Frequently Asked Questions

It depends how much work each windows needs but standard draught proofing without replacing rotten sills, glazing etc starts at approximately £500 per window. For a more accurate quote please call us on 0808 301 9668 to arrange a free no obligation survey.

The time taken will vary depending on the survey result. Typically, we work to a one window per day time scale although this can be adjusted if necessary to suit your requirements.
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 replicas into the original box frames. Find out more here.
Yes, our work is guaranteed for 5 years.
This is not usually necessary, however if renovation is not a viable option we can supply complete new timber windows that will replicate the originals.

Our secondary glazing system and the Ventrolla Perimeter Sealing System (draught proofing) have been independently tested and proven to significantly reduce sound intrusion.

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.
We use a range of timbers, including a fast growing, sustainably sourced super wood called Accoya which comes with a 50-year guarantee and has been specifically designed to withstand the worst of the British weather.
The main way you can combat condensation 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 less condensation, however your home will also be better insulated, thus more moisture may be contained within your home.

Yes, all of our staff are Ventrolla trained employees and audited to our specification.

We have teams throughout the UK, please call us on 0808 301 9668 to speak to your local team or alternatively you can search by postcode.

No, sorry, we are a supply and fit only service. All of our products are unique to us and therefore need to be fitted by Ventrolla trained installers.
We specialise in sash windows but we also renovate, draught proof and manufacture new casement windows, Yorkshire sliders, French doors and anything timber.
It depends on the number of windows you would like us to survey and how long your chat with our surveyor takes, we usually say between 40 minutes to an hour.
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 of any obstructing furniture, we will cover any remaining furniture with dust sheets. If scaffolding is necessary, we will always discuss this with you in advance of the order being placed.

Yes. We do a lot of 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.

Unfortunately, painting is not a service we currently offer, our installers are trained joiners and carpenters and not professional painters. However, we will always prime any exposed wood to protect it from the elements for the short time whilst you organise a painter and decorator. We also provide a detailed step by step guide on how to paint a sash window which has our Sash Removal System installed.

It varies from area to area depending on how busy we are and what window work you require, the lead time normally varies from 6-14 weeks from date of order. 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.

If you’re not able to find the answer to your question, or you’d like further information, please do not hesitate to get in touch with us and we’ll be happy to help.
