How do you invoice for the work? Avoid at all costs a company that wants to be paid up front or demands a large deposit. A reputable, professional company will not demand such payment terms. Ensure that all payment agreements are included in your contract.

Bryant and Cairns will not request a penny until the installation has been completed.

What is exactly included in the quote? When looking over the quotations check to see what is exactly is included and what the extras may be.

Top Tip – Always make sure the quality of the product is like for like so for example the energy rating of the window is the same. This then gives a fair comparison and a possible indication of any hidden costs that may appear with some companies. Don’t compromise on good quality and service for the sake of saving a few pounds. At the same time make sure that timescales are also documented so you can plan around the small but necessary disruption when the company is on site.

How do you dispose of the old frames? Nowadays the majority of old upvc window frames can be recycled so to help conserve the environment it is a wise choice to go with a company that recycles the old frames in order to keep the home improvement industry more sustainable.
