Wooden sash windows are a hallmark of period properties in the UK. With their elegant frames and multi-panelled glazing, they contribute enormously to the charm and character of older homes. If you’re looking to refurbish wooden sash windows, it’s essential to consider the heritage and aesthetic of the property.

However, over time, these windows can become draughty, rickety, and inefficient. Rather than ripping them out and replacing them with modern casements, there are ways to refurbish original sash windows to improve their performance while retaining their aesthetic appeal.

By doing so, you can preserve the heritage of your home while making it more comfortable and energy-efficient.

Evaluating Your Current Sash Windows

Before diving into any refurbishment, it’s crucial to have a proper gander at your current wooden sash windows. This will help pinpoint areas that are crying out for a bit of TLC. Here’s what you should be on the lookout for:

  • Timber frames and sills that are a bit wobbly, showing signs of rot, or have taken a bit of a battering over the years.
  • Sash cords, pulleys, or weights that have seen better days or have given up the ghost entirely.
  • Glazing panes that are absent, sporting cracks, or just not looking their best.
  • Paintwork that’s starting to look a tad tired, flaking away, or has lost its lustre.
  • Any sneaky gaps, little cracks, or other spots where draughts might be making an unwelcome entrance.

Jot down observations for each window, helping you map out a game plan for their refurbishment. For those windows that have seen rougher days, it’s a good shout to get them sorted first. And if you come across frames that have taken a real pasting, it might be worth having a chinwag with a sash window boffin to get their take on the best restoration approach.

Draught Proofing – Combatting Draughts

One of the primary motivations behind giving sash windows a bit of a spruce-up is to up their game in the energy efficiency department. Kicking things off with draught-proofing is a smashing idea, as it can cut down heat loss by a whopping 25%.

  • Pop in some brush or rubber seals where the window sashes meet the frames.
  • Slot in draught-busting strips along the channels where the sashes have their little slide up and down.
  • Fill in any niggly gaps or cracks in the frames with a good-quality sealant.

Mind you, it’s essential to ensure the sashes still operate smoothly after all this. For top-notch results, it’s worth investing in draught-proofing gear specifically designed for sash windows.

Now, onto the task of sorting out those bits of wood that have seen better days.

  • Delicately chip away at the old paint to get a proper look at the damage underneath.
  • For those particularly rotten patches, chop them out and swap in new timber that matches in size.
  • Employ a trusty wood filler to sort out any unsightly cracks or pesky holes.
  • Give it a good sanding down, prepping it for a fresh lick of paint later on.

Tend to any sagging meeting rails and give a bit of TLC to worn-out sills or linings. And remember, it’s always a good idea to keep as much of the original timber as you can – it adds a touch of genuine character, after all.

Revamping the Mechanical Bits

The bits and bobs that make sash windows do their thing – the pulleys, cords, weights, and lifts – often need a bit of a spruce-up.

  • Give those parched pulleys a good oiling and swap out any snapped cords or tatty sash lifts.
  • Tweak the counterbalance weights to ensure the sashes slide up and down like a dream.
  • If there’s a need, pop in some fresh spring balances.

Ensuring your sashes are working tip-top is crucial, not just for keeping draughts at bay, but also to stop the wood from getting all swollen and out of shape.

Reglazing and Refinishing

Finally, when thinking about how to refurbish sash windows you need to complete the rejuvenation with new glass panes and paint:

  • Gently prise out any old, cracked, or absent glazing and pop in fresh panes. A dab of putty will keep them snug.
  • Buff up the window frames, sashes, and trims, then lavish them with a couple of layers of top-notch paint.
  • If the exterior trim and moulding are looking a tad weather-beaten, think about giving them a swap.

With a bit of elbow grease and a keen eye, you can breathe new life into weary sash windows, making them look and work a treat, all while preserving that invaluable old-world allure.

They’ll be shipshape and ready to serve your home faithfully for many more years.
