• Rattling: Loose-fitting sashes that move when the wind blows or traffic passes.
• Operational Failure: Windows that are painted shut or have snapped sash cords.

Frequently Asked Questions (FAQ)

1. Do I require planning authorization to refurbish my sash windows?

For the most part, basic repair work and draught-proofing do not require planning approval. Nevertheless, if your property is "Listed," you must consult your Local Planning Authority (LPA) before changing the glazing (e.g., from single to double glazing).

2. How long does the repair process take?

For a basic terraced home with 4 to six windows, the procedure normally takes 3 to 5 days. Many companies finish the work on-site, using mobile workshops to decrease disturbance.

3. Can draught-proofing actually make my home warmer?

Yes. Expert draught-proofing eliminates the spaces that allow cold air to go into and warm air to escape. It is frequently cited as one of the most affordable ways to enhance the Energy Performance Certificate (EPC) ranking of a period home.

Typically, yes. If the initial lumber is in great condition and the sash box is deep enough, "slimline" double glazing (which is only 11mm-- 14mm thick) can be retrofitted into the initial sashes.

Seldom. Windows are generally stuck due to "paint-bonding," where years of thick paint layers have merged the sash to the frame. A professional company can securely release these and sand them back to a smooth, functional finish.

6. Will refurbishment aid with outdoors sound?

Considerably. The main source of noise in old windows is the space between the moving parts. The installation of a pile-seal draught-proofing system fills these spaces, creating an acoustic barrier that especially minimizes street sound.
