Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

Plastering- 5 Aug 2019
The job was more than a standard plaster job it was a complete refurbishment of the dining room with the new flooring extending into the hallway. Ionut did an amazing job his attention to detail is first rate I have used quite a few builders over the years and I can honestly say Ionut impressed me the most. He is hardworking, meticulous to detail, tidy and goes above and beyond the job that has been agreed. An example of this was him deciding to hide all loose wiring while he was doing the skirting which has made things much more tidy and also doing new flooring and skirting under the stairs without me asking. He wrapped everything in plastic during the job (radiators, doors, light sockets etc) no plasterer I have used before took that much care in protecting things during plastering which as we know is a very messy job. We will be recommending to all our friends and in the future he will be the first contact if we need any more building work. 100 percent recommend his services and thank you Ionut for the job you have done for us

Bathroom Fitting- 7 Sep 2026
Majid and his team did a fine job of turning 2 old horrid bathrooms into a dream bathroom/laundry! Everything went smoothly, finished to a high standard, and Majid was always on hand or a phone call away to answer any questions we had. It did take longer than anticipated, which was due to us changing our minds on a few things but also abit of time management and staffing issues. All in all a positive experience, Majid was a pleasure to deal with and I would highly recommend. Thanks! (Sorry for not reviewing you sooner!).

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Had a great experience with this team. On time, worked hard, communication was spot on, attention to detail was thorough and overall good value for money. Really pleased with the finished job. The quote was clear and all changes were discussed and agreed as we went through. Would definitely use again and recommend. I could see that they really care about getting it right. That makes all the difference.

Restoration & Refurbishment- 12 Jun 2026
Hired to finish off a complete flat renovation - work mainly consisted of painting, some remedial repair work, light carpentry and a snagging list. Whilst Raj and his guy were great at light repairs, handyman and carpentry work (which is the only reason I’m even rating them with stars), their attention to detail and completion of the snagging list was very poor! Despite having discussions with me to rectify things after I showed him examples, the flat is now left with uneven paint edges, drip marks, uneven grouting, unpainted architraves and sloppy silicone work. Whilst they are good at some things, decorating is definitely not one of them, so it’s a shame and disappointing.
