Detailed Sill & Frame Cleaning – Because It’s Not Just the Glass

The Parts Most Companies Skip — We Don’t

At WindowCleaningPros85, we believe a truly clean window includes more than just spotless glass. That’s why we go the extra mile to clean and detail the parts that most companies ignore — the sills and frames. These areas collect dust, debris, mold, and grime over time, and if left untouched, they not only look dirty but can contribute to long-term damage and poor air quality.

Our sill and frame cleaning is part of our complete service approach. We carefully scrub, wipe, and disinfect all visible window sills and frame surfaces, using the right tools and non-toxic cleaners to get the job done right without damaging finishes or seals.

Our Sill & Frame Cleaning Method – Step-by-Step

Visual Inspection and Surface Prep

Visual Inspection and Surface Prep

We begin by examining each window sill and frame for signs of damage, mold, or heavy buildup. This helps us determine the right tools and cleaning method. We’ll also move or protect any items around the windows to keep your home or business clean and undisturbed.

Dust Removal

Loose Debris and Dust Removal

Using soft-bristle brushes and vacuums, we remove loose dirt, cobwebs, and dust from corners, grooves, and ledges. This clears the way for deep cleaning and prevents scratching when moisture is applied.

Cleaner to Frames and Sills

Apply Cleaner to Frames and Sills

We use a plant-safe, pH-balanced cleaning solution that lifts dirt and sanitizes surfaces without harming window finishes. Whether your frames are wood, vinyl, or metal, we adjust the product to ensure safety and performance.

Scrub and Detail Clean

Scrub and Detail Clean

With microfiber cloths, precision brushes, and non-scratch pads, we scrub away grime from the sills, inside tracks, outer frame surfaces, and all corners. We take special care around sealants, caulking, and painted edges to ensure no damage occurs.

Wipe Down and Dry

Wipe Down and Dry

We carefully dry the sills and frames to prevent streaks and moisture spots. For interior windows, we protect your flooring and furniture. For exterior windows, we wipe any drips from siding, trim, or surrounding material.

Final Inspection

Final Inspection and Client Review

Before we call it done, we double-check every sill and frame for any missed spots or stains. Our goal is to leave every surface looking as close to new as possible — clean, dry, and professionally finished.

Why Sill & Frame Cleaning Matters

  • Improves Indoor Air Quality

    Dirty sills and frames can collect allergens like pollen, mold, and dust. Cleaning them regularly reduces airborne contaminants and helps maintain a healthier environment.

  • Enhances Overall Appearance

    Even spotless glass won’t make up for grime on the frame or dust on the sill. Cleaning these areas elevates the appearance of your entire window and surrounding wall space.

  • Extends the Life of Your Windows

    Mold, mildew, and moisture buildup can damage window materials and lead to premature wear. Our process helps preserve seals, prevent rot, and extend the life of your window components.

  • Protects Against Pests and Debris

    Insects, cobwebs, and even small critters often make homes in neglected window sills. Regular cleaning removes attractants and keeps your property looking and feeling clean year-round.

Sill & Frame Cleaning – Frequently Asked Questions

What types of window frames do you clean?

We clean wood, aluminum, vinyl, composite, and painted frames. Our products are chosen to be non-abrasive and safe for all standard window materials. If your frames are older or delicate, we’ll take extra care to ensure no finish is compromised during the cleaning process.

Do you clean both interior and exterior sills and frames?

Yes, our full-service includes both sides. We wipe and sanitize interior sills and frames with great care to protect flooring and window treatments, and we detail all accessible exterior areas including corners and tracks.

How often should sills and frames be cleaned?

Ideally, they should be cleaned 2–4 times per year, especially in areas with seasonal allergens, nearby construction, or heavy outdoor exposure. Businesses with high-traffic windows may need more frequent cleanings to maintain a professional appearance.

Do you offer sill and frame cleaning without window glass cleaning?

Yes. While most clients include this as part of a full window cleaning service, we do offer stand-alone sill and frame cleaning. Just let us know when booking, and we’ll tailor the service to your needs.
