Family-Operated Local Commercial Painters Since 1976

Exterior Commercial Painting Company in San Luis Obispo County and Surrounding Areas

A commercial exterior is the first thing customers, tenants, and prospects see. Faded paint, mildew, and peeling trim signal neglect even when the business inside is doing well. A well-maintained exterior keeps tenants renewing at higher rates, holds asking prices up at sale or refinance, and makes prospects walk through the door instead of past it. A neglected one costs you in every one of those places before you ever notice it on the income statement.

Trombley Painting Company handles exterior commercial painting across San Luis Obispo County for retail storefronts, office buildings, multi-family complexes, hotels and motels, restaurants, churches, gyms, schools, public buildings, and HOA-governed communities.

We do the same prep-and-two-coats process as residential, scaled up for commercial scope. We also use bucket trucks and lifts where needed. Multi-week scheduling for larger projects. Each project is backed by a 3-year workmanship warranty.

Full Exterior Commercial Painting

A commercial exterior project from Trombley Painting Company starts with a property walkthrough that includes the property manager or business owner. We document existing conditions, identify scope (siding, trim, doors, soffits, fascia, painted concrete, painted brick, signage areas), and confirm timing constraints around tenant or operational use.

Larger projects use bucket trucks and lifts. Multi-building projects are scheduled across weeks with daily progress updates to the property manager. We also use Sherwin-Williams Pro commercial-grade exterior products on every job.

  • Schools, Hospitals & Facilities

  • Religious Buildings

  • Gyms & Fitness Centers

  • Restaurants

Commercial siding includes hardboard, metal panel, EIFS, and stucco systems on retail strips, office buildings, multi-family complexes, and warehouses. Each substrate needs different prep and different products. Hardboard gets exterior acrylic.

Metal panel gets DTM (direct-to-metal) acrylic with anti-corrosion primer on bare or rusted areas. EIFS gets manufacturer-approved coatings to maintain warranty. Stucco gets Loxon elastomeric for crack bridging. We identify substrates during the property walkthrough and quote each separately.

Commercial gutters and downspouts get painted for two reasons: corrosion protection on bare or rusted metal, and color matching to trim or signage areas. We sand any rust, prime bare metal with anti-corrosion primer, and apply two coats of exterior enamel formulated for metal.

Aluminum and steel gutters get the same prep. Multi-story buildings use bucket trucks or lifts for safe access. Often included as a line item on a full exterior commercial project.

Commercial doors include glass-and-metal storefront entries, solid steel back-of-house doors, hollow metal exit doors, and wood interior or exterior doors. Each gets a different system. Steel doors get DTM acrylic with anti-corrosion treatment on any rust. Hollow metal exit doors get the same.

Storefront entries get specialty coatings designed for high-touch surfaces with frequent cleaning. Interior wood doors get Sherwin-Williams Pro Industrial water-based alkyd for a hard, washable finish.

Commercial outdoor wood includes apartment complex balconies and railings, hotel pool deck areas, restaurant patio structures, and HOA common-area fencing. Same prep-and-two-coats process as residential outdoor wood, scaled for commercial volume. Heavy-traffic balcony decks get foot-traffic-rated paint.

Railings and gate hardware get exterior enamel rated for high-touch surfaces. Wood fencing gets solid-color exterior paint for uniform color across long runs. Coastal commercial properties (Morro Bay, Cambria) get marine-grade products formulated for salt air.

Exterior electrical boxes, conduit runs, and meter housings can be painted to match the building exterior for a clean uniform look. Power is shut off at the relevant disconnect during the prep and paint application, then restored after the finish has cured.

We coordinate with the property’s facility maintenance team on shutdown timing for occupied buildings. DTM acrylic paint specifically because it bonds to the painted metal substrate without separate primer.

Commercial exterior projects often include minor carpentry repair as part of prep: replacing rotted soffit and fascia boards, securing loose siding, repairing damaged trim, and patching small siding damage. We handle minor repairs in-house.

Significant carpentry (full siding sections, structural wood replacement, large soffit repairs) is coordinated through a trusted local subcontractor as part of the project so you have a single point of contact for the whole job.

Quality Products and Commercial Painting Professionals

Trombley Painting Company uses Sherwin-Williams Pro commercial-grade exterior lines on every project. Stucco gets Loxon elastomeric. Wood and hardboard siding gets Duration or Resilience exterior acrylic. Bare metal gets Pro Industrial DTM acrylic with anti-corrosion primer.

EIFS systems get manufacturer-approved coatings. The exact products are specified on every written quote so the property manager or owner knows exactly what is going on the building.

Exterior commercial painting FAQs

For commercial exterior work, three things matter most: insurance documentation, scheduling discipline, and warranty length. Trombley Painting Company carries full commercial liability and workers’ comp with certificates available on request, schedules around tenant and operational constraints, and backs every project with a 3-year warranty.

A single storefront or small commercial building runs $5,000 to $15,000. A mid-size commercial building runs $15,000 to $50,000. Large multi-building complexes start at $50,000 and scale from there based on scope. Every quote is fixed.

For most commercial properties, yes. Faded or peeling exteriors signal neglect and reduce perceived property value. Tenants notice. Customers notice. Buyers and lenders notice. A fresh exterior on a commercial property typically pays back in tenant retention, asking-price increases, and faster lease-up on vacancies.

Late spring through early fall (May through October) is ideal for most exterior projects. For hospitality properties (hotels, restaurants), shoulder seasons (April-May or September-October) work best. For schools, summer break is the standard. For retail, after the holiday season is common.

Yes. Full commercial general liability, full workers’ compensation, and full California painting contractor license. Certificates of insurance are issued in advance of any commercial project at no charge. Additional insured endorsements are available if your property requires them.

A single storefront takes one to two weeks. A mid-size commercial building takes two to four weeks. Large multi-building complexes take multiple months, phased across buildings. The exact timeline is on every written quote and updated weekly during the project.
