★★★★★

"We had fourteen old wooden windows swapped for flush-sash uPVC in heritage cream, along with a new set of French doors onto the patio. The installers protected every floor with dust sheets, removed each old frame cleanly without a single cracked plaster reveal, and had the whole job weathertight within two and a half days. The change in warmth is extraordinary — we used to wake up to ice on the inside of the glass in January, and now the bedrooms feel like a new build. Outstanding from first survey through to final invoice."
