Contractor recommendations in Fitchburg Leominster area

[Arian Mustafa]

In the process of purchasing another off market 4-fam and the top floor unit needs a complete overhaul.  Have called a few people I have used in the past for these sort of jobs but wanted to see if the BP community has a recommendation for me.  Looking for a reliable contractor that does the job right the first time.  Have wasted too much time with unreliable contractors and contractors who do shoddy work.  Any recommendations are much appreciated.

This will be a total reno, floors/walls, new kitchen, new bath, fixtures, doors.
