what we do
Windows & Doors for Renovations and New Builds
Every window and door install begins with a proper understanding of the opening, the surrounding building envelope, and the conditions that will affect how the unit performs over time. Our work is based on building-science fundamentals, which includes making sure each step is sequenced correctly and tied into the water, air, and vapour control layers the way it should be. We specialize in renovation projects, but we also support builders and developers on multi-family, commercial, and new construction jobs throughout Victoria and Vancouver Island. Each installation complies with building code, respects product requirements, and reflects the same operational standards across every project.
Single-Family Homes.
Renovation and replacement work make up most of our residential projects, and every home tells a different story. Older houses often come with a mix of worn membranes, uneven framing, past “patch jobs,” and finishes that need to be protected while the openings are rebuilt. We take the time to evaluate each situation and determine whether a full-frame replacement, a retrofit approach, or a blended method will give the best results for the home’s envelope and long-term durability.
From there, the install is carried out in the right order, tied properly into the existing WRB, and supported with the correct shims, fasteners, and sealing methods to meet both manufacturer guidelines and current Energy Code standards. Our team includes a Red Seal–certified glazier – uncommon in this line of work – which brings an added level of precision and skill to every project. For homeowners, that means tidy work, clear documentation, and a performance-driven installation, not a glass-only band-aid that fails a few seasons later.
Water Management.
A window performs only as well as the envelope around it — most long-term failures happen because the opening was never tied back into the water, air, or vapour control layers correctly.

Multi-Family Window & Door Systems.
Multi-family projects demand consistency and tight coordination, especially when dozens or of openings need to be completed on schedule. We work directly with site supervisors to plan out sequencing, lock in product details early, and keep a steady installation rhythm that supports the overall build timeline. Our standardized approach ensures each opening is handled the same way, no matter the unit or floor.
On site, we deal with the usual variations in framing, maintain membrane continuity, and handle anchoring, alignment, and sealing with a methodical, repeatable process. If something in the envelope doesn’t look right, we’ll address it immediately so it can be fixed before it becomes a slowdown. Builders know they can count on our installs to pass inspection, meet safety expectations, and reduce follow-up work – all crucial elements on fast-paced developments.
Renovation Complexity.
Re-and-re work demands careful assessment. Hidden conditions behind existing finishes often determine whether a retrofit, full-frame replacement, or combination method will perform properly.

Supporting Commercial & Retail Spaces.
Commercial and retail spaces place heavier demands on doors and glazing systems. High-traffic entrances, mixed façade materials, and structural requirements all influence how an opening needs to be prepped and installed. We work with storefront assemblies, commercial-grade glazing units, and specialty doors, paying close attention to anchoring, support, and how each system ties back into the building envelope.
Our detailing accounts for the transitions between concrete, metal cladding, engineered wall systems, composite panels, and other exterior finishes. Sealants, fasteners, and WRB connections are handled with the precision needed to maintain long-term air and water control. Contractors know we always follow WorkSafeBC protocols, coordinate cleanly with surrounding trades, and complete our commercial scope without creating conflicts with the work happening around us. We’re proud of the reputation we’ve built in the Victoria area and continue to exceed contractors’ expectations on every project.
Building Science Matters.
Correct sequencing is essential; one missed step in the installation or envelope detailing can compromise the entire opening, even with high-end products.

Ground-Up: New Construction Projects.
New construction projects, whether a single-family home or a multi-residential development, depend on early coordination and clear communication so each opening can be integrated smoothly as the structure takes shape. We review drawings up front, confirm that the chosen products suit the design intent, and aren’t afraid to make recommendations when envelope details or installation steps need adjustment.
Specialty systems, such as lift-and-slide doors, stacking configurations, and bi-fold units, require precise positioning and careful tie-ins to the surrounding envelope. Our installations always follow the correct sequencing, meet Energy Code expectations, and align with manufacturer requirements to ensure each unit performs properly from day one. Developers have come to rely on our safety awareness, steady communication, and that our work always fits cleanly into the broader build without disrupting other trades on site.
Built to Last.
Quality materials and proper installation techniques work together to create window and door systems that perform reliably for years to come.

Custom Shower Glass.
Frameless glass shower enclosures create a clean, modern look while helping bathrooms feel more open and spacious. Island Horizon installs custom glass shower systems designed to fit each space precisely, whether as part of a renovation or a new construction project.
Each installation begins with careful measurements and preparation to ensure the glass panels align properly with surrounding tile, walls, and hardware. Attention to waterproofing, sealing, and mounting details helps protect the surrounding structure while ensuring the finished enclosure operates smoothly and reliably over time.
what you'll get
A Consistent Approach, Every Project.
Every project is different, but our process stays consistent. We assess conditions, choose the right approach, and execute each opening with careful attention to sequencing and envelope integration. The goal is simple: work done correctly the first time, so performance problems don’t appear later.
