    What they say...

    «I ordered windows to the living room and bedroom. Service they provided was great and on a high level. Unfortunately, I had rather low budget but they managed to find a good variant! So the price-quality relationship is perfect. If I plan to change windows in my second house, I certainly will turn to Custom Sunroom».

    Kristina Johnson

    «I was looking forward to different glazing variants of my balcony and chose Custom Sunroom. I am really grateful to the installer’s team. These guys are truly professional. They answered politely to all my questions and made their job very quickly. In general I am pleased with the service and the quality of windows».

    Jaan Kreisberg

    «I and my husband decided to order new windows and doors at CustomSunroom and were absolutely satisfied! The windows are very beautiful and stylish and the doors are of the very color I dreamed about! What’s more they’ve done all installations quickly. I’m totally delighted! It is great company. I give it five stars!»

    Maria Shannon

    «I never thought that it is possible to replace the interior door so quickly. After my call to «Customsunroom», only 3 days passed before i`ve removed the membrane from the new installed door! They work very quickly, and most importantly, professionally and cleanly».
