About Us

We understand that selecting a contractor is not an easy decision and with so many claiming to be the best, who really is? The better question is who is the best for you, and that can only be determined if you do your research. To assist, we’ve broken the following information into some key words and phrases, including our core values, to explain more about us and how we feel about our valued customers.


Since 1968 we’ve been pleased to serve over 35,000 customers in the Greater Windsor area. We have a stellar reputation and a proven track record of standing behind our workmanship. At any given time, we have thousands of homes under our protection. We own our business establishment, with an office, showroom and warehouse. We don’t operate from a residence, post office box, or rental and our main telephone line isn’t a cell number. Our sound business policies have provided us the success we need for financial stability, enabling us to have solid roots in our community. This gives you greater peace of mind in knowing we’ll be around in the future.


There is always a certain amount of uncertainty associated with a renovation project. You don’t always know what’s behind an old roof or wall covering, for example, until it’s removed.

With over five decades of experience however, there isn’t too much we haven’t encountered. Our experience will make the whole renovation process as simple and stress free, for you, as possible.


We won’t sell you something you don’t need or pressure you into signing a contract. In fact we feel more comfortable if you take all the time you need, as we’re confident that the more thought and research you do, the better chance we have of earning your business. We don’t have commissioned salespeople, so there is never any motivation to up-sell. We give you options and guidance, but don’t force decisions upon you. Our estimators are either present or former installers, not slick salespeople.


Being a family operated business with four generations of experience, integrity is at the heart of everything we do. The BBB has acknowledged this by presenting us with two (Windsor as well as Western Ontario) Integrity finalist awards and we’ve maintained an A+ rating since we became a member over 45 years ago. All this, during a time when contractors typically rank among the highest BBB complaint categories.

Peace of Mind

A lot of businesses in our trade don’t survive. Dozens of former competitors are no longer in business today and the list continues to grow. We’ve been in business for over 50 years. Rest assured we will be around should you need us in the future. In addition, we have adequate insurance, WSIB coverage and most jobs don’t even require a deposit.

Customer Service

Customer Service We have a strong customer service culture that every employee understands. We don’t just work for customers, we build relationships with them.

As we offer so many services we want to work for our customers for life. This is one of the reasons why so many customers recommend us and why nearly 80% of our work comes from previous customers and referrals.



Since our estimators have an installation background, we have the knowledge to answer your questions and put together the right scope of work, customized for your project.

This is crucial, as even the best installers can’t perform properly under poor guidelines. This is why it’s compulsory for our estimators to have installation experience. We feel that it’s more valuable than sales experience.


We fully understand that the trust and faith customers place in us is not to be regarded lightly. We also understand that, for most people, their home is their single biggest investment. It’s important, in any business, to treat customers with respect, but we feel it’s most important when customers allow us the privilege of working on their homes.


We guarantee that you will get exceptional value for your hard earned money. Sometimes people get the impression that we must be the “low price” contractor because they see our job signs all over Windsor and a good portion of Essex County. Frankly, this is not the case. It’s impossible to provide our level of craftsmanship and service, with the quality of materials we use, and be the lowest price. Our pricing is competitive, not the lowest. Typically we find that the low price contractors don’t survive for very long. We’re the “contractor of choice”, not because of pricing, but because of the value we offer and our commitment to excellence.


Our customers regularly tell us that they have never experienced such open communication. We keep our customers informed through the whole renovation process and we are available well outside of business hours by email or through our answering service.


We are factory-trained and certified with several manufacturers. We are also Window Wise trained, having passed their comprehensive National installation training program (also known as SAWDAC FIT training). Training is on-going to stay up to date with the latest installation techniques and we even have our own in-house training center, where we’ve developed our own specialized installation methods. We also feel its best not to train on your home. Our success is really in our people. Our installers take pride in their work and have a genuine concern for our customers.


You can always be sure that you will be treated with the respect you deserve. We’ll give your home a thorough inspection, take pictures and provide you with a detailed typed estimate. We often catch things that others have overlooked. Without this attention to detail, your renovation experience can quickly shift from enjoyable to unbearable. We also follow-up on every job to ensure your complete satisfaction.

Multiple Services

We offer complete exterior renovations. This means you won’t have to deal with, and coordinate, several different contractors. It also eliminates “finger pointing” between contractors. We can give your home a complete exterior facelift in one continuous job, or the project can be spread over time. Our experience in planning each phase, even if the phases are spread over time, can be invaluable. You don’t want to go to the expense of modifying a previous renovation, to accommodate a new phase, when it can be avoided.


All our employees specialize in a trade, which makes them exceptionally good at their particular field. This way, you can be assured that you will be getting true craftsmen working on your home. You won’t find our roofers installing windows or our siding installers doing roofing.
