Yes, painting can be included as part of the renovation process, depending on your area, upon request.

Whenever possible, we use sustainable and ethically sourced materials.

Yes! By repairing and upgrading existing windows instead of replacing them, we reduce waste and preserve resources.

Start times depend on current demand and location. After the initial survey, we’ll provide an estimated start date.

Regular cleaning and occasional care of the draught-proofing system are recommended. Guidance will be provided during handover.

We recommend clearing the area around your windows for access. Our team will handle the rest.

No, for residential customers, our initial survey is free of charge and includes a no-obligation quote.

Costs vary depending on the window’s size, condition, and specific needs. A detailed quote is provided after an initial consultation.

No, our renovation and draught-proofing system enhances energy efficiency without the need for replacement.

The VPSS is our patented draught-proofing system that reduces noise, prevents draughts, and improves energy efficiency while preserving original window character.

While our focus is on period properties, we also provide services for modern homes with timber windows. We are unable to renovate modern softwood windows but we can replace them.

We specialise in the repair, renovation, and draught-proofing of sash windows and casement windows, along with wooden doors and period property joinery.

It differs from office to office dependent on how busy we are and what window work you have chosen, varying from 6 to 14 weeks from order date. Your Surveyor will be able to advise you better on current lead times and our operations team will be able to confirm exact timescales once you place your order.

Yes. We often work on listed properties and those within conservation areas and work closely with conservation and planning officers, English Heritage, Historic England, Historic Scotland and Cadw.

You can get in touch on Freephone 0800 0277 454, email us on info@ventrolla.co.uk, or complete our short enquiry form on our website at www.ventrolla.co.uk. Once we’ve received your enquiry we will be in touch within 2-3 working days to arrange your survey.

Where possible we do all work in situ and take the sashes out from the inside of the property. Because of this, we ask that the rooms we will be working in are cleared, and we will dust sheet all furnishings. If scaffolding is necessary, i.e. there is limited access or for larger commercial projects, then we would always discuss this with you in advance of the order being placed.

It depends on the number of windows you would like us to survey and how long your chat with our Surveyor takes, but we usually say around 40 minutes to an hour.

We specialise in sash windows but we also provide new casement windows, Yorkshire sliders, French doors – anything timber. Please get in touch to discuss your requirements.

We can supply complete new windows, however we don’t sell component parts.

We cover mainland England, Scotland and Wales

Yes, all our staff are Ventrolla trained employees in all our offices throughout the UK and audited to our specification. All our work comes with a Ventrolla 10 year guarantee.

The main way you can combat a condensation problem is to further ventilate your home (i.e. open your windows from time to time). The moisture in your home is caused by heating, bodies etc. and it settles on the nearest cold surface – usually your windows. Double Glazing units will be slightly less cold and therefore you may notice slightly less condensation, however, your home will also be better insulated, thus more moisture may be contained within your home.

For new joinery we use a hardwood, usually Sapele or Accoya, though we can use other woods if specified. Please ask your Surveyor or see your detailed quotation for further information on the recommended materials.

The main complaints we hear about are draughty, rattling windows. Our draught proofing system closes the gap around the sashes; eliminating draughts, rattles and reducing dust ingress and heat loss.

Noise is subjective, but our Secondary Glazing systems and the Ventrolla Perimeter Sealing System (draught proofing) have been independently tested and proven to significantly reduce sound intrusion.

This is not usually necessary, however, if renovation is not a viable option we can supply complete new timber windows that will match the originals.

Yes, all our work is guaranteed for 10 years

This depends entirely upon what type of window you have, however we have developed a service that will more than likely meet your requirements, namely by replacing your existing moving sashes with new, slim double glazed (or even vacuum glazed) replacements.

The time taken will vary depending on the survey result. Typically we work to renovate one window per day, although this can be adjusted to suit your requirements.
