A few reviews for this pro...



I looked up in Angie's list and called Mazzi contractors. He was very nice and drove by the place although it was a weekend. He gave me an estimate of $700. He could not start the job due to bad weather. In the meantime I contacted another company, APM Masonry & Construction. They came, inspected and gave me an estimate of $6800. Mazzi did the job fo $700. They are very honest and professional people. I will use them again and recommend to anyone.

We were looking for a contractor to remodel our 150 sq. ft. bathroom and closet. We called their company to give us a quote. Someone came out and looked at the area and said he would send a quote. A few days later he called back and said he would like to have his partner look at the job. I agreed and scheduled another time to meet. They came over again and looked at the project. They also asked me what my budget was several times. I don't feel comfortable telling anyone what my budget is until after we come to terms. I expect to tell a contractor what I'm looking for and show them the area. They should then give me a quote for what they think it would cost to do they job. During the last meeting they mentioned that it was probably going to be a 35k job. Since I've recieved 3 other quotes I knew that was very high. They seemed very discouraged when I told them that 35k was way out of my budget. Over 6 weeks have passed and they never even bothered to send a quote. I wasted two appointments with them that each took over 40 minutes. I found them to be unprofessional and do not respect other people's time. I recommend calling someone else. Updated 7/2/15. In response to Mazzi Contractors message below I'd like to update my review. Their message reinforces what I was complaining about. It took them two separate meetings for them to finally get me to tell them my budget. They would not stop pressuring me for a specific number. Any contractor that can't provide a quote without knowing you're budget is not trust worthy. They also admit never sending a quote. So they decided to waste my time coming to my house twice and then decided to never send a quote or even tell me why. They never told me that they couldn't fit our budget. They just never responded. Is this the type of company you want doing a 35K remodel? They obviously have no idea how to treat people or customers. We had our bathroom remodel done to our satisfaction for $13,500. This included everything we described to Mazzi Contractors. Their price was $35,000 for a 150 sq. ft bathroom and a 40 sq. ft. closet. They are over priced contractors preying on uniformed consumers. My last contractor did mess up my remodel 5 years ago but he came highly recommended and wasn't cheap. He did bad work but how would I know that until after the job was done. Sorry Mazzi Contractors but your unprofessional response shows how bad you really are and reinforces our decision to stay clear of your company. I'm glad you never sent the quote I may have been scared into signing it in fear of having another bad job done. Fortunately for me I got many quotes and found that your ballpark number was about $20,000 to high. In fact your "off the cuff" quote was $18,000 higher that the highest quote we received. If you want an over priced remodel or if you just want to waste your time contract Mazzi Contractors.

Service Provider Response

After our second meeting with the customer he indicated he wished to do the renovation for "around 15k". Unfortunately Mazzi Contractors could not meet this price and I indicated this to the customer. There was no reason to send an estimate when we were not interested in working with this customer. Customer also fails to mention the reason he was renovating the bathroom was because it was falling apart after just five years because of a cheap renovation he had done. Mazzi Contractors has 35 years experience and the reason our renovations don't fall apart is because we employ highly skilled plumbers, electricians, carpenters, tile installer, granite fabricators, and painters...all needed for this job. If we had renovated this bathroom the first time the customer would not be renovating all over again 5 years later. This should be a lesson to get what you pay for.

I contacted several roofers in the area and on Angie's List for estimates. It just so happened that I had received a promotional flyer in the mail from Mazzi contractors offering services at reduced prices as part of an area advertising campaign. Jim Ledo came to my house and looked at the roof. He was professional and courteous and gave an honest assessment of the job. The roof was started by Val and I was highly impressed by his punctuality and work ethic. He worked all day, mostly by himself, stopping only for lunch. He was neat and careful and seemed to take pride in his work. At the end of each day, he cleaned up everything and you never knew he had been here. He worked by himself three straight days and on the fourth day, Mike brought a crew to finish the job in a timely manner. Mike then stopped in to assess everything. I actually had him look at another small job for an estimate. The roof looks amazing and I would highly recommend and consider Mazzi Contractors for future work. Thank you, Jim and Mike for making this experience a pleasant one.

