Spring Window Cleaning Checklist for BC Homeowners

Why Spring Is the Most Important Clean of the Year

BC winters are hard on windows. From November through March, moisture cycles through freeze-thaw patterns that pull minerals out of concrete and stucco and deposit them on glass. Hard water from roof runoff leaves calcium and silica deposits that don't wipe off — they etch into the surface over time. Pollen arrives in April and May, coating everything in a fine yellow film that mixes with dew and bakes into the glass on the first warm days. The case for a thorough spring clean isn't just aesthetic. Mineral deposits that sit on glass for two or more seasons start to bond chemically with the silica in the glass itself. At that point, standard cleaning won't remove them — you need hard water stain treatment, which is a more involved process. Getting ahead of it in spring costs less than treating it in fall. For Shuswap-area homes specifically, spring also brings construction dust, agricultural runoff during freshet, and debris from wind events in March and April. If your home is anywhere near the lake, you're also dealing with elevated mineral content in the air from water evaporation. Spring is the reset — don't skip it.

Step 1: Inspect Before You Clean

Before touching anything, walk the exterior of your home and assess. Look for: - Failed caulking or cracked glazing compound around window frames - White mineral deposits or streaking on glass (indicates hard water residue) - Mold or mildew on frames, particularly north-facing windows with limited sun - Debris in window tracks and weep holes - Gutter sections that are sagging, pulling away from fascia, or visibly overflowing from spring melt - Screen tears or bent frames from winter wind Inspection first matters because cleaning over a failed seal pushes water into the wall cavity. If you find cracked caulking, flag it for repair before the exterior clean. Similarly, clogged weep holes cause water to pool on sill edges and stain frames — clear them before the glass work starts.

• Check caulking around all exterior frames — look for gaps, cracks, or separation
• Identify any white mineral streaking on glass surfaces
• Look for mold or mildew on frames, especially north-facing windows
• Check that weep holes at the bottom of frames are clear
• Assess gutters for debris, sag, or overflow damage from spring runoff

Step 2: Gutters Before Windows

If your gutters are full of debris from fall and winter, clean them before the windows. This sounds obvious, but it's the most commonly skipped step. Here's why it matters: spring rains will flush gutter debris down and across your fascia, soffit, and upper windows. Clean windows below clogged gutters will be dirty within two weeks. Spring gutter cleaning in the Shuswap also catches early nest building by birds and small animals that seek out sheltered gutter sections in March and April. A clogged gutter overflows onto window frames and sills, causing the same mineral staining as hard water from the roof. Professional gutter cleaning in Salmon Arm starts from $189 (assessed on-site). It's worth doing before the window job — not after. The sequence is: gutters cleared, any repairs flagged, then windows cleaned top to bottom. That order protects the window work.

Step 3: The Cleaning Sequence — Top to Bottom, Outside to Inside

The order of operations for spring window cleaning follows one rule: dirty water flows down, so always work from top to bottom. Never clean a lower window before the one above it. For exterior cleaning: start at the highest windows, work across each floor, then move down. Clean frames and tracks before the glass — debris from frames will otherwise land on cleaned glass. Rinse tracks and weep holes with low-pressure water to flush loose material before wiping. For interior cleaning: remove and clean screens first, then clean interior glass. Interior glass in BC homes accumulates cooking vapors, dust, and condensation residue over winter. In older homes, you may find a film from gas furnace operation near drafty frames. If you have hard water staining that standard cleaning doesn't remove, don't scrub harder — you risk scratching. That's a job for a professional with the right chemical treatment and the knowledge to avoid etching the glass further.

• Always work top floor to bottom floor — never bottom up
• Clean frames and tracks before glass to avoid recontaminating clean surfaces
• Remove and clean screens separately before reinstalling
• Interior glass last — it stays cleaner during exterior work
• Flag persistent white deposits for hard water stain treatment, not more scrubbing

Step 4: Check Hard Water Risk Zones

Hard water staining is the most common and most overlooked window problem in the Shuswap. The region's mineral-rich water supply means that any window getting regular water contact — from irrigation spray, roof runoff, or even heavy fog — is at risk. High-risk zones to check during your spring inspection: Windows adjacent to irrigation systems or hose bibs that get regular spray overshoot. Windows on the downhill side of the roofline where runoff concentrates. Lower-level windows below planters or raised garden beds. Any window near a driveway that gets regular vehicle wash splatter. Early hard water deposits look like a faint white haze or light streaking. They're still treatable at this stage. Once they develop into raised, rough-textured deposits or cause a visible etching pattern in bright light, you're looking at more intensive treatment. Spring is the time to catch and treat early deposits before they compound over a summer of heat and UV exposure.

Hard water stain removal in Salmon Arm starts from $189 (assessed on-site). If you're unsure whether what you're seeing is mineral deposit or something else, a professional assessment will tell you quickly.

What to Skip and What to Book Out

Not everything on the spring list needs to be done at once or done by you. Here's a practical split: DIY-appropriate tasks: interior glass cleaning, screen removal and washing with mild soap, clearing visible debris from window tracks, checking and replacing weatherstripping. Book out: exterior second-story or above windows, hard water stain treatment, any window cleaning requiring ladder work above 10 feet, gutter clearing, and any cleaning that touches solar panels or skylights. The risk calculation for ladder work is straightforward — falls from ladders are the leading cause of home injury in BC. A professional window cleaning job for a standard Salmon Arm home starts at $169. That's the cost of one ER visit copay for context. Spring booking fills fast in the Shuswap — April and May are the busiest months of the year for window cleaning companies in the region. If you want a May clean, call in April.
