Plastering- 30 Jul 2020
We set Mike on to fully plaster our kitchen and the ceiling in an adjoining room. Once we had over come trying to actually get hold of any plaster (covid19) we set a date, Mike kept us up to date through out. He did a brilliant job on smoothing over a very uneven textured ceiling. The kitchen finish was perfect and we couldn't have been happier! He was also great on price. This is our first home and the first time we've ever used a tradesmen. We will definitely be using Mike and his team again in the future.

Plastering- 2 Aug 2025
Friendly and polite, cheap quote. Plastering finish good. Rushed to get finished so cut corners such as plaster not low enough to reach skirting and back boxes not well mounted and already loose - I'll replace with dry lining ones. Basically a lot for me to finish or fix myself.

Extensions- 6 Feb 2021
Steve and his son Mark have built us a lovely , small extension on our converted barn. The work has been completed to an exceptionally high standard using local stone . Steve and Mark were always attentive and sympathetic to “ changes” along the way. All sub contractors involved in the project were equally responsive and sympathetic to the project. I highly recommend Steve as a builder and hope he has the time to do some further work for us in the Spring. My wife and I are happy to answer any further questions.

T.H Builders
Rating: 5 out of 5
Extension Builder in Sleaford
T H Builders specializes in the installation, repair, and maintenance of roof tiles, typically for pitched roofs. I work with a variety of materials, including clay, concrete, and slate tiles, to create durable and weather-resistant roof coverings. My responsibilities include ensuring that tiles are properly aligned, securely fastened, and sealed to prevent leaks and water damage. I also assess and replace damaged tiles, and may install underlayments, battens, and other components to ensure a strong, long-lasting roof structure. For me to do my job properly I need to be Precise and have a good eye for detail as the proper installation of tiles is crucial for the roof’s functionality and aesthetic appeal. Safety is also a key aspect to my job as roof tilers typically work at height and in varying weather conditions.

Carpentry- 16 Mar 2018
Anthony arrived promptly on time, his work was very high standard and nothing was too much trouble. He consulted me first through everything he was doing. He also sourced one of his electrical friends to install my new lighting as my previous light had blown and stopped working. I’d 100% recommend him, he’s even coming back to do some more work for me.
