Power washing questions, answered

Residential window cleaning is priced per pane, and most homes in this area land between $150 and $400 for the exterior. Inside and out together typically runs $250 to $600 depending on the window count.

Screens, sills and tracks are included rather than billed separately. Second and third story glass, casements and anything needing ladder work costs a little more, and hard water spotting from sprinkler overspray is quoted after we see it, since years of buildup sometimes needs more than one treatment.

Most decks in this area run $200 to $450. A small single-level deck is $175 to $250, and larger multi-level decks with railings, spindles and stairs reach $400 to $600. Fences are quoted by linear foot.

Wood takes longer than composite, because it has to be cleaned at low pressure and given time to work rather than being pushed. If you are planning to stain or seal afterward, the cleaning is what decides whether the finish takes evenly or blotches, so it is worth doing properly.

Cleaning a paver patio and re-sanding the joints together generally runs $400 to $900, depending on square footage and how far gone the joints are. Cleaning on its own costs less, but we rarely recommend it alone, because an empty joint is a worse problem than a dirty one.

Polymeric sand is the larger part of the material cost. It also has to go down on a fully dry surface, so a combined job is usually two visits: clean one day, sand the next.

Pool surrounds and steps take longer per square foot than an open patio, since the coping and nosings need the most care.

A standard two-car driveway usually runs $150 to $225. Add walkways, front steps and a patio and the visit moves into the $250 to $400 range.

Heavy oil staining, rust from a downspout or fertilizer, and old tire marks add $50 to $100, because those need pre-treatment before any pressure comes out. Pressure alone does not lift them.

Most people book concrete alongside a house wash, which costs less than scheduling two separate visits.

Roof soft washing in northern New Jersey generally runs $300 to $700. A single-story roof is usually $300 to $450 and a two-story $400 to $600, with steep pitches, multiple dormers and complicated rooflines at the upper end.

It costs more than a house wash because the work is slower, the access is harder, and everything below the drip line has to be protected and pre-wet before any solution goes on the shingles.

It is still a small fraction of a roof replacement, which is where unchecked moss and lichen eventually lead. Free estimates: 973-897-1757.

A typical house wash in this area runs $250 to $500. A 2,000 square foot two-story home usually falls between $350 and $475, and a single-story ranch comes in below that.

The number depends on square footage, how many stories, how much algae has built up on the shaded elevations, and how tight the access is around the house. Cedar, stucco and older painted wood take longer than vinyl and are priced accordingly.

We quote most house washes from photos of each side of the home, so you can get a real number without scheduling a walkthrough first.

Gutter cleaning in Morris and Passaic County generally runs $150 to $400 per visit. A single-story ranch is usually $150 to $250, a two-story colonial $200 to $400, and larger or three-story homes $300 to $500.

Two things push it higher: heavy debris after a bad fall, and a steep or complicated roofline that needs extra ladder work. Underground leaders that need tracing add a little as well.

Homes on heavily wooded lots in Kinnelon, Towaco and Wanaque need clearing twice a year, and recurring service is priced better than a one-off call placed after the gutters have already backed up and the fascia is wet.

Most residential power washing jobs in Morris and Passaic County land between $250 and $500. A 2,000 square foot two-story house wash typically runs $350 to $475, a standard two-car driveway $150 to $225, and gutter cleaning $150 to $400 depending on the number of stories. Roof soft washing is the outlier at $300 to $700, because the work is slower and the access is harder.

What moves the number is square footage, how many stories, how far the algae has gotten on the shaded sides, and how easy it is to get equipment around the property. Booking two or three services on one visit costs less than scheduling them separately.

Estimates are free, and you get the number before any work starts. Call or text 973-897-1757.

Usually, yes. Email us photos showing each side of your home and we can estimate most jobs without a visit. It saves you scheduling a walkthrough, and if anything looks unclear in the pictures we'll tell you rather than guess.

Call or text Nick at 973-897-1757 and he'll set up a free estimate. Most jobs can be quoted from photos of each side of the house. For bigger properties he'll come walk it with you and talk through what you're actually trying to fix. Either way you get a number before any work starts, not after.

Not with a pressure washer. Moss and lichen grip asphalt shingles hard enough that blasting them off takes the protective granules with them, which shortens the life of the roof and voids most shingle warranties outright. Scraping and stiff brushing do the same damage, just more slowly.

The method every major shingle manufacturer endorses is soft washing: low pressure, a shingle-safe cleaning solution, and time. The growth dies at the root, releases its grip, and weathers away over the following few weeks rather than coming off in one visit.

