Windows That Actually Stay Clean

You know the frustration. You spend your Saturday morning cleaning windows, and by the time you finish, the first ones already look streaky. Or worse, you’re staring up at second-story windows wondering if it’s worth risking your neck on a ladder.

Professional window cleaning changes everything. Your windows stay clearer longer because we use the right techniques and commercial-grade solutions. No more water spots that show up as soon as the sun hits the glass. No more streaks that make your windows look worse than before you started.

The difference isn’t just what you see from outside. Clean windows transform how your home feels from the inside – more natural light, clearer views, and that satisfaction of knowing it’s done right. When neighbors walk by, they notice. When you’re showing your home, it matters.

Harmony Grove Window Cleaning Company

We Know Maryland Windows

High Pro Power Washing Service Inc has been serving Harmony Grove and Howard County for years, and we’ve learned a few things about Maryland windows. The pollen in spring, the humidity in summer, the way winter weather leaves its mark – we know what works here.

We’re fully licensed and insured, which matters more than you might think when someone’s working around your home with ladders and equipment. Our team uses professional-grade squeegees, eco-friendly cleaning solutions, and techniques that actually prevent streaking instead of just hoping it doesn’t happen.

You’re not hiring the cheapest option in town, and that’s intentional. You’re hiring people who show up when scheduled, do the job right, and stand behind our work.

Window Cleaning Process

Simple Process, Professional Results

We start with a free estimate that covers exactly what you need – interior, exterior, or both. No surprises, no upselling on services you didn’t ask for. We’ll walk around your property and give you a clear price based on what we see.

On cleaning day, we arrive with everything needed to do the job right. We pre-treat the glass to loosen dirt and grime, then use professional squeegees and solutions that don’t leave residue. For interior windows, we protect your floors and furniture. For exterior work, we handle the ladder safety so you don’t have to think about it.

The final step is a quality check. We look at every window in different lighting to catch anything that needs attention. You shouldn’t have to point out spots we missed – that’s our job. When we’re done, your windows should look like new installations.

Residential Window Cleaning Services

What's Included in Every Service

Every window cleaning service includes exterior glass cleaning, frame wiping, and sill cleaning. We remove spider webs, wasp nests, and built-up debris that makes windows look neglected. Interior cleaning covers the glass, frames, and sills without leaving water damage or cleaning residue on your floors.

We bring our own water and equipment, so you don’t need to worry about hose access or storage. Our cleaning solutions are safe around pets and plants – important in Maryland where many homes have landscaping close to windows. We also clean storm windows and screens when needed, because clean glass behind a dirty screen defeats the purpose.

For homes in Harmony Grove, we understand the seasonal challenges. Spring pollen removal requires different techniques than winter salt residue. We adjust our approach based on what your windows actually need, not a one-size-fits-all method that works okay everywhere and great nowhere.

How often should I have my windows professionally cleaned?

Most homeowners in Maryland benefit from professional window cleaning twice a year – once in spring after pollen season and once in fall before winter weather hits. If you live near busy roads or have large trees around your home, you might want quarterly cleaning. Commercial properties typically need monthly or bi-monthly service depending on foot traffic and environmental factors. The key is consistency – regular cleaning prevents buildup that becomes harder and more expensive to remove later.
We clean windows year-round, but we won’t work in dangerous conditions like ice storms or high winds. Winter window cleaning actually works well – there’s less pollen and dust, and clean windows maximize the limited natural light during shorter days. We avoid cleaning when temperatures are below freezing because solutions can freeze on the glass. If weather forces us to reschedule, we’ll work with you to find the next available date that works for both of us.
The biggest difference is in the tools and technique. Professional squeegees create smooth, streak-free results that household squeegees from the hardware store can’t match. We use commercial cleaning solutions that don’t leave residue, and we know how to work with different types of glass and window configurations. Most importantly, we can safely reach second and third-story windows without putting anyone at risk. DIY cleaning often leaves streaks, water spots, or missed areas that become obvious once the sun hits the glass.
Yes, we use eco-friendly cleaning solutions that won’t harm your landscaping or pets. This is especially important in Maryland where many homes have gardens and outdoor living spaces close to windows. Our solutions break down naturally and don’t contain harsh chemicals that could damage plants or create runoff problems. We’re also careful about overspray and will cover sensitive plants if needed. If you have specific concerns about particular plants or pet sensitivities, let us know during the estimate and we can adjust our approach.
A typical single-story home takes 1-2 hours for exterior windows, while a two-story home usually takes 2-3 hours. Interior cleaning adds about 30-45 minutes depending on the number of windows and furniture that needs to be moved. Homes with lots of divided-light windows or windows that haven’t been cleaned in a long time take longer. We’ll give you a time estimate along with your price quote so you know what to expect. We work efficiently but never rush – the goal is getting it right, not getting it done fast.
Yes, we provide free estimates for all window cleaning projects in Harmony Grove and surrounding areas. We prefer to see your property in person because window count, accessibility, and condition all affect pricing. During the estimate, we’ll identify any potential challenges like hard water stains or damaged screens that might need special attention. We’ll give you a clear, written quote that covers exactly what’s included so there are no surprises on service day. Most estimates take 10-15 minutes and can often be scheduled the same week you call.
