View details ↗02Most of our Caltech residential work is on the blocks near Wilson Avenue and Chester Avenue, where older homes have single-pane windows and mature trees that drop pollen onto screens.

We use water-fed poles for second-story and higher windows, and hand-clean lower panes with squeegees and scrapers. West-facing windows near Hill Avenue tend to need more frequent cleaning because they bake in the afternoon sun.
View details ↗06After a remodel or new build near Caltech, glass usually has paint overspray, sticker residue, and construction dust baked onto the surface. We use glass scrapers and hard water remover to get it off without scratching the pane. This is common on renovation projects along California Boulevard and Chester Avenue.
View details ↗07Hard water stains are a constant problem on lower windows around Caltech because sprinklers hit the glass and leave mineral deposits. We use a dedicated hard water remover and glass scraper to lift the spots instead of just wiping over them. If your glass looks cloudy even after a normal cleaning, this is usually the fix.
View details ↗08Screens around Caltech trap dust, pollen, and fine debris from campus activity. We remove each screen, wash it with a soft brush and Simple Green, rinse it, and let it dry before reinstalling. Dusty screens make clean windows look dirty from the inside, so this step matters more than most people expect.
View details ↗09Clogged window tracks are common in older Caltech homes where grit and debris build up in the channel. We vacuum out the loose material, scrub the track with a microfiber cloth and glass cleaner, and clear the weep holes so water drains. This keeps windows sliding smoothly and prevents mold from forming in the sill.
View details ↗10Sills around Caltech collect dust, dead insects, and sometimes mold after the rainy season. We wipe them down with a mild cleaner, scrub any buildup, and dry them so nothing streaks onto the glass below. This is a small step that makes a big difference in how finished the job looks.
View details ↗11Skylights on Caltech homes and buildings get dirty fast because they sit flat and collect everything the wind carries. We clean them from a ladder or roof access point using a squeegee and microfiber cloth, and we check the seal while we are up there. Leaking skylights often start with debris blocking the drainage channel.
View details ↗12Glass doors around Caltech take a beating from handprints, weather, and daily traffic. We clean both sides, wipe the frames, and clear the tracks so the door slides or swings without dragging. Storefronts and office entries near California Boulevard usually need this on a monthly schedule.
View details ↗13Pressure washing around Caltech handles concrete walkways, driveways, and building exteriors that have collected dirt and grime. We adjust the pressure to the surface so we clean without etching concrete or stripping paint. This is common before events or after the rainy season leaves everything looking dingy.
View details ↗14Soft washing is the right approach for Caltech homes with stucco, siding, or painted surfaces that pressure washing would damage. We apply a soft wash solution, let it dwell, and rinse it clean. This removes mold, mildew, and dirt without forcing water behind the siding.
View details ↗15Concrete and asphalt around Caltech collect oil stains, leaf tannins, and general grime. We use a pressure washer and the right cleaner for the surface, then rinse thoroughly. Parking areas and walkways near Wilson Avenue often need this after the fall leaf drop.

View details ↗19Fences around Caltech pick up dirt, mildew, and water stains, especially on the north side where the sun does not dry them out. We soft wash or pressure wash depending on the material, then rinse. Wood, vinyl, and wrought iron all need a different approach.
View details ↗20Clogged gutters are a real problem in Caltech where mature trees drop leaves and seed pods onto roofs. We scoop out the debris by hand, flush the downspouts, and check that water flows away from the foundation. This is worth doing before the rainy season starts.

View details ↗26Torn window screens are common in Caltech homes where screens are older or have been damaged by pets and weather. We replace the screen mesh and spline, then reinstall the screen in the frame. This is a quick fix that makes a big difference in how the window looks and functions.
View details ↗27When a screen frame is bent or the mesh is too far gone to repair, we build a new screen to fit the window. We measure the opening, cut the frame, install the screen mesh, and test the fit. This is common on older Caltech homes with non-standard window sizes.
View details ↗28If your Caltech home is missing screens or you want new ones, we measure, build, and install them. We use durable screen mesh and make sure the frame fits the window properly so there are no gaps. This is a good add-on when we are already cleaning windows.
