7 Common Mistakes to Avoid When Buying Blinds
Blinds are a long-term investment that shapes how a room looks, how well you sleep, and how much you pay in heating each Calgary winter. Yet most costly regrets trace back to a handful of avoidable errors made before anything is ordered. This guide walks through the seven mistakes we see most often, why they happen, and exactly how to sidestep each one — so your window coverings fit right, function well, and last for years.
Mistake 1: Choosing the wrong opacity
Opacity is the single biggest driver of whether you love or return your blinds. Many buyers pick a fabric on looks alone, then discover a 'light-filtering' shade lets in far more light than they wanted in a bedroom — or that blackout fabric makes a home office feel like a cave. Opacity should be matched to how each room is used, not chosen room-wide by default.
- Bedrooms and nurseries: blackout fabric or a blackout roller for true darkness and better sleep
- Living rooms and kitchens: light-filtering or sheer for glare control while keeping the space bright
- Home offices facing east or west: dual/zebra blinds so you can dial light up or down through the day
- South-facing rooms: solar fabrics that cut UV and heat without fully blocking the view
Mistake 2: Ignoring child and pet safety
Corded blinds remain one of the leading hidden hazards in homes with young children or pets. Buyers often overlook this because the showroom sample has a tidy cord — but installed at window height, a looped cord is a strangulation risk. Health Canada regulations now restrict long accessible cords on new blinds, and the safest path is to design cords out entirely.
- Choose cordless, spring-lift, or wand-operated blinds for any room a child can access
- Consider motorized blinds — no cords at all, and ideal for hard-to-reach or high windows
- If you keep corded units elsewhere, use cord cleats or tensioners mounted well out of reach
Mistake 3: Buying on price and getting a cheap mechanism
The fabric is what you see, but the mechanism is what you touch every day. Bargain blinds often cut costs on the headrail, clutch, and brackets — the parts that actually wear out. A shade that jams, drifts down on its own, or has a chain that snaps within a year costs far more to replace than the few dollars saved up front. Judge quality by the hardware, not just the swatch.
- Look for smooth, self-locking lift systems and metal (not brittle plastic) internal components
- Ask what the headrail and clutch are made of and whether parts are individually replaceable
- Weigh motorized options for large or frequently used windows — quality motors outlast cheap manual clutches
Mistake 4: DIY measuring and ordering the wrong size
Custom blinds are cut to your numbers, so a measuring mistake is usually non-refundable. The common errors are measuring only one point across a window (frames are rarely perfectly square), forgetting to specify inside versus outside mount, and rounding the wrong way. Even a quarter-inch off can mean light gaps down the sides or a shade that won't fit the recess.
- Measure width and height in three places and record the tightest (inside mount) or largest (outside mount)
- Note obstructions: cranks, handles, tile, and trim depth all change the order
- For made-to-measure orders, a professional measurement removes the guesswork — and the risk
Mistakes 5 & 6: Wrong mount type and skipping the warranty
Inside mount sits inside the window recess for a clean, built-in look; outside mount fixes to the wall or frame above the opening. Choosing wrong affects appearance and light control — shallow recesses, tile, or crank windows often rule out inside mount entirely. The final mistake is ignoring what happens after the sale: a blind with no meaningful warranty, or one installed unevenly, becomes a daily annoyance. Ask exactly what the warranty covers before you commit.
- Inside mount: best for deep, square recesses and a minimalist finish; outside mount blocks more light and can make a window look larger
- Skylights and doors need specialized systems — track-guided skylight blinds and no-drill perfect-fit door blinds
- Confirm warranty length and whether it covers fabric, mechanism, and motor separately
- Use professional installation for wide, heavy, or motorized units to keep the shade level and protect the warranty
How to avoid all of these in Calgary
Nearly every mistake above comes from deciding without seeing fabrics in your own light or measuring without a trained eye. That is exactly what a free in-home consultation solves. A Sunleo consultant brings real samples to your Calgary, Airdrie, Okotoks, or Cochrane home, checks opacity against your actual windows and light, recommends the right mount and child-safe operation, measures precisely, and explains the warranty before anything is ordered.
- See true opacity and colour in your own daylight, not under store lighting
- Get exact measurements and mount advice for each window
- Understand the mechanism, safety options, and warranty before you commit
