George Bell came to work on some damp related issues in my flat in feb. since having completed the works the problems which first occurred have turned worse and George has been unwilling to get back in contact with me, despite chasing him for 5 months which only reaffirms that the job was poorly undertaken. The company main reception also seems to be a virtual reception so you can never speak with anyone helpful

We chose Timber Box Sash Windows to double glaze our sash windows after Andrew came out and surveyed, then followed up with a really decent quote. We got the work done in two phases and both times were really hassle free with the joiners turning up on time and getting on with the job. They were a real pleasure whilst they were here. Very polite and friendly. It’s good to have the same person that surveyed the job actually carry out the work as well, makes for a really smooth process.

Amazing service From Alen and his team. His quote beat the competition by far, but without any compromise on the windows. We were only planning to have new wooden double glazed windows for the front of the house, but were actually able to have new windows for the whole house. Alen also made suggestions which we had not thought about. He said we would have beautiful new windows and he has delivered. Clean, polite and kept informed throughout the process. Wholeheartedly recommended.

Only two companies expressed an interest in my exterior decorating job, the first being situated +/- 50 miles away which, logistically seemed less than ideal and certainly not local. The second, Haus Company, was closer to my location and was awarded the job. The team of two, Robbie and Paddy, worked hard during a torrid heatwave and completed the work in 5 days as planned. The finished work more than lived up to my expectations in terms of quality and I'm happy to recommend Haus Company.

There was a watermark around the inside of my Velux window which suggested a slow leak. Danny responded and agreed to come and look at it, he kept me informed about the day and time. He wasn’t able to do the repair on the day but provided me with a reasonable quote. He arrived to complete the work and again kept me informed about a change in the time. The work was done more quickly than he had anticipated and the price was revised down. A nice polite individual who I will have no hesitation in using again.
