Our Process

We take great pride in every job we undertake and are always professional.

We take great pride in every job we undertake right from our initial meeting to the very last stage of the installation. We are happy to give quotes on any sized property from 2 bedroom bungalows to multistory apartments and each property will be visited from a dedicated Alpha Windows team member who will get an understanding of what is required and measure the area for each product that is needed. We are happy to assist your decision and if there is anything that wont work then we will simply just tell you and give you an alternative option.

Once the original specification is designed, we will then get the products manufactured including every detail from colour finishes, glazing design, style and the functionality. A team of our professional window installers will install and test your products to ensure all the fittings and functionality is to a high standard and that you are happy with your investment.
