Ash completed our work in 2022. From the 1st meeting to the last he was an absolute pleasure. Ash and his team completed our 2storey extension, with decking and surrounding glass. This was done within budget and on time. For the amount of work they completed we wasn’t displaced at all. Would 1 million % recommend

Gas Work- 28 Nov 2016
Contacted me promptly. Made an appointment quickly. Arrived on time. Unfortunately the parts I needed are no longer available so this time the fix was unsuccessful but as he was only there for 5 minutes I wasn't charged. Thank you.

Removal of existing conservatory and erection of single storey extension across the full width of back of the house . Including pitched roof with sky lights, patio doors and window to rear and side. Existing rear doors and walls were also removed. Throughout the build I was regularly consulted on progress, any issues were discussed and alternative products sourced ( roof windows) The work was completed to a very high standard, any delays down to weather issues were always discussed .every week I was aware of the plan of work for the following week. Mr Anderton was very professional and reliable throughout the build.
