Wood windows are popular for their rustic character and classic appeal. Compared to vinyl and aluminum, their natural material is vulnerable to the effects of the elements. However, there are some steps you can take to protect them from damage. To help you care for your units, here is a guide to the preventative maintenance you can do to prolong their lifespan.

Why Proper Maintenance Matters

Made of natural materials, wood windows are vulnerable to damage from rain, wind, and pests. Moisture can result in warping, breaking, or rotting over time. It can also attract termites and other critters. To prevent this, you’ll need to regularly inspect your fixtures and repair minor issues before they worsen or warrant replacement. Preventive maintenance will help protect your windows from the elements and reduce the need for repairs.

How to Care for Wooden Windows

Cleaning

Debris and grime build up on the exterior and can conceal problems like cracking, peeling paint, and mildew. To make sure you spot issues as they come up, plan to clean your windows at least once a year. When cleaning, mix a mild detergent with warm water and use a soft-bristled brush or sponge to scrub the surface. If you discover cracks on the frames, seal them with wood filler. 

Staining or Painting

Once your wood windows are clean, you can stain or paint them. This is recommended every four years. Not only will this ensure the windows look new, but top finishes and coats create a barrier against weathering. 

Whether you’re using paint or a stain, prep the surface by sanding it. Cover the glass with painter’s tape to prevent scratches or spatters and use fine-grit sandpaper to remove the old finish and mildew.

If you choose to paint your wood windows, make sure to apply oil-based primer first to help the color adhere. Dry it completely before applying two coats of water- or oil-based paint. To preserve the natural look of the wood, opt for staining. Use an oil-based gel stain for faster application, but if your windows are made of softwood, apply a conditioner before staining. For better protection against weathering, top it off with two coats of polyurethane sealant.

Caulking

Once your units are clean and polished, caulk the outer edges to ward off moisture and improve insulation. Opt for exterior caulking instead of the one used for interior applications to ensure better protection. Use it around the entire fixture to close off gaps.
