If your windows look hazy, spotted, or dull even after a good rainstorm, you are not imagining it.
Knoxville’s frequent rainfall means your windows are constantly exposed to mineral deposits, pollen, and road residue. Those layers dry, settle, and build up over time until your windows stop looking truly clean. It makes sense why your windows may not have looked clear in months.
Our team helps Knoxville homeowners get their glass looking clean again using a water-fed pole system with a purified water rinse. When interior glass needs attention too, that can be included. For larger or more specialized jobs, including high-rise and post-construction work, we have the equipment and trained staff to handle the job properly.
When the crew is done, you’re seeing outside clearly again. No haze, no mineral film, no wondering why your windows still look dull after a rainstorm. And with a purified water rinse, that result typically holds for three to six months.

Not every window is the same, and the right cleaning approach depends on what you have. Here is a clear breakdown of what our team handles and what to keep in mind for your specific situation.
Your exterior glass gets scrubbed using a water-fed pole and rinsed with purified water. That combination removes surface buildup without leaving mineral residue behind to dry back into haze.
The result typically holds for 3–6 months, giving you a longer stretch of clean glass than most traditional approaches can deliver.
If your interior windows, sliding glass doors, or glass panels need attention, that work is available when it’s part of your scope. Each pane gets scrubbed with soap and water, squeegeed clean, and detailed with a towel.
This is especially useful if you have kids or pets, or if your glass doors take heavy daily use. Interior cleaning is not the core focus of this page, but it is available when you need it.
We clean single hung, double hung, and French pane windows, along with glass doors, sliders, and both exterior and interior glass as your job requires. If you have French pane windows, those are quoted at a higher per-window rate because the individual panes take more time and careful work to clean properly.
You’ll see that reflected clearly in your quote before any work begins.
Older windows, leaded glass, and delicate surfaces get a different process. Softer pressure, more deliberate handling, and window spray in place of a scrubber when the glass calls for it.
If you have windows you’ve been nervous to have cleaned before, mention that when you reach out. The team will plan accordingly before arriving at your property.
If your property has windows that require high-rise access, you’re in good hands. We have two certified high-rise technicians on staff with rope-access and rappelling capability, and carry specific insurance for high-rise work in addition to $3 million in general liability coverage.
Water-fed pole equipment, ladders, or harnesses are used based on what your building actually requires. That combination of certified staff and proper insurance gives you real protection that most local window cleaning companies can’t offer.
If your property has just gone through a build or renovation and the glass has picked up construction dust or residue, post-construction window cleaning is available.
Every job is evaluated based on the condition of the glass and what’s on it, so reach out before booking and we’ll talk through the scope honestly.
The water-fed pole system with a purified water rinse means your windows are not just cleaned for the day.
Because purified water leaves no mineral residue behind, there is less film left on the glass to attract the next layer of grime. For homeowners, that means clearer glass for longer between cleanings.
Between professional cleanings, high-contact glass like sliding doors and entry panels can pick up smudges and hand marks faster than the rest of your windows. We have a homeowner video showing how to touch up your windows between professional visits. Ask us for the link when you book.
You shouldn’t have to coordinate two separate appointments for exterior and interior glass. When interior windows are part of your job, the same crew handles everything: scrubbing, squeegeeing, and towel detailing each interior pane in the same visit. One call, one crew, one job done.
If your property requires high-rise window cleaning, the training and insurance behind the work matter. We have certified high-rise technicians with rope-access capability and specific high-rise insurance, in addition to $3 million in general liability coverage.
That gives you more confidence when the job requires specialized access and added safety planning.
If you’ve ever hesitated to book window cleaning because you weren’t sure a crew would handle older or specialty glass carefully, that concern is understandable.
We adjust the process based on what your glass actually needs: softer pressure, gentler technique, and window spray instead of a scrubber when the surface calls for it. You can mention your concerns upfront, and the team comes prepared.
When you are choosing a crew to work on your home, the track record of the company you pick matters. SmartWash is the highest-rated exterior cleaning company in East Tennessee, with more than 600 Google reviews earned through real residential jobs.
Reading through those reviews before you call is one of the most useful things you can do to feel confident in your decision.
Knowing exactly what to expect before, during, and after your service removes most of the uncertainty that comes with hiring any contractor.
Here is how the process works from your first contact through follow-up.
Most quotes are prepared using satellite imaging and real estate photos, so you get an accurate number without anyone needing to visit your property first. When an on-site review makes more sense for a particular job, we arrange one.
After you accept, you receive a confirmation by email and text, a reminder one week before service, and another one 24 hours out. Nothing about your service date should come as a surprise.