Service Provider Response

We were NEVER contacted by [member name removed] via company email or by phone. Due to a computer glitch we were unable to access her request thru Angie's list to schedule an estimate to repair her gutter on her porch. So it's a bit confusing as to why this customer would rate Mazzi Contractors so poorly when we NEVER even had contact with her. Very disappointed how some people use Angie's list to bash a company who never even did work for them. Thankfully we NEVER did do work for this homeowner because some customers you just can't please....even when you NEVER worked on their home. Sincerely, Jim Lido, President of Mazzi Contractors.

I was looking to have some work done and I looked at the recommendation after Mazzi Contractors gave me the quote. There was nothing about them either way it was more of a pricing issue. I found someone that was less expensive. I wouldn't say they were expensive. There is nothing the matter with them like they were overly expensive. It is just that there was somebody else that was less expensive. They are really nice people. They came out when they said they would.

They were good. The guy who did the work did an excellent work. The only thing is that they didn’t clean up as well as I would have like. That was the only downside. We got this new product. It’s not aluminum siding, its vinyl siding and it’s very attractive and they did very nice work. I would have liked a better price. They came back and did kind of a punch list that we wanted.

A week later all they gave me was an estimate with no plans. I was only interested in the plan and not in his labor services and they weren’t happy about that. Essentially, I was charged $50 for a quote. I asked for a refund from Angie’s List and contacted the service provider regarding my concerns and they did respond.

I ordered the Big Deal on 5/7 and had a reply by 5/8 that they would put me on the schedule. I had not heard anything from them, nor seen any work, so I contacted them on 5/30 to find out when they would be out. The next day Jim replied that the work had been done on 5/9. I went outside and looked at the house and could find no evidence of new caulking except for a couple of clumps of clear around the front door. I responded that I was not happy at all. Jim replied immediately that he would make things right and had a different crew out the next day. The work that was completed on June 1 was well done.

My husband & I called at least 4 contractors for roofing estimates. Our roof was damaged from the storm last year. It took awhile with our insurance agency to complete their roof inspection and release a check. Once, the insurance check was issued we were able to move forward in contacting roofing companies to get estimates for a new roof. I spoke with neighbors and visited roofing companies from home shows. There was a range in prices but it was worth the time in investigating the roofing companies and checking up on references. We made a decision to go with Mazzi contractors due to longevity of their business, and the quality of their work from references we contacted. What surprised me most was the speed in getting this job done. It was completed in 3 full days, the roof and gutters. This was amazing to us because a neighbor down the street had roofing work done by a different roofing company that took 3 months. The roofers from Mazzi contractors that came to my home were polite and efficient. There was no loud music playing from the trucks.There were quiet. When the job was completed the debris that fell was cleaned up swiftly. A metal sweeper was passed over our lawn to pick up any loose nails. The roof & gutters look beautiful ! It is almost too good to believe that it went this easy. I hope any new future home improvement projects we may encounter will go as smoothly. I highly recommend MAZZI Contractors. The pricing was very competitive. I am a believer in you get what you pay for. Plus, go with someone who knows the business well. Hope this helps someone.

The were very responsive and responded to my inquiry fairly quickly. They were very courteous and very professional. The contractor who came out had some good ideas in addition to the original things I had asked him about. He did not get back to me as punctually as he said he would. He said he would get back to me that night with an estimate and two days later he still had not gotten back to me. I didn't know if there was a problem with the email but it definitely had an impact on me in the decision making. I would still consider using them.

I called the Monday after I signed up for the Big Deal. The service provider connected me with the maintenance specialist Jim. He and I talked on the phone and he scheduled me for a visit. He told me that I didn't need to be home for the maintenance visit. He asked me if there were any areas that needed particular scrutiny and I gave some areas that may need attention - back door and bay window. He said that he had a ladder that would allow him to reach up to the sidings above ground level to inspect. He said that he would nail down any loose sidings if found. I came home and saw that caulking were applied in places where it would help to prevent water seepage around the windows. I cannot attest to other places where work was done since I cannot climb up. Meant to call back to ask but I have not yet gotten time to. I feel that the overall experience was good and fair service rendered.

We recently had our windows and sliding glass doors installed by Mazzi Contractors. We were highly impressed and satisfied with the professionalism and craftsmanship that was done in our home. I found Mazzi Contractor's men to be very hard workers and dedicated to the job. They were punctual, considerate, and cautious with their equipment in our yard. Most importantly I admired their attitude and concern of our approval. We were extremely pleased with our new windows and sliding glass doors. Everything was done to our satisfaction! I highly recommend Mazzi Contractors for any work needed in your home. We are considering a new roof soon and Mazzi Contractor will definitely be our choice.

