Expert remedial work, crafted with precision
Failed sealed units are one of the most common problems in timber windows and doors: misty or foggy glass, condensation between the panes, draughts and poor thermal performance. Replacing the glazing units is often the quickest and most cost-effective way to restore clarity, insulation and comfort.
At Malbrook Joinery we source and install high-performance replacement glazing units from a highly reputable local company. We can provide you with slimline double or triple-glazed units to suit virtually any existing timber frame — including period sash windows, casements, French doors, conservatories and roof lanterns.
We use only the finest low-E coated glass with warm-edge spacer bars and argon or krypton gas fill. Our slimline units (as little as 10–14 mm overall thickness) allow us to upgrade listed and conservation-area properties without altering the original glazing bars or sightlines, while achieving U-values as low as 0.9 W/m²K.
The entire process is carried out by our specialist team with minimal disruption — ranging between 1 day and a couple of weeks, depending on the complexity. Your existing timber frames and ironmongery remain untouched, yet you gain crystal-clear glass, dramatically improved insulation and the elimination of draughts and condensation for decades to come.
We would be pleased to discuss your requirements. All Malbrook projects are managed through our Reading office, with a single point of contact for customers across the South of England.
