Streak-free interior and exterior glass, screens, tracks, and sills — for homes and businesses across Renton and the surrounding Eastside.
Windows are the one part of a house that the Pacific Northwest actively works against. Nine months of rain leaves mineral spotting. Douglas fir and cedar drop needles and sap onto sills. North-facing glass grows a green algae film that most homeowners assume is dirt on the outside of the pane and is actually a living organism. By February, most Renton houses are looking at the winter through a filter.
We've been cleaning windows in Renton since 2004, and it is one of the services people are most surprised by — not because the glass gets clean, but because of how much light comes back into the room. Owner Jack Kapala prices the job himself, and the same crew that cleans your windows this year comes back next year, so nobody has to re-learn which windows stick, which screens are brittle, and where the sprinkler head sprays.
Every window job includes the glass itself, the frames wiped down, the sills cleaned, and the tracks vacuumed out. Screens and hard-water mineral removal are quoted as separate named line items rather than assumed — you decide what's worth doing and there are no additions on the invoice you didn't agree to.
Most of our residential window work is in Renton Highlands, Kennydale, Benson Hill, Talbot, Fairwood, and Newcastle. Each of those areas has its own quirk. Kennydale and Newcastle homes are built for the Lake Washington and Seattle skyline views — those are the customers who feel the difference most, because a view home with dirty glass is a view home you stop looking out of. The Highlands and Fairwood have a lot of mature evergreen cover, which means sap, needles in the tracks, and heavier algae growth on the shaded elevations. Benson Hill and Talbot have more single-story and split-level stock where the whole job is straightforward and quick.
If you're on a regular house cleaning schedule with us, interior windows can be folded into a deep clean rather than booked as a standalone visit. Ask Jack which is cheaper for your situation — sometimes it's one, sometimes the other, and he'll tell you honestly rather than selling you the bigger package.
Commercial glass is a maintenance item, not a one-time job. Storefront windows on Rainier Ave S, at The Landing, and along Grady Way collect road film continuously, and the difference between a business that looks cared-for and one that doesn't is usually the glass and the entry door.
We run monthly, quarterly, and semi-annual glass schedules for retail, restaurants, offices, and multi-tenant buildings in Renton. Work is scheduled outside of business hours where access allows. Certificates of Insurance naming your business or property management entity as additional insured are issued at no charge before the first visit.
If you also need interior janitorial, the glass schedule folds into a single monthly invoice — see commercial cleaning in Renton for the full scope.
Late spring (April–June) is the single best window. The heavy rain has stopped, pollen has largely finished, and the glass is carrying everything winter left on it. This is when most Renton homeowners book.
Early fall (September–October) is the second. Getting the glass clean before the wet season means the darkest months of the year are spent looking through clear windows rather than a film. If you only book once a year, this is arguably the higher-value slot.
Move-in and move-out is the third common trigger — glass is one of the most visible things a landlord or buyer inspects and one of the most commonly skipped by the outgoing tenant. If that's your situation, it's usually cheaper bundled into a move-out clean in Renton than booked separately.

Window cleaning is quoted per job, not per pane, because Renton housing stock varies so much — a single-story Benson Hill rambler and a three-story Kennydale view home are very different jobs. Jack asks how many windows you have, whether you want interior and exterior or exterior only, whether screens and tracks are included, and how many stories. You get a firm number before anyone shows up, with no trip charge for the estimate.
Yes, and we quote them as a named line item so you know exactly what you're paying for. Screens are removed, washed, and reinstalled. Tracks and sills get vacuumed and wiped — in the Puget Sound climate that's where the fir needles, moss spores, and grit collect, and skipping it is why some window jobs look dirty again within weeks.
Yes. Multi-story exteriors are routine for us across Renton Highlands, Kennydale, and the Talbot and Fairwood hillsides. We use ladder work and water-fed pole systems depending on the elevation, roofline, and what's underneath the window. We are licensed, bonded, and fully insured for this work — ask for the Certificate of Insurance and we'll send it before the job.
Late spring and early fall are the two sweet spots. Spring clears the winter's accumulated rain spotting, moss spores, and pollen film. Early fall gets the glass clean before the wet season starts in earnest, so you spend the dark months looking through clear windows. Many Renton clients book both and skip the rest of the year entirely.
That's usually hard-water mineral deposit — most often from lawn irrigation heads hitting the glass, or runoff from a gutter or window well. Renton and the wider Eastside have moderately hard water, and once minerals bake onto glass, ordinary washing won't touch them. Mineral removal is a separate process and a separate line item; Jack will tell you at the walkthrough whether the spotting will come out or whether the glass is already etched.
Yes. We handle storefront glass, entry doors, interior partitions, and office glass throughout Renton — including recurring monthly and quarterly schedules for retail on the Rainier Ave S corridor and offices around Grady Way and The Landing. Recurring commercial glass is usually quoted alongside a janitorial scope, but we're happy to do glass only.
For exterior-only work, no — just make sure gates are unlocked and any dogs are inside. For interior work, someone needs to let the crew in. Either way Jack sends a text the day before with the exact arrival time, so you aren't waiting on a four-hour window.
We are licensed, bonded, and insured, and that coverage is exactly what it's for. In practice, the windows most at risk are ones that already have a compromised seal or a hairline crack — the crew flags anything like that before they start and shows it to you, so nothing is a surprise afterward.
Call Jack for a firm quote — no trip charge, no obligation, and a text the day before with your exact arrival time.
