Sash Window Soundproofing in Borehamwood , Hertfordshire

Yes. The two go hand-in-hand. Most noise enters through the same gaps that let in cold air. When we install our draught-proofing system, we use hidden brush seals to close these gaps. This stops the rattling and prevents air-borne noise from entering your home, making the room both quieter and warmer.

In many cases, yes. If your original box frames are in good condition, we can often fit new bespoke sashes containing acoustic glass or double glazing into the existing openings. If the timber sills or lower boxes have rotted, we can perform a sill splice repair using seasoned hardwood to make the frame structurally sound enough to hold the new, heavier glass.

Acoustic laminated glass looks virtually identical to standard glazing. It doesn't have a tint or a strange reflection. The "magic" happens in the invisible interlayer between the panes. Your windows will keep their historic look, and the only difference you will notice is the silence when you close them.

This depends on your specific location. If you are in a conservation area with an Article 4 direction, like many parts of Wandsworth and Clapham, you may need permission to change from single to double glazing. However, timber repairs and draught-proofing usually don't require consent. Charlie Burgess can advise you on the local rules for your specific street during the initial survey.

While no window can block 100% of sound, upgrading from leaky single glazing to acoustic double glazing can reduce perceived noise by up to 50-70%. This is the difference between hearing every car engine and feeling like the traffic is a distant hum.

Acoustic glass and double glazing are heavier than original single panes. To ensure your windows still glide smoothly, we rebalance the entire system. This involves opening the weight pockets and adding lead or cast iron counterweights to match the new sash weight. We also replace old cords with heavy-duty wax-impregnated cotton cords to ensure long-term durability.
