Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

Bathroom Fitting- 20 Jan 2023
We highly recommend Mario & his team. They fitted a new kitchen & bathroom to a really high standard within a short, timeframe. They work hard, are friendly, professional & honest, my neighbour even commented on how considerate they were! Upon first meeting Mario we were impressed by how organised he was. He arrived on time with the description we’d posted on my builder & went through it methodically. We had A LOT of questions! He answered all of them & didn’t rush us. We received a competitive quote within a day as promised. It included everything we discussed & he quickly answered our follow up questions. We wanted an accurate idea of the cost of electrical work & Mario arranged for his electrician to come & inspect/quote before we’d appointed Mario the job. Our kitchen & bathroom is complicated, with lots of difficult angles. Damp, unlevel floor, unlevel windows, a low ceiling were uncovered in the bathroom. Mario did well to identify solutions, giving us expert advice. Pipes were neatly chased into the wall. Underfloor heating & LVT, tiling, grouting & painting all done to a very professional finish. He kept us informed of progress, checked our preferences & was patient when we had supply delays, finding ways to ensure the job finished on time enabling us to move from our temporary accommodation back home in time for Christmas. He promptly fixed some minor issues after the job finished. We highly recommend Mario & would use him again.

Roofing (Flat)- 24 May 2026
Martin came and saw the job promptly. His quote was a little more than another I had had but he made a couple of suggestions and generally demonstrated he knew what he was talking about so I chose him. The job was done quickly and well in a day. It hasn't rained heavily yet but the roof seems perfect. Martin did say that if there were any problems to call him. I am sure everything will be fine but it's nice to have that kind of customer service. Highly recommended!

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.

Extensions- 24 Apr 2021
Kujtim, working with his glazers, created a bespoke porch with a glass roof just as we asked. We were impressed with the finish of the internal plastering and Kujtim was able to come to our rescue one evening when we became locked outside the newly installed porch door. Although the project took longer than was anticipated we are happy with the quality of the finished product.
