Power Washing at a property in Crystal Lake on Berry Street. 1800 sq ft. Completed by our Barrington team.
— Barrington crew
Crystal Lake properties that sit under mature tree cover tend to accumulate the kind of grime that plain water alone won't touch — mildew working into the surface, black streaks tracing the low spots, organic buildup that builds season after season until it becomes part of the texture. That's the condition we found when we arrived at this residential property: roughly 1,800 square feet of exterior surface and a brick paver patio that had clearly gone a few seasons without a serious cleaning.
We ran a soap application first, letting the detergent dwell long enough to break down the mildew and lift the black streaking before we brought the pressure to bear. Working across the full 1,800 square feet methodically, we kept the wand angle consistent on the pavers to avoid disturbing the joint sand while still pulling the embedded grime out of the surface. The brick responded well once the soap had done its work — the streaking that had settled into the low points of the paver pattern cleared out pass by pass. By the time we rolled up the hoses, the surface read the way it should: the actual color of the material, not the color of everything that had landed on it.
Crew on this job
Timothy
Timothy may be our youngest technician, but don’t let that fool you. He’s experienced, professional, courteous, and already knows his way around the job like a seasoned pro. He’s also a promising DJ, so there’s a good chance he can fix the problem and recommend a solid playlist while he’s at it. Everyone loves Timothy because he’s easy to talk to, always upbeat, and genuinely enjoys meeting people. He also has a strange love for Wisconsin, which we still haven’t fully figured out - but nobody’s perfect.

Common questions from Crystal Lake homeowners researching Power Washing.
For a large patio around 1,800 sq ft with heavy mildew and black streak buildup, this job came in at $900. In the Crystal Lake area, power washing for a surface that size typically runs $600–$1,000 depending on how soiled the surface is and whether soap treatment is needed.
A heavily soiled 1,800 sq ft patio like this one — with mildew, black streaks, and a soap pre-treatment step — generally takes a crew a half day to do properly. Rushing the dwell time on a dirty surface means the grime comes right back, so we don't cut corners on soak time.
On a job like this one, we covered the full 1,800 sq ft of patio surface, applied soap to break down the mildew and black streaking, and did a thorough pressure rinse to flush all residue away. The goal is a clean, even finish across the entire surface — not just the easy spots.
When done at the right pressure with the correct nozzle, power washing is safe for concrete and most paver surfaces — and it's often the only way to fully remove embedded mildew and black algae streaks like we dealt with on this job. We adjust pressure and use soap pre-treatment so the surface gets clean without pitting or etching. For a quote, call our Barrington team at (847) 715-9493.
