Each installation includes personalized color and texture selection to match your home's architectural style while maintaining structural integrity.
Soffit Repair
We provide comprehensive soffit repair and installation services that enhance roof ventilation while protecting against moisture damage.

Each project includes proper sizing and placement to ensure optimal airflow and weather resistance for long-term performance.
Eavestrough Services
Our eavestrough installation and repair services protect foundations from water damage using durable aluminum materials. We ensure proper slope and downspout placement to direct rainwater away from structures. Optional leaf guard systems prevent clogs while maintaining efficient drainage for residential properties in varying weather conditions.

Our selection includes traditional and contemporary designs with durable finishes that withstand Canadian weather. Each installation incorporates proper insulation and hardware for smooth operation and enhanced property value through improved curb appeal.

Custom beam wraps conceal structural supports while enhancing exterior aesthetics. We fabricate these decorative elements from weather-resistant aluminum to match home exteriors. The installation process ensures secure attachment without compromising structural integrity, providing both functional protection and visual enhancement for residential properties.
Questions
What causes damage to siding?
Harsh weather conditions, UV exposure, physical impacts, insect infestations, and improper installation can all contribute to siding damage over time.
How do I know when to replace my siding?
Look for cracks, warping, fading, water damage, increased energy costs, or pest activity as indicators that replacement may be necessary.
Why should I re-side my home?
Re-siding improves curb appeal, enhances energy efficiency, increases property value, and provides better protection against weather elements.
Does all my siding need replacement at once?
Partial replacement is possible for localized damage, but full replacement often ensures uniform appearance and comprehensive protection for aging installations.
What's the best siding material for my home?
Material selection depends on durability needs, aesthetic preferences, and maintenance requirements - options include aluminum, fiber cement, steel, and vinyl.

My wife and I were looking to get all new siding, fascia,soffit and eaves done. We had a few quotes but Bruce at Custom aluminum seemed to be the best. We had a quote done on August 11. We were told it would be at least a couple months before they could start. We didnt hear anything from custom aluminum after that. We reached out to Bruce mid October and we were told the siding was on back order do to Covid and it was hard to get products which is completely understandable. However nobody from Custom aluminum picked up the phone to even let us know what the current situation was and left us

Custom Aluminum recently replaced the entire gutter system of our house - eavestroughs, soffits, fascia, down spouts, et al - and they did an outstanding job. From the very start their sales rep, Dave, offering valuable tips and info, suggested the best aluminum colour to match those of our house; and yes, it turned out to be just perfect. The installation process by Ibrahim and his assistants Istref and Arjiet was impeccable. Not only were they knowledgeable and experienced, but their work ethics, their overall attitude and their excellent disposition for service were impressive and admirable

Custom Aluminum was a pleasure to work with. Dave in sales was very knowledgeable and always available to answer questions both before and after placing our order. The office staff always kept us aware of the installer schedules - something we did not expect to see. Kevin and Steve were FANTASTIC installers - very professional, personable and detailed work from this installation team. They also provided good recommendations and advice as they were installing to make the work even better! I would recommend Custom Aluminum to all looking for this type of work.

I highly recommend Custom Aluminum Windows & Siding! We needed to change eavestroughs/facia/soffit and also wanted to add exterior insulation and new siding to our family home (built in 1970s). We got around 9 different quotes, and by far one of the most competitive and fair was by Custom Aluminum. The products they use are excellent, and they explain and show you the difference. The owner is incredibly patient and explained everything to us, throughout the job he was always available to answer questions. Then the Superstar team (Kevin and Steve), came to our home and did a fantastic job! They

We had Custom Aluminum renovate the exterior of our house with new insulation, aluminum siding and eaves. The quality of work was excellent and the crew showed up everyday. Less than a year later I made a service call. The new crew was rude, threatening and unprofessional. They argued that the service was covered under warranty. I would not recommend this company because of that experience.
