Enhance the appeal of your home with Wandsworth Sash Windows

London Sash Window CompanyClick here to book your FREE quotationHere at Wandsworth Sash Windows we can supply you with windows that are manufactured and installed to the highest of standards. Whether it is a restoration or replacement of sash windows, from a single window to an entire house, or you are looking for an improvement on the sound proofing of your sash windows, then we believe that we are the right company for you to choose.

We began life solely supplying sash windows in Clapham, but we have since expanded and are now able to supply your home with casement windows, front doors, French doors, bi-folding doors, glass balustrades and splash-backs, plantation shutters and much more. Our customers are not just in London either; we regularly install or repair sash windows throughout the Home Counties and further afield.

You will never be pressurised into buying one of our products. All our prospective customers are seen by a qualified surveyor who will review your requirements and advise you on what options are available. The surveyor will then return to our offices, where an exclusive written quotation is prepared for you by one of our office staff.

We’re a local, family-run business with a staff of fifteen, and we genuinely want to provide you with the best service that we can. We are never pushy, and we have no minimum requirements.

If you only have a single window you wish to be repaired or replaced, then that’s absolutely fine.

Our fitters are expert carpenters who follow traditional techniques, rather than just window fitters.

If you choose to work with us, you can take advantage of the services supplied by our team of highly experienced craftsmen who have worked with all kinds of properties, including those in conservation areas and listed buildings.

We're so delighted with our doors, they look fabulous. Mark & Trevor's hard work and professionalism was second to none. It's not easy having trades in the house with small, boisterous toddlers and everything went so smoothly. Can't say thank you enough

Overall it was a good service - thank you. We found the initial booking process excellent. Our surveyor was friendly and helpful. Our fitting team did a good job overall. We felt that for the amount this job cost us, and the fact that we got all our windows replaced with you, this was definitely good service.
