They attract you with cheaper prices but the final outcome is a disaster.
Avoid! One of the worst services I've ever experienced.
I've contacted them to renovate my back garden: new paving, astroturf and new sleepers. The job was supposed to be completed in 5 days, but it took at the end two full months because they missed most of the appointments (without telling us in advance, so forcing us to stay home every time, even on the weekends), and the few times they showed up, they "worked" for max a couple of hours.
But the worst part is the quality of the job: very poor job, very dirty job, little attention to detail... a nightmare.
Last but not least, when they think they have finished the job, if you complain, they threaten you with very high penalties if you don't pay immediately.
I should have called a lawyer, but I preferred to close the story once and for all.
