Exterior Cleaning in Clarendon, Virginia
That's why Lawn Theory doesn't sell a house wash or a gutter cleaning as separate errands in Clarendon. The Exterior Cleaning package is engineered as one coordinated job: soft-wash chemistry lifts mold, algae, and pollutants off siding, brick, and trim without the pressure that damages older 1920s-era wood and stucco; gutters get flushed and inspected so runoff stops re-staining the very walls just cleaned; and hardscape \— walkways, patios, driveway aprons, stoops common to Clarendon's.
The Short Answer
Most exterior cleaning in Clarendon runs about $0.10–$0.50 per square foot — a typical house washing lands around $250–$700, and bundling surfaces on one visit brings the per-surface price down. Every surface gets the right method: soft wash for siding and roofs, true pressure for concrete and stone. Every project starts with a free walkthrough and ends with a written, line-item quote in 24–48 hours.

What Neighbors Say
Trusted on Homes Like Yours
“We hired Lawn Theory for pressure washing and landscaping. It is like we have a brand new home. Five stars!”
“They explained why they'd soft-wash our deck instead of blasting it with a wand, and I appreciated that. Came out clean without a single splintered board.”
“Written quote same day, on time for the appointment, and our HOA letter about the driveway staining is officially resolved. Would use again for our patio next.”
Clarendon, Answered
Exterior Cleaning in Clarendon — Common Questions
Does Lawn Theory really clean the house, gutters, and hardscape all in one visit in Clarendon?
Yes. The Exterior Cleaning package is built as a single coordinated service call: soft-wash of siding and brick, full gutter clearing, and pressure cleaning of walkways, patios, and stoops, sequenced so runoff from one step doesn't undermine another. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Is soft-washing safe for Clarendon's older 1920s bungalows and stucco homes?
Soft-washing is specifically chosen for older or delicate materials. Instead of high pressure, we use a lower-pressure application with cleaning solution that lifts algae, mold, and grime without stripping paint or damaging aged stucco, wood trim, or brick mortar joints. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
How often should exterior cleaning be done on a Clarendon property?
Most homes in Clarendon's tree-lined blocks do well on a twice-yearly cadence, spring and fall, timed around pollen season and leaf drop, which are the two biggest drivers of gutter overflow and surface staining in this neighborhood. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Will pressure washing affect my neighbors in a rowhouse or condo setting?
That's exactly why sequencing matters. In Clarendon's denser blocks near Wilson Boulevard and Courthouse, we control runoff and overspray carefully so shared walls, patios, and neighboring units aren't affected. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
What hardscape surfaces are included in the package?
Walkways, entry stoops, patios, and driveway aprons are all cleaned as part of the package, matched to whatever concrete, paver, or brick surfaces the property has. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Why combine gutters with the house wash instead of scheduling them separately?
Clogged gutters overflow onto siding and cause the streaking and algae growth that undo a house wash within weeks. Clearing them in the same visit protects the results of the soft-wash instead of letting runoff undo the work. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
What does exterior cleaning include?
Anything outside the walls of the house: house washing, roof cleaning, driveways and walkways, decks and fences, patios, gutters, and windows — each cleaned with the method its surface requires, and bundled visits are priced lower per surface. Serving Clarendon and all of Arlington. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
