with Mario Tardif &  CWI - Custom Wallboard Interiors.


Here is what some of them have to say:




"We originally hired Mario to do the drywall in the basement which he did like an artist (on speed) but then kept him on to do basically everything except electrical and plumbing. (Spackle ceiling, paint, trim, door installs and flooring) His workmanship is second to none and his prices are unbelievably low. He saved us a bundle on the project and we are delighted in his work. Thanks Mario!

"Mario was courteous, punctual, on budget, and exceeded my expectations in his ability to repair my drywall and tile my kitchen backsplash. He took care of my home and is someone who I would highly recommend."

Stephanie Schader

"Mario Tardiff of Custom Wallboard Interiors did a great job of refurbishing our open concept ceiling after a disastrous attempt by another company to repair a short cosmetic crack. What should have been a minor job turned out to be a major project. Mario worked on this messy job day after day during the heat of August. We are very pleased with the outcome and would not hesitate to hire him again. We highly recommend Mario of CWI."

Sharon & Jack Rogers.

Mario did an amazing job repairing a ceiling crack and then re-texturing the area. 

Mario has also done tile flooring and tile backsplash for a family member. The end result was beautiful!

I would not hesitate to have him do work for us in the future. He is extremely professional and reliable.

Val Palmer

"Recently we had renovations completed in one bathroom, the kitchen and main entrance hallway. 

The bathroom was freshly painted, the floor and area behind the vanity and toilet were tiled and a new textured ceiling was installed.  All of this work was professionally completed by Mario.  In addition, Mario was happy to help install a new light fixture over the bathroom vanity. 

In the kitchen and hallway entrance the old flooring was covered in lino.  This was all replaced with tile flooring.  Mario took extreme care to lay the tiles with precision and to ensure that the pattern in the tile was most esthetically pleasing.  Mario also installed all the kitchen backsplash tile as well as the new oak baseboards in the kitchen eating area. 

The existing “sunshine kitchen” light box was removed and pot lights were installed.  This made it necessary to have the entire kitchen ceiling re-textured.  Mario completed the ceiling work and it looks amazing! 

Throughout all the renovations Mario was always punctual, professional and extremely knowledgeable.  His suggestions and recommendations were greatly appreciated.

 Thank you Mario for doing an excellent job in our home!"

"Dear Mario:

Thank you for all your work. Our basement looks amazing and we are so pleased.

We will recommend your work highly.

Thank you again."

Brent and Tasha Carmichael - Kelowna, BC

"We feel very fortunate to have found Mario Tardif and his Custom Wallboard Interiors on Castanet. After numerous quotes from numerous contractors to finish our basement in Wilden, Mario's was, by far, the most reasonable (and he stayed on budget!). While it may take a little longer being a one man show, his work was meticulous. We originally hired him to just do the framing/vapor barrier/drywall but we wisely kept him on for the textured ceiling, primer/paint, door installation, laminate floor install and complete trim/baseboard finishing. All of his work was outstanding and we are extremely pleased! Thank you Mario!!"

Andy and Shizuka Giffin - Kelowna, BC


Thank you so much for the work you did.  I am very happy with the results!  It was such a pleasure working with you.  I have been waiting for over four years to have this work done, and you were able to do it for me in just a few days!

Please add me to your list of references.

Merci encore une fois!

Bien cordialement,"

Tania Rutt - Kelowna, BC

Hi Mario,

You are welcome to use my name for your reference.

I wish you all the best,"

To Whom It May Concern,

My name is Laurel Worobetz and I am the Indoor Maintenance Director for the Okanagan Housing Co-operative in Kelowna, B.C. Our co-operative consists of 58 townhouse style homes run by a volunteer Board of Directors. As the Indoor Maintenance Director I am responsible for planning renovations as well as repairs to the members units. For this process I am also responsible for obtaining quotes to have the necessary work completed. Through this process we found Mario Tardif (CWI - Custom Wallboard Interiors), and chose him (and continue to choose him) to do our renovations and repairs and I would like to take the opportunity to describe our experience with him.

Business - Mario is not only a professional tradesman; the way in which he runs his company is very impressive. From the first time I met him I have consistently seen that he pays a great deal of attention to detail, provides thorough quotes, is always on time and prepared, is reliable and responsible, is easy to get hold of, and responds to communication in a timely manner. It is obvious that he truly cares about his customers and his business practices show this.

Pricing - It is our co-operative’s prerogative to make our renovations an investment. We know the old saying  “you get what you pay for”. When comparing Mario’s quote against 4 others we found that although he wasn’t the cheapest, he wasn’t the most expensive and was still competitive. We noticed he asked the most questions and felt that his quote was the most thorough. He was the only one out of the 5 companies that submitted a professional list of references and a description/background on his company. This allowed us to see pictures of his work and contact his references. We chose him based on these factors and are happy with our investments.

Character - Mario is a pleasure to deal with. His demeanor is polite, courteous and professional. Also, the members who have had him do work in their unit (including myself) have all found no concern or worry with leaving him alone in their homes, as he is very trustworthy. He is refreshingly personable and honest in an industry sometimes associated with crassness and/or “slimy salesman” types.

Workmanship - Mario’s work is impeccable. Any renovation is stressful and can be hectic but Mario’s demeanor and skills allow the projects to go effortlessly and seamlessly.  Listed below are some of the jobs Mario has completed:
- Full bathroom renovations ( including minor mold cleaning )
- Ceiling repairs which include matching textures
- Replacing sections of drywall
- Countertop installations
We have seen through all of the completed jobs that he is careful and detailed. You can see that he takes great pride in his work and you can rest assured that not only does it look amazing - it has also been done properly and impeccably.

There isn’t anything that I have been unsatisfied with (nor any of the members). I have had a fair bit of experience with tradesmen/women and I understand how much of an impact picking the right person can have on your project/investment (not only with respects to workmanship but also your overall experience). Keeping this in mind I highly recommend Mario Tardif with Custom Wallboard Interiors for your renovation/restoration needs. I encourage you to call with any questions, as I would be more than happy to verbalize my praises for Mario with Custom Wallboard Interiors!

"As an Interior Designer, I've experienced many challenging high-end custom projects that require intricate design elements and a special talented craftsman to bring them to life.

Mario has worked for me in some of those projects and has produced excellent professional results.

I highly recommend Mario for any Home Improvement, Interior Remodeling, Home Renovation or Home Repair project. He is a skilled and specialized tradesman who always strives for perfection.

If you wish to speak with me personally, please, do not hesitate to contact me."

"To: Anyone considering the services of Custom Wallboard

Do not hesitate to use the services of Mario/Custom Wallboard. During the time Mario lived in Florida, he worked on several different projects in my home. Each one turned out beautifully with professional results.

Mario is a craftsman-----not just a drywall man! Some of the drywall units that he completed for me required intricate design elements and crown molding details. He was not only capable of the work required but offered valuable expert advice as the best way to approach the "tricky" aspects of the job. He was always right!

My only regret is that he has moved away. My loss is Kelowna's gain!

If you are looking for a reliable professional in drywall field, honestly---look no further. I can say with confidence---you will not be disappointed.

Please, feel free to contact me if necessary."
