Check out all window Guarantees and what it is they cover. A lot of companies now offer “insurance backed” guarantees. Most guarantees will give A 10-year cover on the frames but you may find that the cover for the double glazed unit is 5 years. Unless fitting wood windows where some guarantees now extend to 30 years.

When comparing window quotations check the specification again and again. Make sure you realize “like for like” you will find suppliers using the same PVCu extrusion or wood type window and the same low-e Pilkington Glazing unit but are they both Fensa or certass registered and do they have a worthwhile window and door guarantee in place such as CPA Consumer Protection agency.

Don’t accept the first price you are quoted for wood or upvc windows or doors. Get at least two estimates if you have the time get more. Research all of the options such as energy efficiency windows and high security doors. A good double glazing company will help you understand all of the options

Always check out your window and door suppliers reviews online , the most straight forward way is to type in your suppliers name along with the word “review” You may be surprised with the information you can learn it may influence your decision on a particular window company.

Our last tip is important. Do not be the Customer from HELL. To get the best out of any Replacement wood or upvc Window Supplier maintain a friendly but professional rapport. Do not assume that they will always be trying to get “one over” on you. Their advice may be in your best interests. If you appear defensive and untrusting – always assuming the worst of your supplier – the whole experience will be unpleasant for both you and the window/ door supplier. Be vigilant – but always prepared to listen to their advice – especially if problems occur.
