Restoration & Refurbishment- 14 Oct 2025
Peter and team did a brilliant job refurbishing our kitchen. He organised building control sign off for knocking down an internal wall. He sourced new glazing for us and designed and built a custom bench seat. He assisted us with ordering the right units for our kitchen. He was great at problem solving along the way e.g. cutting cornice to fit tricky corners. The team were courteous and left our house tidy at the end of each day.

Loft Conversion- 5 May 2017
Artjom and his team have done a wonerful job on our loft conversion and house renovation. We are very pleased at the transformation. Although not the cheapest quote we obtained, they were highly professional, kept the noise down and cleaned up after themselves. We also added several other jobs to our initial quote and they undertook these as requested. It is important to keep a record of everything you ask to be done. They worked very fast and were able to complete everything within 2 months - it helped that our house was empty at the time, so they didn't have to deal with us living there at the same time as the works were being carried out. Overall, I would highly recommend Adam Renovations for any building works you need done to your property.

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!

Bathroom Fitting- 26 Jun 2026
Good value and reliable, but watch the finishing details. Overall, the main tradesman is very friendly and reliable. He turned up exactly on the agreed dates with his assistant. The pricing for the job was fair and competitive.However, the finer details and finishing work were lacking. They rushed to complete the job on a Friday evening, resulting in missed areas in the silicone sealant. Additionally, the boxed-in pipework was tiled crookedly, with one side visibly deeper than the other. When asked to fix this, the tradesman refused, stating it should have been spotted before they left. The assistant can also be a bit careless around walls.He is a good tradesman for the heavy work, but you must be on top of the details. Do not hand over final payment until you have thoroughly checked every single finish.
