Good aluminum windows can still perform badly if they are installed badly. A frame that is slightly out of level, a gap that is sealed poorly, or a sliding sash that is not adjusted can cause drafts, noise, dust and water problems for years.
That is why aluminum windows installation deserves as much attention as the windows themselves.
This guide explains how aluminum windows installation works step by step, what changes between a new build and a replacement, which conditions to consider in Saudi Arabia, and what to ask an installer before you sign.
Why Aluminum Windows Installation Quality Matters
An aluminum window is a system: frame, glass, seals, hardware and the joint between the frame and the wall. The installation touches almost every part of that system.
Poor aluminum windows installation commonly shows up as :
- Sashes that stick, rub or do not close fully
- Air or dust coming in around the frame
- Water marks around the edges after rain or cleaning
- Noise from loose fixings or poorly adjusted hardware
- Visible gaps or uneven finishing around the frame
Most of these are avoidable. They usually come from rushed measurement, poor preparation or skipped checks, not from the aluminum itself.
New Construction vs Window Replacement
The aluminum windows installation process differs depending on your situation.
New construction | Replacement | |
Opening | Often still rough, can be coordinated early | Existing opening, may be uneven or damaged |
Measurement | Taken from structural openings | Taken after checking the old frame and finishes |
Main risk | Openings not finished to the planned size | Damage to plaster, tiles or paint during removal |
Best time to plan | Before finishing work begins | Before ordering, after a site survey |
In a new build, agree on window types and sizes early so the openings are prepared correctly. In a replacement, a site survey matters even more for aluminum windows installation, because the old opening decides what is possible.
The Aluminum Windows Installation Process, Step by Step
1. Site survey and measurement
A professional visits the site and checks every opening. The surveyor looks at :
- Width and height at several points, since openings are rarely perfectly square
- Wall thickness and finishes
- Obstacles such as shutter boxes, curtain rails or AC units
- The condition of the opening if you are replacing windows
Measuring takes more care than it seems, and an error here can lead to remaking a window.
2. Choosing the window type and specification
Common aluminum window types include sliding, hinged (casement), fixed and folding systems.
The right one depends on the room, the opening size and how you want to ventilate. Also decide :
- Glazing: single, double or laminated glass, depending on your needs for insulation, noise and safety
- Frame finish and colour
- Thermal performance: ask whether the frame includes a thermal break
- Hardware: handles, locks and rollers
ATCE offers aluminum windows and doors with thermal insulation and custom designs. Ask for the specification in writing so everyone agrees on what is being installed.
3. Fabrication
The frames are made to the surveyed sizes. Made-to-measure fabrication is a major reason to survey carefully before aluminum windows installation begins. Fabricating in a factory also lets the frames be checked before they reach your site.
4. Preparing the opening
Before fitting, the opening should be :
- Clean and free of debris
- Checked for level and plumb
- Repaired if there are cracks, loose plaster or damaged edges
Skipping this step makes every later stage of aluminum windows installation harder.
5. Fitting and fixing the frame
The installer places the frame in the opening, checks that it is level, plumb and square, and fixes it securely to the structure. Small packers or shims are commonly used to hold the frame in the right position while it is fixed. The goal is a frame that is straight and firmly held, but not distorted by over-tightening.
6. Sealing the gap
The joint between the frame and the wall is a critical point. It must be filled and sealed properly to limit air, dust and moisture getting in. Ask what sealing materials and method the installer uses, and whether the seal is done inside, outside or both.
7. Glazing and hardware adjustment
If the glass is fitted on site, it is installed and secured. The installer then adjusts the sashes, rollers, handles and locks so everything opens, closes and locks smoothly.
8. Testing and quality check
A proper handover at the end of aluminum windows installation includes :
- Opening and closing every sash several times
- Checking the locks
- Checking the seals and finish around the frame
- Checking for scratches or damage on the glass and frame
- Confirming drainage openings are clear, where the system has them
9. Cleaning and handover
The installer removes protective film and debris, shows you how to operate and maintain the windows, and explains what warranty applies, if any. Ask for this in writing.
