OUR SERVICES

TIMBER SASH WINDOW REPAIR

By fusing classic craftsmanship with modern technology, Ventrolla are at the forefront of the sash window industry. We are uniquely positioned to offer market-leading window care across the UK; from sash window repair and renovation, to draught-proofing and removal.

Our joiners and carpenters are handpicked and trained to exceptional levels, helping our customers improve the look and performance of their sash windows through quality workmanship and incredible service. We pride ourselves on being the custodians of history and champions of the future.

double GLAZED SASH WINDOWS

Preserve the charm of your original sash windows while dramatically improving energy efficiency. You may think that energy efficient double glazing is a modern convenience you have to do without if you want to maintain the authentic charm of your sash windows.

That’s not the case with Ventrolla! We have developed a slim double glazing unit that performs just like a those found in uPVC windows, but retains the original profile and style of your period sash windows.

TIMBER WINDOW DRAUGHT-PROOFING

Sash windows have a 3mm air gap around the sashes to allow the sashes to slide past each other and operate smoothly.

It is this air gap that causes the inherent problems associated with sash windows, such as draughts, rattles, dust ingress and reduced energy efficiency. By installing the Ventrolla Perimeter Sealing System (VPSS) we can draught proof your sash windows and eliminate these problems.

bespoke NEW SASH WINDOWS

Where restoration is not possible we can craft bespoke new timber sash windows that mtch the exisiting style of your windows. The new timber windows are manufactured from either Accoya or treated softwoood and/or hardwood. Accoya has a 50 year manufacturer’s warranty against rot and termite infestation. If you require further information, this can be found at www.accoya.com

The replacement sashes are manufactured using a range of selected traditional ‘through’ glazing bars, and are manufactured and hand finished by our skilled craftsmen in the UK.

ROTTEN WINDOW SILL REPAIR

Unsightly rotten window sills not only negatively affect the kerb appeal of your home but offers the wind and rain easy access to the rest of your timber windows causing further deterioration.

The window sill gets the brunt of the weather and this can, dependent on the elevation, decoration regime and whether the window is operational, result in the sill absorbing rainwater, thus leading to rot setting in.

casement WINDOW REPAIR

Casement windows have the same inherent 3mm gap that sliding sash windows require to operate smoothly and can therefore suffer similar draught problems, unless they have a high-grade sealing system installed.

Ventrolla’s two part process begins with the treatment and renovation of the casement window. The second part involves performance upgrading it by draught proofing the window using our unique Ventrolla Perimeter Sealing System. Using the same materials we use on sliding sash windows ensures the same high quality performance.