When the crew arrives, access is reviewed for every window on the property so the right equipment is used for each area. If interior cleaning is part of your scope, the team can move furniture and start in whichever room works best for your day.
If you’re working from home or someone in the household is sleeping, let us know ahead of time and the crew will work around it.
Every exterior pane gets scrubbed with the water-fed pole and rinsed with purified water. That rinse is what makes results last. Tap water leaves dissolved minerals that dry into film; purified water leaves nothing.
Your results typically hold for 3–6 months, with the actual timeline depending on weather, proximity to trees, pets, kids, and how often high-contact glass like sliding doors gets used day-to-day.
If interior windows are part of your service, they get soap and water, a scrubber, a squeegee, and towel detailing on every pane. If you have older or delicate glass, the approach shifts to softer pressure and window spray in place of a scrubber.
High-rise and post-construction glass is handled based on the specific conditions at your property.
Before the crew leaves, you have the chance to flag anything. If a concern comes up after the visit, call us and our team will come out to take a look.
For ongoing care, quarterly cleaning gives you the best year-round results, with biannual and annual options available if you prefer a lighter schedule.
Understanding what drives the cost of window cleaning helps you know what to expect before anyone shows up at your door. Here is how we price the work, what most homeowners pay, and how combining services can reduce your overall cost.
Your quote is based on a per-window price, not square footage.
For most residential jobs, the total falls between $150 – $650, and the average job comes in at about $200. Plan for the service to take between 1 and 4 hours, depending on your home’s window count and complexity.
Your final price depends on:
If you are already planning to have your house washed, gutters cleaned, roof cleaned, or concrete and patio cleaned, adding window cleaning to the same visit can be a practical way to reduce the overall cost per job.
We offer a multi-service discount when you combine services in a single booking. The exact savings depend on your specific combination and the scope of the work, so no fixed percentage is advertised. For commercial properties, window cleaning pairs well with dryer vent cleaning and pressure washing in a single high-rise service visit.
When you request your quote, let us know what else you’re considering so we can factor that in.
Window cleaning results can be affected by conditions after the job: weather, pollen season, nearby construction. That makes a blanket warranty difficult to apply fairly, so we don’t offer one. What we do offer is simple. If something doesn’t look right after we leave, call us. We come out and take a look the same day, or whenever the concern comes up.
We carry $3 million in general liability and separate high-rise coverage for elevated access work.
Yes, interior window cleaning is available when needed. We clean interior glass using soap and water, a scrubber, a squeegee, and a towel to detail each pane. It is most useful for fingerprints, smudges, hand marks, and high-contact surfaces like sliding glass doors, particularly in homes with kids or pets.
Yes. French pane windows are more time-consuming than standard window types because each individual pane has to be cleaned separately and carefully. That extra work is reflected in the per-window price when we put together your quote.
No. We do not clean storm windows, and screen cleaning is not part of this service. If you have a specific glass situation that falls outside the standard scope, call before booking so we can talk through it.
Yes. We have two certified high-rise technicians on staff with rope-access and rappelling capability. High-rise window cleaning is backed by specific high-rise insurance, which is separate from the $3 million in general liability coverage we carry across all work.
Yes. Post-construction window cleaning is available for properties where glass has picked up debris during a build or renovation. The specific approach depends on the condition of the glass and the type of debris involved, so reach out before booking and we can properly assess the scope.
We recommend quarterly cleaning for the best long-term results. Biannual and annual options are also available. Monthly window cleaning is not part of the standard residential offering.
Typically 3–6 months. Water-fed pole cleaning generally lasts longer than traditional methods because the purified water rinse leaves no mineral residue on the glass. The actual timeline depends on weather, proximity to trees, pets, children, and how often high-contact surfaces like sliding doors get daily use.
Yes. If interior cleaning is part of the job, we can move furniture and start in whichever room works best for your household. If someone is working from home or sleeping in a particular room, let us know and the crew will plan around it.
Not always. Most estimates are prepared using satellite imaging and real estate photos, so no on-site visit is required in the majority of cases. We schedule a site visit only when the property has features that are harder to assess remotely.
Call SmartWash and the team will come take a look. There is no formal process to work through. You call, we come out, and we handle it.
If cloudy, spotted windows have been on your to-do list, this is the straightforward next step. We handle exterior window cleaning with a water-fed pole and purified water rinse, interior glass when your job calls for it, and high-rise and post-construction work for projects that need more specialized handling.
Most residential jobs fall between $150–$650, with the average coming in at about $200 and a quarterly schedule being the most practical way to protect your results year-round. Most estimates are prepared using satellite imaging with no on-site visit required, quotes arrive by email and text, and automated reminders keep your service date on track without extra effort on your end.
