I have been installing and surveying windows, doors and conservatories for over 10 years working for a large firm covering the South Coast and London. In 2013/14 I decided to branch out and I began John Priestley Installations (J.P.I)

I am a VEKA Approved Installer which means that I have been independently assessed to make sure that I install windows correctly and comply with their high standards - such as offering my customers a 10 year insurance backed guarantee (which protects customers in the event that I ever cease to trade).

As a local business I typically work on only one 'project' at a time so my customers have my total attention and focus. I complete each project myself with my team from start to finish. You can expect me to be on site throughout.  I never take on several jobs at the same time or hire teams in.

I am able to offer cost effective alternatives tailored to the customer including repairs and glass replacement only. 

I install lantern roof lights, soffits, fascia and guttering, bi-folding doors and conservatories.

I use the highest quality and energy efficient products including coloured PVC options.

I am fully insured and offer an insurance backed guarantee which protects my customers.
