Exterior Painting.

A properly applied exterior paint system — correct prep, oil-based spot prime on bare wood, full acrylic prime coat, two 100% acrylic finish coats — should last seven to ten years in Montgomery County's humid continental climate before requiring more than minor touch-up. Systems that fail in two to four years almost always have a preparation or primer failure: either the old paint was not fully removed before new material went on, the bare wood was spot-primed with latex instead of oil-based primer, or finish coats were applied over inadequately primed substrate. The climate is demanding but manageable with the correct product system.

Yes, though masonry painting requires a different approach than wood siding. Brick and masonry must be fully cured, dry, and free of efflorescence before paint is applied. Efflorescence — the white mineral deposits that leach through brick from mortar moisture — cannot simply be painted over; it must be removed with a masonry cleaner and the moisture source addressed before coating. The primer for masonry is an alkali-resistant masonry primer, which neutralizes the high-pH surface that causes standard acrylic primers to fail or bubble. Once primed, masonry is topcoated with 100% acrylic paint in a product formulated for masonry — not standard siding paint. Jose evaluates masonry condition during the estimate walk and identifies any repointing or waterproofing work that should precede painting.

Late spring and early fall are the best windows — typically mid-May through mid-June and September through mid-October. These periods provide moderate temperatures (55°F to 80°F), lower humidity, and lower chance of precipitation than summer peak. Summer painting is workable but requires scheduling around high humidity days and avoiding direct sunlight on heated surfaces, where paint can blister. Winter exterior painting is generally not possible in Montgomery County — temperatures regularly drop below the 50°F minimum for latex acrylic application from November through March. If a late-season job is needed, oil-based primer extends the application temperature window to about 40°F, but the full system still requires latex topcoat at appropriate temperatures.

Yes. we use a spectrophotometer-matched paint order for color matching on partial repaints — the existing color is scanned against manufacturer paint deck and matched to the closest formula. For older homes where the paint has faded significantly from the original color, matching to the faded tone rather than the original formula produces a more seamless result. Full-exterior repaints bypass the matching question entirely and allow a new color selection. For homes in HOA-governed communities in Blue Bell or Skippack, Jose reviews the HOA-approved color palette before specifying any exterior color.

Pressure washing is part of the surface prep sequence, but it must be done at the right point in the process and with the appropriate pressure settings for the surface. the crew pressure-washes after initial scraping to remove loose paint, chalk, and dirt, then allows the surface to dry thoroughly before any primer or paint is applied. 'Thoroughly dry' for wood siding means a minimum of 48 hours of dry weather — wood that is surface-dry but still holding moisture in the fiber will cause latex primer to bubble as the moisture escapes. Pressure settings are calibrated to the surface: 1,200–1,500 PSI for wood siding, lower for softer woods and older homes with thin remaining paint build, to avoid raising grain or driving water behind trim boards.
