bespoke New Sash Windows

The finest timber windows are crafted in our workshop. Made to measure and to match the existing style of your home, our timber windows will keep you warm and comfortable while preserving the character and unique charm of your property. 

double Glazed Sash Windows

We have developed a slim double glazed unit designed for period properties. The unit offers modern thermal and acoustic performance and will fit into your existing box frame allowing you to have energy efficient windows without ruining the look of your home. 

draught Proofing for timber Windows

Tested and independently verified to withstand winds upto 71 mph (that’s near hurricane speed) our window draught proofing system effectively keeps the heat in and cold out while also eliminating distracting rattles. 

Wooden Sash Window REPAIR

Where replacement windows are not necessary or allowed due to listed building status, we can restore them to their former glory ensuring smooth opening and closing, rot free and draught-proofed timber windows for many years to come. 

Rotten Window SILL Repair

Often the first part of a timber window to deteriorate, our method of sill repair ensures the strength of the box frame is retained and the sections don’t spread which could lead to more leaks and rot in the future.

casement Window Repair

Side hung casement windows can be replaced and restored in the same fashion as timber sash windows. We also offer a full range of window hardware to choose from in colours to suit any home and style.

IT ALL BEGINS WITH A free, no obligation, SURVEY

Why Choose Us?

Our customers love us and our installers take real pride in their work.

What Can We Do For You

We know that choosing to have new timber windows manufactured and installed is not a decision taken lightly and no doubt you’re doing your due diligence and getting quotes from a number of window companies as you should. Above all things is knowing you can trust the company you choose to be in your home for several days and that’s what we pride ourselves on. Trust. Trust to treat your property as we would want ours treated, trust that we only give you the right unbiased information you need about your renovation project, trust that we will deliver a high quality product and service ever step of the way from initial enquiry through to completion and after care. 

How long Have You been Operating?

We have been replacing and repairing timber windows for over 35 years, starting back in 1982 when our founder Robert Tunicliffe, who work for Ford designing specialist gasket seals, created our unique and patented window draught proofing system. Now Ventrolla is a trusted name and creates high quality bespoke solid timber windows and doors in its workshops across the UK.

What type of windows can work on?

We can work on any type of wooden window, restoring it to its former glory and allowing you to enjoy a warm comfortable and quite home (from outside noise anyway) while retaining the original charm and character that original timber windows embody. We combine 21st century manufacturing techniques using the finest hardwoods and traditional carpentry skills to give you beautiful windows that will improve your kerb appeal and add to the value of your property.

Why are your windows special?

All our new windows have solid through glazing bars that are integral to the strength of the unit. We fit our slim, Krypton filled, double glazing which has been designed for period window installations so it doesn’t look out of place. We also fit our unique draught proofing system that, along with eliminating rattles, can keep at bay winds touching on hurricane speeds. We can install these in your existing box frame or craft an entirely new window frame. Whether it’s our bespoke service or our repair and restoration service you need, you will be left with beautiful authentic windows that have modern levels of energy efficiency and acoustic properties but retain the heritage of your period property.

So when draughts whip round your lounge, rain leaks onto your window seat or the postman averts his eyes from your flaking rotten sills, call Ventrolla and ask for a free, no obligation survey and quote. We don’t do pressure selling and we don’t crowd you. We treat you as we’d want to be treated in our own homes so we’ll give you all the information you need and then leave you alone to make your decision.

How much Does It cost To Refurbish A Window? 

For a standard renovation prices start from £300 per window and usually it takes one installer one day to complete. Times and prices will of course vary depending on the exact nature of the work you require. 

Do You Offer Finance?

We offer a range of flexible finance packages including 0% interest and Buy Now Pay Later to suit any budget.
