★★★★★ – Supremely happy with the work carried out by Mark & Charles to my 200 year old windows. Even when more rot was found than expected did not phase them. Total back to the brick rebuild of one sill and tricky casement with parliament hinges and un-true frame. Quality and courteous service. New ‘fluffy’ seals already greatly reduced road noise from busy street outside…! Would highly recommend. Happy to give referrals. Cheers Lee.
