Jess painted my hall way and put laminate flooring in my lounge. He was prompt and reliable, I was impressed with the how quickly and professionally it was done, he was extremely tidy and put my sofa back so I could still access my lounge in the evenings whilst the work was going on. He was professional at all times, and even helped me with the colors, I would highly recommend him.

Extensions- 3 Oct 2022
I gave him the opportunity as I was desperate to find someone fast,and didn’t have much success on here.Soon as he accepted,he was already asking for cash beforehand to get materials.I thought you know what,his company details are online,what can go wrong so I did.As his team started the job, they told me I needed to have 2 fences erected as they were badly damaged and deteriorating.I thought heck,why not,might aswell do it now so I gave him again, the opportunity to make some extra business with us.Again,was asked for some pre payment to get the materials,all in cash.All was finished within 2days of the weekend.Fence looked fine,but the roof just looked like a cowboy job.I didn’t complain,as it was done fast,with all the stress with opening a new business,it was one less headache out of the way.After 1 day of rain,the roof was already leaking,like absolutely everywhere.Called him, and he got someone to come by a few days after to fill in more silicone.(Very suspect job again).I thought fine, aslong he’s responding and trying to fix the situation.Fast forward few days later, bearing in mind the shop isn’t open and I’m not always there when it’s raining,it rained again and it was leaking in some areas again.Whatsapped him which is how we normally communicated,called him,read my messages but no reply. Now he has blocked me.Seriously, how he knows I’m opening a business soon this is how he wants to treat his customers. Simply give me back my money or fix the problem, simple!

We recently completed a first and second floor renovation alongside an 5x6m extension of our 1930s property with Maxcontractorsint.ltd , and we couldn’t be happier with the results. From start to finish, they have been absolutely fantastic. The attention to detail and the quality of workmanship throughout the project has been exceptional. Matt and his team are incredible, they worked efficiently, kept work on track, and made sure we were updated and involved at every stage. Their skills, ideas, and collaborative approach truly brought the whole project together. Communication throughout the project was good, and the team provided great pre and post project support. Matt was very detail-oriented, offered inspiration during site visits, and was supportive of our requests along the way. We’re so happy with the end result and would absolutely recommend Maxcontractorsint.ltd for any project.

Latest review:
Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Earlier this year, I was looking for a builder to erect a side extension and was given the details of Colin Richardson. He came highly recommended by various other people. He always arrived with a smile on his face and always at the time specified. The day to day work area was always cleaned at the end or the day, leaving it nice and tidy. I am very pleased with the work both Colin and Michael did and I would recommend them ti anyone looking for building work to be done.
