About Us

At Aaron Johnson Carpentry we specialise in restoring original sash windows to their former glory through various degrees of refurbishment. All work is carried out by skilled craftsmen and a full, free assessment is made on each window before any work is started. You may think your sash windows are beyond help, but you would be amazed at what we can achieve through a combination of modern techniques such as our resin-based filling system and traditional joinery.

Our company are strong believers in environmental health while carrying out any restoration work, especially in customer’s homes. At Aaron Johnson we use a unique two pronged method of paint removal which eliminates these health hazards - mechanical paint removal and a dust free extraction system. Please see the ‘Dust Extraction’ page for more details.

Aaron Johnson Carpentry & Restoration began with the ethos of restoring the natural beauty of traditional period sash windows, an asset we have in abundance in Britain due to our large remaining Victorian housing stock. Depressed by the ever-increasing glut of PVC plastic windows often fitted to period properties, and the obvious damage to the buildings character, we tried to develop a credible alternative.

We have developed a system of refurbishment whereby an existing sliding sash window could be retained and restored, while at the same time adding modern elements such as draft proofing, sound proofing, modern security and even double glazing, without having to have them replaced. We are now confident that we can provide a range of refurbishment packages that are un paralleled in the industry, at a level of value and competitiveness that others struggle to match.

We are a small company who pride ourselves with still retaining the traditional integrity and methods of joinery, un-changed for hundreds of years. Where we think we can improve on a design or method of construction, we will do so, but always with an eye to the inherent style, longevity and elegance that are synonymous with period joinery. This is always our priority and we take pride in this.
