What our customers say

“Reflex just installed a new porch, front door, side panel with cat flap, and renewed the front soffits and facias, we used them before for the whole house and all were done professionally and on time, thoroughly recommend the service and the product! Very friendly, no pressure sales team.”

“Front door fitted today and very pleased with the result. Great communication from them from initial contact to arranging fitting. Door looks great and was cheaper than all other local companies for the equivalent door. Would highly recommend.”

“First class service from start to finish, great communication and very reasonably priced. The new windows and doors look outstanding and the installation team were great. They warned us in advance that there may be some damage, particularly bathroom tiles depending on how the original windows were installed but they did brilliantly and there was no damage at all."

“Highly recommend this company. The service is very professional and they can cater for all your needs no matter how big or small the request is. They are a business who are reliable and always deliver as scheduled. Product quality is superb and installation was fast, efficient with the workforce being very mindful and creating limited mess on site (busy household)."
