“Walt Windows and Doors replaced our old drafty front door with a bespoke Palladio composite door and side panels in Dublin 15. The difference in warmth and soundproofing is remarkable. The installation crew was on time, super neat, and left our hallway spotless. Couldn't recommend them higher!”
“We had all back windows and sliding patio doors upgraded to triple glazing by Walt Windows and Doors. Transparent pricing from the initial home survey, zero pushy sales, and top-tier craftsmanship. The house is noticeably warmer and our heating bills are already down.”
“Top notch craftsmanship from the team at Walt. They replaced 8 casement windows and a front entrance door in our home. Millimeter precision fitting and great customer service from start to finish. The 10-year warranty gives genuine peace of mind.”
“Delighted with our new composite entrance door. We used their door configurator first, then booked a site survey. Polite fitters, zero draft, solid 5-point locking mechanism, and they finished everything in one morning. 5 stars all the way!”
“Excellent experience dealing with Walt Windows and Doors at Plato Business Park. Needed high-spec glazing and heavy-duty secure locks. Fast turnaround, great communication, and faultless execution. Will definitely use them again for our next unit.”
“Superb job replacing all windows and external patio doors in our semi-detached home. The draft elimination is incredible. Clean, professional tradesmen who treated our home with total respect. Thank you to the whole Walt team!”
