This I can justify and breakdown into multiple answers as everybody's needs are different. Firstly let me explain the brief job description of the person that would normally call on you. We much prefer to call them consultants, of whom are prepared to work unsocial hours normally late evenings and weekends whose job it is to advise customers on their product range, give the companies price to carry out the works and secure a valued contracts for their company (these thick skinned people are often the joke of many a comedian, TV program, newspaper or the general topic of conversation at some time in most peoples lives).
We feel we cannot cut much out of the quality of our product, our installations are carried out that we do not have many on going service calls or complaints. We cannot compromise on our standard of installation vehicles. We dare not use cheap rate labour. I cannot see what we are cutting out, our prices are competitive and we are a solvent company with many satisfied customers.
Our job is to secure orders for our company, if customer A is happy with a brief visit, ok we get an early day. If customer B wants to discuss rocket science related to the product (these can take longer) ok. Everybody has a different point of view, some people want more information. My personal view is once I have made an appointment to see a prospective customer, my time becomes theirs.
I am glad that we are not the cheapest quote you have been given. Its true many windows now do look the same, (possibly due to the introduction of the New building regulations April 2002 that now covers windows and doors). Many reputable suppliers products are compliant under the BBA certification on performance insulated sealed units carry the same glass and air caps, every manufacturer has a similar locking or hinge system all offer a choice of colour finishes.
I would firstly like to be shown around the property to view the areas the client is considering and take approximate measurements, (I would like to add at this stage that these measurements are only approximate for a pricing purpose). Being in the trade for so long after a while you can normally judge the size relating to the pricing matrix. This has concerned some people in the past, thinking that the windows will not fit. (Once an order is placed a detailed survey is carried out on a made to measure basis).
