Itemized · you approve every lineEgress Windows in Denver — common questions
Do I need an egress window for a basement bedroom in Denver?
Most CO codes require an egress window and well for any basement sleeping room. We size and install it to the requirement and coordinate the inspection.
Can you cut an egress opening in a poured foundation?
Yes — we cut, lintel, and frame the opening in poured or block foundations without compromising the wall, and document it in the scope.
Do I get a written, line-item estimate for egress windows?
Yes — you get a sectioned, itemized estimate before any commitment, so you see exactly what each part of the work costs. No lump sums, no surprise change orders.
Are OnSite crews licensed and insured?
Yes. Every OnSite crew is insured, bonded, and background-checked, and one accountable team stays with your project from the first estimate to the final walkthrough.
Do you offer financing?
Yes — financing is available through licensed lending partners, so you can spread the cost over time. It's optional and there's no obligation; we can set it up once your estimate is ready.
Is the estimate really free?
Yes. Your estimate is free and there's no obligation — we scope and price the work up front so you can decide with the full picture in hand.
