Listed Buildings & Conservation Areas in Swansea

Swansea has many beautiful period properties and listed buildings where standard double glazing cannot be installed. Secondary glazing is the preferred solution in these cases β€” it is fully reversible, non-intrusive, and does not alter the external appearance of the property, making it suitable for listed buildings and conservation areas throughout Swansea.

Secondary glazing recommended by English Heritage can be installed without altering the building's original fabric. Our team will advise on the most appropriate system for your Swansea property and can assist with any local authority liaison if required.

Noise Reduction

Noise Reduction Solutions in Swansea

Many of our customers in Swansea come to us specifically to address noise problems. Whether it's traffic noise, neighbour disturbance, or noise from nearby commercial activity, our secondary glazing systems deliver outstanding acoustic performance β€” up to 80% noise reduction β€” without requiring any changes to your existing windows.

FAQs

Frequently Asked Questions β€” Swansea

How much does secondary glazing cost in Swansea?

+
Secondary glazing in Swansea typically costs between Β£300 and Β£500 per pane, depending on the size of the window, the type of unit, and the glass specification chosen. Bespoke installations for listed buildings or unusual window shapes may cost more. We offer free no-obligation quotes for all properties in Swansea β€” simply send us a photo and dimensions and we can provide an accurate price without visiting.

Do I need planning permission for secondary glazing in Swansea?

+
In most cases, secondary glazing does not require planning permission in Swansea because it is installed internally and does not alter the external appearance of the building. This makes it particularly suitable for properties in conservation areas and listed buildings throughout Swansea. We recommend checking with your local authority if you are unsure.

How long does secondary glazing installation take in Swansea?

+
A typical secondary glazing installation in Swansea takes between half a day and two days depending on the number of windows. Our installations are clean, tidy, and cause minimal disruption. Most installations in Swansea properties are completed in a single visit.

Will secondary glazing damage my existing windows in Swansea?

+
No β€” secondary glazing is installed internally and does not affect your existing windows in any way. It is completely reversible. This is especially important for period properties in Swansea with original timber sash windows, where preserving the existing frames is essential.

Is secondary glazing better than double glazing for noise reduction in Swansea?

+
Yes β€” secondary glazing consistently outperforms double glazing for noise reduction. Because a much larger air gap is possible (150–200mm vs the 16–24mm in a standard double glazed unit), secondary glazing achieves up to 80% noise reduction (54dB). If noise is your primary concern in Swansea, secondary glazing is the superior solution.
