How much does spray foam insulation cost per square foot?
Spray foam insulation is priced per square foot after an in‑home assessment. A Milestone technician will inspect your Dallas-area attic and provide a no-cost written estimate before work starts. Final pricing depends on attic size, current insulation removal, target R-value, and any add-ons like air sealing, radiant barrier, attic access tents, or recessed light covers. If you call before 10 am, we try for a same-day appointment. Technicians explain options and costs on site.
- Price drivers: square footage, removal needs, R-value target, air sealing/accessories.
