If you’re replacing windows in your Dublin home, you’ve probably got a lot of questions before you commit – how long will it take, what’s involved on the day, and will the whole thing be a headache? This guide covers the full Dako window installation process with Thermoglaze, from your first phone call to the moment the team packs up and leaves.
What Are Dako Windows?
Dako is a European window manufacturer with a proven track record for thermal performance, security and build quality. Thermoglaze Windows & Doors is an Irish partner of Dako, offering their systems across Dublin.
Key things to know about Dako windows:
- Security rated at Rc2 and Rc3 – independently tested resistance to break-in attempts
- High thermal insulation values – designed to reduce heat loss and cut heating costs
- Low maintenance frames – won’t need painting or regular upkeep
- Available in aluminium, timber and uPVC – so there is an option for most property types
- Wide colour range – including bespoke finishes, not just standard white or brown
Modern design that works on new builds and older Dublin homes alike
Step 1: Get in Touch and Request a Quote
Call the Thermoglaze team on 01 912 0600, use the contact form on their website or visit one of the showrooms.
When you first get in touch, have a rough idea of:
- How many windows you want replaced or installed
- What type of property you have
- Whether it’s a full renovation or a targeted replacement job
- Any preferences on style, colour, or glazing
If you haven’t worked everything out yet, don’t worry – the survey visit is where the detail gets nailed down.
Step 2: Home Survey and Technical Measurement
Once you’re ready to move forward, a member of the Thermoglaze team visits your home to carry out a proper survey. This usually takes one to two hours, depending on the size of the job.
During the survey, the surveyor will:
- Measure every window opening
- Check the condition of existing frames and surrounding walls
- Flag anything that needs attention – bay windows, arched openings, non-standard configurations
- Walk you through the available window configuration options for each room
- Confirm glazing type and energy specification
This is the right time to ask questions – before anything is ordered or manufactured.
Step 3: Choosing Your Windows
After the survey you’ll get a detailed quote. Once you’re happy to go ahead, you’ll confirm your window specifications. Dako windows are available in a range of styles to suit different Dublin homes:
- Casement windows – the standard choice for most Irish houses, available side-hung or top-hung
- Tilt & Turn windows – open inward two ways, easy to clean from inside, good for ventilation control
- Aluminium windows – slim sightlines, sharp finish, long service life
- Timber windows – a natural look suited to period properties and conservation areas
- uPVC windows – affordable, thermally efficient, and very low maintenance
You’ll also choose glazing type (double or triple), colour, hardware finish, and any extras like trickle vents or child restrictors.
Step 4: Manufacturing and Lead Times
Your Dako windows go into production once the order is confirmed – each one made to your exact measurements. There is a lead time, and the team will give you a clear indication of this upfront. You won’t need to do anything during this period. The Thermoglaze team will contact you once the windows are ready to book in the installation date.
Step 5: Preparing for Installation Day
A bit of preparation before the team arrives keeps the day moving:
- Move furniture, plants, and curtains away from each window
- Take down any blinds or internal shutters in advance
- Make sure there’s parking close to the property for the van
- Ensure every room where windows are being fitted is accessible
- If you have a burglar alarm with window sensors, let the team know beforehand
The team will tell you how many people will be on site and give you a time estimate for the job before they arrive.
Step 6: The Installation Process
Here’s what happens on the day:
Removing the Old Windows
The old windows are removed first. The team protects your floors and interior surfaces during the process.
Fitting the New Dako Frames
The new frames are placed in the openings, levelled, packed and secured to the surrounding structure
. Getting the fit right at this stage matters for air tightness and long-term performance.
Glazing and Sealing
Once the frames are fixed in place, the glazed units go in. The team seals around the frames inside and out using professional-grade sealant to block draughts and stop water getting in.
Finishing Touches
Internal gaps are made good. Window boards, beads, and trims are fitted. Handles, locks, and restrictors are tested and adjusted until everything operates as it should.
Step 7: Post-Installation Walkthrough
Before leaving, the team will walk you through the completed work. You should:
- Open, close, and lock every window to check it operates correctly
- Inspect the finish around the frames inside and out
- Ask how to operate any tilt-and-turn function or child restrictors
- Confirm warranty details before the team leaves
Dako windows carry a manufacturer’s warranty and the Thermoglaze installation is backed directly by the company. If you spot anything after the team has gone, call 01 912 0600 and it will be sorted.
Could You Qualify for an SEAI Grant?
If you’re replacing single-glazed windows with a thermally upgraded option, you may be eligible for the SEAI home energy upgrade grant. The Sustainable Energy Authority of Ireland runs grants for homeowners doing qualifying energy upgrades – and window replacement can qualify.
Raise this early in the process, before the order is confirmed, as it can affect which specification you choose. The Thermoglaze team can advise on whether your project is likely to be eligible.
New Builds and Replacement Projects
Thermoglaze handles both new build projects and replacement projects across Dublin. Whether you’re fitting windows into a new self-build or finally replacing the original frames on a 1970s semi-d, the process is the same – survey, specification, manufacture, install.
If you’re working with an architect or building contractor, Thermoglaze can liaise with your project team directly and coordinate around the site programme.

FAQs
1. How long does a Dako window installation take in Dublin?
For a typical semi-detached home with 8–10 windows, one full day is usually enough. Larger properties or more complex jobs may need two days. You’ll get an accurate estimate after the survey.
2. Do I need to be at home during the installation?
Yes. The team needs access to every room, and you’ll want to be there for the final walkthrough before they leave.
3. Will the installation be noisy or messy?
There will be noise while old frames come out and new ones go in. The team protects floors and surfaces and cleans up before leaving, but plan for some disruption on the day.
4. Can Dako windows be fitted in period properties?
Yes. Dako windows are available in styles and finishes that suit older homes. If you’re in a conservation area or subject to planning conditions, the team can advise on the right options.
5. What is the difference between Rc2 and Rc3 security ratings?
Rc2 means the window withstands a break-in attempt using basic tools for around 3 minutes. Rc3 resists a more determined attack with heavier tools for longer. Both are a big step up from older standard windows.
6. Are Dako windows energy efficient?
Yes. They’re built to high thermal insulation standards. Depending on the specification, they can noticeably reduce heat loss. Triple glazing is available if you want maximum thermal performance.
7. Can I get the SEAI grant when replacing windows with Dako?
You may be eligible for the SEAI home energy upgrade grant if you’re replacing single-glazed windows with a qualifying energy-efficient option. Ask the team about this before you confirm your order.
8. What if I notice a problem after installation?
Call Thermoglaze on 01 912 0600. Dako windows carry a manufacturer’s warranty and the installation is covered by Thermoglaze directly. Report anything promptly and it will be dealt with.
9. Do you install Dako doors as well?
Yes. Thermoglaze also installs Dako doors, including entrance doors and garage doors. If you’re replacing windows and doors at the same time, the team can handle both together.
