Exterior Carpentry

Spring is barely at our doorsteps and you are already thinking about your summer landscaping project? The construction of a new patio or terrace is part of your plan? Before undergoing such project, it is important to shed light on certain factors:

Establish a plan: This recommendation is especially important if you don’t know where to begin. Specializing in landscaping and horticulture projects, Conception Horticole du Nord’s team posses all the skills required to elaborate a detailed plan according to your budget and style and design preferences.
Choice of coating materials: Once the budget is established and the initial plan conceived, it is time to select the essence and color of the wood (visible part of the patio) that matches your house.
Lifespan: You have to keep in mind that the choice of layout and materials you pick will have an impact on the quality and seasonal maintenance time of your patio or terrace.
Conception Horticole du Nord offers a complete selection of materials for your patio (red cedar, hemlock, composites, exotic woods, burnt woods, etc.), each offering unique properties that will answer various specific landscaping needs. To extend their lifespan and reduce costs, the structures are made of treated wood and the beams are protected with a waterproof membrane.