Conditions to Consider in Saudi Arabia
Saudi conditions add extra demands to any aluminum windows installation.
Heat and cooling load. Windows are a significant place where heat enters a building. In a country with heavy air conditioning use, glazing and frame specification matter. Ask the supplier about thermal-break frames and double glazing for your project.
Dust and sand. Fine dust can settle on tracks and get through poorly sealed joints. Good seals and a well-sealed frame joint help. Keep sliding tracks clean so the sashes keep moving smoothly.
Sunlight and finish. Strong sun can be hard on finishes over time. Ask about the coating or finish used on the frames and what is recommended for exterior use.
Villas and large openings. Villas often have large glazed areas. Large sashes need good rollers, accurate fitting and careful handling.
Building and community requirements. Requirements can vary by project, building type and location. Check with your consultant, developer or the relevant authority instead of assuming.
Common Aluminum Windows Installation Mistakes to Avoid
- Measuring once, quickly, and ordering based on that
- Ignoring that walls and openings are not perfectly square
- Fitting before the opening is repaired or cleaned
- Over-tightening fixings and distorting the frame
- Using a weak or incomplete seal around the frame
- Not adjusting the hardware after fitting
- Skipping a final check before the installers leave
How to Choose an Aluminum Windows Installer
Use this checklist when comparing offers for aluminum windows installation :
- Do they survey and measure on site before quoting a final price?
- Is fabrication done in their own factory, or is it outsourced?
- Do they install themselves, or use subcontractors?
- What exactly is included: glass, hardware, sealing, cleaning, removal of old windows?
- What finish and thermal specification is offered?
- What does the warranty cover, and for how long? Ask for it in writing.
- Can they show completed projects similar to yours?
Be careful with quotes that are much cheaper than the rest without a clear explanation. Often something has been left out of the scope.
What Affects the Time and Cost of Aluminum Windows Installation
Neither can be given honestly as a single number, because both depend on your project. The main factors are :
- Number and size of windows
- Window type and glass specification
- Frame finish and colour
- Whether old windows must be removed
- Condition of the openings
- Access to the site and the floor level
- Any finishing work needed afterward
Request a written quote based on a site survey, and ask for the timeline in your quote.
Maintenance After Aluminum Windows Installation
- Clean the frames and glass with mild soap and water
- Keep sliding tracks and drainage slots free of dust and sand
- Check seals and hardware occasionally
- Avoid harsh abrasive cleaners that can damage the finish
- Call the installer early if a sash starts rubbing or a lock stops working

Frequently Asked Questions
What is aluminum windows installation?
It is the process of fitting aluminum window frames into wall openings, fixing them securely, sealing the joints, installing glass and hardware, and testing that everything works properly.
How long does aluminum windows installation take?
It depends on the number and size of windows, site conditions and whether old windows are being removed. Ask your installer for a timeline based on your actual project.
How much does aluminum windows installation cost in Saudi Arabia?
The price depends on the size, type, glass, finish, number of windows and site conditions. A reliable quote needs a site survey.
Can I install aluminum windows myself?
It is not recommended for most homeowners. Accurate measurement, levelling, fixing and sealing are all skills that affect how the window performs, and larger windows are heavy and need careful handling.
Do I need to remove my old windows first?
In a replacement, yes, the old frames are removed and the opening is prepared. Ask your installer whether removal and disposal are included in the price.
Are aluminum windows suitable for the Saudi climate?
They are widely used in Saudi Arabia. Performance depends on the specification: thermal break, glazing, seals and finish. Ask the supplier what they recommend for your location.
How do I know if the installation was done properly?
The window should open and close smoothly, lock securely, sit straight in the frame, and show no visible gaps or damage. Check these before the installers leave.
What maintenance do aluminum windows need?
Regular cleaning, keeping the tracks clear of dust and sand, and checking seals and hardware from time to time.
