The 5 Best General Contractor Firms in Ottawa

If you’re looking for someone to oversee the day-to-day progress of your construction site, you’re definitely going to be needing a general contractor. One you can really depend on as you go and focus on other work.

This job is no joke because, almost quite literally, your whole construction will be in their hands as they communicate with you, subcontractors, laborers, suppliers, and the like. This is exactly why you’ll be needing this list of the top firms with the best general contractors in Ottawa!

What to Know Before Hiring a General Contractor Service

A general contractor is a must for anyone with a construction project in mind since they keep the wheels turning while you go off and do your thing. Before you hire one, here are a few things you need to know before hiring one:

1. Do you have anyone you can ask for referrals?

It’d be a smart choice to ask friends and families about general contractors they’ve worked with in the past. This will help you a lot since those would be reviews from people you know personally and you know you can trust.

2. What services will you need for the job?

Know exactly what it is you want out of the project, the contractors, and how you want it done. This makes it easier to communicate those wants to your general contractor so you’re both on the same page.

3. Are the general contractors you’re looking at permitted?

First, are they permitted to do the type of work you’re looking at them to do? Second, just to be sure, are they capable of requesting the town or city permits you’ll be needing for this project?

4. Contracts save you.

Contracts are there for a reason and they’re there to save you from any potential mishaps so be thorough. Draw up a precise contract with all the details you and your contractor have talked about; time frame, budget, laborers, all that.

5. Frequent communication is a must.

Even if the general contractor’s job is to keep everything in order, it’s still important that you’re both in frequent communication so you know how the project is going. This also lets them know you’re on-top of everything and so they won’t try to cut corners.

How Much Do General Contractor Services Cost in Ottawa

General contractor service fees vary on a case to case basis so we really can’t give you an estimate however they usually charge around 20-30% of the entire project cost.

It can be tempting to want to forgo a general contractor but, in reality, the percentage they charge isn’t that high if you consider the risks you’ll be avoiding by hiring a professional and the fact that your hands will be free of the project and dealing with subcontractors.

Top General Contractor Services in Ottawa

If you’re going to delegate something as important as your construction project to someone else, you’re gonna want to make sure it’s with someone you can trust based on their skills, their work ethic, and all that.

We give you a guarantee that the top general contractors in Ottawa are gonna help you get the job done just the way you want it!

Ottawa General Contractors is the leading contracting company in Ottawa. Their team grants you access to a full service experience wherein you don’t need to hire separate interior designers, laborers, and other construction services separately.

Customer Reviews

Here are a few reviews of satisfied clients of OGC:

“The actual work that OGC did on my interior renovation was good and the finished product looks very nice overall, working with them was a good experience. I understand that renovations sometimes take longer than expected and our house is quite large but the end date we were told was the end of April.” -Joseph

“It has been 8 months since Ottawa General Contractors finished up the work on converting our very wet, damp Cold Storage space into a very dry and usable storage space. Both the inside and outside of the Cold Storage space and along the front of our house were sealed and insulated. It made an incredible difference in our basement. Warm and dry!

The deck that was built on top of the sealed and insulated old exterior concrete stairs on the front of our house is beautiful. From beginning to end OGC was professional, courteous, and kept us in the loop as the project proceeded. It was a pleasure having OGC handle this ‘Little Big Project’ from start to finish.” – Scott

Customer Reviews

Here are a few reviews of satisfied clients of Art & Stone Group:

“The Art and Stone Group is an amazing company. We’ve done renovation and one new build and can not recommend them enough. They’re responsive, fulfilled time lines and provide the highest quality of work. Andrew and his team keep the work site clean and he is on site daily to ensure the project stays on track. Alex’s design skills were so appreciated.  She saw my vision and helped me bring it to life, while staying within our budget! It’s clear by their work ethic and professionalism that they care about their clients and the service they provide.” -Meghan

“The best decision my partner and I made upon purchasing our new home was deciding to work with the Art and Stone Group, led by Andrew and Alex, to both design and finish the basement and redesign/renovate certain aspects of the living space on the main floor.  Not only was our project completed on time, but their quality of work and attention to detail was unparalleled to experiences we had had with home improvements in the past.  From day one, Alex and Andrew took the time to understand our taste and our lifestyle, and how to marry the two in order to provide us with a space that we would be happy with for years to come.  When challenges arose (as they inevitably do with major construction or renovations), they always took the time to explain things to us and offer us alternative solutions that we would be happy with.  We are entirely grateful to the Art and Stone Group for the work they did for us in our home and cannot recommend them more highly!!” -Jessica
