If your sash windows, frames or sills are in need of some TLC, we can offer varying techniques to solve common problems such as minor or major rot, cord renewal and window rebalancing. At Sash Window Preservation we are market leaders in double glazing existing frames. How? By creating a deeper rebate in the original frame this allows us to fit in a slim double glazed unit. Our special draught excluder is fitted in the meeting rail along with the staff and parting beads. This leads to vast improvements to the thermal performance of the window and heat retention.

We bring years of knowledge, craftsmanship and fine materials to the art of renovating, not to mention creating bespoke sash windows. We pride ourselves on our very friendly and courteous approach with the main priority of meeting the needs and expectations of our clients. We are truly passionate about preserving the heritage of our homes and feel that sash windows play a huge part in the appearance of a period property. We are fully accredited so sit back, relax and be safe in the knowledge your windows are in good hands.

Sash Window Preservation can offer double glazing for your existing sash windows without the costly expense and disruption of replacing the whole sash box and frames. Using a slimlite double glazed unit, we are able to fit this into the existing frame which means the original look of the window is retained. By doing so, the homeowner gains all the thermal and sound benefits without compromising the charm, character or value of their property. Replacing the entire sash window can often lead to new windows that are not entirely in keeping with the period property.

We leave the windows primed ready for decoration but do not carry out any painting. However, we do work closely with a painting company who can supply you with a quote ensuring you are left with a fully finished product. Yes we carry all the relevant insurances that not only protect your home and valuables, but also the general public and our staff. We strongly recommend that you ask any tradesman this before any works are carried out in your home.

When the quote is approved and a 50% deposit is received, we will schedule another surveying appointment to take more detailed measurements. Shortly after we will schedule the work in with you at a convenient time. Our polite teams will ensure the work is carried out with the utmost respect for you and your property ensuring we clean up every evening, removing our shoes and take the greatest care with your property. All windows are left secure overnight, giving you extra peace of mind.

Our draught proofing system is a very effective and popular service. By using a brush system, draughts are virtually eliminated whilst the beauty and aesthetics of the sash window remain the same. English Heritage released findings that. When choosing our draught proof system, sash cords are renewed and windows are balanced to ensure perfectly weighted windows. Alternatively you can email us at info@sashwindowpreservation.co.uk or call 01603 908252 or 01223 927252.

Thoroughly recommend this company, professional, hardworking, dependable and value for money. Just had our sashes renovated and double glazed. The guys were amazing and worked in terrible conditions and late on Friday to get the job done.

These guys are awesome! They are replacing all of our sash windows in our Victorian house in Colchester in phases alongside other work we are having done. So far they have replaced the 3 bay windows in the lounge with double glazed and fully draught proofed windows and furniture and I am thrilled. They are now returning to do the office and upstairs bay as part of phase 2.

Splendid job. Very pleasant workers, very obliging and carried out the work to my complete satisfaction. I can highly recommend Sash Window Preservation.
