Conversions - General- 22 Feb 2020
Quoted £500 to remove small kitchen wall (<1m wide), make adjacent wall good, and move light switch. Removed wall, moved switch, and kindly moved fridge. Said he'd return to make wall good. On two occasions I arranged to WFH and he failed to show up or let me know. On multiple occasions he said he might be able to do a day but then didn't confirm. He did come by when we weren't in one day to drop wood off to cover wall gaps. One day I arranged for our dog walker to be in at 1. She waited until 3. I messaged Daniel later to ask what happened. He apparently came at 1.20 and waited for 15 mins. I believe he turned up and our dog walker didn't hear door but it's unlikely he tried to knock multiple times over 15 mins, as she was listening for him. Agreed he would finish work in new year. In Jan again failed to confirm days/times on multiple occasions. Finally agreed noon on a Sat. Failed to show up/respond to messages. Eventually got through to him - said his phone was broken. No explanation re why he didn't show up. Agreed he'd come the next Sat but no show again. No response to message or to later one asking if he planned to finish the job. Received a missed call but nothing further. I've left it a month as hoped he would get in contact. It's clear he has run off with £500, leaving giant holes in wall. I work long hours and weekends are precious. I have no patience for someone who has no respect for my free time, or for fact it's not possible to WFH all the time.

Joinery & Cabinet Making- 30 Jan 2015
Robert is dependable, helpful and generally good to have in the house and on the job. Just one caution, my job was replacing kitchen worktops and he's not a plumber so we had some snags with the sink. Even so. I am a getting a quote from him for another woodworking job.

Extensions- 2 Oct 2024
He did the extension well, brick work is good, rendering on front of house good, terrace and wall with the neighbours good ,toilet under the stairs good, dividing wall in the living room with sliding doors good, kitchen installed good. Fence wall in front of house good brick work wrong bricks but it’s ok. Herringbone parchet wrong with gaps and lifted, rendering on the side of house wrong with marks, the new boiler took 2 months to make it work and the radiators still don’t work. Electrical work bad, after bringing another engineer to check we discovered at the boiler live cut cables that were loose and veri dangerous. Took 4 months to finish job we waited one month for the plumber who either way did a bad job. Laurentiu did not finish the job because of plumbing and rendering, and we ended in bad terms, he left us money to compensate for it. I would recommend him for extensions and any brick work, he needs to improve in pluming, electrical, flooring and rendering.
