When this customer contacted us about replacing their old garage door, they were hoping for a clean, modern upgrade that would give them easier access and better security. What they didn’t realise at first was that the existing opening wasn’t structurally suitable for the wider, more practical garage door they wanted. Before we could install their new door, we needed to fit an RSJ (Rolled Steel Joist) to support the load above the opening.

Most garage door installers would have stopped there — advising the customer to find a separate builder, delaying the project, and increasing costs. But at Hemsure Garage Doors, we specialise in the full package. Our team is qualified to undertake the structural alterations, building work and customisation required to ensure every installation is safe, compliant, and perfectly fitted.

A Seamless Structural Upgrade

After assessing the garage structure, we removed the old lintel and installed a new RSJ tailored to the required span. This ensured:

  • Proper load-bearing support

  • Compliance with building control requirements

  • A wider, more usable opening for the customer

  • A long-term, future-proof installation

With the RSJ in place, we completed the brickwork, sealed the structural opening, and prepared everything ready for the new door.

The New Door Installation

Once the structural work was complete, we installed the customer’s chosen garage door — a sleek, secure, and low-maintenance option that instantly modernised the home’s exterior. The wider, reinforced opening made access easier and increased usable driveway space.

The customer was delighted that everything could be handled by one company, without the usual hassle of having to bring in extra trades.

Why Our Building Capability Sets Us Apart

Most companies simply install garage doors. We go further.

Because we can carry out building alterations, RSJ installations, custom openings, brickwork changes, height adjustments, lintel replacements, and structural modifications, we’re able to deliver solutions that other companies can’t. This makes us ideal for:

  • Converting two single doors into one large double door

  • Increasing door height for 4x4s, caravans or work vans

  • Widening openings to improve access

  • Replacing undersized or failing lintels

  • Creating completely new garage entrances

This “all-in-one” service is what truly marks Hemsure out from a standard garage door installer — we can adapt your garage to suit the door, rather than limiting your choice to what already fits.

Thinking of Upgrading Your Garage?

Whether your installation is straightforward or needs structural changes, we can help design and deliver the perfect solution. From RSJs to brickwork, from roller doors to sectional doors, our team handles everything safely, professionally, and efficiently.
