Exterior Cleaning in Merrifield, Virginia
Lawn Theory runs exterior cleaning the way Sufian ran logistics during Operation Iraqi Freedom: one plan, one pass, zero wasted motion. We soft-wash the entire building envelope at a pressure low enough to protect Hardie board, brick, and older vinyl, then flush the gutter system so it sheds water instead of backing it onto fascia, then finish on patios, walkways, and driveways so the whole property reads as one clean, cared-for asset instead of a.
The Short Answer
Most exterior cleaning in Merrifield 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.

Exterior Cleaning in Merrifield — Common Questions
What's included in Lawn Theory's exterior cleaning package for Merrifield homes?
A complete package covers three fronts in one scheduled visit: a low-pressure soft-wash of siding, brick, or stucco to remove algae and airborne film, a full gutter flush and downspout check so water sheds correctly, and pressure washing of hardscape surfaces like patios, walkways, and driveways. We coordinate the sequence so runoff from the house wash doesn't undo work already done on the ground.
Why do Merrifield homes need this more than one-off pressure washing?
Merrifield sits between I-66 traffic film and the ongoing construction corridor near Dunn Loring Metro and the Mosaic District, which deposits fine grit on siding faster than in quieter suburbs. Treating siding, gutters, and hardscape as separate jobs leaves gaps, clean siding above a clogged gutter still stains the fascia, and a washed house next to a stained driveway still looks neglected.
How often should exterior cleaning be scheduled in Merrifield?
It depends on tree cover and sun exposure. Shaded lots in wooded, mature neighborhoods like Dunn Loring Woods typically need a service twice a year to stay ahead of algae, while sunnier, newer sections near the Mosaic District redevelopment can often hold on an annual cadence. We set the schedule during the first visit based on what we see on your property.
Is soft-washing safe for older Merrifield homes with original siding or brick?
Yes. Soft-washing uses low pressure and the correct cleaning solution for the surface, which is specifically why we use it on the mix of 1950s and 60s ranch, split-level, and brick Colonial exteriors common throughout Merrifield and Dunn Loring. High-pressure washing can strip paint or drive water behind siding on older homes; our approach is built to avoid that.
Do you clean gutters as part of every exterior cleaning visit, or is it separate?
Gutters are built into the standard exterior cleaning package, not an upsell. A soft-washed house with a gutter still packed with debris just moves the water problem down the fascia, so we flush and check downspouts every time we're on-site for a full exterior service.
Will exterior cleaning help with staining on my driveway or patio near Mosaic District construction?
Yes, hardscape washing is part of the same visit. Fine construction grit and diesel residue from the redevelopment corridor settle into concrete and paver joints and tend to look worse over time if left untreated. We pressure wash driveways, walkways, and patios in the same service call so the whole property is addressed at once.
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 Merrifield and all of Fairfax County.
