I have been using their landscape construction services for over 2 years now and it’s been great so far Julia TsapkalovaTrustindex verifies that the original source of the review is Google. We had GTA Grizzly install a slip fence for us, and the whole experience was genuinely great. The team worked efficiently, kept the area clean, and the fence turned out really well-built. You can tell they care about the quality of their work, and it shows in the final result. It’s not easy to find contractors you can trust, but Denys and his crew were reliable from start to finish. Can’t recommend them enough! Sasha MavrodiiTrustindex verifies that the original source of the review is Google. Had a great experience with GTA Grizzly. They handled both the landscaping and deck for us, and everything looks amazing. Easy communication, fair pricing, and solid workmanship, definitely recommend them.
If you want to start a new deck project or update your existing deck, the best time to hire professional deck builders is spring or fall, as temperatures are mild and the weather is more favourable.
Deck construction in extreme temperatures can lead to delays and require more effort from the deck contractor team throughout the entire process.
The best time to build a deck depends on your area’s climate, so consider this aspect when hiring a deck company.
Here, you need to consider the size of the deck, the complexity of the work, the accessibility of the site (is it a backyard renovation or a rooftop deck), your location, and the type of materials (composite decking, PVC decking, ipe decks, etc.), as well as additional features in the landscaping design project (retaining walls, outdoor kitchens, etc.).
Usually, an average deck can take a professional deck builder from a couple of days to weeks. Contact our project managers to find out the construction time of your dream deck.
This depends on your local building codes. In many jurisdictions, you will need a permit for any deck attached to a building. The good news is that when working with a top deck builder, this part of the process can be handled by the company on your behalf. This way, you can enjoy your perfect deck or custom outdoor kitchen without the hassle of dealing with permits, which is absolutely amazing!
