Installing a sectional concrete garage is much quicker than constructing a traditional masonry building, but the site must be properly prepared before the fitting team arrives.
From checking the concrete base to keeping access routes clear, this guide explains what normally happens before, during and after installation day.
Finalise the Garage Specification
The garage should be fully specified before it is manufactured. This includes its external dimensions, roof style, wall finish, garage door, personnel doors, windows, guttering and other features.
Changing the position of a door or window after the panels have been made may not be straightforward. Consider how you will move around the garage, where storage will be positioned and how vehicles will approach the main entrance.
Dencroft manufactures a range of sectional concrete garages, including single, double, pent, apex and extra-height designs.
Make Sure the Base Is Ready
A strong, level concrete base is essential. The panels, roof and doors rely on accurate dimensions and levels to align correctly.
The base must:
- Match the dimensions specified for the garage
- Be level and square
- Have suitable drainage around it
- Be free from loose material and standing water
- Have cured sufficiently before installation
An existing base does not necessarily need replacing because it has a minor surface crack. Its overall condition, dimensions, level and ability to support the new building should be assessed first.
Dencroft provides a garage base laying service that can include excavation, groundwork, removal of an old base and preparation of a new one.
Remove the Existing Garage Safely
If an old garage occupies the site, it must normally be dismantled and removed before the replacement can be installed. This work should be scheduled early enough for any required base repairs or replacement to be completed.
Older garages may contain asbestos cement roof sheets. Suspected asbestos should be assessed before demolition and must not be drilled, broken or handled as ordinary waste.
Dencroft can assess an existing building during the survey and discuss removal, asbestos disposal and base preparation as part of its garage installation process.
Clear the Delivery and Working Area
The installation team needs a safe route between the delivery vehicle and the garage base. Before the agreed date:
- Move vehicles away from the driveway and working area
- Unlock gates and remove temporary obstacles
- Clear tools, bins, garden furniture and loose materials
- Trim back overhanging vegetation where necessary
- Keep children and pets away from the site
- Tell the installer about restricted access or underground services
Do not assume that panels can be carried through a narrow passage or over a wall. Any access restrictions should be discussed during the survey so that the delivery and installation method can be planned properly.
What Happens During Installation?
Sectional concrete garages are manufactured before delivery and assembled on the prepared base. The exact sequence depends on the model and specification, but installation will generally involve:
- Checking the base and agreed position
- Positioning the foundation units or first wall sections
- Erecting and securing the reinforced concrete panels
- Installing the roof trusses and roof covering
- Fitting the main garage door, personnel doors and windows
- Adding fascias, guttering and finishing components
- Checking alignment, operation and the completed specification
The concrete panels and roofing components are heavy and require appropriate handling methods. A sectional garage should therefore be erected by a trained installation team rather than approached as an ordinary DIY building.
How Long Does Installation Take?
Sectional construction allows the garage to be assembled efficiently, but there is no single installation time for every project.
The programme can be affected by:
- The size and complexity of the building
- The number and type of doors and windows
- Site access
- Roof and finish choices
- The condition of the base
- Weather and safe working conditions
The estimated installation time should be confirmed when the project is booked. Base preparation and garage installation may take place on different dates to allow the concrete to cure properly.
What If the Weather Is Poor?
Light rain does not necessarily prevent a sectional garage from being installed. However, strong winds, heavy rain, ice or other unsafe conditions can affect the handling of large panels and roof sheets.
The installation team will decide whether work can proceed safely. Avoid making arrangements that depend on completion at a precise hour, particularly during unsettled weather.
Check the Garage at Handover
Once installation is complete, take time to inspect the building with the fitting team. Check that:
- The garage matches the agreed dimensions and specification
- Doors and windows open, close and lock correctly
- Roofing, fascias and guttering are securely fitted
- Rainwater is directed to the intended drainage point
- Any optional features have been installed
- You understand the maintenance and guarantee conditions
Ask how to operate and maintain the doors, locks and other moving components. Any concerns should be raised before the fitting team leaves or reported promptly afterwards.
Plan Your Concrete Garage Installation
Successful installation starts well before delivery day. Accurate measurements, a suitable concrete base, clear access and an agreed specification all help the work proceed smoothly.
