Can You Fix Rotten Wooden Sash Windows?

Finding rotten wood in the frame, sill, or sash box of your timber window can fill you with dread. Whether you have a bijou Victorian terraced house or a sprawling heritage property, the thought of the complex work involved in repairs can give you a sinking feeling.

There can also be the worry of compromising original window details or even damaging the décor in your home. However, working with a sash window specialist can relieve you of all of these concerns.

So, going back to the question: Can you fix rotten wood in sash windows? Yes, you can, but it’s a job that needs an expert’s touch. In fact, most of the repair work carried out by sash window specialists, like Ventrolla, involves replacing rotten timber. They have a tried-and-tested process where decaying timber in the units, frame or sill is removed, and where necessary, new wood is spliced in.

 

The unique challenge of restoring windows in heritage homes

Where historical properties are concerned, expert restorers have to be especially careful to retain design features that are sympathetic to the property – and preserve any other external or internal detail that is integral to its historical importance.

But what does that entail? Well, the windows should keep their authentic features—or at least look like the originals. This generally means focusing on retaining historically accurate design details, like decorative mouldings on Victorian windows. If a window is too far gone to repair, it could also mean making replacements from high-quality, lasting materials, mirroring the design detail accurately, and using hardware that’s in keeping with the era. Most often, it’s a mix of all of these.

Protecting the décor of the home is often down to the homeowner, who can be instrumental in the preparation stage. We’ve looked at the steps you can take to help in this article.

What wood should be used to ensure lasting quality?

Sash windows were most often made of hardwood originally. If new timber needs to be spliced in or replacement sills, boxes, or frames need to be made, Ventrolla can be relied on to use quality replacement wood that will stand the test of time and give you the peace of mind that your windows will last. But we also take responsibility for sourcing sustainable wood.

Listed Building? Conservation Area? What now?

When it comes to properties with protected status, renovations—even repairs to rotten wood—may be governed by strict guidelines.

As a listed property owner, Listed Building Consent is required for most types of work that affect the special architectural or historic interest of your home. This will be obtained from your local planning authority. The best place to start is with your local conservation officer. Ask them if consent will or will not be needed. It’s a good idea to find out upfront before work gets underway.

If your home is in a conservation area, it may be subject to Article 4 Directions. This means that lots of types of work, from replacing a window to changing gutters, will need planning consent. Local authorities set these rules themselves to protect particular details of local buildings.

And for those living in an Area of Outstanding Natural Beauty (AONB), there is often a board representing that particular area, which must be consulted when it comes to planning applications. This ensures consistency in the decisions made. If you’re not sure whether your home is in an AONB, you can also ask your local authority here.
