Covina Interior + Exterior Painting | NPLD 2026
Covina has more post-war ranch homes inside the 91722, 91723, and 91724 zips than most San Gabriel Valley cities. These are 1,400 to 2,200 square-foot single-story houses on flat lots, built between 1948 and 1962, with original stucco, original wood eaves, and almost always at least one coat of failing oil-based paint underneath the latex someone rolled over it in 1998. Painting in Covina is not about color. It is about prep. NP Line Design has drawn LA homes since 2016 and held the CSLB GC license since 2023. We pull Covina Building Department permits when prep crosses the lead-safe threshold, we strip what needs stripping, and we paint inside and out under one general contractor.
Covina interior and exterior paint costs in 2026
Full interior and exterior painting in Covina lands $14K to $48K in 2026. A 1,600 square-foot post-war ranch interior repaint with two-tone walls, ceilings, full trim, and standard prep lands $9K to $14K. The matching exterior on original stucco with wood fascia, soffits, garage, and front entry door lands $9K to $16K including pressure wash, scrape, prime, and two finish coats. Step up to a 2,400 square-foot expanded ranch with detached garage, deeper trim package, accent siding, and lead-safe prep on the 1953 original stucco and you land $32K to $48K. EPA RRP lead-safe certified prep on pre-1978 surfaces adds $3K to $9K depending on how much paint actually fails the test.Why post-war Covina ranches need real prep
Almost every Covina ranch we paint has the same problem. The original 1953 exterior was oil-based. Someone in the late 1990s rolled latex over the oil without proper bonding primer. By 2015 the latex was peeling in sheets along the south and west elevations where the sun cooks. The 2025 quick-flip paint job spray-painted over the peel without scraping. We do not do that. We pressure-wash, scrape to sound substrate, spot-prime bare wood with an oil or shellac bonding primer, spot-prime the failed stucco with an elastomeric undercoat, and only then move to finish coats. That is why a real Covina exterior takes nine to fourteen days, not three. It is also why our paint lasts ten years and the cheap one lasts eighteen months.The 210 corridor noise and dust problem
Homes in north Covina close to the 210 freeway carry a continuous coat of brake dust, tire rubber, and diesel particulate that no homeowner ever sees until we pressure-wash. The film bonds to stucco and to wood, and rolling paint over it fails. We test-wash a panel before bidding. If the rinse runs gray we add a TSP-and-detergent wash step to the prep budget. It adds $800 to $1,800 to a typical Covina exterior. It is not optional on a 210-corridor lot.Interior color on small-room post-war floor plans
Covina ranch bedrooms are small. Most are 10 by 11 or 11 by 12. Painting them in the saturated jewel-tones that are trending on Instagram makes them feel like a closet. We will paint a saturated color if the homeowner is sure, but we will swatch first, we will paint a 4 by 4 test panel on the wall opposite the window, and we will look at it at morning, midday, and dusk before we commit. Most Covina interiors land best in warm off-whites, soft greiges, and one or two accent walls in deeper tones. The post-war floor plan is unforgiving of over-saturation. We will not let you make that mistake.Lead-safe prep is the law, not a marketing line
Any pre-1978 Covina home with paint disturbance over six square feet interior or 20 square feet exterior triggers EPA Renovation Repair and Painting rules. We hold the RRP firm certification. Our prep crew leads hold the RRP renovator certification. We HEPA-vacuum, we plastic-contain, we wet-scrape, and we document. We do not sand-dust your kids' bedroom with lead paint and call it a paint job. If a contractor bids a 91722 exterior at $7K, they are skipping the lead-safe prep. Walk away.How we sequence the job so you actually live in the house
A real repaint disrupts daily life if it is not sequenced right. We start interior work in the rooms the family uses least (formal living, guest bedroom, dining room), move to the secondary bathrooms, then the kitchen on a Saturday-Sunday push, then the bedrooms last working primary to secondary. Exterior runs concurrent on a separate crew, pressure-washing first thing on day one and prepping while the interior pulls ahead. We cover the entire exterior perimeter in 6-mil plastic at four feet of overlap so paint overspray never reaches the landscape, the pool, the patio furniture, or the neighbor's car. We sweep up at the end of every day, we vacuum the interior at the end of every day, and we leave the house cleaner than we found it. The family sleeps in the house every night. That is the standard.Interior + Exterior Painting Questions Homeowners Ask About Interior + Exterior Painting in Covina
Do I need a permit to paint my Covina house?
Not for paint itself. EPA RRP rules apply to any pre-1978 surface and require certified containment. We hold the certification.
How long does a full Covina ranch repaint take?
Plan on 10 to 20 working days. Interior runs four to seven days. Exterior runs eight to fourteen days including proper prep and weather buffer.
Will the new paint match what is left on the back of the house?
Only if we paint the back. We strongly recommend full 360-degree exteriors on Covina ranches because the original stucco fades unevenly and patch-painting is visible from the alley.
What paint do you use on Covina exteriors?
Sherwin Williams Duration or Emerald Rain Refresh on stucco. Benjamin Moore Aura on trim. Both carry manufacturer warranties of 15 years plus.
Can you paint over my failed 1990s latex?
Only after we strip the loose paint, sand the edges feathered, and prime with a bonding primer designed for the failed substrate. We do not paint over peeling paint.
Is your crew certified for lead-safe work?
Yes. NPLD holds the EPA RRP firm certification and our prep leads hold individual RRP renovator certifications. We document every job.
How do you handle the dust from 210 freeway brake particulate?
TSP-and-detergent wash before the final pressure rinse. We test-wash a panel during the bid walk and price the wash into the contract.
Do you guarantee the work?
Yes. Five-year written workmanship warranty on exterior paint installed over properly-prepared substrate. Manufacturer warranty stacks on top.
