Open theater and entertainment finished basement

We want to start by saying that Harmony basements has provided is with Great workmenship and quality.

My husband and I are very happy with the quality, commitment and respect that Harmony Basements have shown in our home from day one.

From the first meeting with diego We had all the options we needed and wanted. Harmony provided a good fit and design to suit our desire finish look.
Also the selections and the management was always attentive to our request, with great experience Sasha was able to guide us at their decor studio and finalize with best in class finishes.

Something Very important to us was that Harmony did accommodate all efforts to our needs - Wants and design.

Exelent work from Claudio’s team of managers, scheduling and communication was as expected from a profesional company.
It all worked out efficiently and professionally.

Cstomer service and satisfaction is what matters the most to Harmony's team

There were NO unexpected delays or people not showing up. Everybody was in the house as schedule.

We believe that harmony is a company that does what it takes to do the right job.
before they even started the job All floors hallways handrail all steps and dust protection was set up to protect all aspects of the project.

We would definitely recommend Harmony basements to anyone looking for a respectfully treated and professionally finished basement.

Family fun and relaxation basement

Yen & Trevor Markham Ontario

We are very happy and enjoy our basement very much. Our first meeting and design with Diego went amazingly and smoothly as well as Sasha who helped us with all the selections they have in their decor studio.

The construction and all the contractors were very organized and clean. The work itself was done promptly and smoothly.

Communication was a bit lost a few times but nothing major.

Customer service has been nothing but the best even on any repairs or service maintenance afterwards.

Thank you Harmony Basements for our basement

We would defenetally recommend to others.

Entertainment and work station

Jaimie. Milton

This was our First renovation experience and did not have anything to compare to. How ever our designer Diego has shown all the experience needed to create and accomplish what we had in mind.
In terms of selections it was simple as all the options were available and shown in the decore studio.

The process during construction was conveyed to us in a timely manner although we did had a few days of no progress due to some lead time of materials and inspections, However the project itself turned out amazing.

Our family enjoy it very much.

We have recommended Harmony to others for their quality work done to our basement and customer service provide when needed.

Basement finishing project

I will try to keep this review brief, hoping not to bore the readers. I signed up to finish my basement in early Sep 2018 with Harmony with expected completion in 6-8 weeks. The project finished at the end of Nov 2018.

Overall, I am satisfied with the final job, although few things could have been done better. The basement looks nice.

I am not entirely satisfied with the process that took to get this job done. At one point, I was even thinking of cancelling the work mid-way and taking legal measures, however, I decided to keep working with the company in good faith. It was also encouraging that the owner of the company tried his best to fix the situation.

Harmony sent 3 guys to do the framing and drywall. This soon turned into a horror show (one that you see in reality TV shows sometimes). These guys totally butchered the work and I have detailed pictures and videos to prove this should it be necessary. The framing was not straight. the Ceiling was caving down in the middle. At one point, they almost tried to skip the sound proofing part. I had to get my mom to supervise them round the clock because trust was broken. The plasterer came and could not fix the problem. The errors were so extensive that another framer was sent to literally redo certain parts of the framing again. Of course, unfortunately not everything was redone so I still have to live with less than a perfect job in some areas of the basement. The plumber also made several errors but finally got the work done.

Moving forward, the plasterer was great, he covered much of the mishap that was left behind by the initial framers. The work was further delayed by a number of days where no one showed up. The flooring, bathroom, and kitchen part was done without much problems. The door casings were ordered wrong, but they immediately rectified this and reordered the right ones. I was not too happy with the flow of communication between the office and the project manager but I guess that happens. The project manager was helpful. I had to be very strict with him to ensure that things got done the way that I wanted them and to ensure I got the quality of work that I paid for. He was accommodating and courteous which was very helpful.

The office manager was very helpful with selections. I wasn't happy when some orders were not exactly as they appeared on the website but she adjusted the price accordingly. There were days when my emails weren't replied promptly or in some cases at all, but this could have been due to frustration on their part since the project didn't go as planned and/or I may have been deemed too demanding. In any case, the platform (Buildertrend) through which communication was done and the work was followed was very helpful.

I learned a lot from this experience and here are a few suggestions:
1. do your research, get consultations from many companies before signing up with one.
2. stay highly involved in your project, especially when you pay so much and/or if you plan to live in the place and enjoy it.
3. take some time off work and supervise the important steps ( framing, drywall, and electrical/plumbing work. essentially the steps that are covered and you cannot see later how it was done.
4. keep documents and proof of the work progress, in case things don't go according to plan and you need to take legal action.

