Plastering- 28 Dec 2021
Lloyd from LGM Builders called to give me a quote to plaster my bedroom walls and ceiling. He was very helpful and friendly. He suggested putting insulation boards on the outside wall to keep the heat in. I also needed one new board on the ceiling. I was told the whole job would be 1 day prep and 2 days work. Lloyd arrived alone and completed all the work in 1 day and asked to be paid. I never expected to have any problems and paid him by bank transfer that evening. I then discovered that the new boards covered my window sill and also didn't allow enough room for the new radiator to be fitted without moving the pipes. Lloyd purchased a new window sill on my behalf and said he would return to fit later in the week. As the plaster dried I noticed lots of indentations and it was quite rough in places. When Lloyd arrived I mentioned the faults in the plaster so that it could be fixed. Lloyd's personality completely changed, his tone was aggressive, which made me feel very vulnerable and uncomfortable in my own home. He said he had done a good job and if I was a painter I would know that the indentations would need filling prior to painting. He then said he wasn't going to waste his time putting the new sill on when he could be working for someone else.

Extensions- 30 Dec 2021
After getting a quote and feeling that James (Kelvin) knew exactly what he was doing, I was pleased I was going to get a bad job done well. After starting 2 months after the date quoted and paying a large amount of money for materials, which weren't delivered as quoted, Kelvin eventually started work (end of October), knocking down existing roofing, and leaving it without any cover for me to move between my house and bathroom, we then had the heavy rain, which he did say was on its way, causing water to get into my house and the bathroom. When he did start, being at work I couldn't see exactly what was going on. These are the problems we are now having after asking Kelvin to leave the job. After moving back door out a little, and external drain now being exposed on the inside of the house, it covered as an eco drain. After placing the cover (which we now know doesn't fit) over the drain, it was concreted up, which is against building regs, leaving any debris in the drain, so after having rain again this has flooded causing water to spread under existing flooring. Bad electrical work - with no name of electrician or cert as requested Life wires being left exposed Bad plastering - which Kelvin admitted he was no good at Roof leaking - no name of roofing company to get back to Floor tiles which he laid v v very badly - loose and able to take up without use of any tooling and not breaking any. I would not advise anybody to take him on as a builder

Bricklaying- 20 Apr 2019
I would just like to let others know that my dream garden is a massive let down. I have been left with unfinished work, sitting water against the house when it rains, loose Indian stone which is dangerous, bricks that are stained. The pillers that are meant to hold the metal gates, one is taller than the other and cannot withstand the weight of the gates. The list goes on and on. Please be aware!

What to ask a Conwy extension builder before hiring?

What qualifications and experience do you have as an extension builder in Conwy?

An extension builder in Conwy should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Conwy extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Conwy?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Conwy extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Do you offer a guarantee for your work? Most Conwy extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
