Sash Window Soundproofing in Leatherhead , Surrey

Our approach to noise reduction starts with the basics of timber window mechanics. We focus on the gaps around the sash where air and sound leak through most readily. By machining hidden, high-performance brush seals into new parting and staff beads, we create a precision-fit seal that acts as a primary barrier against noise. This process not only keeps out the street noise but also eliminates the draughts that often plague older sash windows, leaving your rooms warmer and significantly quieter.

For many homeowners, the ultimate solution for sound insulation is upgrading to A-rated double glazing. We replace single-pane glass with modern, argon-filled units that offer superior thermal and acoustic performance. These slim profiles are designed to fit perfectly into your existing timber frames, replicating the authentic historic sightlines required in many Leatherhead conservation areas. Unlike thick modern replacements, these units maintain the delicate character of your original window profiles while providing the noise reduction you expect from a modern home.

We understand the strict planning controls that apply to period properties in Leatherhead and across Mole Valley. When your home is subject to conservation area restrictions or listed building status, replacing the entire window is rarely the first step. Our restoration process preserves your original box frames and external mouldings, replacing only the sashes or glass where necessary. This ensures you remain compliant with local planning authority guidelines while achieving the modern soundproofing standards you require.

Every project we undertake is guided by a commitment to quality joinery and material longevity. We use seasoned timber for all repairs, ensuring that your windows are built to last for decades. As a FENSA registered specialist, we carry 2 million pounds in public liability insurance and provide a 10-year guarantee on all new timber window work. When you choose us, you are working with an independent specialist dedicated to maintaining the architectural beauty of South West London and Surrey heritage homes.
