ByBritish_Style_Society

When you’re renovating your home, some important tips and tricks can make anything you do yourself more successful. For some, fixing windows might be part of the home renovation project you’ve got ongoing, and before you get started, you want to make sure you have all the right equipment

Selecting the right window screws, for example, is a crucial piece of equipment for the structural integrity, energy efficiency, and longevity of the windows themselves.

When your windows are fixed with high-quality and properly installed fasteners, it can help reduce water intrusion by up to 80%, enhancing energy savings too.

Best materials for long-lasting screws

To ensure longevity and prevent rusting in exterior applications, it’s best to choose materials that are designed to resist corrosion. 

Stainless steel

The best choice for durability and resistance to all environments is certainly stainless steel. This is often the most commonly used type for general use and durability in all environments. 

Non-ferrous materials

This type of material is essential for preventing rust, especially when you’re working with wood in particular.

Zinc-plated/galvanized

A reliable and cost-effective option for corrosion resistance is zinc-plated or galvanized metal.

Matching materials 

It’s worth exploring the option of aluminum screws for aluminium frames to avoid electrolysis. This can lead to premature failure of the windows as a result.

Choosing the right type of screw

When picking the right type of screw, there are many screws to consider. Here are some examples:

  • Self-tapping screws – Ideal for aluminium frames, which don’t require pre-drilling and save time.
  • Countersunk heads – Recommended for aluminum and uPVC frames to ensure a flush finish. 
  • Fine thread screws – Best for aluminum to ensure a secure grip without it stripping.
  • Hardened masonry screws – Necessary for fixing frames into concrete or brick.

Key installation tips for durability

To help ensure the durability of the windows you get installed, here are some key tips to keep them lasting for as long as possible.

Don’t overtighten

Especially when it comes to window frames like uPVC, over-tightening can strip the plastic threads. This causes leaks and reduces structural integrity – which you don’t want for your windows!

Use proper tools

The right power tools are important, so a power drill used on a low control setting is handy. A torque screwdriver is useful to ensure the correct tightness. 

Pre-drill pilot holes

This is crucial when working near glass or with delicate materials. This preparation helps to prevent damage from occurring. 

Length matters 

The length of screws really matters when it comes to window screws, so you should ensure screws are long enough to provide adequate holding power.

Pan head screws are commonly recommended for wood, penetrating at least 1-½ inches.

Strategic placement

The strategic placement of screws is important. It’s good to put 2-3 screws on each side, but avoid fastening through the bottom frame in order to provide drainage.

Maintenance for lasting performance 

There are a couple of simple maintenance tips for the lasting performance of your windows. 

Annual inspection

Checking screws for tightness and signs of wear is important to do at least once a year. 

Lubrication

Using acid and resin-free grease is helpful to use on moving parts, but try to avoid sprays as this can attract dirt.

Window screws that last will also help maintain windows for a long time, so that you can get the best for your investment.
