Do you charge for an estimate?

Estimates are free. And so is our expertise!

If your renovation requires a site measure and preliminary drawings, we do charge a nominal fee to do so. When the contract is signed, we refund any charges previously made for a site measure and preliminary drawings.


Is my project too small for DUO Building?

Probably not, call us! We’ll happily discuss it with you. We design + build everything from small office conversions to new building developments. We also offer repair services and small tune-ups to your existing office.


How much will my project cost?

Construction projects have a notoriously high number of variables to consider. In order to provide an accurate budget for your requirements, it’s best to have one of our team members meet with you to discuss your needs and wants. After the initial visit and a high level discussion about the scope of work required, a site measure is usually needed to provide accurate measurements on the existing building. A proposed layout can then be created for a small fee that will help with estimation activities.

Once you feel comfortable with the proposed designs and ideas, DUO can provide a detailed budget that outlines all material categories and costs for your renovation at no additional cost. Your space is now well on its way to becoming your dream commercial space!


How is DUO different from other contractors?


We are an established company founded in 1979! 35 proud years of transforming homes and offices in London. Our impeccable reputation is that of quality and service with a personal touch. Not everyone can say they’ve been around as long as DUO. This means that again and again, we have produced top quality projects to countless satisfied customers many of whom return for a second, third or more projects.

The DUO Team

We provide a friendly licensed carpenter who is on site every day and on time to make your project a reality. The carpenters of DUO Building are backed by a strong team who between them hold more than 150 collective years of construction experience. Our sub trades share the same professionalism and dedication to quality that DUO expects of ourselves and due to our high volume of projects, sub trades always provide their services to us promptly. Take a look through the About Us section of our website to learn more about who we are.

The DUO Cloud

Success in construction projects is based on how well we communicate and keep our clients comfortably informed. We do this in spades with our new secure DUO Cloud web-based system. This acts as a user-friendly home base to your renovation activities. Carpenters provide log entries and pictures for job progress along the way. Change orders are delivered via the DUO Cloud and you can approve them easily online, providing a very fast turn around on unanticipated changes that could otherwise hold up the schedule.

We also provide a comprehensive schedule online that keeps you up to date with what’s going on that day, week or month on your project. Any questions? You can now ask your Team Leader, Carpenter or even the Project Estimator a question through the DUO Cloud. By doing so, your inquiry is seen by all stakeholders in the project and answered promptly and accurately by the appropriate party.


What kind of renovations do you do?

From the smallest renovations to large scale commercial renovations, DUO Building has experience delivering a wide scope of projects. Dental and optometry offices, vet clinics and spas renovations are just a sampling of what we’re about. We’re adaptable and ready to help you realize your goals whatever they might be.


I've heard DUO is more expensive than other contractors, is this true?

DUO Building is not expensive, we are realistic, honest and comprehensive. We firmly believe in providing an extremely detailed and accurate budget from the start to accomplish 100% of your project scope. During the quotation phase, it may be tempting to seek the lowest price, but beware of potential additional costs that often “pop up” along the way with other contractors. Read each contractor’s proposal carefully to avoid disappointment.

At DUO, we offer exceptional VALUE PER DOLLAR by providing a complete service from design to post-construction service complete with the peace of mind of a 3-year warranty.

We will provide you with a well-written contract that accurately specifies what you will get for your money, no surprises! We only use skilled trades and professionals who are excellent at what they do and stand behind all of their work. We handpick our team to work on each project. Personal customer service and ongoing communication is key to ensuring the projects are done well and meet our customers’ needs.

We have a transparent and accurate method for project changes as they come up so that you can decide in advance if you want to go ahead. We keep you informed and involved all the way through the process.

We happily service what we build. Just call us and we will be there for you.


What is the first step for initiating my project?

Call us, email us or come by our office. We are happy to answer any renovation questions you may have or set up an appointment at your home or office to discuss your project. DUO Building is a full service design + build renovation specialist for both residential and commercial projects. Let us guide you through the process and transform your space.


How does your process work?

Let’s look at seven steps that turn your dreams into realities, comfortably.

Step 1 – Give us a shout

Speak with a team member and briefly describe what it is you’re hoping for. Your project is now started! A renovation consultant will return your call within one business day to schedule a meeting.

Step 2 – Wanna Meet?

One of our very experienced representatives will meet you to listen to your needs. Our goal is to start a long lasting relationship right from day one. You will be impressed with our team from the moment you call, email or visit. Friendly, knowledgable and interested in providing creative, solid recommendations towards your goals.

Step 3 – Designs and More Consultation

Moving forward with your renovation from the discussion stage means putting pen to paper (these days usually a mouse click or two) and creating an ideal, creative and accurate layout to baseline the projects scope. To do this a site measure is required. We measure every nook and cranny in the place! A professional existing and proposed layout is then generated. It is at this point the estimation team gets busy crunching numbers. A detailed budget with construction category breakdown is provided to give you a better idea of your project costs. Often we initiate a trade visit where sub trades are scheduled to meet with us at your house. We provide those experts such as plumbers and electricians with all the required information. This also provides you with a great opportunity to meet the sub trades who will also be responsible for delivering perfection.

Step 4 – The Seriously Friendly Contract

Once again you’ll meet with your DUO rep for a presentation of your proposal. A very detailed list of activities is presented line by line, answering any more questions or concerns you may have along the way. Some items in the contract might change during this meeting, no problem! We’ll adjust accordingly to make sure you’re comfortable with every line. When you are confident in the proposal we ask you sign the contract and provide a 10% deposit. Now you’re part of the Duo Building family. Your project is immediately put in line for a start date and is one step closer to completion.

Step 5 – Meet your Team

A project Team Leader will contact you (often the same guy you already know) to set the official start date. On that day we’ll show up to your door armed with the required equipment to start protecting your space from renovation activities. Before prepping the renovation, you’ll meet the Lead Carpenter who is responsible for the most important part, building your dream. A DUO Cloud account is easily set up with a simple email to you that allows you to create your own personalized sign in. There you can see a schedule, the days weather and any documents or photos relevant to your project.

Step 6 – We Build It

That simple. Working with you every step of the way.

Step 7 – Final Walk-Through

At the end of it all, your project team leader meets with you for a walk through of the project ensuring all deliverables promised are met. But that’s just the beginning! Six months later we call to ask “everything ok?”. We also provide a 3 year warranty on our workmanship. We’re famous for no-hassle service well after we leave. You really do have peace of mind when you choose DUO Building as your contractor.


When would you be able to start?

Let us know when you would like to start. Some clients want the ASAP option, others choose the six months out timeline. Whatever your needs, we’re here to make your project a reality. We’ll do everything in our power to start at a convenient date for you. That being said, if things are busy for us, we’ll let you know early in the process so there are no surprises.


How far will you travel for projects?

Proudly based in London, Ontario, we will also travel up to 100km to surrounding communities. We have completed commercial renovation projects in Chatham, Stratford, Grand bend, Burling, St. Marys, Delaware and Port Stanley just to name a few.
