Landscaping- 27 Feb 2021
Gary and his team cut corners from the beginning. A job that was quoted to take 4-6 weeks ended up taking around 14 weeks and even then was not completed by gary and his team due to him walking off the job. They used substandard materials which meant things needed replaced before the job had even finished. Overall the “finishing touches” for the job were absolutely horrendous. A child’s playhouse had nails sticking out of the wood. The nails in the fence had all rusted, the lawn wasn’t laid correct so couldn’t drain. The level on extension was completely wrong. Gary himself was quite rude and Him and his team were extremely unreliable. 100% would not recommend, save your time, money and sanity

Replacement of a conservatory for a larger more eco friendly and useable space to comprise a kitchen, dining and family room. Shea and his excellent team completed the work to a very high standard and I am very happy with the result. In addition he was charming, friendly and efficient as were his colleagues in the trades who completed their various roles in a friendly manner and with an obvious level of expertise and pride in their work. I plan to have Shea and Mountfair Homes back again for my next round of home improvements and cannot speak highly enough of them.
