Our Happy Clients

I have just finished a major condo reno with Mike -- new kitchen, two gutted bathrooms, floors, painting, lighting, etc. It was my third kitchen reno project and this one went very smoothly. Mike was always available, never left the job site to move on to the next one until it was done, and didn't settle until everyone was happy. I even left the country in the middle of the construction and had no qualms that things would be well taken care of in my absence. A very pleasant experience -- and my condo is gorgeous!

Recently had a complete basement reno including a 3 piece bathroom and I couldn't be more satisfied. Job started on time and completed in 3 weeks of non stop work with only minor details remaining which were addressed in a timely fashion. Mike and his subcontractors were always on time, highly skilled and a pleasure to work with. The final cost was exactly as quoted and included extras not in the original price. I got other quotes but after meeting Mike I was confident he was the man for the job and I was right.

Mike Wisniewski and the team at Mike’s Renovations provide outstanding service. Mike is diligent, thorough, attentive to client needs, responsive to concerns, professional and very skilled.  We were struggling to find a way to enclose our top floor bedroom (loft) from the rest of the house without compromising the spacious feel of the room. Mike suggested a glass enclosure. His brilliant idea proved the perfect solution – our room looks awesome.  Mike communicates frequently and reliably. He is honest and has a strong sense of integrity. I cannot recommend highly enough.

I can't say enough good things about Mike and his work ethic. He is punctual, polite and honest. Our kitchen counter looks amazing, the price was right, the workmanship is outstanding and it was completed in a timely fashion. I have no hesitation in recommending him. 

Karen - Toronto

I hired Mike to re-tile my shower enclosure and I couldn't be happier with the job he did. Mike is one of those rare contractors who actually delivers what he promises. He set a deadline for himself and he met that deadline exactly as promised. I would highly recommend Mike for your contracting needs. 

Stephen G. - Toronto

Mike renovated our entire basement (1500 sq feet) and we are extremely happy with the work. Mike has several great qualities that go a long way in the construction industry: 1) He is reliable – If he says he will be there, he will be there. If he can’t make it, he will call and let you know. 2) His timelines are realistic – Mike sets a schedule and tries to adhere to it as much as possible. If something unexpected comes up, he will walk you though the impact to the schedule. 3) He is flexible – I changed my mind several times on a wall in our Home theatre room and Mike adjusted it every time without complaint. 4) He fixes issues during his warranty period – A few small things came up after Mike finished and Mike promptly corrected all of them. 5) His rates are reasonable – For the commitment and reliability, Mike’s rates are very fair.
