What we do

Everything on the outside of the glass, and the inside

A window visit covers the panes, frames and sills, because cleaning one and not the others shows. On the Seymour Shine Subscription the tracks come with every visit and the inside is part of the year; screens and the rest can be added on or booked on their own.

Exterior Window Cleaning

A full scrub down, polish and detail of every exterior frame, pane, track and sill.

How it goes

Four steps, no packages to decode

01

You get in touch

Call, text or fill in the form. Whatever is easiest. We just need to know where you are and roughly what you have.

02

We quote it

One number, in writing. We start on your virtual quote from the details you send.

03

We clean it

You don't need to be home for us to do the job well. We treat that trust as part of the work.

04

We keep it that way

The Seymour Shine Subscription is what most of our clients choose: a better per-visit rate than our one-time deep clean price, and glass you never think about. If it is not the right fit, say so when you get in touch.

Who you're hiring

The standard came from the service

Aaron Seymour holds a BS in civil engineering, earned a PE license and a PMP certification, and spent five years as an officer in the Navy Civil Engineer Corps before he ever picked up a squeegee. He started Seymour's because he kept seeing the same gap in this trade: crews that show up late, don't communicate, and treat your home like a job site.

What the military drills in is what this company runs on: show up on time or early, communicate clearly, and sweat the details nobody is checking. That has meant 529 Google reviews at a 5.0 average, and the competitors ahead of that count have been at it for a decade or more.

“Their business is a veteran owned business. For us that's a reason to initially hire them. But the quality of the work is the reason they will get our repeat business.”

Window glass covered edge to edge in hard water spotting

Why Boise glass gets spots

The valley's water is hard on glass

Treasure Valley water picks up minerals underground before it reaches your tap: hard enough, in most of the valley, that they stay behind on the glass when the water dries.

On the glass, it shows up as the white haze a paper towel won't touch. It is not dirt. It is calcium and magnesium sitting on the surface, and the longer it sits the harder it is to take off.

Hardness varies street to street

Different parts of the valley draw from different sources, so two houses a mile apart can spot at very different rates.

Wells add iron

Well water in parts of the valley runs harder than city water, and the iron in it oxidizes into the orange staining you already see on sidewalks and stucco.

Sprinklers do the damage

It is rarely the rain. It is one misaligned head hitting the same pane twice a day, all summer, for years.

Light and heavy are different jobs

Light buildup, caught early, comes off during a normal visit when possible. Years of heavy staining is a different job with different tools.

Real jobs, real photos

The same window, before and after

Three jobs, shown the way they actually happened. Drag the line, or use the arrow keys. Every visit carries the same 48-hour quality guarantee and 7-day rain guarantee as the one before it.

For real estate professionals

The finishing touch before a listing goes live

Agents trust us alone in a listing. Clean glass is the smallest job on the listing-prep list, and the one buyers notice first.

As a realtor, finding vendors who are not only skilled but genuinely easy to work with is everything. Seymour's delivered on both… Even areas with visible sun damage came back looking clean and bright. It was the perfect finishing touch before bringing the home to market, and my clients noticed immediately.

Clayton arrived cheerful and ready to clean the windows. He was polite and very thorough. I appreciated his attention to detail and his positive attitude. My windows look amazing!

Jenicee Woodard · Google review

Seymour's Window Washing is top notch. My windows now look fantastic! My tech, Matt went above and beyond getting a painted on screen off without damage to the screen or frame. I'm so happy I found them!

Shari Vaughan · Google review

Seymour's did a great job on my windows on both stories. They were very thorough and did good follow up to make sure I was happy. Clayton was easy to work with and did a wonderful work. I would have them back for sure. They are working hard to provide exceptional service.

Straight answers

Questions we get every week

How often should windows be cleaned in Boise?

More often than most people get to it, and on a schedule rather than when you happen to notice. Glass here takes sprinkler spray, valley dust and hard water, and spotting comes off easily while it is still light. That is what the Seymour Shine Subscription is built for: we set the rhythm around your house when we quote it, and per visit it is a better rate than our one-time price.

What does the Seymour Shine Subscription include?

Every visit includes polishing the glass, removing hard water stains, and cleaning frames, sills and tracks, backed by a 48-hour quality guarantee and a 7-day rain guarantee. Screen handwashing, or doing inside and outside in one visit, can be added on. How often we come out is set around your house when we quote it.

Do I need to be home?

No. Clients and real estate pros are comfortable leaving us alone to work in their homes and listings.

Will hard water spots come off?

When possible, we treat and remove light hard water spots at no extra cost during your service. Heavier mineral staining may require a more advanced restoration service.

Do you do second and third story windows?

Yes. Three-story homes, solar panels on the third story, skylights, a cabin on a sloped hill: it is all in our reviews.

What if it rains right after you clean?

Clean glass sheds rain and dries clear. What leaves spots is dust already on the window when the rain hits it, which is exactly what we just removed. And every Seymour Shine visit carries a 7-day rain guarantee.

Why aren't prices listed on this site?

Because a number posted here would be wrong for most houses. Every house is different, so we would rather understand yours first and quote once than publish a figure we have to walk back. Get in touch and we will give you a real number for your house.
