Portsmouth is one of the most over supplied and complex little pockets of the United Kingdom for double glazing comapanies, and finding replacement windows in portsmouth can be a daunting experience, because the amount of choice can be simply overwhelming. At a glance there ares Portsmouth Glazing Services, 1st Call affordable Quality Windows and Repairs, BJH Windows and Conservatories, First Double Glazing, Safestyle, Anglian Home improvements and Everest all competing for double glazing business in Portsmouth, amongst dozens of others.

But how do you go about choosing a reputable company to go for. This is not a definitive list, because even companies that provide excellent windows may provide poor customer service, or vise versa. Whilst asking these questions won’t guarantee protection from a bad experience, they will certainly place you, the customer in a stronger position:

1) What is the deposit, and how is it paid? Aim to pay your deposit on credit card as this will offer you protection if the double glazing company go bankrupt, as many small glazing companies have in recent times.

2) What happens if the quote changes? Sometime double glazing companies decide that the intitial quote was an underestimation. In this instance, find out what happens to your deposit - is it returned if you do not want to pay the extra (in some reported cases companies in the Portsmouth area have demanded a 50% increase in the intitial cost, and some people think this is now a sales tactic by the double glazing companies.

3) Why are you offering me loads of allegedly time limited offers? If the salesman is offering many deals which only last for a day, or require you to sign there and then, be very weary that the product is the right one and that the price too is right. Many consumers in Portsmouth have reported problems with this kind of sales tactic.

4) What previous work can you see? Don’t just rely on the company to show you examples of their past work, but be proactive - ask neighbours, friends and workmates about their experiences with double glazing companies, and try and find one who comes recommended. This may take some driving around Portsmouth, but it is far better than paying out to a firm who are not reliable!
