Fence Building
Custom fences built to property line, to code, and to last — privacy, security, and curb appeal in one investment.
Fence Building in London & Southwestern Ontario
A properly built fence is one of the most functional investments a homeowner makes. It defines property boundaries clearly, creates private outdoor space, secures a yard for children and pets, and adds visual structure to a property. Master Decker has been building custom fences across London, Woodstock, St. Thomas, Brantford, Hamilton, and the surrounding region since 2014. We work in pressure-treated pine, cedar, vinyl, and ornamental metal — whatever material suits the application, the budget, and the look you're after.
- Site visit, property line and grade review, and written fixed-price estimate
- Frost-depth augered post holes set in concrete with drainage grading
- Posts, rails, and boards in your choice of PT pine, cedar, vinyl, or ornamental metal
- Gate construction with double-hinges, positive-latch hardware, and diagonal bracing
- Grade-change accommodation with stepped or raked panels as required
- Bylaw height and setback verification before any work begins
Material for Every Application
PT pine, cedar, vinyl, ornamental metal — we match the material to your maintenance preference, budget, and neighbourhood.
Frost-Proof Post Setting
Every post goes below the frost line in concrete — the only installation method that keeps posts plumb through Ontario winters.
Gates That Stay True
Diagonal-braced gate frames, rated hinge hardware, and positive-latch systems — our gates still swing and latch properly after years of use.

Why fence building matters in Ontario's climate
We don't do cookie-cutter fence installations. Every job starts with a property line conversation, a review of any HOA or municipal bylaw height restrictions, and a look at the grade changes along the fence run. Sloped lots need stepped or raked fence panels to follow the grade without gaps at the bottom — and that's a detail that gets sorted in planning, not in the middle of installation. Written estimate, fixed price, no change orders.
Material Guide: Wood, Cedar, Vinyl, and Ornamental Metal
Pressure-treated pine is the economical workhorse. Posts are ground-contact rated, rails and boards are above-ground rated — correct material for each application. PT fences are typically stained or painted within 6–12 months of installation once the wood has dried. Cedar is the premium wood choice — lighter, straighter, naturally rot-resistant, and beautiful when stained. Cedar is popular in the London, Kitchener, and Hamilton markets where homeowners want a wood look with lower long-term maintenance.
Vinyl fencing is fully maintenance-free — no staining, no rot, no insect damage. It comes in privacy, picket, semi-privacy, and ranch-rail profiles. Cellular vinyl is rigid enough to span the same post spacing as wood. Ornamental metal (powder-coated steel or aluminum) is the commercial-grade option: estate-look posts and rails, finial caps, and decorative pickets. Popular for front yards, pool enclosures, and properties where visibility matters but security and style are the priority.
Installation Process: Posts, Rails, and Getting Grade Changes Right
Post installation is where fence longevity is determined. Every post we set goes into an augered hole below the frost line — 900 mm to 1.2 metres depending on post height and local conditions. Posts are set in concrete with proper drainage grading away from the post base. We use post-setting foam for sites where concrete curing time is a constraint. Posts are plumbed and aligned on a string line before any rails or boards go on — there's no shortcut here that doesn't show up in the finished product.
Rail attachment is done with approved hardware — joist-hanger-style brackets for structural integrity, not toe-nailed connections that pop out over winter. Privacy fence boards are face-nailed or screw-fastened with a consistent reveal and a bottom clearance of approximately 50 mm above grade to prevent direct soil contact. Gate hardware is heavy-duty — double-hinges rated for the gate weight, a positive-latch system, and a diagonal brace in the gate frame to prevent sag. We build gates that still swing true after five winters.
Bylaws, Property Lines, and What to Check Before You Build
Most Ontario municipalities cap fence height at 2.0 metres (roughly 6.5 feet) in rear yards and 1.2 metres in front yards, though specifics vary by zone classification. HOAs may have additional restrictions. Master Decker identifies the applicable height limit and any setback requirement at the estimate stage. We also recommend confirming your property line with your survey certificate before installation — a fence built 0.3 metres onto a neighbour's property is an expensive problem to resolve after the posts are set.
Fences along shared property lines may require neighbour notification in some municipalities, and cost-sharing agreements are sometimes involved. We're experienced navigating these conversations and can advise on the process. We carry WSIB coverage and liability insurance, and our workmanship guarantee covers post, rail, and board installation defects. From the first site visit to the last board fastened, you deal directly with the Master Decker crew — no subcontractors.
Common Questions
Fence Building FAQs
How high can I build a fence in London or the surrounding area?
Most Ontario municipalities allow up to 2.0 metres in rear yards and 1.2 metres in front yards, but local bylaws vary by zone. Master Decker confirms the applicable limit for your specific property at the estimate stage — you won't find out you've built the wrong height after the posts are in.
Do I need a permit to build a fence in Ontario?
Most residential fences under the standard height limit don't require a building permit, but some municipalities require a fence permit or property owner agreement for boundary fences. We'll confirm what your municipality requires before the project begins.
How long does a wood fence last compared to vinyl?
A properly built cedar fence, regularly stained every three to five years, can last 20–25 years. Pressure-treated pine is similar with maintenance. Vinyl lasts 30+ years with minimal upkeep — no staining, no rot. Ornamental metal with powder-coat finish can last decades with occasional paint touch-ups on cut ends.
My yard has a slope along the fence line — is that a problem?
Not if it's planned for. Sloped lots are handled with either stepped panels (each panel level, with gaps under the low end filled with trim boards) or raked panels (the fence follows the slope continuously). We look at grade changes during the site visit and recommend the approach that looks best for your specific fence style and slope degree.
