I would highly recommend Richard at Sash Repair London. He responded very quickly to my enquiry (even though it was late at night), and kindly fitted the job in the very next day! He was polite and professional. Thanks Richard!Verified reviewerJob location: SW1410 Timber / Wooden Windows Repair

Extremely good and professional expert on sash windows.
Sash Repair London did a wonderful job. Repaired and almost rebuilt two full sash windows in a Georgian house on the same day, inside and outside. Extreme careful planning. Came in the morning and by 3:30pm had already finished. Many thanks. Highly highly recommended!Job location: SW310 Wooden Sash Windows Repair

Sash window redecoration
Richard restored all 5 windows in my flat in Clapham. The bathroom one was really in a poor state. He had all the right tools and experience to know exactly what each needed, including replacing a sill. Richard was reliable and professional. He charges less than the bigger sash window companies. The end results are beautiful.Verified reviewerJob location: SW4
