What We Do
Every kind of window has its own intricacies, nuances and unique features, our skill is to bring them out in each project we undertake. Whether it’s the style from Sash to Casement, the period they were first fitted, the stone surround that envelops them... all of them are considered before, during and after the work for a complete window service.
  • New Sash Windows
    Ventrolla have been crafting and replacing wooden sash windows for over 35 years. We operate nationwide and are proud to deliver a 5 star, friendly service to our customers helping them retain the charm and character of their homes.

  • Sash Window Repair
    Sash window repair is part and parcel of owning a period property. For over 35 years, we’ve been helping homeowners restore the beautiful period charm of their sash windows. Our industry-leading sash window repair techniques help to eliminate rattles, draughts, leaks and noise problems, giving your windows a completely new lease of life.

  • Double Glazing
    Double glazed sash windows allow you to keep the traditional charm and beauty of your wooden windows while also benefiting from modern energy performance. We offer two double glazed sash window solutions; replacement slimline timber secondary glazing installed into your existing sash box (window frame) and completely new wooden double glazed windows.

  • Secondary Glazing
    Where double glazing and even triple glazing are common terms that most people are aware of and know that they improve energy efficiency, Secondary glazing is a far less understood. Secondary glazing is a fully independent internal window, fitted on the room side of an existing primary window.

  • Casement Windows
    Casement windows are also known as a side hung windows or as some of our customers refer to it “the one that opens like a door”. If your timber windows are rotten, draughty or unsightly, our repair and restoration service is tailored for you. With over 35 years experience repairing, replacing and draught-proofing timber windows you can trust Ventrolla.

  • Draught Proofing
    Draught-proofing sash windows is one of the most common enquiries we receive. With winter storms raging across Britain battering our homes with 50+ mph winds those of us living in period properties start to wonder if our rattling timber sash windows are going to survive.

  • Window Sill Repair
    Window sill repair is one of our most common call outs. Often bearing the brunt of the British weather, sash window sills need an experienced hand to repair properly. The external window sill (or cill) is one of the main sections of timber to deteriorate as dependent on the elevation, decoration regime and whether the window is operational the sill can absorb rainwater, thus leading to rot setting in.

  • Bay Window Repairs
    An original timber bay window is a sought out feature by many homeowners. It adds both volume and light to a room and gives so many options when it comes to extra seating, reading nooks and other unique touches.

  • Replacement Solid Wood Front Doors
    Period homes are not always plumb straight and it’s these little kinks and deviations from norm that add character, but that also means buying a door off the shelf is not always possible. A Ventrolla door will be measured to the millimetre to ensure a snug fit in your door frame and smooth operation welcoming guests and family for years to come.

Four replacement sash windows with double glazing. No more condensation. The windows look like traditional sash windows. People would not notice that they are double glazed. Excellent service and very clean and tidy joiner. No loud radio either! So all good.

Nice windows. Pleasant staff, good and prompt after sales support if any minor issues arise. Feels very much like dealing with a normal contractor rather than the usual double glazing experience.
