Maintenance Studio
Rating: 4.7 out of 5
Extension Builder in Treorchy
Not your usual construction company: I’m a crafter and visual artist educated in interior design and architecture with a passion in creating beautiful spaces. I like to work myself on smaller projects such as bespoke furniture, small renovations and quality decorations but for bigger projects I can manage a team of traders and craftmans to offer premium property maintenance services, domestic and commercial renovations, loft and extensions, outbuildings etc. Unusual and creative projects all welcome. I have a long experience in bespoke garden buildings of exceptional quality, luxury feeling and stylish design. I design and build your dream!

Carpentry- 15 Jan 2019
The standard of work was abysmal. The photos in the photo gallery must have been taken from someone else's site. Catalogue of errors. Where do I start. - Failed to follow the instructions on boarding the ceiling, instead boxing off part of the room. - Much of the insulation was removed, - The boards were not properly screwed down, leaving unlevelled floor board, with dips and rises in the floor. - Both the flooring and ceiling boards had gaps, which were filled with foam. - The work caused cracks in the ceiling below. - The original fitted loft door was cut. This was cut short. Then repaired by putting another piece of wood on top. The loft door is now two pieces of board stuck together, which is unsightly to look at. -Since the "job" was done the loft door does not stay closed, as the lock was not properly fitted probably due to the loft door not fitting. -The ladder is flimsy, the cheapest on the market. As the loft is high I have been told that the ladder is inadequate. I requested the receipt to return it. The receipt was sent to me after the 30 days that the ladder was purchased. The shop were it was brought refused to take it back as it was outside the refund period. The flooring is so bad it has to be boarded over, which is an additional cost. The plasterer had to screw down boards before he could start plastering.

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

An extension builder in Treorchy 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.

What experience do you have with similar extensions in Treorchy?

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