I signed up for their big deal coupon for $299 for a new installed attic fan. After over a week of trying to schedule a date with them, I get an email saying that they messed up and should have put in the coupon that this did not include any electrical work. This is a huge detail to leave out of a big deal coupon. I still haven't gotten my money back and I'm really upset that they didn't try to make this right for a potential customer. Not happy at all.

Description of Work
The contractor offered a special deal for an exterior home maintenance package which I signed up for. He called me a few days later to schedule an appointment. The workman arrived an hour earlier than expected but on the pre-arranged day. He worked for two hours as arranged and, as far as I can tell, he did what was expected of him - that is - he calked around doors and windows and secured some sagging siding. I was pleased with his work.

Came when I was not home without an appointment. They had advised me that I would be scheduled for the week of May 13th. Did a terrible job. It looks like a child did it. I would invite any member of Angie's list to see it before committing to any work by this contractor. Again the caulking looks terrible and should now be removed and redone.

Service Provider Response

An appointment was scheduled on 5-6-13 with the customer who gave us a detailed discription of what she wanted caulked. The problem with her request is that she wanted a $99 coupon good for caulking/siding repair to to be used to address a much more serious issue involving her delapidated porch roof over a garage. We used four tubes of caulk to fill in large gaps throughout her back porch area per her request. The Customer wanted more for her $99 and we even volunteered to return but were not given the opportunity before such an unfair review was submitted. Our record speaks for itself and customer satisfaction is our number one goal.


Min Z.

There was some miscommunication with the provider and his big deal. First he took awhile for the contractor to get back to me. And it took awhile for them to just tell me no they could not honor the promo due to their error of wording. It sounded to me like it would of been a new attic fan installed but come to find out its replacing an existing one.

We apologized to the customer as Mazzi Contractors are not lisenced electricians needed to install the attic fan requested. She was told how to get a complete refund for the coupon purchased.



This was a very pleasant process. Jim was great to work with giving us the estimate and helping shape our vision. Joe helped to explain which of our ambitious plans were reality based on our budget and some structural issues. They ran into some delays in getting permits thanks to my township (and clearly of no fault of Mazzi), but started when they said they would. Once they started, the cleanliness of the site was great. We joked that it was cleaner than we left the house normally. Howard was a machine. He worked hard, made sure his guys did the same, and was very respectful to us. In a contractor, all I ask is for hard work and honesty. He was an A+ in both. The framing was done quickly, as was the installation of the heating and insulation. The drywall guys worked on a Saturday since there was a delay getting them during the week, and their pace was amazing. Howard installed our doors and gave us some insight on the best product and fit for our home. He wasn't motivated by money and always seemed to do things with our best interest in mind. The electrician was another great worker - he had done a similar renovation on his own home, and the common project was a benefit since he incorporated certain things (separate switches for lighting, dimmers, tamper proof outlets) that made sense for our family. He was also kept an incredibly clean worksite. I was less impressed with the siding guy. He worked at a reasonable pace, but we found some nails and debris in the yard. Not small ones either - one nail was probably 12 inches long. He also took a week vacation in the middle and we did not know where he was. Seems like more of a miscommunication than anything else. The shutters also took a long time before installation. This may have just been ordered with others but nonetheless the exterior renovation took a bit longer than expected. The quality of his work was good, and overall these are pretty minor things. Now that the exterior is complete, it really looks great. The painter was satisfactory. Seemed to work short days and there were some longer gaps between days he came. I may have had unrealistic expectations, but a job that seemed like it could be done in 3-4 days took well over a week. His quality was ok, but he seemed to miss a few things (the trim outside our front door, there is some sloppy work underneath our built in cabinet and around our sink). Again - the quality is fine, but not necessarily at the same standard as the rest of the house. We'll have a few touch ups to do ourself. All in all, we are extremely please with the project. Outside of some minor delays - which are the nature of the business - we got what we were promised and are living in a comfortable room with our 7 month old son. We will use them for some future work - roof in particular in a few years. These are guys I trusted in my home. When our financing became a major issue, they worked with us and were flexible even though they did not need to be. Very glad we hired Mazzi Contractors.
