WINDOWS
Energy-efficient window upgrades
Plan window upgrades around the complete assembly’s certified thermal performance and the home’s exposure. Compare glass packages, air sealing and frame choices without promising a fixed energy-bill reduction.
START WITH THE DETAILS
What goes into
the work.
Measure each opening separately in inches, at multiple points. Record operation, installation height and frame condition. Coastal field-verifies order sizes.
Typical scope to confirm
- Review current windows and comfort concerns by room
- Compare certified U-factor and solar heat gain data for the climate
- Select glazing and air-seal details compatible with the product
- Record exact series and glazing configuration
Make it specific to your project.
Enter the amount of work and choose the details you know. Your choices follow you into the Project Builder.
LOW / MIDDLE / HIGH REFERENCE
Low$400per opening
Middle$1,200per opening
High$2,000per opening
Low and high are published reference endpoints. Middle is their arithmetic midpoint, not a quoted average, product tier or firm price.
Match the reference scope first
- Confirm Installation before applying this reference to your quantity. New-construction windows and new openings are outside the replacement-window reference. Field review still requires scope confirmation.
- Confirm Frame condition before applying this reference to your quantity. Concealed damage and flashing/leak investigation are not covered by the basic replacement reference.
The figures above remain the source reference. They do not price these selections or a complete installed project.
A planning reference for this service only. Selections, local labor, access, quantities and existing conditions need Coastal’s review. Do not add overlapping whole-project and component ranges.

Illustrative planning allowance for the stated scope, not a promised start or completion date. On-site time starts after approvals and materials are ready; procurement, inspection waits, curing and discoveries can extend the calendar.
Product manufacturing lead time · Opening count and access · Rot, masonry or structural opening changes
PERMIT PLANNING
Check the scope and jurisdiction
Permit needs depend on the work and property address. OKC and Edmond review structural alterations; Moore requires permits for most remodels. Confirm finish-only exceptions and any separate trade permits.
- Changes to walls, structure or building use
- Electrical, plumbing or HVAC changes
- Work within a floodplain or historic district
ENGINEERING & DESIGN
Engineering is not usually needed
Engineering is not usually part of this finish-only scope. Stop for review if hidden damage, structural changes or unusual support loads are found.
- New structural work or damaged framing
- Unverified heavy-load support
Confirm requirements with the city or county responsible for the property before work begins. The address, exact scope and adopted code determine the final requirements.
