Give Your Windows the Maven Treatment
Draught-Sealing & Insulation
We discreetly integrate high-performance brush piles and compression seals into your existing window beads. This eliminates cold draughts and annoying rattles while significantly reducing external street noise, all without altering the historic appearance of your timber frames.
Sash Window Restoration
Don’t struggle with windows that stick or slam. Our specialists replace snapped cords with high-durability waxed cotton and service original pulleys and weights. We rebalance your sashes to ensure they glide open with a single touch and stay exactly where you want them.
Timber & Resin Repair
Before you consider expensive replacements, let us restore your existing wood. We use advanced epoxy resin systems to repair localized rot and stabilize weathered sills. By combining structural repairs with precision draught-proofing, we extend the life of your period windows for decades to come.
