Proudly Local.
Made-to-Measure.
Engineered for Real Living.

Sequ-Door is a proudly South African manufacturer. Founded in 2007 and headquartered in Meyerton, Gauteng. Your product is manufactured and installed by our own teams. Nothing is subcontracted, and nothing is off-the-shelf. 

That control over the full process, from design consultation through to the final fitting is how we deliver consistent quality, accurate lead times, and finished installations our customers are happy to recommend. Whether you are upgrading a single window or kitting out a new build, the same standards apply.

About Us

Why Choose Sequ-Door

Six reasons our customers keep choosing us and keep referring us. 

Expertly Trained Staff

From sales consultants to installers, every team member is trained on the full Sequ-Door product range. The person who quotes your project understands exactly what we manufacture, how it installs, and how it performs over time.

Warranties You Can Trust

Every product line carries a clear, written warranty. Our aluminium doors and windows are manufactured to AAAMSA standards. Our shutters carry up to ten years on aluminium profiles. Full warranty terms are available on our Warranty & Maintenance page.

100% Client Satisfaction

We measure success by repeat business and referrals. From the first site visit to after-sales support, our goal is to leave every client fully satisfied with the product, the installation, and the service.

Factory Supply & Export

We manufacture in-house at our Meyerton facility. As a SADC-registered exporter, we supply trade buyers and distributors across South Africa and into neighbouring SADC countries, with shorter lead times and better margins than imported alternatives.

Customisation

Nothing we sell is off-the-shelf. Sizes, configurations, colours, glass types, hardware, and finishes are all customisable. Standard ranges keep costs and lead times competitive; custom orders match the brief exactly.

Professional Advice

Our consultants give you straight answers. What fits your opening, what suits your budget, what performs in the South African climate, and what the trade-offs are. No upselling, no jargon.

What does Sequ-Door Stand For?

The name itself spells out how we work. Four letters, four principles, applied to every project we manufacture and install. 

S

Success

Success

From first enquiry to after-sales follow-up, every step is handled by our own people, never subcontracted. That is how we keep the experience consistent.

E

Excellence

Excellence

Every frame, every join, every fit. We pursue excellence in manufacturing, installation, and strive for exceptional customer experience throughout and after your project.

Q

Quality

Quality

We are accredited by AAAMSA and SAGGA, back every product with a written warranty, and build quality control into every step from material selection through to final inspection.

U

Uniqueness

Uniqueness

Every Sequ-Door project is custom-made. No two installations are identical because no two openings, briefs, or homes are identical.

Quick Facts

Four reasons Sequ-Door is trusted across South Africa and beyond. 

We Are AAAMSA & SAGGA Accredited

Sequ-Door is accredited by AAAMSA and SAGGA. Every aluminium door and window we make is built to their standards and site-specific certificates are available on request.

Proudly Made in South Africa

All our products are designed and manufactured locally, supporting South African industry, local jobs, and shorter, more reliable supply chains.

We Supply to Sub-Saharan Africa

As a SADC-registered exporter, we supply trade and distribution partners across SADC member countries. Importers from SADC countries pay little to no import duties on Sequ-Door products.

Established in 2007

Founded in 2007 long enough to have outlived our own warranties. When you are choosing a supplier you can still call in five or ten years, that matters.
