There is no shortage of options when you search for a window company in Cork. The question is how you tell a good one from the rest.
Some companies sell windows but subcontract the fitting. Some cannot tell you who manufactures the products they install. Some offer a guarantee that disappears the moment you need to use it.
Cork homeowners come to Energy Glazing for specific reasons. This page sets out what those reasons are so you can decide for yourself.
Over 30 Years Fitting Windows Across Cork
Energy Glazing has been in business since 1993.
That is over 30 years of measuring, fitting, and finishing windows and doors in Cork city and county. Semi-detached houses in Ballincollig. Period terraces in Sunday’s Well. New builds in Carrigaline. Renovations in Midleton.
We know Cork properties. We know what the coastal weather does to frames, seals, and finishes over time. And we have a track record that spans three decades, not three years.
When you are spending a significant amount on your home, the age of a company matters. Young companies come and go. A business that has been serving the same county since 1993 has stayed around for a reason.
We Supply Direct From the Manufacturer
This is a distinction that matters more than most homeowners realise.
Energy Glazing is a direct supplier. We source our windows from named manufacturers including Reynaers, Schuco Jansen, Spectus, Sky-Frame, and KCC Group. We do not buy through a middleman and pass the markup on to you.
When you buy direct from the manufacturer, several things improve. Product knowledge is better. Lead times are more reliable. And accountability is clearer. If there is ever a product issue, we go directly to the manufacturer. There is no third party to blame and no runaround.
You can read more about our product range and supplier relationships on our window company Cork page.
One Team Handles Everything
Supply and installation under one roof.
Energy Glazing does not sell you windows and then hand the fitting over to a subcontracted team. Our own fitters carry out every installation. That means one company is responsible for the entire job from the survey through to the final clean.
This matters when something needs attention. There is no grey area about who is responsible. We supplied it, we fitted it, and we stand behind it.
A 10-Year Installation Warranty
We offer a 10-year warranty on all our installations.
That covers the workmanship as well as the product. If something is not right with the fitting in that period, we come back and sort it. No arguments, no quibbling over whose fault it is.
Ask any window company you are considering for the specific terms of their workmanship guarantee. Ask whether it is insurance-backed. An insurance-backed guarantee protects you even if the company closes down. It is worth asking about specifically.
SEAI Registered and Grant-Ready
Energy Glazing is a registered SEAI contractor.
That means if you are replacing windows in an existing home, you may be eligible for an SEAI grant and we can manage the application on your behalf. The grant is deducted directly from your invoice. You do not need to chase paperwork or deal with the SEAI yourself.
Not all window companies in Cork hold SEAI registration. If the company you are considering cannot confirm their registration, they cannot process your grant.
Full details on eligibility and the application process are on our SEAI grants page.
129 Five-Star Google Reviews
We have over 129 five-star reviews on Google.
That is not a number you build overnight. It comes from consistently showing up on time, doing the job properly, and leaving the site clean. Read through the reviews and you will see the same things mentioned again and again. Tidy workmanship, good communication, no surprises on the day.
Before you hire any window company in Cork, check their Google reviews. Look at the number, not just the rating. And read a few in detail. Anyone can have one good review. Consistent feedback over 125 jobs is a different thing entirely.
A Full Range of Windows and Doors
We cover the full range of residential windows and doors.
On the windows side, we supply and install casement windows, alu-clad windows, sliding sash windows, and tilt and turn windows across Cork.
On the doors side, we cover composite doors, patio doors, French doors, lift and slide doors, and folding doors.
We also install conservatories across Cork for homeowners looking to add a new room to their property.
A company with a narrow range will steer you towards what they carry. We let the product suit the home, not the other way around.
We Cover Cork City and County
Our team works across Cork city and the wider county.
Carrigaline, Midleton, Ballincollig, Mallow, Bandon, Cobh. If you are in Cork, we cover your area. Confirm at the survey stage and we will tell you the lead times and logistics for your location.
Free Survey, Written Quote, No Obligation
We offer a free home survey before providing any quote.
A proper survey means we measure your openings accurately, identify any access challenges, and advise on the right product for your home. The quote we produce is written, itemised, and covers everything including removal and disposal of old frames.
There is no obligation to proceed. If you want to compare our quote against others, go ahead. We are confident in what we offer.
