Fencing- 25 Jul 2020
Overall I am pleased with how the fence looks, the materials look good. Although Mr Little visited the property to give a quote for the works he decided the quote was too low & needed to add a sum of almost £700 extra. This shows unprofessionalism. The work ethic was some of the most bizarre I have ever seen, over 4 days the gentleman from LO Property arrived at different times, getting later throughout the week.They stood around looking at their mobiles much more than I would have liked. The 1st day only 3 concrete posts were removed, I understand much cannot be done on the first day due to deliveries and such but there were 2 of them. There was plenty of work to be getting on with, it felt very unorganised. The 2nd day, half of the concrete post fence was put up, that is much more like the level of work I would come to expect, however this did not last long as on the 3rd day it was yet another doss day. The final day was a complete rush, the job was finished but it was obvious it was rushed. A lot of rubbish was left; a few small tools were left. I wanted to mention the 2 gentlemen that did most of the labour were very polite and professional. Unfortunately I can't say the same for Mr Little, I was not kept updated with the works and the plan of action of each day. He avoided eye contact with me when I did talk with him, when I saw him in the garden mostly he was on his mobile. I just got the feeling he didn't need this job & didn’t want to do it.

Handyman- 18 Sep 2024
I recently had Josh help me with several projects around the house, and I couldn't be more pleased with his service. He installed a wired Ring alarm, changed downlights in multiple rooms, mounted my flat screen TV, and even fitted a lock box. Josh's customer service was excellent from start to finish. He not only helped source the necessary materials but communicated effectively throughout the entire process, ensuring everything went smoothly. He was efficient, tidy, and respectful of my home, making the whole experience stress-free. I'm really glad to have him as a contact and will definitely be using his services again in the future. Highly recommended!

Hard Flooring- 22 Oct 2025
Enea did an incredible job, and we’re beyond happy with the final result. He was very accommodating, helped us choose the right tone of varnish beforehand, and kept us updated throughout the day by sending pictures of his progress (as we were both at work). Enea is trustworthy, and even though we didn’t have the chance to meet him in person, he left the flat securely, taking care of our keys and door. We highly recommend Enea!

Bricklaying- 6 Nov 2017
Very pleased with the job. Daniel and team did exactly what I wanted by rebuilding very damaged garden wall using original bricks that all had to be cleaned. They were polite, hardworking and professional throughout, leaving the site clean and tidy when finished. A few coping stones short so Daniel has offered to look out for more and then return to complete. Will use him in future and happy to recommend to others.

Extensions- 26 Nov 2020
Paul was absolutely great to work with on our project. I would have no hesitations in hiring him and his team again, which we plan to do. He was great as the plans changed, and when unexpected things cropped up he communicated with us really clearly and promptly. The quality of the work is really high, and even as there have been (really) minor snags to deal with after he's been great about these too.
