Common Things That Get Damaged During Post-Construction Cleaning
Why “Regular Cleaning” Can Ruin New Builds in Chilliwack, Hope & Agassiz
Post-construction cleaning isn’t just “a deeper clean.” It’s a high-risk stage of a build or renovation, because finishes may be brand new, still curing, and often covered in fine construction dust that behaves like grit.
When post-construction cleaning is rushed or done by inexperienced cleaners, the result can be expensive damage, call-backs, and delays in occupancy.
Below are the most common materials that get damaged during post-construction cleaning — and the science/guidelines behind why it happens.
1) Windows & Glass: Scratches, Swirls, and Permanent Marks
Most common damage: scratched glass, swirl marks, hazing
This is one of the biggest risks on new builds — especially on heat-treated glass (tempered) and coated glass. Industry guidance warns that scraping or using improper tools can lead to scratching, and some glass surfaces are more prone to visible scratching during cleaning. Cardinal Glass Industries+1
Why it happens
Dry dust contains mineral grit (can behave like sandpaper)
Improper scraping or dragging debris across glass
Razor use on coated surfaces (a known no-go in manufacturer/industry procedures) AGM Glass Fabricators+1
What pros do differently
Identify glass type/coatings first
Use wet methods and safe procedures aligned with architectural glass cleaning guidance VITRUM™ Glass Group+1
2) Natural Stone: Etching and Dulling From Acidic Cleaners
Most common damage: etching (cloudy dull spots), surface wear, permanent dulling
A lot of cleaners use vinegar or acidic products to “cut haze.” That can destroy stone.
The Natural Stone Institute explains that calcareous stones (like marble/limestone) contain calcium carbonate and are sensitive to acids; mild, non-acidic cleaners are recommended. Natural Stone Institute
Stone care guidance also warns that products containing acids (including vinegar/lemon) can dull or etch calcareous stones. MSI Surfaces
Why it happens
Acid reacts chemically with calcium carbonate → etching (not a removable stain)
What pros do differently
Use stone-safe, non-acidic methods
Spot test and follow manufacturer guidance on new installs Natural Stone Institute+1
3) Tile & Grout: Haze, Discoloration, and Surface Scratches
Most common damage: grout haze left behind, discoloration, micro-scratches on tile
After construction, fine residue + improper chemicals can leave a film that looks like “it never got clean.” On some surfaces, aggressive pads can scratch.
Why it happens
Wrong chemistry for the tile/stone type
Over-aggressive abrasion on fresh grout/finishes
Trying to “power through” instead of using correct method
What pros do differently
Match cleaning method to surface type
Avoid acids on acid-sensitive stone (see stone section) Natural Stone Institute+1
4) Painted Walls & Fresh Finishes: Burnishing, Smears, and Sheen Damage
Most common damage: shiny rubbed patches, streaking, peeling, uneven sheen
Fresh paint is often dry but not fully cured. During cure, it’s more vulnerable to scuffing and aggressive wiping.
Benjamin Moore advises waiting at least two weeks for newly painted walls to cure before cleaning, and using gentle methods if cleaning must happen sooner. Benjamin Moore
Why it happens
Scrubbing too hard during early cure
Using strong solvents or harsh products
Over-wet wiping
What pros do differently
Gentle, low-moisture techniques
Spot testing and timing awareness (especially in final cleans) Benjamin Moore
5) Cabinetry & Millwork: Swelling, Peeling, and Edge Damage
Most common damage: MDF swelling, veneer lifting, paint failure on cabinets
Cabinets and millwork look solid, but edges and seams (especially MDF) are vulnerable to moisture and harsh chemicals.
Why it happens
Too much water
Degreasers used like it’s a commercial kitchen
Scrubbing paint/finish before it’s fully hardened
What pros do differently
Minimal moisture and controlled wipe-down
Finish-appropriate product selection
Detail work that avoids flooding edges and seams
6) Fixtures: Etching and Finish Dulling
Most common damage: matte black spotting, dulled chrome, etched finishes
Harsh cleaners or leaving chemistry sitting too long can permanently damage modern finishes.
What pros do differently
pH-appropriate products
Short dwell time
Microfiber + non-abrasive methods
7) HVAC Vents & Returns: Dust Redistribution and “Never-Ending” Residue
Most common issue: dust keeps coming back after you “clean”
If dust gets circulated through air returns and vents, it can re-settle repeatedly. That’s why proper post-construction cleaning focuses on dust removal strategy, not just wiping visible surfaces.
