A Complete Guide to Getting It Right the First Time

Installing window curtains appears to be an easy home upgrade until it’s not. Crooked blinds, shades that do not roll smoothly, or shutters that sag with time can all be caused by an incorrect measurement, a misaligned bracket, or the use of the wrong anchoring. In the humid, sun-soaked environment of Orange Beach, Alabama, these errors are exacerbated by coastal circumstances such as salty air, high humidity, and intense UV exposure.

To assist homeowners prevent annoyance and lost money, we’ve put up a comprehensive guide on what to do and what not to do when installing window treatments. Whether you’re doing it yourself or hiring a professional, this is the in-depth guide you’ll need to make sure your shades, blinds, and shutters look fantastic and last for years.

The Do’s: Smart Practices for a Flawless Finish

1. Do Take Precision Measurements (Multiple Times!)

Accurate measurement is not only important; it is necessary. A window that is even slightly out of square (as most are!) can result in apparent gaps or stress on your hardware. That is why the golden rule states: measure three times before ordering or drilling once. For internal mounts, measure the width and height at three positions each: top, center, and bottom. To guarantee a snug but functional fit, select the narrowest width and tallest height.

For outside mounting, add 2 to 3 inches on either side of the window frame to completely block light and increase privacy. This method is particularly effective in places such as bedrooms or media rooms, where light management is critical.

Real-World Example: In Orange Beach homes, which frequently have unique coastal architecture or older structures, no two windows are alike even if they appear to be. A custom-fit Roman shade that fits wonderfully in one window may not suit the one next to it. When measuring windows, approach each one as a unique project.

2. Do Choose the Correct Mounting Style Based on Function and Form

There are two basic installation options: inside mount (inside the window frame) and outside mount (on the wall or trim around the window). The choice affects both beauty and practicality.

  • Inside mounts provide a sleek, built-in look that is ideal for modern and minimalist settings. However, they require a minimum depth inside the frame, typically 1½ to 3 inches, depending on the treatment.
  • Outside mounts are appropriate when the window depth is too shallow or you want to block more light, cover flaws, or make small windows appear larger.

Outside mounts are frequently a better bet for coastal homes due to humidity-induced window frame expansion and contraction. Outside installations provide improved light and heat management, which is especially useful in hot Gulf Coast afternoons.

3. Do Use the Right Tools and Anchors for Your Wall Type

The most common mistake that DIYers make is underestimating the importance of hardware. Standard screws may not be appropriate for drywall, particularly when supporting heavy treatments such as plantation shutters or layered curtain panels.

Use:

  • Drywall anchors are used when mounting into drywall alone.
  • Use toggle bolts or heavy-duty wall plugs for large treatments or high-traffic areas.
  • Wood screws are used when mounting directly into wood frames.
  • Masonry anchors and drill bits if you’re drilling into brick or tile (common in Florida-style patios and sunrooms).

Always check the type of surface you’re drilling into before selecting fasteners. The salty air in coastal communities such as Orange Beach can corrode hardware over time, so use rust-resistant screws and brackets made of stainless steel or powder-coated metals.

4. Do Follow the Manufacturer’s Instructions Closely

Even seasoned professionals refer to the installation guide when working with a new brand or treatment. Why? Because each product has slightly varied specs, including bracket spacing, necessary installation depth, and safety guidelines.

Ignoring these details can lead to issues like:

  • Inconsistent retraction in roller shades
  • Tilting or binding in vertical blinds
  • Voided warranties due to incorrect installation

Manufacturers provide instructions to help you maximize the product’s lifespan and safety. Spend a few more minutes reviewing them, and you’ll save hours of potential rework.

5. Do Ensure Everything is Level and Aligned

Uneven window treatments are one of the most common and frustrating mistakes in DIY installations. Even a half-inch difference might make blinds appear slanted or operate poorly.

Use a bubble level or a laser level when marking your bracket positions. This is especially important for:

  • Wider treatments, where small errors are magnified
  • Grouped windows, where misalignment can disrupt the whole look
  • Layered designs, where curtains and blinds need to align perfectly

THE DON’TS: What to Avoid at All Costs

1. Don’t “Eyeball” the Measurements

Assuming that the dimensions of your window are sufficiently near together is one of the most alluring shortcuts. However, “eyeballing it” is the fastest route to end up disappointed.

A shade will not effectively block light if it is ½ inch too narrow. An excessively tall blind could scrunch up awkwardly at the bottom or hit the sill. Even worse, there might not be any returns or refunds if you have already placed an order for a customized item.

Natural settling may eventually result in minor window frame adjustments in coastal homes. Even if two windows appear to be the same, you should always measure each one separately and avoid using the same measurements in other rooms.

2. Don’t Mount Directly into Weak Surfaces Without Anchors

This is a matter of safety. Window treatments can be hefty, particularly dual-layered systems, wood blinds, and shutters. They might stay up for a few weeks if you’re installing into drywall without anchors, but ultimately, they’ll sag, loosen, or fall out entirely.

Use drill-in studs, toggle bolts, or expansion anchors for optimal performance. Purchase a stud finder if you’re not sure what you’re drilling into; it’s well worth the money.

3. Don’t Ignore Light Gaps or Overhang

Light gaps are a significant problem in blackout rooms, particularly in inside mounts. Slivers of light will frequently pass through the sides of even the best-installed blinds.

To combat this:

  • Consider side channels for blackout roller shades
  • Choose outside mounts with a generous overlap
  • Layer with curtains or drapes for full coverage and a designer finish

You’ll want that extra protection from the hot afternoon sun in rooms that face west, like many Orange Beach beachfront master suites.

4. Don’t Forget About Children and Pet Safety

Loose cords are not only outdated but also dangerous. According to the United States Consumer Product Safety Commission, strangulation hazards related to window cords have resulted in countless injuries and fatalities.

If you’re installing treatments in family homes, particularly in nurseries, playrooms, or wherever a youngster can reach, choose:

  • Cordless options
  • Motorized window treatments
  • Tension pulleys or cleats for securing loop cords

Many companies now offer “Best for Kids” certified products that meet the latest safety standards.

5. Don’t Assume DIY is Always Cheaper

It’s tempting to believe that DIYing your blinds or shades will save you money, but when things go wrong, the expense of fixing poor installation (or replacing broken products) can outweigh the cost of expert assistance.

You should definitely call a pro if:

  • You’re installing motorized or smart shades
  • You’re working with oversized or oddly shaped windows
  • You need help choosing the best materials for high-humidity conditions
  • You want perfect alignment across multiple windows

Local installers also understand climate challenges specific to Orange Beach, like corrosion, sun exposure, and moisture buildup.

A Final Word of Advice

Installing window treatments may appear to be a simple chore, but getting the details right is essential for maximizing design, comfort, efficiency, and durability.

In beachside homes, where sun, salt, and storms are part of daily life, it’s even more critical to invest in:

  • Accurate measurement
  • The right materials
  • Proper support
  • Safe, long-lasting finishes
