Window Cleaning That Leaves Zero Streaks Behind
Overview

Why choose us for Window Cleaning.

Most homeowners asking about window cleaning want to know two things: what it costs and whether a pro is actually worth it over doing it themselves. The honest answer is that cost varies widely based on how many windows you have, whether you need interior and exterior or just one side, and how long it's been since they were last cleaned. What doesn't vary is the result when it's done right with the right tools: no streaks, no water spots, no missed corners. If your windows haven't been touched in over a year, call (919) 600-1277 and Andrew's crew will get out there and give you an accurate quote before any work starts.

A standard residential window cleaning for a single-story home runs less than a full exterior detail job, but multi-story homes, picture windows, or screens that need separate attention push the price up. Market rates for full residential window cleaning typically run from a few hundred dollars into the $500 to $800 range for larger homes with significant window counts, though the scope of work is what really drives it. Andrew's team cleans inside and out, wipes down sills, and takes care of screens separately when needed. We've paired window cleaning jobs with gutter cleaning and house soft washing on the same visit, which saves you from scheduling separate crews on separate days. Every job is different -- contact Diamond Residential for an accurate estimate.

What We Actually Do on a Window Cleaning Visit

Andrew's crew doesn't show up with a spray bottle and paper towels. We work with professional squeegees, extension poles for second-floor windows, and purified water systems that eliminate the mineral deposits responsible for spotting. Each window gets scrubbed, squeegeed, and detailed at the edges. Interior glass gets the same treatment -- we're not cutting corners on the inside because nobody sees us do it. Sills get wiped. Screens get removed, rinsed, and reinstalled. You'll notice the difference in how much natural light comes through when the job is finished. If your home hasn't had a professional cleaning in a few years, the first visit takes longer -- that's just the reality of built-up grime, hard water scale, and oxidation on the glass.

What Sets a Professional Window Cleaning Apart

Here's what the DIY approach misses, and why it matters for your home.

Purified Water, Not Tap

Tap water leaves mineral deposits on glass as it dries. Professional systems use purified water that evaporates without spotting -- that's the difference between a squeaky-clean finish and a window that looks worse after cleaning than before.

Extension Reach Without the Ladder Risk

Second and third-floor windows get skipped in most DIY attempts because the ladder angle is awkward and the risk is real. We've got the poles and training to clean upper windows safely from the ground or with proper ladder positioning.

Screens Done Separately

A dirty screen in front of a clean window still blocks light and traps dust. We pull screens, clean them separately, and reinstall them. Most homeowners don't realize how much of the grime on their glass is actually on the screen.

Sill and Frame Detail

Sills collect dead insects, water staining, and mildew in humid climates. We wipe them down on every visit. Skipping the sills is what separates a thorough job from a half-done one.

Same-Day Bundling with Other Services

We regularly pair window cleaning with solar panel cleaning, gutter work, or soft washing in a single visit. One crew, one appointment, one less thing to schedule.

When to Call a Pro Instead of Doing It Yourself

If you've got a single-story ranch with eight windows, you can probably manage with a good squeegee and some time. We'll be honest about that. But if you're looking at a two-story home, large picture windows, or glass that hasn't been cleaned in two or three years, the DIY route usually ends with streaks, missed spots, and a frustrating afternoon. Hard water stains -- common throughout the greater Charlotte metro -- require specific treatment that a spray bottle won't touch. And if your windows have mold or oxidation on the frames, that's a sign the siding and exterior around them may need attention too. Check out our blog on professional vs DIY window cleaning if you're on the fence -- it breaks down the actual differences so you can make the call yourself.

How Often Your Windows Actually Need Cleaning

Twice a year is the standard recommendation for most residential homes -- once in spring after pollen season and once in fall before the weather turns. If you're near a construction zone, a heavily wooded lot, or a road with significant traffic, every quarter makes more sense. Pollen in spring is brutal on glass and screens, and if you wait until summer to deal with it, it's had weeks to bake on in the heat. Jessica Castillo said it best after we got to her place: the screens were all yellow from pollen and needed serious work. That's not unusual. We see it constantly in spring. Our blog on how often to clean your windows goes deeper if you want the specifics by season.

  • Diamond Residential did an outstanding job on our rooftop terrace. They removed all of the pavers and the pedestal supports underneath, cleaned out years of debris that was preventing the roof from draining properly, and carefully put everything back in place. During the work, they also found a few roof issues we didn’t know about and repaired them before they became bigger problems. They even completed some drywall repairs, and everything turned out great. Communication was excellent from start to finish, and they were incredibly responsive and efficient. What I expected to be a stressful, complicated project ended up being one of the easiest home repairs we’ve dealt with. I wouldn’t hesitate to recommend Diamond Residential.

  • We’ve had a great experience working with Drew. He does quality work and makes the whole process seamless. Will be looking to reschedule later this year to keep our windows spotless and gutters clean!

Window Cleaning Questions, Answered Straight

What is the average cost to have house windows cleaned?
For a typical single-story home, professional window cleaning runs roughly $150 to $300. Two-story homes, homes with large picture windows, or properties that haven't been cleaned in years will run higher -- $400 to $800 is common for full interior and exterior service on a larger home. Screen cleaning and hard water treatment add to the total. Every job is different -- contact Diamond Residential for an accurate estimate.
How much should I expect to pay for a window cleaner?
Per-window pricing is one model -- usually $5 to $15 per pane depending on size and accessibility -- but most residential jobs get quoted as a flat rate for the whole home. Interior and exterior together costs more than exterior only. Second-floor windows that require ladders or extension poles also factor into the quote. Skimping on a cheap quote usually means someone's cutting a corner -- either skipping screens or doing exterior only and calling it done.
What is the best price for window cleaning?
The best price isn't the lowest one -- it's the one where the crew actually shows up, cleans inside and out, handles your screens, and doesn't leave streaks. Getting multiple quotes is smart. What to compare: does the price include screens? Interior and exterior? Hard water stain removal if needed? A quote that sounds low because it's exterior-only isn't an apples-to-apples comparison with a full-service visit.
What is the best thing to clean windows with?
Professionally, purified or deionized water combined with a scrubber and a quality squeegee produces the cleanest result. Purified water leaves no mineral residue as it dries, which eliminates spotting entirely. For DIY between professional visits, a small amount of dish soap in distilled water with a rubber-bladed squeegee works better than commercial sprays, which often leave a film that attracts dust faster.
How do you remove hard water stains from residential window glass?
Hard water stains -- the white mineral deposits that form from sprinkler overspray or rain running over concrete -- require acidic cleaners like diluted white vinegar or commercial calcium and lime removers. Standard cleaning won't touch them. The longer they've been there, the harder they are to remove without risk of etching the glass. Stubborn cases may need a light buffing compound. This is one area where attempting DIY with the wrong product can permanently damage the glass.
Is it worth cleaning the inside of windows too, or just the outside?
Interior glass picks up cooking grease, smoke residue, fingerprints, and condensation staining -- especially in kitchens and bathrooms. Cleaning exterior only leaves a visible haze on the interior surface that becomes obvious on bright days. If you're paying for window cleaning, cleaning both sides in a single visit is almost always worth the marginal additional cost. Most homeowners are surprised how different the natural light looks when both surfaces are clean.

Most homeowners are surprised how much natural light changes when both surfaces are done in the same visit. We include interior cleaning unless a customer specifically asks for exterior only.
