Modern low-rise office building with full-height aluminium glazing under an overcast sky

Commercial

Commercial windows and doors, factory-direct from Reading

Offices, retail, rental property and developments — manufactured in-house, installed by our own teams, delivered on programme.

Why S.E.A

What factory-direct means for your project

Lead times you can plan around

Frames are made in our own Reading factory, so programme dates depend on us — not a third-party supplier's queue.

Specified to your project

No one-size-fits-all. We tailor systems, glazing and finishes to the building and the budget.

One accountable team

Our own surveyors and installers from start to finish — one point of contact, deadlines met.

Systems & partners

Proven systems, manufactured in-house

We build on commercial-grade profile systems from established names — aluminium from Monarch and Sapa with partner profiles from Cortizo, and uPVC from Spectus — covering windows, doors, bifolds and entrances.

  • Aluminium & uPVC windows and doors
  • Composite and bifold options
  • Security and efficiency to modern standards
