Commercial Exterior Painting: A Northern Virginia Guide for Property Managers

Most commercial building exteriors need repainting every 5 to 10 years, sooner on sun-beaten walls, wood trim and metal, and later on well-coated masonry. In Northern Virginia, the best time to do the work is spring through fall, when temperatures stay above the paint's minimum day and night. The coating has to match the surface, and the prep, mostly washing, repairs and caulking, decides how long the job lasts.

An exterior repaint is one of the larger maintenance projects a property manager or board takes on, and one of the most visible. This guide covers how often to plan for it, which coatings suit which surfaces, the best season to schedule it, what good prep looks like, how crews work safely at height and what drives the price.

How often should a commercial building exterior be repainted?

Plan on roughly 5 to 10 years for most buildings, and inspect every year in between. Lenders and housing agencies that budget for building repairs use similar numbers. Fannie Mae's multifamily useful life tables list exterior painting at 5 to 10 years, and HUD's capital needs assessment table assigns exterior paints and stains an estimated useful life of 8 years.

Those are planning averages. Where your building lands in that range depends on:

• Surface. Wood trim and metal usually need attention first. Coated masonry and stucco tend to last longer.
• Exposure. South- and west-facing walls take the most sun and fade and chalk first.
• The last job. A repaint over good prep with a quality coating lasts far longer than a quick coat over dirt and failed caulk.

What are the signs a commercial exterior needs paint?

Walk the building once a year, ideally in spring, and look for:

• Chalking. Rub a hand across the wall. A heavy powder on your palm means the coating is breaking down.
• Peeling, flaking or blistering, especially near gutters, sills and grade, where water collects.
• Fading or uneven color between sunny and shaded sides of the building.
• Cracked or missing caulk around windows, doors, joints and penetrations.
• Rust on railings, doors, frames, canopies and metal panels.
• White, powdery deposits on masonry, a sign of water moving through the wall.
• Soft or rotted wood on trim, fascia and soffits.

Catching these early usually means a repaint with spot repairs. Waiting usually means carpentry, masonry repairs and a bigger bill. If paint keeps failing in the same spot, our post on why exterior paint keeps peeling in the same spot explains the usual moisture causes.

What type of paint is best for commercial buildings?

There is no single best exterior paint for a commercial building. The right coating depends on what it is going on:

• Concrete, block and stucco: a masonry acrylic or an elastomeric coating over the right primer or conditioner. Elastomerics go on thick and stay flexible. Sherwin-Williams describes its ConFlex XL elastomeric as one that bridges hairline cracks and helps keep water out, even in wind-driven rain, while staying permeable so moisture vapor can escape.
• Brick: first decide whether to paint it at all, because unpainted brick needs little upkeep and painted brick needs repainting. Our post on painting brick and concrete board siding covers the trade-offs.
• Metal doors, railings, canopies and panels: remove loose rust, then use a rust-inhibiting primer and a direct-to-metal or industrial enamel topcoat.
• Wood trim, fascia and siding: a high-quality 100% acrylic exterior paint over primed, sound wood. Avoid thick elastomeric coatings on wood. Wood has to release moisture, and a film that traps it can lead to blistering and rot.
• Fiber cement and vinyl siding: a quality acrylic, in a color that is safe for the siding. Very dark colors can make vinyl overheat and warp.

A good contractor names the primer and topcoat for each surface in the bid, so you know exactly what you are paying for.

What type of exterior paint lasts the longest?

A quality acrylic or elastomeric system, applied at the right thickness over a clean, sound, properly primed surface, outlasts any premium paint applied over poor prep. In practice, durability comes from three things working together:

• Prep. Paint only lasts as long as the surface it sticks to.
• The right product for the surface, as described above.
• Enough paint. Two full coats at the manufacturer's spread rate, not one thin coat stretched to cover more wall.

Lighter colors also tend to show less fading than deep, saturated colors, which matters on large sunny walls.

When is the best time of year for commercial exterior painting in Northern Virginia?

Late spring and early fall are the sweet spots: mild temperatures, lower humidity than midsummer and less rain than early spring. Summer works too, with crews starting early and moving with the shade on hot days. Winter is the hard season, though a stretch of mild weather can still be usable for some products.

