We provide specialized maintenance and repair services for complex or aging glazing systems, focusing on quality workmanship and long-term solutions.

Experience and Expertise

We are glazing specialists. Our core team has decades of hands-on experience in the glazing trade, spanning everything from residential window fixes to major commercial façade installations. This breadth of knowledge enables us to approach maintenance and repair with an understanding of the underlying building science and glazing system design. When faced with a tricky leak or an unusual custom window, we have solved a similar problem before.

Union-Trained Quality

As a strong unionized business, we take pride in the training and professionalism of our glaziers. Union certification and the Red Seal training program ensure that our workers are highly skilled in all aspects of glass installation and repair. The advantage to our clients is clear: jobs get done correctly and safely, following proper procedures. Our technicians know and respect building codes, safety regulations, and the high standards of workmanship.

Our success is measured by your peace of mind knowing that a competent, reliable team is looking after your glazing needs.

No Job Too Big

Have a 30-story tower with failing window seals? A massive showroom glass wall that needs re-sealing? A multi-building strata complex that requires annual care? We have the capacity and organization to take on large-scale projects and see them through successfully. Our versatile team structure allows us to ramp up for major jobs or deploy small teams for detailed custom work as needed. We love a challenge and have a proven track record to back it up.

Our seasoned glaziers provide end-to-end solutions to maintain, repair, and upgrade your glass installations.

Comprehensive Glazing Services We Offer

Leak Investigation and Repairs

Using proven diagnostic techniques, we pinpoint the causes of water ingress around windows, curtain walls, and skylights. Our team conducts thorough visual inspections and, when needed, controlled water spray testing to trace leak paths. We address issues such as leaking window frames, faulty skylight seals, poorly installed flashings, and aging caulking or gaskets. By repairing or resealing these weak points, we stop current leaks and prevent future ones. Routine inspection and maintenance of window seals, caulking, and drainage can greatly reduce the risk of leaks from the outset.

Sealant Replacement and Re-Caulking

A core part of our maintenance work is replacing deteriorated sealants that are no longer doing their job. Over years of UV exposure and weather, window perimeter caulking and panel joint sealants can crack or lose adhesion. We expertly remove failed caulk and apply fresh commercial-grade sealants (silicone, polyurethane, hybrids) chosen for durability and compatibility with your building. All our sealing is done to professional standards, ensuring a weathertight envelope. Those components are repaired or enhanced as needed to fully solve the water ingress issue.

Window and Door Hardware Maintenance

It’s important that your windows and glass doors operate smoothly and securely. Our technicians service all types of window and door hardware – hinges, handles, locks, sliding tracks, closers, and more. Regular upkeep of these components is crucial to ensure they continue to function at maximum efficiency for both ease-of-use and security. We lubricate moving parts, adjust alignment of sashes and doors, and replace any faulty mechanisms. By keeping the mechanical aspects of your glazing in top shape, we preserve the everyday comfort and protection your windows and doors are meant to provide.

Insulated Glass Unit Replacement

Foggy double-glazed windows, cracked panes, or failed glass units are not just eyesores – they compromise your insulation and can indicate further issues. We offer efficient replacement of insulated glass units (IGUs) and other glass panels as part of our service. Our team will measure and source matching high-quality glass (including custom sizes, Low-E coatings, tempered or laminated safety glass as required) to swap out failed units. We handle the removal of the old glass and install the new unit with precision, including renewing the edge seals and gaskets. The result is a clear, condensation-free view and restored thermal performance.

Skylight and Overhead Glazing Care

Skylights, glass canopies, and atriums add beauty and light to a space, but they require specialized care to stay leak-free. We provide maintenance and repairs for all types of overhead glazing. This includes cleaning skylight seals and weep channels, re-sealing around skylight frames and curb flashings, and replacing any brittle gaskets or cracked panes. Even a small skylight leak can lead to significant interior damage if not corrected, so we treat these issues with urgency. Our technicians have the equipment and training to work safely at heights to service roof glazing.

Custom Glazing Solutions

We thrive on solving hard-to-solve glazing problems. Our team is comfortable inspecting and repairing custom architectural glass installations, including very large or uniquely shaped panels that other companies might shy away from. We will assess the issue comprehensively and devise a fix that preserves the design intent while restoring functionality. Sentinel’s culture of craftsmanship and problem-solving means we approach each custom project with care and ingenuity, rather than forcing a cookie-cutter solution. If you have been told your glazing problem is “too complicated” or requires complete replacement, give us a call.

