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 will discuss it with you. We design + build everything from bathrooms and decks to large additions and whole home renovations. We also can offer repair services and small tuneups to your existing home.


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 is best to have one of our team members visit 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 generated for a small fee which will help with estimation activities. Once you become excited about the proposed designs and ideas for your renovation, Duo can provide a detailed budget breaking out all categories and costs for your renovation at no additional cost. Your home is now well on it’s way to becoming your dream home!


How is DUO different from other contractors?


We are an established company since 1979! 35 years. Our impeccable reputation is that of quality and service. 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 many satisfied customers many of whom return for a second, third or more projects.

The DUO Team

We provide a friendly licensed carpenter who is onsite every day and on time to make your project a reality.

The Duo Cloud

Success in construction projects is based on how well we communicate. We do this in spades with our new secure Duo Cloud web based system. This acts as a 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 right online providing a very fast turn around on unanticipated changes which would otherwise hold up the schedule. Speaking of which, we also provide a full schedule online that you can follow keeping you up to date with what’s going on that day, week or month. 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 is the first step for initiating my project?

Call us, email us or come by our office then let us do the rest! Duo Building is a full service design build renovation specialist. We know how to do what it is you’re hoping to achieve. Let us guide you through it.


How does your process work?

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

Step 1 – Give us a shout

Send us an email or call our office. We look forward to connecting with you in the near future.

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 – Can I Introduce Myself?

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 house 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 two year warranty on our workmanship. We’re famous for no hassle service well after we leave. You really do have piece 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 want the asap option, others choose the six months out package. What ever your needs we’re here to serve. 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.
