Very nice and warm gentlemen. Efficient service. Didn't give me bad attitude or ridiculous price because I am Asian. Recommended.
Very competative price, quick response and tidied up after. Friendly while professional. Happy to recommend.
Liam & his plumber were successfully able to source a leak and fix the pipe now waiting for a quote to replace the rest of the worn pipes and for all 4 properties to agree to go ahead with the work
Arrived on time work completed two high standards Said what they would do and done it fantastic company
Good job done very tidy excellent work
We had a wall installed in our workspace and couldn’t be happier with the result. The team did an amazing job; everything was done to a really high standard and the finish looks fantastic. Communication with Liam was great from start to finish. He was friendly, professional, and kept us updated throughout the process. Such lovely people to work with. We’d definitely recommend them to anyone looking for quality workmanship and great service!
From the initial meeting to having the work completed there was great communication. The job was completed at a time least impacting on our environment. It was completed to a high standard. There was nothing I would recommend for the team at ALT to do differently. It was a pleasure from start to finish. Currently had some other work looked at from ALT.
Liam got in touch and was out to finish the job exactly when he said and did a brilliant job. Would highly recommend and will use again.
I was contacted by Liam as I had some dampening on my attic wall. Liam was immediate to identity the cause and advise me on what’s needs to be fixed. He is friendly and efficient in his work. I would hire him for my future works.
Liam & Co have been in over the weekend, making our IKEA PAX wardrobes into sleek, fitted wardrobes and they have done an excellent job. They are a great group of guys, worked extremely hard and have done an excellent job. The wardrobes are exactly as imagined. I would recommend ALT Joinery & Building unequivocally and we will use them again in the future for further work.