Trimming back the limbs that overhang the affected pitch is the other half of the fix, since moss returns fastest where the roof never fully dries.

Yes. A clean trough draining into a blocked downspout accomplishes nothing. We flush every downspout and clear underground leaders where we can reach them, then check that the whole run actually flows.

Yes, and that's most of the job. We clear the growth and the soil it rooted into out of the joints before the surface gets cleaned. Getting it out is straightforward. Keeping it out is what the re-sanding step is for.

Not the way we do it. Pavers are hard enough to take real pressure, but a narrow nozzle held too close will etch the face of the stone and blow the joint sand out in stripes. We use a surface cleaner at a controlled distance so the whole field comes out one even color.

We strongly recommend it. Cleaning clears the old sand, soil, and moss out of the joints, which is exactly what needed to happen — but it also leaves those joints empty. Empty joints mean pavers that shift and rock, and weed seed with somewhere to land. Cleaning without re-sanding gets you about six months of good looks and a worse problem than you started with.

Fences, gates, pergolas, and deck framing are all included. We get the rails, spindles, and posts, not just the deck boards, so the whole structure matches when we're done.

Yes. Composite doesn't weather the way wood does, but it still collects grime and organic growth, and it still needs the pressure kept down. We clean it the same careful way.

It can, which is why we don't do it that way. Too much pressure furs up the grain and leaves permanent wand marks in the boards. Cleaning wood takes patience rather than power, so we work at low pressure with the right solution and let the wood come back on its own terms.

We won't, and that's deliberate. Pressure is right for concrete, brick, and pavers, but it drives water behind siding and furs up wood grain. Those get soft washed or cleaned at low pressure instead. We never trade a clean surface for a damaged one.

We pre-treat oil spots, rust, and organic growth before we ever start washing, which is what actually lifts them. Deep, old stains don't always come out completely, and we'll tell you what to expect when we look at it rather than promising and hoping.

Not if it's done with a surface cleaner, which is what we use. Wand stripes happen when someone cleans a big flat slab with a narrow nozzle and misses the overlap. We clean evenly so the whole surface comes out one color.

Eventually something will, since the shade and moisture that caused it are still there. But soft washing kills the growth at the source rather than knocking it off the surface, so it stays clean far longer than a rinse would manage.

Never. High pressure blasts the protective granules off asphalt shingles, which shortens the life of the roof and voids most warranties. We soft wash instead: low pressure, shingle-safe detergents, and a gentle rinse.

Eaves, soffits, and trim are part of the wash, not just the flat walls. Those are the spots that hold cobwebs and grime, and skipping them is how a clean house still looks dirty from the driveway.

The pressure, and what it's aimed at. Hard surfaces like concrete, brick, and pavers can take real pressure, so we pressure wash those. Siding, roofs, and wood can't, so we soft wash those instead. We match the method to the material every time.

Not the way we do it. High pressure drives water behind siding and strips paint, so we don't use it on your house. We apply a cleaning solution at low pressure, let the detergent do the work, and rinse gently. The result is a house that looks maintained rather than a house that looks blasted.

We do, and you can book inside and out together or just the outside. Plenty of customers schedule several exterior cleanings a year and one interior. We'll need someone to let us in for the interior work.

Yes. We work at height year-round and have the equipment to get to multi-story and hard-to-reach glass safely. If there's a window in your house you've never cleaned because you couldn't get to it, that's usually the one we're here for.

Usually, yes. Sprinkler overspray dries on the glass and leaves mineral deposits behind, and that haze doesn't come off with a rag and a bottle of cleaner. We treat the deposits directly. Years of buildup sometimes takes more than one treatment, and we'll tell you that at the estimate rather than after.

Yes. Screens get cleaned, and the sills and tracks get wiped out. Those are the parts most companies skip, and they're the reason a window can look only half-clean after somebody has technically washed it.

Clean rain doesn't undo a soft wash, so most of the time it's fine. Roof treatments in particular keep working for weeks after we leave. If a storm kicks up and leaves the house looking worse than when we started, call us and we'll come look.

Yes. We carry liability insurance and can provide a certificate before we start if you'd like to see it. We're on roofs and ladders year-round, and being properly covered is part of doing that work responsibly.

Late spring and early fall are the two best windows in northern New Jersey. Spring, once the oak and maple pollen has finished dropping in late May, clears off a winter of road film and the algae that grew through the damp months. Fall, after the leaves are down, sets the house up for winter and pairs naturally with a gutter clearing.