Vancouver Expert Glazing Services for Strata, Homes and Commercial Buildings

Managing a building with persistent window leaks or failed seals can be frustrating. Our team specializes in solving complex glazing issues, often the kind that other contractors have been unable to resolve. We bring together experienced, union-trained glaziers and advanced repair techniques to restore the integrity of your glass installations. Whether you oversee a multi-story condominium, own a custom-built home, or manage a commercial facility, we deliver tailored solutions that preserve your property’s design and improve its performance.

Strata and Multi-Residential Buildings

High-rise condominiums and townhome complexes present unique challenges for windows and glass facades. Over time, heavy rain, high winds, and building movement can all lead to water intrusion, foggy sealed units, or drafts that upset residents’ comfort. We work closely with strata councils and property managers to diagnose these problems in detail and implement long-term fixes. Our experts have resolved “leaky condo” issues by identifying root causes (such as aging window gaskets or insufficient flashing) and installing custom retrofits to stop the leaks for good. All work is planned to minimize disruption for residents: we coordinate repairs and replacements efficiently, keep the work area clean, and ensure safety protocols are followed at every step. The result is a healthier, more efficient building envelope that preserves your property value and keeps residents comfortable and dry.

Commercial Properties and Special Projects

Office towers, retail storefronts, and public buildings rely on extensive glass installations to create bright, inviting spaces. When something goes wrong, such as a leaking atrium skylight in a shopping center or a cracked curtain wall panel on an office high-rise, it can pose safety risks and disrupt business. We partner with building owners, facility managers, and engineers to fix these issues quickly and correctly. Our technicians are experienced in working on active commercial sites and occupied buildings. This means we can schedule repairs during off-peak hours or in phases, allowing businesses to continue operating with minimal disturbance. We tackle complex projects such as replacing failed glazing units high above street level, resealing glass curtain walls, or reinforcing aging glass structures for earthquake safety. With each project, we emphasize clear communication and meticulous workmanship. Businesses and public institutions throughout Metro Vancouver trust us to resolve critical glazing problems while upholding the aesthetic and safety standards their properties require.

Custom Homes

In custom homes, expansive glass features are often a centrepiece of the architecture. Floor-to-ceiling view windows, glass-walled sunrooms, and custom skylights fill these homes with light and stunning views. However, they can also develop issues over time, whether it’s a skylight that begins to drip during winter rains or a massive picture window that fogs up inside because its seal has failed. We address these problems without compromising your home’s character. Our team can carefully retrofit or reseal problematic windows and skylights so they perform like new, all while preserving their original appearance. If your modern West Coast house features an all-glass wall that’s letting in drafts, we will engineer a solution to tighten the seals and improve energy efficiency. Every home is unique, so we provide personalized assessments and transparent recommendations, ensuring you understand the options to protect and enhance your investment.

Annual Glazing Maintenance Packages

For clients seeking ongoing peace of mind, we offer annual service packages that include scheduled preventive maintenance for your glazing assets. Instead of waiting for leaks or failures to occur, these plans keep your windows and glass installations in top condition year-round. Regular maintenance not only addresses visible issues but also catches hidden problems early. In fact, routine inspections and maintenance of seals, caulking, and drainage systems significantly reduce the risk of leaks and other failures. By investing in a maintenance plan, building owners and managers can avoid costly emergency repairs and extend the life of expensive glazing systems.

All our maintenance plans are carried out by the same skilled glaziers who handle our complex repair projects, ensuring that no detail will be overlooked. We also ensure clear communication with property managers or homeowners. You will know exactly what work is being done each visit and why. Ultimately, our goal is to prevent headaches and protect your investment through diligent care

Scheduled Inspections

One of our experienced glazing professionals will inspect all accessible windows, doors, skylights, and curtain wall sections on a regular interval (typically annually, with semi-annual check-ups for very large or high-exposure buildings). We look for signs of wear such as cracked caulking, loose gaskets, fogging between panes, corrosion on frames, clogged drainage weep holes, and hardware issues. A detailed report is provided after each inspection, noting any findings and recommended actions.

