Frequently Asked Questions
Deck construction costs in Markham depend on size, height, design, materials, foundations, stairs, railings, site conditions and finishing details. Wood and composite decking can also have significantly different material and maintenance costs.
Wood can provide a traditional appearance and different initial cost options, while composite decking is designed for lower routine maintenance. Compare appearance, durability, maintenance, installation requirements and total project cost.
Some decks can be repaired when the underlying structure remains sound. Significant deterioration, movement, damaged structural components or an unsuitable foundation may make partial or complete replacement more appropriate.
Permit and building requirements vary by municipality and project design. Deck height, size, location, stairs, guards and proximity to property lines can affect requirements. Confirm local rules before construction begins.
The schedule depends on project size, design, materials, site preparation, permits, weather and contractor availability. A straightforward deck may take less time than a raised or highly customized structure.
Compare experience, materials, structural approach, design options, permits, written estimates, project schedules, warranties, previous projects and recent local reviews.
