positive review  I cannot recommend McMahon and Nagle windows enough . From the first meetings with Jennifer Higgins to the lads completing the job ( who were a pleasure to have in my home) the service was professional, and friendly at all times . Constant communication keeping me informed at all times , but also available to me if I had any questions etc . McMahon Nagle are competitive in price but what’s sets them apart, is firstly the product they supply, and secondly as important in my eyes CUSTOMER SERVICE !! Thank you for your excellent and professional service I am beyond happy with my installation 🙌🏻❤️🙌🏻

positive review  Excellent service end to end. The sales person (Jennifer) was exceptionally thorough and patient with all of our questions. Fitting was quick and tidy. Particularly liked the follow up call to the house to ensure there were no problems (which there weren't). Would highly recommend.
