One large window replaced on a 1950s ranch house
Example project

- Home
- 1950s single-story ranch house in Novato with horizontal wood siding, under oak trees
- Original request
- Replace the large window on the long wall
- Testing
- Older painted frame and sill, tested first; lead paint found
- New window
- One large unit set in the existing opening
- Ground
- Plastic laid along the base of the wall below the windows
- Estimated cost
- $1,400
Scope of work
Plastic inside the room and along the base of the wall outside, the old sashes, stops and casings misted and taken out whole, one new large unit set in the existing opening, the inside trim refitted, HEPA cleanup and a wet-cloth check of the sill and floor. The siding is not part of this price.
Project overview
In this example, the owners of a 1950s ranch house in Novato replace the large window on the long wall, which no longer seals. Its frame and sill carry older paint, so they are tested first, and the test shows lead paint.
Replacing windows in a house built before 1978 is always covered by the federal lead-safe rule, so the room is sealed and plastic is laid along the base of the wall outside, under the oaks, while the old window comes out. The siding is left alone.
The goal
The goal is a large window that seals, with no lead dust left in the room or on the ground below.
Process
- Testing Frames and sills tested and the opening measured for the large unit.
- Setup Plastic laid inside, and along the base of the wall outside.
- Windows Old sashes and casings out whole, new unit set, trim refitted.
- Check HEPA cleanup and a wet-cloth check of the sill and floor.
Planning right
- A large unit costs more to set than a small one, which is why this price sits near the top of the line.
- Leaves and acorns blow the plastic about, so it is weighed down and checked each morning.
- The other windows on the long wall may carry the same old paint. Test them before they are touched.
- Old sashes leave the house wrapped, not dropped on the ground.