What decides it is the product's minimum temperature, and that varies by coating:

• Many modern exterior acrylics can be applied down to 35°F. Sherwin-Williams lists lines such as Duration, Resilience, SuperPaint and A-100 Exterior as rated for application down to 35°F.
• Elastomeric masonry coatings often need warmer weather. Sherwin-Williams' elastomeric product guide lists an application temperature of 50° to 100°F for its ConFlex line.
• Large expanses of metal siding can also call for 50°F or warmer, even with low-temperature paints, according to the manufacturer's data sheets.

So a stucco or concrete building that needs an elastomeric coating has a shorter season than a wood-trimmed building getting acrylic. Plan masonry work for April through October, and book early, because good commercial crews fill their spring and fall calendars months ahead. Homeowners will find the residential version of this advice in our post on the best time to paint a home exterior.

When should you not paint an exterior?

Most exterior paint failures that show up in the first year trace back to the weather on painting day. Do not paint:

• Below the product's minimum temperature, or when it will drop below that minimum overnight.
• On a damp surface, after rain, heavy dew or a pressure wash that has not dried.
• When dew is about to form. Sherwin-Williams notes that the temperature should ideally stay in range and above the dew point for at least 48 hours after application. In fall, that means stopping early enough in the afternoon for the paint to set before evening dew.
• When rain is forecast before the paint has had time to dry.
• In direct midday sun on very hot days, when the surface is too hot and the paint dries before it can level and bond.

What prep goes into a commercial exterior repaint?

On most exteriors, prep is more of the labor than painting. A typical sequence:

• Wash. Remove dirt, chalk, mildew and pollen so the new coating bonds to the surface, not to the grime. The Painting Contractors Association publishes a standard, PCA P22, for cleaning surfaces with pressurized water. Pressure, nozzle and distance matter, especially on soft wood and older masonry. Our exterior washing service is often scheduled as the first phase of a repaint.
• Let it dry. Masonry and wood need time after washing before they can be painted.
• Scrape and sand loose and flaking paint back to a sound edge.
• Repair. Replace rotted wood, patch masonry and stucco, and treat rust on metal.
• Caulk and seal joints, windows, doors and penetrations with an exterior-grade sealant.
• Spot prime bare wood, repaired areas, rusted metal and new masonry patches.
• Protect windows, doors, landscaping, walkways and parked cars.

A bid that does not describe the prep in detail is the one most likely to cut it.

How do painters work safely on taller buildings?

Access is one of the biggest cost and safety factors on a commercial exterior. Depending on height and site, crews use extension ladders, aerial lifts, scaffolding or suspended platforms. OSHA requires fall protection for construction workers on surfaces 6 feet or more above a lower level, so ask any contractor how they will reach each elevation and who on the crew is trained to set up and use that equipment.

On an occupied building, the work zone also has to be managed for everyone else. Expect cones or barriers under overhead work, protected entrances that stay open, coordination with the building on parking and deliveries, and advance notice to tenants or residents. Our guide to painting an occupied commercial building covers the notice and scheduling side.

How much does commercial exterior painting cost?

Commercial exterior painting typically runs about $2 to $6 per square foot of paintable surface, based on the published ranges in our commercial painting cost guide for Northern Virginia. That works out to roughly $10,000 to $30,000 for about 5,000 square feet of surface.

The biggest swings come from:

• Height and access, such as lifts, scaffolding and work over entrances or sidewalks.
• Condition and prep, including how much scraping, carpentry, masonry repair and caulking is needed.
• The coating system. Elastomerics and industrial metal coatings cost more per gallon and cover less area than standard acrylic.
• Scheduling around occupants, such as phasing, entrance protection and limits on working hours.

How do you choose exterior colors for a commercial building?

Start with the rules before the swatches. Many condo and HOA communities have architectural guidelines, many commercial leases and brand standards dictate colors, and some localities have design review for certain districts. Confirm what applies before anyone falls in love with a color.

From there, a few practical points:

• Look at large samples on the building itself, on more than one side and at different times of day. Colors read lighter outdoors than on a chip.
• Consider maintenance. Very dark and very saturated colors show fading sooner on sunny walls.
• Coordinate with what is not being painted, such as the roof, brick, stone, windows and signage.
• Keep a color record of every product, color and sheen used, so touch-ups and the next repaint match.

Final Takeaway

Plan a commercial exterior repaint every 5 to 10 years and inspect every year in between. Match the coating to each surface, schedule masonry and elastomeric work for the warmer months, insist on detailed prep in the bid, and make sure the contractor has a safe plan for working at height around the people who use the building.
