Look for another contractor. They likely don't do the work they are supposed to and don't honor their warranty. Here are all the issues I have with the work they did:
Interlock:
1) they were supposed to raise the grade by 5-6 inches to avoid the need for a half step that was there before. They didn't raise the grade even 1 inch and instead went ahead and installed an extra step and didn't even say anything to me about it. I saw it after they had left
2) in the quote I had specifically asked that they put down 1 foot of base gravel in line with unilock technical guide and they even charged me extra for it. When I dug a couple of post holes after they finished putting in the base, I noticed there was only about 6 inches if not less.
3) before putting down the base material, the same unilock tech guide says that a permeable weed barrier fabric should be put in which helps prevent spread of the base material. They did not do this
4) when they finished, they left quickly and didn't finish putting in the polymeric sand on all the sides and had no intention of coming back to do it until I called them.
5) I have 2 semicircular window wells where the interlock was being installed. When the owner, Giorgio, came to quote me, he forgot to note the window wells so after a follow up call, he drew them as rectangular. When the guys showed up on site, they were confused by this even though I explained to them multiple times that they were never supposed to be rectangular. After a lot of back and forth I agreed to do a modified rectangular design which they then completely ignored and did the same thing they mentioned at the start. It looks ugly.

Asphalt:
This was the one thing I was happy with because initially it looked great. I even kept the car off the new driveway for a month (way longer than they suggested was needed) to ensure it cured sufficiently to avoid any tire marks. After parking on it for about 1 month, there was already a small crack in the middle of the driveway. They guy they sent out to take a look decided within 2 seconds that it was caused by tree roots and therefore not covered by the warranty. A quick Google search shows that tree roots are not the cause of driveway cracking if the tree is more than 5 feet away. The closest tree with any significant roots is 20 feet away. It also didn't seem to matter to him that the neighbors driveway (done by them at the same time) also had a crack about 30 feet away from the one on mine. There were other things that made no sense for it to be caused by roots but he would not budge and his solution to fixing it was to put some polymeric sand in it. I am no expert but I have never seen any cracks on city roads or other people's driveways with polymeric sand in it...but it sure is a cheap way to get out of doing a proper fix.

In terms of customer service, the office staff and the excavation/asphalt crew were very courteous but the interlock crew barely spoke any English and was very difficult to interact with.

Based on my experience, they'll do a job for a competitive cost but they won't do it right.

lots of lines and footprints shows up when wet, very obvious. Owner said will disappear overtime, I am doubtful but we will see

Had driveway done at my rental place. Team was flexible, friendly, open and reliable. They removed old wood, casted concrete side curbs. Clean and reliable work. Would def recommend them

This review is long overdue. We had contracted Northland Paving to totally transform our badly deteriorating driveway and walkway. Even though the project was pricey, it was certainly money well spent. The quality of the work and the the WOW factor of the result was worth every dollar. Giorgio and Sheila were amazing. They were very receptive to our questions and concerns. We highly recommend this company for your paving and restorative needs.

A big thank you to Giorgio and the crew for a job extremely well done.
Would very highly recommend Northland Paving.
Lots of compliments from passerby as well.
Worked together on time and great finishing touches.
Looking forward to enjoying our beautiful front entrance again.

From the moment Giorgio from Northland Paving came to my house for a quote, til the final paving day, the process was quick, professional and well done. I would not hesitate to recommend Northland Paving for all your stonework, and paving needs. All crews were professional, courteous, came in, did their portion and left my property clean!
I am very happy with the end result!
Thank you again Northland Paving!

I waited a year to write a review because I wanted to see how the driveway held up. Its great. Also since then other neighbors have had their driveways done by other companies so I could compare. Georgio was the best. His crew was like a well tunned machine. They worked amazing together. They were all very polite, informative and helpful. Unlike the other companies they left all the driveways, walkways and street absolutely clean. My neighbor found Georgio so there was a few driveways done. We still talk about how great they were. Georgio is a real professional who wants it done right. Thank you for an amazing job.

My neighbourhood is deluged with fly by night(here today, gone tomorrow) paving companies that offer cheap rates. Hearing of other people's experiences has made me avoid these. You get what you pay for!

My driveway was somewhat run down(cracks, vegetation growing, etc.) and the garage floor, which was installed in 1968 was becoming pock-marked and cracked. I had had 2 favourable experiences with Northland Paving in the past so I contacted them again on this job.

I wasn't disappointed. The estimate was thorough and well explained, the workers came exactly as scheduled and notification was given well in advance. The work itself appears to have been first-rate. I dropped by their office with questions a couple of times while the work was in progress and those present were very polite and knowledgeable.

Northland Paving is a long established company with excellent reviews in the area and those looking for good results will not be frustrated or upset.

I had to do concrete work along with the paving of a new driveway – which is about 50% larger than a normal driveway.

After seeing the positive reviews for Northland Paving, I reached out to Giorgio and he came to the house and looked over the work to be done. Instead of simply accepting all of the work that I wanted to have done, Giorgio gave me some excellent suggestions and actually changed the design for some of the areas where the work was being done. Giorgio is very passionate about his work and you can see he takes pride in the quality of workmanship that Northland Paving provides.

I ended up doing a “liquid stone” finish on the concrete and I cannot be happier as to how this is turned out. The work was outstanding but I want to warn you that it is not inexpensive. You do get what you pay for.

As a relates to the driveway, Northland Paving was so quick in removing and then repaving the driveway (about 2 months later), that I could not believe it. They truly know their trade.

A with any renovation, I ended up going way overboard on budget but the result has been so impressive that it is a conversation piece for everyone who visits our home now – i.e. everyone loves the liquid stone.

In summary, I highly recommend Northland Paving.

We were first introduced to Northland Paving through our neighbours who had used them for their driveway and were very pleased with the service and workmanship. Based on their enthusiastic referral and seeing the workmanship, we called Northland. Everything about this company is top notch, from their sales rep Georgio to Sheila the coordinator to the professional craftsmen who turn out a great job. I found the crew professional and they cleaned up at the end of each day and delivered exactly what we paid for. Over the years I have referred friends and clients. Thanks Northland!
