At TSL Construction, we specialize in the design, fabrication, and installation of all types of aluminium windows. Whether you’re building a new home, upgrading an office space, or renovating a commercial property, our aluminium window frames offer the perfect balance of strength, style, and long-lasting performance.
Every window we produce is fully customizable — from frame design to color — thanks to our in-house powder coating process that guarantees a permanent, factory-quality finish.
we don’t just build strong aluminium frames — we complete every window with premium, approved-quality accessories to ensure smooth operation, long-term durability, and enhanced security for your home or business.
We source only trusted, industry-approved hardware components, so every window we install performs reliably for years to come.
Every window begins in our controlled factory environment, where our skilled technicians fabricate each frame with precision engineering and strict quality checks at every stage. From cutting and joining to powder coating and hardware fitting, our team ensures each unit meets exact specifications before it ever leaves the factory floor.
Once fabrication is complete, we take extra care to protect your windows during transport. Our team uses secure packaging and safe handling procedures to ensure every unit arrives at your site in perfect condition — free from damage, scratches, or misalignment.
Our work doesn't end at delivery. Our experienced installation team fits each window with precision, ensuring proper alignment, sealing, and function. Once installed, we carry out a thorough snagging process — inspecting every window for any imperfections or issues — so that what we hand over is completed to the highest standard.
We specialize in a wide range of construction services, including residential, commercial, and industrial projects. From initial design to final inspection, we work closely with our clients to understand their unique needs and vision.
Our technicians visit your site for precise measurements and provide a detailed quote at no cost. Once agreed, we formalize the project with a signed contract.
We source and prepare all materials before commencing fabrication, typically completed within two weeks. Timelines may vary depending on the scope of work.
Completed materials are delivered directly to site and installation begins immediately. We finish with thorough checks and making good to ensure a clean, quality result.
