Stunning Sash Window Restoration

Sash windows are a fine example of simplicity and elegance, however, like all things, time, neglect, and weather take their toll. Our passion and knowledge for the craft allow us to carefully utilise innovative hardware and modern techniques to restore and repair all aspects of deteriorated sash windows, ensuring a modernised practicality with an original aesthetic. Let our time experienced craftsmen give your sash windows a new lease of life.

The Method

Draught Proofing

The most common complaint we receive for an neglected sash window is the considerable draught and rattle. The gaps between the beading and sashes on one window allow enough air to flow through to fail a modern building’s environmental performance certificate. We tackle this by installing a traditional staff-and-parting bead with a hidden 3mm-brush pile that faces the sashes, as well as the same brush pile along the transoms where the two sashes meet. The constant contact between the pile and the sashes guarantees that the window will have no draught or rattle, as well as offering a premium feel when operating the sashes.

Practical, Quality Hardware

More often than not, a neglected sash window has its hardware and furniture painted over, which especially affects the pulley’s functionality. As we offer flexible packages, subject to survey, we can service any original hardware. However, if required or desired, we can work with closely with our suppliers to offer new, innovative hardware and furniture in a range of styles and finishes, all with a 20-year guarantee. Your cord is replaced as standard, (as the common wax cord is susceptible to snapping) with a cleanable, stretched nylon version that is tested before dispatch from our supplier. This ensures durability year after year and promotes smooth running.

Sill and Rot Repair

The sill is the most important component of any window. Without the correct weather seal, or proper maintenance, the sill will dampen and rot and, in serious cases, compromise the integrity of the frame. Our surveyors thoroughly inspect your sills as well as the window jams. Commonly, we strip back the affected areas to the dry, sound timber, and treat it with our specialist resin, which halts any potential threat of rot resurfacing. Finally, we then splice in new hardwood and seal all cracks and joints to ensure that your window is back to a stable, weather-proof condition for the foreseeable future. In serious cases, we reconstruct entirely new sills and lower boxes.

Expert Glass Solutions

The windows you have are probably decades old, so it’s not surprising to find a few cracks here and there. Here at William Richards, we are proud to offer an array of glazing options to suit your desired end result and budget, including:

Professional Painting Services

If our painting services are required, we strip the frame and sashes of all loose paint, gradually sand the area down to a 180-grit finish, and then apply acrylic primer and undercoats. We then apply the water-based top coats in the finish and colour you request. Our water-based top coat is environmentally sustainable, fast drying, and non-yellowing, leaving your windows with a premium, durable finish without harming the environment.

What Our Customers Think


Frequently Asked Questions

What Advantages Do Sash Windows Offer?
As well as looking great, the properties of sash windows mean that they’re perfect for controlling aeration and the flow of air in your home. These windows are incredibly secure, meaning you’re always protected, even if you prefer to leave the window open.
How Do You Restore My Sash Windows?
With years of experience, we use our skills and knowledge to restore tired windows. We start by carefully dismantling the beading before inspecting the frame and sashes. All broken and rotten materials are removed before we service the pulleys, hardware, and cards. The sashes are weighed and balanced before the frames are primed. Once all of these is done, we re-hang the sashes and re-apply the beading. Everything is tested before we leave.
Can I Replace the Windows of a Listed Property?
The rules around listed properties can be complex, but we’re here to provide the best help and advice to our customers. Usually, you need permission from the local authority to replace windows in listed buildings and we can help you in your correspondence with them. Get in touch now if you need this kind of assistance.
What Is CAD Drawing?
Computer-Aided Design (CAD) drawing is a process in which everything we’re going to do is generated and displayed electronically first. This allows you to see the potential results of our work before we start. As well as reducing errors, it also helps to find the perfect solution for a project.
How Long Does Window Installation Take?
This depends on what needs to be done. If you need permission from a local authority and particular windows, then the timeframe will be longer than standard sash window installation or a residential property. When you first arrange a project with our team, we’ll endeavor to provide an accurate timescale for you.
