They came to fix a leak in my conservatory after removing tiles they said what they had planned would not work. They reckoned the leak was coming from the roof on the house and said they do conservatories not roof repairs. They put tiles back on and charged me £160 for their trouble.

Excellent communication. Great team of friendly helpful people. Cleaned up, left spotless plus some extra rubbish for me.

Great work by great staff. They turned up as promised and a two day job got done in one day as we where on holiday the next day so they worked there socks off. The work carried out was excellent cannot fault it tidy up after they had finished at 7 30 at night. If you want the best get this company in to do the job.
We were impressed with the work done. Nothing was too much trouble. Estimate, Survey and final work and completion very smooth and no fuss. Just a good job, well done.

Window Warranty excellent. No other companies replied.
I paid a £500 deposit for work to be done however I was messed about with several promises of people to come and survey etc that I cancelled and was told they would send me the money by cheque and it would take 3 weeks. I have been waiting 8 weeks and have contacted them but there is no sign of my refund. I have informed them I am taking them to the small claims court and that is my next move. So I am not impressed.

No close investigation of the problem. Identified as a conservatory roof problem, unlike above who identified a felt problem on the house roof. Very expensive quote. Asked for written confirmation which never materialised.
Very quick to get back to me – just arranging an appointment for a suitable time

Very quick after initial contact. We had 3 cancelled dates before they finally did the work. The work was carried out speedily and to our satisfaction. The guys Phil and Quinn were excellent workers, clean and tidy.

The gentleman that contacted me advised he did not deal with cast iron gutters. He said he could send one of his agents but unlikely they could help

We were given a 2 hour slot to come and look at the issue but the person never showed up. I was assured that if it would be any different they would call to let me know, but i received no contact. Still haven't.
I only wanted repairs but was persuaded i should have new roof panels which i was quoted for. measurements were taken involving only one man doing a two man job thus taking most of the day. it was then decided that the roof struts weren't strong enough to take the new panels. then many weeks of no contact from them ensued. i received a letter that was sent to all customers asking us to bear with them due to the pandemic. i understand that, of course, it has caused many problems. however, i had to contact them several times and was fobbed off again and again. about 2 weeks ago i was informed that someone would call to make an apt. he didn't call. a few days ago I asked for my £1,000 deposit back which I paid to them on 20th May this year. Finally, I received a call saying they would have to requote. This was ignoring the fact that i had asked for my money back. I said I want my money back and he said he would refer it to the accounts dept. No apology whatsoever. this has been a very bad experience. it remains to be seen whether i will see my money again
