Do it the right way the first time

What You Need to Know Before Building a Deck

A new deck will expand your outdoor living space and increase your home’s value. If you’re hiring a professional to build it, it’s always a good idea to arm yourself with information before you meet with a contractor. You’ll also need to do your homework. Decide what you want and do some research to learn the basic components of a deck, know the limitations of your backyard, and get familiar with the cost of materials. That way, you won’t wind up with a deck that doesn’t fit your needs or, worse, is dangerous.

You’ll want to get at least three estimates for the deck, and don’t just rely on online estimates. Have the contractors come to your house so they can take accurate measurements, and see if there are any obstacles that may affect the layout of your deck. To help the contractor provide you with an accurate estimate,

If you plan on building your deck, be sure to research your local building codes and get a permit if needed. It is usually necessary for a deck over a particular height and square footage. Permits average about $500. You’ll also need to have your city or town building inspector or structural engineer inspect and sign off that the deck is compliant with local building codes — this is known as a certificate of occupancy. Don’t skip the permits or certificate of occupancy; not having these can come back to haunt you if you have an insurance claim or when you sell the home.


Building a deck or putting in a new porch? Longing to create that seamless indoor-outdoor flow? Techno Metal Post’s helical piles are the best foundation available to help you redefine your outdoor living space. Home owners and contractors can build or repair decks and porches effortlessly and be guaranteed a strong, stable, and durable structure.

A solid foundation is necessary for the construction of a deck. Often built with multiple levels, and sometimes a roof, the weight on the foundation can be very high. If you have an inadequate base, you risk costly repair expenditures. This same principle applies if there is a hot tub or other heavy objects on your deck.

Our helical piles are designed, engineered, and tested to the highest standards, ensuring they can withstand the heaviest loads and conditions possible.

“The ability to set the steel piles and build the same day greatly increases production. Added to the fact that I’m saving heaps of money in labour costs by not having to remove displaced earth, haul concrete and clean up the mess makes Techno Metal Post the only way to begin a deck project.” — Robin Tremblay Patio deck-art designs

Rubber Flashing On Deck Joists

Benefit’s of Flashing Deck Joists

Water and wood do not play nice together, and over a long period of time unprotected wood, even pressure treated can rot. But by protecting the wood, it can extend the life of your deck. Most decks are still framed with pressure treated lumber. Applying a self-adhesive membrane to the wood will keep the water off. This practice is currently not code but a better way to increase the longevity of your joists.

For best rot protection coverage you’ll want to apply this protective membrane to the following areas:

  • Tops of all the deck joists
  • Top of the center beam, any beams
  • Tops of your stair stringers
  • The bottoms where the wood comes in contact with the ground

The Real Benefit
Applying rubber flashing on deck joists prevents moisture from sitting on the tops of the joists which could have potentially caused rot. The space between deck boards is a haven for dirt, debris and leaves. When these items get wet they tend to hold moisture which is a major ingredient for rot.

When building a deck, I also like to have a full width, roll of Grace Ice & Water on hand. The reason is, you can wrap the outside runs in a single piece; no seams.
