SIDING, TRIM & WEATHERPROOFING

Window flashing and weather sealing

Investigate water entry around a window and define the flashing repair needed at the opening. Visible caulk is considered alongside sill, jamb, head and wall drainage details so concealed failures are not disguised by a surface bead.

START WITH THE DETAILS

What goes into
the work.

Measure each exterior wall and subtract openings. Record trim, gutters and sealant joints by length, plus height and access.

Typical scope to confirm

  • Inspect visible joints, staining and drainage paths
  • Define any selective cladding or trim removal
  • Integrate the agreed flashing repair with the existing water-resistive barrier
  • Restore specified trim and seals

Make it specific to your project.

KNOW WHAT COMES NEXT

From first idea to finished work.

    Review how the opening connects to the wall’s water-management layers.

  2. Prepare and approve

    Confirm materials, access and concealed-condition allowances.

  3. Complete the work

    Install or repair the selected system with coordinated flashing and seals.

  4. Review and close out

    Review joints, drainage and finish continuity; explain maintenance.

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.