Preventive Maintenance Work

During the service visits, we perform on-the-spot maintenance to address any minor issues before they escalate. This can include re-caulking small gaps, tightening screws or fasteners, lubricating window operators and door closers, cleaning out dirt and debris from window tracks and drain channels, and replacing worn weatherstripping. These small tasks, done proactively, ensure your windows and doors continue to perform optimally and seal out the elements.

Priority Repairs

If an inspection reveals conditions that require more than routine service, we provide a clear summary of the issue, the cause, and the recommended corrective work. Examples include failed insulated glass units, deteriorated perimeter sealant on exposed elevations, or hardware that no longer operates as intended. Our project coordinator will review each item with you, outline the repair method, and schedule the work at a suitable time. Maintenance program clients receive priority access to our service calendar, ensuring their properties are attended to promptly by the same team familiar with the site.

Documentation and Planning

Each year, you will receive documentation of the maintenance performed and the condition of your glazing systems. This helps with long-term capital planning and budgeting. (For strata properties, our reports can assist the strata council in demonstrating that they are meeting their duty to maintain the common property.) Over time, our maintenance program can inform you when certain components are reaching the end of their life, allowing you to plan replacements in a cost-effective manner rather than facing sudden failures. Planning for annual window maintenance is considered a best practice for multi-family buildings, and we make it easy by keeping you informed and ahead of potential issues.

Schedule an Initial Assessment

Arrange a site visit with our glazing specialists to review your existing windows, doors, skylights, and curtain walls. We will document current conditions, identify maintenance priorities, and prepare a clear plan outlining both immediate and long-term recommendations.

Testimonials

Client Feedback and Long-Term Partnerships

Our work often begins with a single repair or assessment and develops into an ongoing partnership built on consistency and trust. Many of our clients — property managers, homeowners, and business operators — continue to rely on us for their glazing maintenance year after year. Their feedback reflects the professionalism and care our team brings to every project, from routine inspections to complex remedial work.

Each testimonial represents a real project completed by our experienced glaziers in Metro Vancouver. We take pride in clear communication, reliable scheduling, and workmanship that meets the standard expected from a professional glazing contractor.

These experiences demonstrate what we value most: dependable results, respectful collaboration, and glazing systems that continue to perform well long after the work is complete.

“At Capilano, we had long-standing curtain wall issues across three buildings that had gone through multiple rounds of repairs over the years, with limited success. Sentinel Glass approached the problem differently. Their team was thorough in their investigation — reviewing sealants, connections, and past repairs to pinpoint the root cause. From their initial site work, they produced a detailed, methodical analysis of the system’s failures. Their diagnosis was thoughtful, evidence-based, and clearly rooted in technical expertise. In fact, the level of detail in their report exceeded what I’d typically expect even from a building envelope consultant. We had their findings reviewed by a third-party consultant, who agreed with Sentinel’s recommended approach.

Execution on-site was equally professional. They were responsive, transparent, and easy to coordinate with — both with our internal team and our tenants. Communication was proactive, and the schedule was clearly communicated and adhered to. Post-repair testing confirmed the fix was effective, and the building has remained dry since, with no recurring issues.

We’ve since worked with Sentinel on another curtain wall issue at a high-rise mixed-use building in Burnaby. Despite already having reports from two other consultants, their team identified additional issues that others had missed. Their attention to detail and technical insight set them apart. They’re not just an above-average glazing contractor — the Sentinel team are true specialists in diagnosing and resolving persistent building envelope problems. It’s been a pleasure working with the Sentinel team.”

“Our tower is made up of both residences in the tower, as well as connected to a commercial space. On the third floor of the tower there is a pool area with a large pony wall window assembly. This wall is also connected to the roof of the commercial space beside. After multiple complaints by the commercial tenants of water ingress, the strata council decided to investigate only to discover large amounts of water in the pony wall. Since this pony wall was also the base to a large window assembly, and the water had already damaged the steel studs, we found ourselves in a somewhat urgent situation.

Sentinel Glass came to our rescue with the glass wall by recognizing the issues right away and were willing to arrange their schedule to service us in a timely manner. They provided a detailed quote, did a presentation to the owners, and were able to begin the project within a few months. Dates and timelines were completely adhered to, materials were delivered when scheduled, and the site was always kept extremely clean.

To say that we would recommend Sentinel Glass and their team is obvious. In our industry, it is difficult to find companies that care about their clients, and who take the extra time and energy to do the right thing, not taking the easy way out, especially when dealing with a strata corporation and a 30-year-old building.”
