Hard Flooring- 1 Sep 2026
I WANTED TO LEAVE A MINUS REVIEW BUT THERE IS NONE, THAT IS WHY I HAVE LEFT THE LEAST POSSIBLE SCORE. I PERSONALLY DO NOT THINK THIS GUY CALLED MARCO KNOWS ANYTHING ABOUT BUILDING AT ALL. HE IS A ROGUE BUILDER. HE SAID HE HAS 25 YEARS BUILDING EXPERIENCE, WHICH IS A LIE. I CALLED HIM TO DO MY FLOORING, KITCHEN CABINET, TOILET. PAINTING, FIXING LEAKS. HE RUINED THE WHOLE HOUSE. 8 MONTHS ON, WE ARE STILL REDOING ALL THE WORKS HE DID, HE JUST SPLASHED SILICONE ON THE UPVC TO FIX A LEAK. THE LEAK CAME THROUGH THE CEILING UNTO THE FLOOR CAUSING A BIG FLOOD IN THE HOUSE. HE IS THE MOST UNTIDY BUILDER. HE SAID HE WAS PAINTING, HE SPLASHED PAINT ALL OVER THE HOUSE, HE KEPT SAYING HE WILL TIDY IT UP AT THE END. UP TILL NOW, 8 MONTHS AFTER, I AM CLEARING THE MESS. ALL THE GROUT HE PUT ON THE TILES CAME OFF THE FIRST TIME I MOPPED THE KITCHEN FLOOR. ALL THE TILES HAVE MARKED PAIINT ON THEM AND IT IS EXTREMELY DIFFICULT TO REMOVE THEM BECAUSE THERE IS A LOT OF THEM.
