Dolphin windows are a local, family run company. We don't employ salespeople, nor do we employ subcontractors with our installation teams. We firmly believe that staff members who see themselves as an integral part of the company undertake higher quality installations than installers who move from one company to another.

We pride ourselves on installing windows,doors and conservatories that offer the latest technological improvements in both energy efficiency and security, coupled with a low maintenance finish ,leaving you with time to enjoy your new windows and doors without having to spend any time maintaining them.

Between Joel and Paul (owner and general manager respectively) they have over 40 years combined knowledge in the industry, putting them in a unique position to offer advice and recommendations without ever being pushy or difficult. You will only ever be visited by Joel or Paul. As a guideline an average appointment takes between 30mins - 1hour, not the 3 hours plus some companies insist upon.