Lastly, I still want to thank this company for finishing the job even though it took longer than expected and was painful at times. I have been quite diligent and thoughtful with the score I gave them. I hope that they read this review and use this as a constructive feedback and not be offended in any way.

Hi Jawid, thanks for the honest review.
No excuses, we had the wrong framing and drywalling crew for this job, first and last job for them as they are no longer part of our team after our framing supervisor personally inspected and had to rectify their work.

The schedule was behind by 2 days, as per your project's client portal, it shows that the start date was September 10, Final deficiencies were finished on Nov 12. On Nov 19 we sent a painter just to finish painting a high wall in the main floor that our previous worker couldn't reach. But the basement was finished on the 12th.

We apologize for not giving you the best customer experience Jawid, and we definitely take this as a constructive feedback. You are a very diligent homeowner and we respect that. You decided to go with Harmony after seeing all major competitors and liked us for the following 3 main reasons:
1. Because you knew we are honest.
2. We're also diligent, as we took the time to develop a full 3D render in the initial meeting showing all details of the interiors before you even hired us... we also walked you and your family through the design with our high tech 3D-VR (virtual reality)
3. And the most important, you did a HomeStars Search on major competitors (sorted the score from lowest to highest ratings looking for the negative first and got really scared by the many many complaints they have.. also the "suspiciously removed by author" negative previous reviews)

Harmony Basements is recognized by HomeStars as "the best basement renovation contractor of 2018" for having ZERO negative reviews from previous clients and "No suspiciously removed by author" reviews. We take our work very seriously and customer satisfaction is our highest priority, when head office received your complaint in November, the project manager on charge got into probation, it's evident that the supervision for this project wasn't done according to Harmony' standards; in December we had to let him go because of the frustration we all experienced with this project.

Harmony's project management application shows before, during and after pictures of all basements... and yours looks espectacular!

Our clients shouldn't be supervising our work themselves; Harmony's one stop solution has in-house project & quality control managers for every job. As you experienced, we do everything by the book with building permits and have a complete workforce of desigers, architects/engineers and in-house trades.

All clients need to be involved in the initial rough-ins for approvals of final chalk-line pre-framing layout, outlets/switches/fixtures placement, etc. 2-3 days. We do this to avoid changes that could delay the project.

Thank you for your business. Enjoy the basement!

Thanks for the review. The city of Toronto sometimes put our schedule behind. Finishing basements the right way like Harmony does, eg.. with proper R20 insulation on exterior foundation walls, all required inspections, etc... takes time! We're glad to hear that you are happy. Thanks again and enjoy the new basement!

We understand Contruction is a hard thing to do with limited time and space , However the overall results have been ntothing but satisfying.

Every one on their team from the sales design to the project manager assigned very professional and very knowledgeable.
Everyone did whatever needed to accomplish the beautiful finish Gym and basement we enjoy today , they have turned an empty space to one of a kind play / exercise and relax area.

We would defenetly recommend Harmony Basements to anyone planning to finish a basements professionally.

We're excited about this new years' open-house showcase events where homeowners interested in renovating their basement will be able to see our work in person on the weekends, they will also experience the "3D Virtual Reality Basement Design" we created together with the client in the initial consultation before they hire us, a unique experience found nowhere else!
Thank you for choosing Harmony Basements!

Legal second suit basement

Harmony basements fantastic experience.

I am very happy with the quality, commitment and outcome result that Harmony Basements have shown in my home.
I now know this is a company stands for what they promise and believe. Harmony has added value to my investment with great finishing.
From the initial sales meeting and decor to the management system they use it was noticeable that they have the knowledge to do good work.
I was never kept in the dark when the quote was given to me and there was no hidden fees or added cost.

Over all Great work and because of that I would definitely recommend Harmony basements for a professionally finished basement.

Dear Orleen, thank you so much for taking the time to write about us. Working with clients like you is always a pleasure and an amazing experience. When we meet you at the National Home Show back in March, we knew that was just the beginning of a long-term business-relationship. I saw the progress: before demo, rough ins and finished product in the scanned 3D-Virtual-Tour that was uploaded to the Harmony Building Project Management System / client portal, and that soon will be uploaded into our case-study portfolio web-page: https://harmonybasements.ca/our-work/ -- and let me tell you that the transformation looks incredible, the purple closed cell R20 spray foam insulation looks neat, the 3 new Egress Windows, it's just fantastic. We are glad to know that you are happy with the legal 2 bedroom basement apartment. As a continued service we are just a phone call away if you need our assistance. Thank you again for your business!