Anything above about 40 degrees works, so we run from March into December most years. Mid-summer is fine as well, though on a hot day we work the shaded elevations first, since cleaning solution dries too quickly on a wall in direct sun to do its job.

Twice a year for most homes in Morris and Passaic County: once in late spring after the seed and blossom drop, and once in late fall once the leaves are down. On heavily wooded lots in Kinnelon, Towaco, or Wanaque, twice is the minimum rather than the target.

Most residential patios are a single day for the cleaning. If you're re-sanding, that has to go down on a fully dry surface, so it's usually the following day. We'll tell you which at the estimate.

Twice a year suits most homes around here: once after the spring pollen has finished coating everything, and once in the fall. Homes near Route 23, 46, or 202 pick up more road film and often want a third. Interior glass once a year is plenty for most people.

Yes. We schedule visits in advance and send reminder texts before we come. If we're running behind, you'll hear from us rather than wonder where we are.

Yes. A lot of customers around here put the house wash on an annual or every-other-year rhythm and the gutters twice a year, and recurring work is priced better than one-off calls. It also keeps the algae from ever getting established, which is cheaper than dealing with it once it has.

Yes. Everything gets bagged and hauled away. We don't blow it into your beds or leave a pile on the lawn for you to deal with, which is a surprisingly common complaint about the last guy.

We protect and pre-wet the surrounding plants and beds before we start, then finish with a rinse and a walkthrough with you. It's the same care we take on a house wash.

We protect and pre-wet the plants, beds, and gutters below before we start, and we clear debris out of the valleys and gutter lines as part of the job. Then we walk it with you to confirm the result.

We protect and pre-wet plants, beds, and landscaping before we start, which is standard on every house wash. It's part of the job, not something you have to ask for.

For exterior work, no. For interior window cleaning someone has to let us in. Either way we finish with a walkthrough, so if you can be there at the end it's worth it.

A properly soft-washed roof in this area typically stays clean for three to five years. It lasts that long because the treatment kills the algae at the root instead of knocking it off the surface, so regrowth starts from nothing rather than from what was left behind.

What shortens it is the same thing that caused it in the first place: heavy shade, limbs hanging directly over the roof, and a north-facing pitch that never fully dries. Homes under mature canopy in Kinnelon, Towaco and Bloomingdale sit at the shorter end of that range.

Those black streaks are algae. Specifically Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in asphalt shingles. It is not dirt, it does not rinse off, and it does not stop spreading on its own.

Northern New Jersey is close to ideal for it: humid summers, heavy oak and maple canopy, and roof planes that stay shaded and damp for months at a time. It almost always starts on the north-facing pitch and works around from there, which is why one side of a roof can look years older than the other.

Left alone it holds moisture against the shingle and gradually loosens the granules that protect it from UV, so it shortens the life of the roof rather than just the look of it.

Done properly on a clean, dry joint, usually several years before it needs topping up. What shortens it is putting it down on a damp surface or into a joint that wasn't fully cleared first, which is why we don't rush that step.

Look at the joints. If you can see daylight down the side of a paver, or the gap is filled with soil and weeds instead of sand, the sand is gone. The other tell is a stone that rocks slightly underfoot. On a patio that's fifteen or twenty years old, it's usually both.

Ask us about it when we look at your patio. Sealing has real benefits and real trade-offs, and it isn't right for every installation or every stone. We'd rather talk it through in front of the actual pavers than sell it sight unseen.

Usually not. The wood underneath is generally fine; what you're looking at is a weathered gray layer sitting on top of it. Lift that off and the color comes back. Sun, winter moisture, and freeze-thaw cycles do that to every deck out here given a few seasons.

Almost always dirty. That gray film is years of dust, oil, tire marks, and organic growth pressed into the surface, and most people assume it's the color of the slab. When we clean one section the difference is usually startling enough to answer the question.

Left long enough, yes. Moss works its way under the shingle edges and pries them apart, which turns a cleaning problem into a roofing bill. That's the main reason to deal with it before it spreads.

Because that's the side that stays shaded and damp. Moss and lichen take hold where moisture lingers, and everywhere else the roof just collects dust, needles, and debris that hold moisture against the shingles.

Vinyl and painted siding oxidize after twenty-odd years of sun, and the resulting chalky layer traps pollen, road film, and mildew. Most homeowners assume the color is gone for good. Usually it isn't — a proper soft wash brings back most of what was lost for a small fraction of what new siding costs.

Yes. If something isn't right when we're done, tell Nick and he comes back and fixes it. He'd rather make a return trip than leave you looking at a wall you're unhappy with.
