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.

We have used Skeffington Properties for the last two jobs on our house. The first was resealing of the conservatory and second was sorting our porch roof out to stop a continuous drip that started last week. Both jobs completed promptly after our requests and tidied after themselves. Thanks

Dafydd and his team have fitted a new welsh slate roof on part of our farmhouse, built a rear retaining wall, fitted surface water drainage to the rear of the building and rendered one of the two gable end walls in lime mortar. The jobs have been carried out to a very good standard and the workmen have been excellent in both carrying out the work and looking after the property whilst working there. They still have one gable wall to complete but due to weather conditions and the use of lime mortar this will be down when the weather improves. Whenever I have discussed any part of the work they have been quick to react positively. Overall really satisfied with the work and will be hiring them to fit new concrete floors inside the house and Dafydd has already organised a visit from a heating engineer to give a quote on central heating. One final point, the financial cost of the work completed has come in just as the initial quote stated which was very welcoming given scare stories you hear of every increasing bills. No such problem on this job and overall very pleased with Dafydd Lloyd's work. In my experience there a good friendly professional firm to hire.

What to ask a Dolwyddelan extension builder before hiring?

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

An extension builder in Dolwyddelan 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 Dolwyddelan 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 Dolwyddelan?

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 Dolwyddelan extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Dolwyddelan 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.
