Heavy trim packages and deep eaves
Custom homes here often have several times the fascia, casing, and decorative woodwork of a tract home, and each profile needs caulk, primer, and careful cut-in. When you compare estimates, ask how linear footage of trim is counted — it is where scope differences between bids usually hide.
Canyon-side sun and Santa Ana winds
Homes along Weir Canyon and the eastern hills take direct sun plus seasonal Santa Ana wind, which opens caulk joints and dries out exposed wood faster than sheltered streets. Re-caulking and spot-priming before any finish coat is what keeps a repaint looking right past the first wind season.
