Another 5 star review for NexGen Windows

"They cut the damaged wall under the window making the space for the new door and window. They take a lot of care to avoid dust and clean everything to finally install the door. Other chaps plastered the surfaces and installed the couple of tiles to obtain a 100% satisfaction work. Everything was smooth and the result is awesome."
