleanup, and a final walkthrough to confirm the finished scope matches the quote.
Ask each contractor how they handle protection of adjacent finishes, debris removal, and change approvals. Those three points tend to separate a clean project from an expensive headache.
