Fence and Deck Building & Repair Experts
Working With Wood builds decks in Pelham, including Fonthill, as part of the ten Niagara towns we serve. Ballpark ranges only, not a quote: larger deck builds across the wider Niagara Region commonly run $15,000-$35,000, and professional deck upgrades in Niagara trend $35-$75/sq ft. Ontario-wide, installed decks generally run $45-$95/sq ft (pressure-treated wood $45-65/sq ft, composite $65-95/sq ft). These are wide 2026 marketing-content ranges. We have no Pelham-specific price figure, so we are not making one up. Size, height, site access and material set your real number, and an on-site estimate is the way to get it.
Pelham sets its own deck trigger, and it is about height, not size. The Town's 2026 Building Permit Guide (revised February 2, 2026) lists "WOOD DECKS: greater than 24 inches (600 mm) above ground level" among the projects that need a permit. A low deck under that height does not trip the deck line. A porch or sunroom built onto the house is a different matter: the Guide puts additions on the permit list "even if under 108 square feet (10m2) in area", and names porches as an example. You apply through the Town's online building permit portal. Staff first check the drawings against the Zoning By-law. If they comply, the Town sends a statement for the "Permit Application Fee of $299.00", which is non-refundable, and the file then goes to a plans examiner for the Building Code review. The fee table lists decks on one row with garages, porches, sunrooms and sheds. Its fee cell is printed "$299.00 / $0.99> / 300/ft2". We read that as $299 for a deck up to 300 sq ft and $0.99 a square foot above that; the Town does not spell it out, so ask when you apply. The Guide also says a minimum permit fee of $299.00 applies, that fees rise with the Consumer Price Index every January 1, and that "the permit fee shall be doubled" if work starts before the permit is issued. Pelham is reviewing its building permit fees this year (a public meeting was held June 17, 2026), so confirm the current figure.

Pelham's Comprehensive Zoning By-law 4481(2022) (office consolidation August 11, 2026) defines a deck as a structure "over 0.6m above any part of the finished grade of the adjoining exterior wall" with no walls or roof. Two rules follow from that. An uncovered deck may project up to 4 m into a required exterior side yard or rear yard (s.3.7). And an attached deck more than 0.6 m above grade counts toward your lot coverage, as does a covered porch, while a patio does not. How much rear yard you have to work with depends on your zone, so check it before you settle on a deck size. Part of Pelham sits in the Niagara Escarpment Plan area, shown on the by-law's Schedules A and C. There, the by-law says a Niagara Escarpment Commission development permit may be needed "before a building permit can be issued". A separate approval can also apply anywhere in town: the Niagara Peninsula Conservation Authority (NPCA) covers the whole Niagara Region under Ontario Regulation 41/24, for a property in a wetland, within 30 metres of one, or on certain other hazard lands. The regulation exempts "an unenclosed detached deck or patio that is 15 square metres or less, is not placed within a watercourse or wetland and does not utilize any method of cantilevering" (s.5(a)(v)); a deck attached to the house gets no such exemption.
Pressure-treated wood costs less upfront and looks natural, but in Ontario's climate it wants re-staining or sealing roughly every 1-2 years and its boards wear out sooner. Composite costs more to buy and needs little yearly finishing, and it holds up well against Ontario's 40-60 freeze-thaw cycles a year, which is the real test for any deck in Pelham. The higher composite price often evens out against wood upkeep around the 8-10 year mark, depending on how well the wood deck is kept. For the full comparison, see the decking material guide.
Yes. Pelham, Fonthill included, is one of the ten Niagara towns we serve. We build wood and composite decks on site, and we repair existing wood decks.
You do if the deck is more than 24 inches (600 mm) above the ground. That is the line in the Town's 2026 Building Permit Guide. A porch or sunroom added to the house needs a permit at any size. Apply through the Town's online portal, and call the Building Intake/Zoning Technician (905-980-6683) if you are unsure.
The Town collects a $299.00 non-refundable Permit Application Fee once your drawings pass zoning review. The deck row in its fee table is printed "$299.00 / $0.99> / 300/ft2", which we read as $299 up to 300 sq ft and $0.99 a square foot above that. Pelham is reviewing its building fees in 2026, so confirm the figure when you apply. Starting before the permit doubles the fee.
Zoning By-law 4481(2022) lets an uncovered deck project up to 4 m into a required rear yard or exterior side yard (s.3.7). The yard depth it projects into depends on your zone. An attached deck over 0.6 m high also counts toward lot coverage.
Pool By-law 3389 (2013) requires a pool fence of 1.5 m to 1.82 m (s.4.4). Where a deck or platform forms part of the enclosure, its edge needs a continuous guard at least 900 mm above the deck and at least 1.5 m above grade (s.4.11). Pools need their own permit from the Town.
Wood costs less upfront but needs re-staining every 1-2 years. Composite costs more and needs little upkeep, and it handles Ontario's freeze-thaw cycles well. The price gap often closes around 8-10 years.
