Absolutely amazing work, very very happy. After being told that all of our windows needed to be completely replaced it was great to have them repaired as good as (or better than) new.

The quality of workmanship was much higher than expected and it’s always entertaining having Isaac around during the day.

I will definitely be referring you to others in the area

Dr. Rot recently replaced all of our door and window glass with double glazing and also repaired all of our rotten timber frames. We are now loving living condensation free and enjoying the residual heat that is retained in the house overnight when we wake on these cold winter mornings. We really wanted a sustainable alternative to replacing all the frames and they were able to retro fit all the double glazing to our existing frames while carrying our the necessary repairs to the damaged frames.
