Sash Window Consultancy are independent windows, doors and glazing specialists, with expertise in period and listed properties, both residential and commercial.

We manage every aspect of your timber window requirements from sourcing to design, manufacture and fitting, working either directly with property owners or with their agents.

We have a network of reliable, quality suppliers and manufacturers across the UK. As independent consultants, we approach your or your client’s project without any agenda or preconceived ideas.

We carry out an on-site visit to assess the existing windows doors and glazing or provide feedback on any initial proposals by analysing architectural drawings and fine-tuning designs where necessary.

Our refurbishment and renovation specialists repair and reintroduce original features where they may have become lost or damaged, allowing you to replace individual components to maintain the integrity of the building.

Where there is serious decay and no option but to replace entire units we use our specialist manufacturers to produce high quality replacements that sit seamlessly with the retained originals.
