Repair Package


HRG Services Ltd provides a bespoke repair package for sash and casement windows throughout Dorset and the neighbouring counties of Hampshire and Wiltshire.

Tailored for each individual window, using our expertise we can restore your original timber windows back to sound wood, without the need to replace them, saving you money and preserving the history and look of your home.

We restore sash windows, casement windows and doors on listed buildings and on some conservation area buildings – where the local authority or client have requested be restored rather than replaced.

Our package includes the use of a specialist resin, favoured by English Heritage for the repair of period timber.  It can also be moulded to different profiles, blending in seamlessly with the existing window and providing a permanent repair.

In addition we can remove decaying and rotten cills and replace them with new hardwood ones where needed


In most cases it is not required, but if necessary we can strip back all existing paint coatings back to bare timber ready to fully establish all rotten areas.

Our stripping equipment uses the latest technology by removing old paint layers using infrared heat.  By using this system old glass can be protected as the infrared will not heat the surface of the glass but simply pass through it.  Also due to the low temperatures work on lead based paints can be done safely.

Should a project not require stripping back then our experienced team will prepare the surrounding surface to the highest of standards ready for our resin systems to be applied.  Our aim is to remove all rotten timbers back to a sound surface, preserving as much of the original woodwork as possible.

As well as removing rotten areas we can also include remove old rotten cills and install new ones and replace profiles and sash pockets where needed using our resin as well as scarfing in new timber sections where needed.

Our repair work is mainly carried out on the project site however if required your windows or doors will be removed and restored at our workshop.  We advise our clients that restoring can be labour-intensive, particularly if the timber is in a state of disrepair.  Sometimes having newly-made items can be a more cost-effective option but we will discuss this with you on-site as to the best way to proceed with your project.

After our resin works are complete your windows and doors will be ready for our restoration and painting package and, if needed, our draught proofing package.

“We recently brought a holiday cottage in Dorset with many lovely original features. The sash windows were a lovely feature but in various states of disrepair and extremely draughty . We ‘googled’ various window companies wanting someone who could address the issues but save the features we loved so much. Many quotes were confusing and advice on double glazing conflicting. David at HRG Services gave us clear reliable, detailed information and a definite time scale to work to. We decided to go with them and we are delighted with the results. From inspection for quoting to completion HRG Services have been professional, informative and reliable and the finished product is outstanding, beyond our expectations. We now have a cosy cottage that has lost none of its charms.”

“David and his team restored 12 very old unusable sash windows for us and we are delighted with the result. We now have lovely windows, in keeping with the house, that still have the original look but with modern glazing and draft proofing. A very friendly and helpful company.”
